Endogenous androgens show a moderate association with a better sexual function in women; however, the role of psychological, relational and other hormonal factors should not be overlooked

Maseroli E and Vignozzi L. Are Endogenous Androgens Linked to Female Sexual Function? A Systemic Review and Meta-Analysis. J Sex Med 2021;XX:XXX–XXX. https://doi.org/10.1016/j.jsxm.2022.01.515

Abstract

Background: The benefits of treatment with testosterone (T) in women with loss of desire suggest that low androgens may distinguish women with sexual dysfunction (SD) from others; however, evidence on this point is lacking.

Aim: To answer the question: is there an association between endogenous levels of androgens and sexual function in women?

Methods: An extensive search was performed in MEDLINE, Embase and PsycInfo. Four separate meta-analyses were conducted for total T, free T, Free Androgen Index (FAI), and Dehydroepiandrosterone sulphate (DHEAS). Cohort, cross-sectional, and prospective studies were included.

Outcomes: The main outcome was the association between endogenous androgens and sexual desire. Global sexual function was considered as a secondary outcome. The effect measure was expressed as standardized mean difference (SMD).

Results: The meta-analysis on total T included 34 studies involving 3,268 women, mean age 36.5 years. In 11 studies, a significant association was found between sexual desire, measured by validated psychometric instruments, and total T (SMD = 0.59 [0.29;0.88], P < 0.0001), with a moderate effect. The association with global sexual function (n = 12 studies) was also significant (SMD = 0.44 [0.21;0.67], P <0.0001). Overall, total T was associated with a better sexual function (SMD = 0.55 [0.28;0.82)], P < 0.0001), with similar results obtained when poor quality studies were removed. Age showed a negative relationship with the overall outcome. No differences were found when stratifying the studies according to menopausal status, type of menopause, age at menopause, use of hormonal replacement therapy, relationship status, method for T measurement, phase of the menstrual cycle or use of hormonal contraception. The meta-analysis of T derivatives (free T and FAI) also showed a significant, moderate association with sexual desire. In contrast, DHEAS seems not to exert any significant influence on desire, whilst showing a positive association with global sexual function.

Clinical Implications: Endogenous androgens show a moderate association with a better sexual function in women; however, the role of psychological, relational and other hormonal factors should not be overlooked.

Strengths & Limitations: This represents the first attempt at meta-analyzing data available on the topic. A significant publication bias was found for total T.

Conclusion: There appears to be a moderate association between total T and sexual desire/global sexual function, which is confirmed, although weak, in studies employing liquid chromatography-mass spectrometry (LC-MS). Similar results on desire were obtained for free T and FAI. DHEAS only showed a positive association with global sexual function. More research is needed.

Sexual incentive motivation, sexual behavior, and general arousal: Do rats and humans tell the same story? Anders Ågmo, Ellen Laan. Neuroscience & Biobehavioral Reviews, February 26 2022, 104595. https://doi.org/10.1016/j.neubiorev.2022.104595

Highlights

• Sexual motivation is activated by external stimuli called sexual incentives

• Exposure to sexual incentives leads also to enhanced general arousal

• General arousal enhances activity in the sexual central motive state

• Activity in the sexual central motive state requires the presence of gonadal hormones

• The determinants of interindividual differences in sexual motivation are unclear

Abstract: Sexual incentive stimuli activate sexual motivation and heighten the level of general arousal. The sexual motive may induce the individual to approach the incentive, and eventually to initiate sexual acts. Both approach and the ensuing copulatory interaction further enhance general arousal. We present data from rodents and humans in support of these assertions. We then suggest that orgasm is experienced when the combined level of excitation surpasses a threshold. In order to analyze the neurobiological bases of sexual motivation, we employ the concept of a central motive state. We then discuss the mechanisms involved in the long- and short-term control of that state as well as those mediating the momentaneous actions of sexual incentive stimuli. This leads to an analysis of the neurobiology behind the interindividual differences in responsivity of the sexual central motive state. Knowledge is still fragmentary, and many contradictory observations have been made. Nevertheless, we conclude that the basic mechanisms of sexual motivation and the role of general arousal are similar in rodents and humans.

5.3. Viscerosomatic responses and general arousal

Visceral responses, mainly genital blood flow, to sexual stimuli have been the subject of much research. It is possible that these responses are associated with enhanced general arousal. This could easily be shown by calculating correlations between the magnitude of the genital response (erection and vaginal lubrication) and typical indicators of general arousal such as blood pressure, heart rate, respiration frequency or the galvanic skin response. Although all these variables have been recorded in the same individuals in many studies (e.g. Suschinsky and Lalumière, 2012), reports of correlations are exceptional. In fact, there is only one study in which correlations between the genital response and heart rate and the galvanic skin response were calculated (Laan et al., 1995). Contrary to what could be expected, both vaginal pulse amplitude and vaginal blood volume during exposure to a pornographic movie segment were unrelated to heart rate and the skin response. This observation suggest that the intensity of genital arousal is not a main determinant of general arousal in women. The possible relationship between the intensity of the viscerosomatic response of erection and the level of general arousal has not been studied.

