Expert ability can actually impair the accuracy of expert perception when judging others' performance

Larson, J. S., & Billeter, D. M. (2017). Adaptation and fallibility in experts' judgments of novice performers. Journal of Experimental Psychology: Learning, Memory, and Cognition, 43(2), 271–288. http://dx.doi.org/10.1037/xlm0000304

These authors show that expert ability can actually impair the accuracy of expert perception in the context of judging the performance of others.

They had individuals with a range of singing experience rank-order recordings of different vocalists singing "Let it Go" from best to worst. The true quality of each vocalist was assessed by applying a Bayesian model to the ranking data, and then judgment accuracy was assessed by comparing these "true" rankings to those given by the judges.

Expert singers were less accurate than intermediate singers at determining the relative quality of low-quality vocalists. A subsequent experiment showed that experts notice more mistakes than intermediate or novice judges, and judge these mistakes more harshly.

The authors interpret these results in terms of adaptation level theory, which suggests that people are better able to discriminate at their own adaptation level. Thus, performance expertise increases the ability to discriminate among top performers, but this reduces the ability to discriminate among lower-level performers.

Complex trauma in childhood, a psychiatric diagnosis in adulthood: Making meaning of a double-edged phenomenon

Complex trauma in childhood, a psychiatric diagnosis in adulthood: Making meaning of a double-edged phenomenon. By McCormack, Lynne; Thomson, Sherilyn. In Psychological Trauma: Theory, Research, Practice, and Policy,  Vol 9(2), Mar   2017, 156-165.

Abstract: Objective: No known research explores the double-edged phenomenon of childhood trauma/adult mental health consumer. Therefore, whether receiving a psychiatric diagnosis in light of childhood trauma supports or impedes psychological wellbeing in adult life, is unknown. Method: Interpretative phenomenological analysis (IPA) provided the methodological framework. Data were collected through the use of semistructured interviews. Analysis sought thematic representation from subjective interpretations of the experienced phenomenon: childhood trauma survivor/mental health consumer. Results: Data revealed 1 superordinate theme, Childhood Betrayal, Identity, and Worthiness, that overarched 5 subordinate themes a) legacies, (b) the label, (c) putting the jigsaw together, (d) stigma, and (e) better than good enough self. Legacies of doubt that perpetuated “not good enough” delayed the development of an adult identity of worthiness in these participants. Importantly, the right diagnosis separated self as worthy-adult from self as traumatized child and facilitated positive change for breaking harmful cycles, self-valuing, and increased empathy, wisdom, and patience. Conclusions: Findings inform future research and therapeutic practice in regards to adult help seeking behaviors in light of childhood trauma, often postponed through fear of stigma associated with mental health diagnoses and services. Similarly, findings suggest that ameliorating wellbeing may be dependent on a therapeutic relationship in which accuracy or right fit of diagnosis provides a conduit for the client to disengage from self-blame, unworthiness, and “not good enough.”