Whereas the effects of genital responses on general arousal is unclear, there are many observations regarding the inverse relationship, i.e. the effects of general arousal on genital responses. In fact, there is a reasonable amount of data available from studies that have employed objective measures of genital responses to explicit sexual stimuli after manipulations of the level of general arousal. In an elegant experiment by Cindy Meston (Meston, 2000) women were shown a sexual stimulus (pornographic movie segment) either when rested or after intense physical exercise. It is well known that exercise increases general arousal. The vaginal response to the movie segment was enhanced in the women having engaged in physical exercise, i.e. women with enhanced general arousal. Similar effects were found after treatment with ephedrine, an agonist at postsynaptic adrenergic α and β receptors (Meston and Heiman, 1998). Stimulation of these receptors enhances activity in the sympathetic nervous system, another arousal-producing event. Anxiety has also been found to increase the vaginal response to sexual stimuli (Hoon et al., 1977Palace and Gorzalka, 1990), and anxiety is thought to enhance arousal (Ramsey, 1943). Studies in men have also shown that enhanced general arousal, because of conditioned fear, leads to enhanced penile response to a sexually relevant stimulus (Barlow et al., 1983). Likewise, an emotionally arousing, non-sexual video fragment enhances the penile response to an ensuing pornographic video segment (Wolchik et al., 1980). Since enhanced response to a constant stimulus must be due to increased motivation, it can tentatively be concluded that increasing general arousal stimulates the activity of the sexual central motive state, hence sexual motivation, in men and women.

Although there are many studies supporting the conclusion above, it must be mentioned that an extensive review of the effects of anxiety on sexual responses found that the relationship may be more complicated (e.g. Bradford and Meston, 2006). Several studies have failed to find any effect at all of anxiety on genital responses (e.g. Elliott & O'Donohue, 1997Sipski et al., 2004) while others have reported decreased response (Masters & Johnson, 1970). Consequently, it is premature to make any firm affirmation concerning the influence of general arousal on genital responses in men and women.

Pupil dilation is a non-sexual response to many kinds of stimuli (reviewed in Einhäuser, 2017). When recorded during exposure to a sexual stimulus, it might be considered a visceral response to this stimulus. If young men and women are stressed and concurrently exposed to pictures with erotic content, the pupil dilation are larger than in the absence of stress, and the stress effect is larger for erotic pictures than for neutral pictures (Finke et al., 2018). The stress-induction procedure was found to increase blood pressure and heart rate, showing that general arousal indeed was enhanced. This study suggests that general arousal not only enhances sexual visceral responses to sexual stimuli, but also non-sexual visceral responses to such stimuli. We propose that this action is mediated by the sexual central motive state, and that the heightened pupillary response is indicative of facilitated cognitive processing of sexual stimuli.

The role of general arousal for the viscerosomatic responses in rodents is poorly known. Only one study has evaluated the consequences of enhanced general arousal for penile erection. Rats were subjected to an anxiety-inducing procedure, and erections stimulated by apomorphine were quantified. The anxiety procedure enhanced heart rate and mean arterial pressure, confirming increased arousal. The number of erections observed in these animals was reduced compared to controls (Brien et al., 2002). Even if these data are not conclusive, they suggest that there might be a negative relationship between increased general arousal and erection. Nevertheless, it is probably prudent to abstain from any conclusion until more data have become available.

A curious illustration of a possible relationship between general arousal and sexual responses is found in the association between yawning and penile erection in male rats. Prolonged observation has revealed that erection and yawning often coincides (Holmgren et al., 1985). A major function of yawning is to enhance general arousal in environments providing little stimulation (Baenninger, 1997), such as a rat’s home cage. The momentarily enhanced arousal leads to a genital response, suggesting activation of the central motive state. Whether the association between yawning and sexual activation also is present in humans is not known. Regardless of this, there are probably other, equally likely, explanations for the temporal coincidence of yawning and erection.

We know of no data concerning vaginal responses and general arousal in rodents. In the absence of more experimental evidence in favor of effects of general arousal on genital responses in males and females we propose that rats are different from humans in the way that variations in general arousal have variable effects on genital responses to sexual incentives.

There is an indirect way in which general arousal could affect human genital responses. The level of arousal is known to be a determinant of the efficiency of cognitive processing, in the way that moderate arousal facilitates processing whereas very low or very high arousal have deleterious effects (e.g. Lambourne and Tomporowski, 2010). The importance of cognitive processes for genital responses in men and women has been well established (Tavares et al., 2020). Interference with cognitive processing of sexual stimuli leads to reduced genital response. For example, while women were watching a pornographic movie, they were asked to perform tasks of increasing difficulty. The lowest level of difficulty were no task, and the highest level was a requirement to classify pairs of digits according to complex rules, and verbalize the result aloud (Salemink and van Lankveld, 2006). The classification rules were complex indeed: together the digits form a number; odd numbers under 50 are classified as A; even numbers under 50 are classified as B; odd numbers over 50 are classified as B; even numbers over 50 are classified as A (Salemink and van Lankveld, 2006, p. 182). The more difficult the task, the larger the reduction of the genital response. Similar data have been reported from a male sample (van Lankveld & van den Hout, 2004). Manipulations facilitating attention to sexual stimuli enhanced responses in men and women (Both et al., 2011Farkas et al., 1979). Perhaps the somewhat variable effects of arousal-enhancing procedures on human genital responses can be explained by their unintended, equally variable, effects on cognitive processing.

5.4. Transition from approach to copulation

In humans, the transition involves a conscious decision about whether to proceed with sexual activities or not to proceed. Decision-making is known to enhance general arousal (Johnson, 1963) as manifested in increased heart rate and galvanic skin response. Likewise, pupil dilation, an exquisite indicator of general arousal (Bradley et al., 2008) occurs during the decision process (de Gee et al. (2014) and references therein). It seems likely that the decision to pass from sexual approach behaviors to sexual activity leads to enhanced general arousal as other decisions do. The same should be the case for the contrary decision, not to proceed with sex. Even though the cognitive processes underlying the decision to engage in sexual activities are poorly known, some informed speculation is possible.

It seems that most humans will not initiate partnered sex without explicit or implicit consent from the partner. In fact, in Western societies, and probably in many others, sexual approaches and ensuing sexual activities are socially acceptable only between consenting individuals. Predictions about obtaining consent for sexual interaction are probably an important part of the initial transition from approach to further sexual activity. However important such predictions may be at early stages of sexual approach, these predictions must be confirmed before manifest sexual activities start. Thus, the approaching individual needs to determine whether the approached individual is consenting to sexual activity or not. There seems to have existed conflicting views on how consent or lack thereof is communicated to a potential partner. It now appears that the consenting individual uses direct or indirect verbal expressions as well as direct and indirect non-verbal cues to communicate consent (reviewed in Fenner, 2017). These strategies are also used in pornographic movies (Willis et al., 2020), which may be important since, for many young people, such movies have become the main source of sex education.

Men and women communicate consent in similar ways, and both sexes understand their partner’s communication equally well (Hickman and Muehlenhard, 1999), even in casual encounters (Beres, 2010). The fact that men accused of rape or sexual harassment frequently argue that they misunderstood the message from the non-consenting party can be considered a kind of unfounded self-justification (Maruna and Mann, 2006).

Provided consent is obtained, direct physical interaction between the approaching and approached individuals will usually ensue. This will further enhance general arousal (see below). The contrary outcome, the potential partner’s refusal of consent, may also lead to enhanced arousal, perhaps because of frustration. Even the act of refusing further interaction may lead to enhanced arousal. There is some indirect evidence for this (Chen et al., 2014Zhou et al., 2009). Thus, whatever the outcome, the transition process probably enhances general arousal, and consequently contributes to the activity in the central motive state. Possible consequences are that the rejected individual persists in approach behaviors even if the partner has declined, or that these behaviors become directed towards another individual. There is, however, no direct evidence for any of these alternatives. Enhanced arousal in the rejecting individual will probably reinforce some central motive state different from the sexual.

In rodents, the search for consent before initiating copulation does not seem to be of major concern. One reason for this may be that rodents are not sexually attracted to other individuals unless these others show unequivocal signs of being ready for copulation. We have carefully analyzed the sexual interactions between male and female rats in a seminatural environment, and we have found that sexually experienced males rarely approach a non-receptive female (Chu and Ågmo, 2015aChu and Ågmo, 2015bLe Moëne et al., 2020a). An example is shown in Fig. 3. Furthermore, a male almost never mount a female not showing paracopulatory behavior (Bergheim et al., 2015). Thus, the execution of copulatory acts on part of the male depends on the female’s behavior. Likewise, males need almost always to pursue the female before they come into position for executing a mount. In anthropomorphic terms we could say that the female rat invites the male to copulate, i.e. she expresses her consent to having sex, and the male can accept or not accept that invitation by pursuing or not pursuing the female. It appears, then, that sexual interactions among rats are limited to consensual sexual activities. This is not true in standard observation procedures, in which the experimenter subjects the rats to forced sexual interaction, but it is true in ecologically valid procedures, like the seminatural environment. In any case, whereas the transition from approach to copulation in humans is based on a conscious decision, there is no reason to believe that something similar occurs in rats. There, the transition appears to be an automatic process. Thus, there is no arousal-enhancing decision making involved.

7. Sexual and general arousal are intrinsically associated

In the preceding overview, we have tried to ascertain the potential role of several compounds in the long- and short-term control of sexual motivation, i.e. the activity of the sexual central motive state. Furthermore, we have described how these compounds may be affected by general arousal. One purpose was to find out whether there is a bidirectional relationship between actions on sexual motivation and actions on general arousal. Table 2 summarizes the results of this analysis. It appears that there is not any necessary coincidence between release caused by general arousal and effects on the central motive state neither in rodents nor in humans. Since data concerning the effects of altered general arousal on release of many of the compounds listed in Table 2 are lacking, this is a tentative conclusion. It may also be observed that the compounds known to be released during sex are also released by enhanced general arousal. This is not surprising, since sex enhances general arousal.

We have presented abundant evidence showing that whenever sexual responses are activated, general arousal is also increased. We have also shown that some compounds released during the exposure to sexual incentives simultaneously enhance sexual and general arousal. This coincidence is not surprising. In rats and humans, copulatory behavior involves substantial physical activity, in the form of coordinated activity in skeletal muscles. The level of general arousal is an important determinant of that activity. At the same time, copulation requires a series of specific genital responses. The main genital response in males is erection, in the human an entirely vascular response. In the rat, vascular erection is reinforced by contraction of the striated penile muscles. Furthermore, in the rat, activity in these muscles is necessary for achieving vaginal penetration, and they will also contribute to the expulsion of semen at ejaculation in rats and men. During the first phase of ejaculation, seminal emission, smooth muscles in the epididymis and vas deferens will propel spermatozoa into the urethra while other smooth muscle cells will expel the contents of the seminal vesicle and the prostate. These contents will form the bulk of the ejaculate. In females, the main genital responses are clitoral engorgement and vaginal lubrication. Interestingly, there is some evidence suggesting that these sexual responses may be activated outside of sexual contexts by extreme levels of general arousal (Sachs, 2007Sachs, 2008). What we could call “effective sexual motivation”, or momentaneous activity level in the sexual central motive state, is always a combination of sexual and general arousal, as we try to illustrate in Fig. 1. We have found no evidence for any difference between humans and rodents in this respect.

8. Are the differences between rats and humans more than trivial?

Another purpose with the description of the hormonal and transmitter responses to sexual stimuli or sexual activities or changes in the level of general arousal was to compare rodents and humans. Similarities would strengthen the popular notion that rodents can be used to predict effects of drugs on human sexual functions (Ågmo, 2014Ågmo et al., 2004Le Moëne and Ågmo, 2019). Important dissimilarities would question that notion. The summaries presented in Table 1Table 2 clearly suggest a strong similarity between rodents and humans. The neurochemical control of the sexual central motive state seems to have been highly conserved among mammals, and it should, consequently, be possible to make reliable predictions from one mammalian species to another.


A large majority of the population would respond positively to the discovery of microbial extraterrestrial life, independent of factors such as personality or political orientation

Kwon, Jung Yul, Hannah Bercovici, Katja Cunningham, and Michael E. W. Varnum, PhD. 2017. “How Will We React to the Discovery of Extraterrestrial Life?.” OSF Preprints. November 9. doi:10.31219/osf.io/rb5mj

Abstract: How will humanity react to the discovery of extraterrestrial life? Speculation on this topic abounds, but empirical research is practically non-existent. We report the results of three empirical studies assessing psychological reactions to the discovery of extraterrestrial life using the Linguistic Inquiry and Word Count (LIWC) text analysis software. We examined language use in media coverage of past discovery announcements of this nature, with a focus on extraterrestrial microbial life (Pilot Study). A large online sample (N = 501) was asked to write about their own and humanity’s reaction to a hypothetical announcement of such a discovery (Study 1), and an independent, large online sample (N = 256) was asked to read and respond to a newspaper story about the claim that fossilized extraterrestrial microbial life had been found in a meteorite of Martian origin (Study 2). Across these studies, we found that reactions were significantly more positive than negative, and more reward vs. risk oriented. A mini- meta-analysis revealed large overall effect sizes (positive vs. negative affect language: g = .98; reward vs. risk language: g = .81). We also found that people’s forecasts of their own reactions showed a greater positivity bias than their forecasts of humanity’s reactions (Study 1), and that responses to reading an actual announcement of the discovery of extraterrestrial microbial life showed a greater positivity bias than responses to reading an actual announcement of the creation of man-made synthetic life (Study 2). Taken together, this work suggests that our reactions to a future confirmed discovery of microbial extraterrestrial life are likely to be fairly positive.


When advising others, participants favored deontological options more, recommending these options over the more utilitarian options that participants chose for themselves

Abstract: The traditional focus in the moral decision-making literature has been on understanding when and why people choose a utilitarian option versus a deontological option. However, we suggest that when deciding between these two options, people prefer a third option: to seek out others’ advice—which raises the question, what advice do people give others who are faced with a moral dilemma? In a meta-analysis of responses to 50 unique moral dilemmas, furnished by undergraduates, online panelists, and passers-by, we compared 8,696 self-choice responses (from participants who decided what option they choose) with 8,548 advisor responses (from participants who recommended what option others should choose). We found that when advising others, participants favored deontological options more, recommending these options over the more utilitarian options that participants chose for themselves (d = .112). Our research shows that when people seek advice from others, the two cents they receive are a deontological sense. 


Impact of a sudden and unexpected nation-wide alcohol sales ban in South Africa: This causally reduced injury-induced mortality in the country by at least 14% during the five weeks of the ban; also found a sharp drop in violent crimes

CESifo Working Paper No. 9595. https://www.cesifo.org/en/publikationen/2022/working-paper/alcohol-violence-and-injury-induced-mortality-evidence-modern-day

Abstract: This paper evaluates the impact of a sudden and unexpected nation-wide alcohol sales ban in South Africa. We find that this policy causally reduced injury-induced mortality in the country by at least 14% during the five weeks of the ban. We argue that this estimate constitutes a lower bound on the true impact of alcohol on injury-induced mortality. We also document a sharp drop in violent crimes, indicating a tight link between alcohol and aggressive behaviour in society. Our results underscore the severe harm that alcohol can cause and point towards a role for policy measures that target the heaviest drinkers in society.

In academic environments: Evidence that pay transparency causes significant increases in both the equity and equality of pay, & significant and sizeable reductions in the link between pay & individually measured performance

The influence of pay transparency on (gender) inequity, inequality and the performance basis of pay. Tomasz Obloj & Todd Zenger. Nature Human Behaviour, Feb 10 2022. https://www.nature.com/articles/s41562-022-01288-9

Abstract: Recent decades have witnessed a growing focus on two distinct income patterns: persistent pay inequity, particularly a gender pay gap, and growing pay inequality. Pay transparency is widely advanced as a remedy for both. Yet we know little about the systemic influence of this policy on the evolution of pay practices within organizations. To address this void, we assemble a dataset combining detailed performance, demographic and salary data for approximately 100,000 US academics between 1997 and 2017. We then exploit staggered shocks to wage transparency to explore how this change reshapes pay practices. We find evidence that pay transparency causes significant increases in both the equity and equality of pay, and significant and sizeable reductions in the link between pay and individually measured performance.

Liberals perceive the stock market as a more dangerous and riskier place than conservatives, which explains liberals’ greater support for regulation of the stock market, and their greater opposition to privatization of Social Security

Fear and Loathing of Wall Street: Political Liberalism, Uncertainty, and Threat Management in a Dangerous Economic World. Michael Edem Fiagbenu,Thomas Kessler. Political Psychology, February 25 2022. https://doi.org/10.1111/pops.12805

Abstract: Conservatives perceive the world as a more dangerous and threatening place than liberals, which explains conservatives’ more cautious social behaviors and their greater support for policies (e.g., anti-immigration and harsher punitive measures) that aim to manage and reduce perceived threats and uncertainties. However, past research operationalized the “world” as a place replete with social and physical threats (e.g., street crimes and terrorism). Less attention has been given to the economic world, which is equally characterized by threatening events (e.g., corporate crimes, stock-market crashes). In four studies, we examined whether differences in appraisal of the economic world explain ideological differences in stock-market participation and neoliberal economic policy preferences. The findings reveal that liberals perceive the stock market as a more dangerous and riskier place than conservatives. This asymmetry explains liberals’ cautious investment behaviors, their greater support for regulation of the stock market, and their greater opposition to privatization of Social Security. We argue that liberals’ greater support for these policies serves to protect investors and the general public from the perceived harms of the economic world. Our findings suggest that the psychological processes underlying threat management and uncertainty reduction are similar for conservatives and liberals, but these processes are context dependent.

Sensitivity to Perceived Dangers in the Social and Economic World

The context- and content-dependent nature of the relationship between ideology and threat sensitivity can provide further insights into how conservatives perceive and react to different types of crimes. Here, we distinguish between two psychological contexts: the social world where social and interpersonal interactions occur and the economic world where interactions with corporations, financial markets, etc., transpire. Studies based on the Belief in a Dangerous World scale (Duckitt et al., 2002, p. 92)—a common measure used to assess beliefs about the uncertainties and dangers of social life—have consistently shown that conservatives perceive the social world to be a dangerous place where immoral people aim to rob, assault, and murder law-abiding citizens. This characterization suggests that the social world is a place replete with street crimes and terror (e.g., muggings, burglary, murder) and that conservative’s beliefs about the social world may be shaped by their greater sensitivity to physically harmful crimes (see Crawford, 2017; Eadeh & Chang, 2020). In contrast, white-collar and corporate crimes are widespread in the economic world (e.g., Ponzi schemes, bribery, embezzlements), and liberals are more concerned about these crimes and perceive them as more serious than conservatives (Kroska et al., 2019; Unnerver et al., 2008; Zimring & Hawkins, 1978). But it is unclear whether these differences shape liberals’ perception of the economic world as a more dangerous and threatening place.

Most street crimes including burglaries cause immediate bodily harm (Kopp, 2019). Even in cases when burglaries occur without physical harm, the resultant feeling of victimization triggers cognitive and emotional states similar to those experienced following physical assaults (Janoff-Bulman & Frieze, 1983). It is, indeed, true that street-crime victimization may sometimes create negative economic impacts such as replacement of stolen property, paying medical bills, or unemployment due to injury. However, one may argue that fears and concerns about street crime are probably determined by the perceived risks of physical victimization (proximal effects) rather than economic victimization (distal effects). By extension, ideological differences in perception of the social world as a dangerous place (Jöckel & Früh, 2016; van Leeuwen & Park, 2009) may reflect conservatives’ (vs. liberals’) greater sensitivity to physical threats (see also Napier et al., 2018).

In contrast, white-collar crimes commonly occur during interactions with the economic world. These crimes are sometimes perceived as more socially and economically harmful than street crimes (Cohen, 2016; Friedrichs, 2010; Lynch & Stretesky, 2001; Michel, 2015; Piquero, 2018). The socioeconomic harms created by white-collar crimes also differ qualitatively from street crimes. For example, unethical corporate practices sometimes lead to bankruptcies, market failures, and financial crises (Greenglass et al., 2014; Schoen, 2016; Shover & Grabosky, 2010). These negative events typically cause widespread economic harms (e.g., debt, unemployment, foreclosures, etc.), which endanger livelihoods (Rheinhart & Rogoff, 2009; Yilmazer et al., 2015). Corporate scandals and financial crises weaken trust in the economic world and increase fear and risk perception of financial markets, which in turn reduce participation in the stock market (Giannetti & Wang, 2016; Kuvvet, 2018; Lim & Kim, 2018; Nguyen et al., 2017; Zhou, 2020).

Although economic adversity may create secondary outcomes such as illness, injury, or even suicides (Chang et al., 2013; Lynch & Stretesky, 2001; Michel, 2015; Yilmazer et al., 2015), these distal physical outcomes are usually mediated by proximate economic victimization and moderated by socioeconomic status, preexisting physical or mental health, or even seasonal timing (Ballester et al., 2019; Haw et al., 2014; Margerison-Zilko et al., 2016). Consequently, it can be argued that people’s sensitivity to white-collar crimes is primarily driven by their perceived risks of economic rather than physical victimization. If correct, then liberals’ greater concerns about white-collar crimes suggests that they may be more sensitive to economic victimization than conservatives, which may likely cause liberals (vs. conservatives) to perceive the economic world as a dangerous and threatening place.

Threat Management and Uncertainty Reduction in the Social and Economic World

Since conservatives and liberals are sensitive to different types of perceived threats and dangers, one would expect that they would adopt unique behavioral coping strategies and embrace distinct public policies that are well-suited for threat management and uncertainty reduction. Relative to liberals, conservatives typically amend their lifestyles and restrict their social activities (e.g., reduce traveling, avoid crowds and unsafe places) to safe spaces to minimize their risk of physical victimization (Reinhart, 2017; Sloan et al., 2020). Conservatives also support harsher punitive policies (McCann, 2008), more government spending on street-crime prevention (Rebovich et al., 2000; Ren et al., 2008), and stringent anti-immigration procedures than liberals (Doosje et al., 2009; Stewart et al., 2019). The overarching aims of these policies are to resist perceived harmful social changes and regulate activities that are perceived to increase social disorder.

In contrast, liberals also engage in behaviors which may help to minimize economic threats. Liberals are more cautious and intolerant of financial uncertainties in real and hypothetical stock-market games and also form more negative attitudes towards stocks than conservatives (Fiagbenu et al., 2021a; Kaustia & Torstila, 2011; Moore et al., 2010). Although there appears to the an ideological asymmery in stock ownership, the effect sizes are, however, small or insignificant, (r = .01–.20); and the relationship is moderated by financial self-efficacy (Han et al., 2019). However, these studies, taken together, imply that relative to conservatives, liberals may avoid the stock market presumably because they perceive it as a threatening place. But empirical evidence in support of this assertion remains to be established.

Furthermore, liberals also adopt policies that help them to cope with economic threats. First, experimental manipulations that increase the salience of corporate scandals increase support for regulation of financial institutions (Eadeh & Chang, 2020). In addition, liberals are more likely to support punishment of white-collar crimes and call for more government spending on their prevention than conservatives (Kroska et al., 2019; Michel et al., 2014; Rebovich et al., 2000). Further, liberals are more likely to support tighter regulation of the stock market and corporations than conservatives (Potrafke, 2009; Unnerver et al., 2008). Finally, to protect low-income workers and other vulnerable groups, liberals (vs. conservatives) oppose risky economic policy reforms such as partial privatization of Social Security (Devroye, 2003; Rudolph & Popp, 2009). Thus, relative to conservatives, liberals’ support for these policies can be interpreted as a motivation to reduce the perceived harms caused by unregulated practices in the economic world. If correct, then one would expect that liberals would perceive the economic world as a dangerous and threatening place than conservatives.

Strong men are more inclined to casual sex; contrary to our predictions, socioeconomic status did not affect short-term mating orientation

Long-Term Mating Orientation in Men: The Role of Socioeconomic Status, Protection Skills, and Parenthood Disposition. Gabriela Fajardo et al. Front. Psychol., February 25 2022. https://doi.org/10.3389/fpsyg.2022.815819

Abstract: From an evolutionary perspective, phenotypic, social, and environmental factors help to shape the different costs and benefits of pursuing different reproductive strategies (or a mixture of them) from one individual to another. Since men’s reproductive success is mainly constrained to women’s availability, their mating orientations should be partially calibrated by features that women prefer in a potential partner. For long-term relationships, women prefer traits that signal access to resources, protection skills, and the willingness to share them. Using generalized linear models with laboratory data taken from a Chilean population (N = 197), this study aimed to test whether real and potential resources (measured as self-reported socioeconomic status), protection skills (measured as handgrip strength), and the willingness to provide resources and protection (measured as their disposition toward parenthood) are related to mating orientation in men. Our predictions were: (1) socioeconomic status would be positively associated with long-term and short-term mating orientation but for long-term-oriented individuals, this would be enhanced by having a more favorable parenthood disposition and (2) strength would be positively related to long-term mating orientation in men with higher socioeconomic status and a favorable disposition toward parenthood and it would have a positive and direct association with short-term mating orientation. Our results partially supported the first hypothesis, since men with higher socioeconomic status were more long-term oriented, but parenting disposition did not moderate this effect. Contrary to our expectations, socioeconomic status was not related to short-term mating orientation. Strength appeared not to be significant for long-term mating orientation, even interacting with other traits. However, strength by itself was powerfully linked with a short-term mating orientation. Our results suggest that only some individuals that are attractive for long-term relationships are indeed long-term oriented and may reflect the overall conflict of interests between mating strategies among sexes.

Discussion

The SPH proposes that the relative allocation of time and energy between mating and parenting activities is facultatively calibrated by an individual’s particular traits and social context. In this regard, men showing traits preferred by women for long-term relationships should display higher sociosexual attitudes toward long-term mating (Gangestad and Simpson, 2000Buss and Schmitt, 2019). Previous studies reporting associations between traits preferred by women for long-term relationships and men’s sociosexuality are scarce, do not specifically address the mentioned issue, and use a unidimensional approach to sociosexuality (Townsend, 1993Sprecher et al., 2013Szepsenwol et al., 2017). In this study, we tested whether economic resources, protection skills, and the willingness to allocate these resources in offspring—all traits preferred by women in long-term partners—are associated with men’s long-term mating orientation. Our results partially supported our predictions as we found that socioeconomic status was positively associated with a long-term mating orientation, but parenthood disposition did not moderate this effect. Instead, parenthood disposition seems to mediate this effect. Contrary to our predictions, socioeconomic status did not affect short-term mating orientation. Moreover, we failed to find the expected effects of strength on long-term mating orientation, but we found that strength was positively associated with short-term orientation.

Our first specific prediction was aimed at testing the effect of economic resources on long and short-term mating orientation and whether the willingness to allocate resources in offspring was moderating the effect for long-term oriented men. Regarding main effects, we found that resources, measured by socioeconomic status, were positively related to long-term mating orientation but did not affect short-term mating orientation. This result is aligned with previous studies that found the possession of resources attractive for women when choosing a long-term partner (Townsend, 1989Buss et al., 1990Sprecher et al., 1994Buunk et al., 2002Blossfeld and Timm, 2018) and support our prediction that resources are important in calibrating long-term mating orientation in men. In addition, our null result regarding short-term mating orientation is similar to the results of Sprecher et al. (2013), in which socioeconomic status was not related to short-term mating strategies but differs from the findings of Townsend (1993) that found a positive relationship. Our prediction regarding the positive relationship between economic resources and short-term mating orientation in men was based on previous evidence suggesting that economic resources may be a relevant trait for women when choosing a short-term mate (Greiling and Buss, 2000Thomas and Stewart-Williams, 2018). But this preference for economic resources in short-term mating might be related to context-specific traits as when women meet a potential mate with higher socioeconomic status than their current partner (Greiling and Buss, 2000) or when the environment is high in resources (Thomas and Stewart-Williams, 2018). This circumstance may explain why, in a general context, economic resources seem to be related to long-term mating orientation in men but not to short-term mating orientation.

As important as resources are for women who seek long-term relationships, there are personality features that signal a willingness to allocate them to one partner and their offspring over a significant period (Buss, 2018Webb and Fisher, 2018). In this regard, parenthood dispositions denote the willingness to invest in offspring and it is considered a component of men’s mate value which is especially relevant to attract partners for long-term relationships (Fisher et al., 2008). Accordingly, we expected that parenthood dispositions would moderate the effect of resources in the expression of long-term mating orientation in men. However, our results did not support this prediction, suggesting that socioeconomic status influences long-term mating orientation independently of parenthood dispositions. Since socioeconomic status and parenthood disposition were correlated in this study, we explored the possibility that parenthood disposition was mediating the relationship between socioeconomic status and long-term mating orientation. We found that indeed this was the case, suggesting that socioeconomic status affects long-term mating orientation through an increase in parenthood disposition. Future studies are needed to confirm that result due to its exploratory nature in this study.

Our second specific prediction was focused on testing the effect of protection skills on long and short-term mating orientation. In this regard, previous literature did not find an association between protection skills (i.e., strength and muscularity) and long-term sociosexual orientation, but it did for short-term (Lukaszewski et al., 2014Polo et al., 2019). We proposed that this feature might have a positive effect on long-term mating orientation when interacting with other variables relevant for this context, like socioeconomic status and parenthood dispositions, and a direct and positive effect on short-term mating orientation. In line with previous research (Lukaszewski et al., 2014), strength predicted short-term but not long-term sociosexual orientation in men. However, contrary to our prediction, we did not find an effect for the proposed interaction between strength, socioeconomic status, and parenthood disposition. Thus, our results suggest that protection skills, measured from handgrip strength, do not seem to be a relevant factor that calibrates men’s long-term sociosexual orientation despite being described as relevant for women when choosing a long-term partner (Buss and Schmitt, 2019). A possible explanation is that, since it has been documented that protection skills are attractive for women in both mating contexts, men who display these traits may be attracting a larger pool of women and may gain more by pursuing a short-term mating strategy, maximizing the number of sexual partners (Hughes and Gallup, 2003Frederick and Haselton, 2007Lukaszewski et al., 2014Polo et al., 2019). That can be particularly true in the case of men around their reproductive peak, as is the case of our sample, which was composed of young men with an average age of 22 years old. Finally, it is interesting to emphasize that strength is positively related to short-term mating orientation and has a null, but not negative, effect in the expression of long-term mating orientation. Strength has been associated with the possession of good genes and the ability to win a conflict (Sell et al., 2009), traits that are beneficial when pursuing a short-term mating strategy (Gangestad and Simpson, 2000). Consequently, it seems to be an important factor in calibrating short-term mating orientation but, according to our results, it did not affect long-term mating orientation. That suggests that a long-term mating orientation is not necessarily an alternative strategy employed when individuals cannot maximize their reproductive success through investing in casual sexual encounters. In addition, our results suggest that pursuing a short-term mating orientation by stronger men does not affect their orientation toward long-term mating and stress the importance of considering sociosexual orientation as a multidimensional construct.

To sum up, our results suggest that long-term-oriented men only display some of the traits that women prefer in them for long-term mating contexts, since resources but not protective skills are important for men’s long-term sociosexual orientation. Previous results showed that most of the traits preferred by women for short-term relationships are important in calibrating the expression of short-term mating orientation in men (Lukaszewski et al., 2014Valentine et al., 2014Polo et al., 2019). However, our results are less clear about the link between traits preferred for long-term mating and the expression of long-term mating orientation in men. This may indicate that, at least some individuals who possess traits reported to be attractive for long-term relationships, may be pursuing a short-term mating strategy instead. Possibly, this reflects the overall conflict of interests between mating strategies among the sexes that arise from differences in parental investment and potential reproductive rates (Trivers, 1972Parker, 2006). Complementary theoretical approaches to the study of reproductive trade-offs in humans such as the life history theory (Kruger, 2017) may be useful to understand this variability in sociosexuality in future studies. From this framework, one of the variables that has been reported to affect sociosexual orientation in adulthood is the developmental conditions and, especially, the predictability and harshness of the childhood environment (Ellis et al., 2009). Considering these developmental conditions jointly with current traits and conditions may help to have a wider understanding of the causes of the individual differences in mating strategies.

Our study has several limitations. First, our measure of parenthood dispositions which, although based on a subscale of a validated questionnaire (Fisher et al., 2008), might be too general as it was composed of only two items and precluded delving into different sources of investment and commitment to offspring. Future studies should include more specific measures of parenthood dispositions to determine whether different types of investment in offspring influence the relationships between socioeconomic status and long-term mating orientation in different ways. Second, our sample mainly consisted of young men and with low variability in age. This precludes analyzing whether the association of traits and mating strategies changes as individuals age and consolidate their social status. Future studies should include a wider age range to address this issue, either by pursuing a larger sample or by quota sampling by age groups. Our third limitation is that we did not have information about whether the participants currently had children or not. Despite that our sample was composed mainly of young men, their paternal status may be relevant as there is some evidence suggesting that unrestricted sociosexuality is reduced during parenthood in men, but only in those that reside with their children (Gettler et al., 2019).
