Formulation of the problem. There are very good people in this world, people who empathize with others, people who actively help others. Based onall the nice and helpful things that these good people do, one would expect that other people would appreciate them, cherish them, and that, in general, their attitude towards these good people would be positive. However, in real life,the attitude is often neutral or even negative. The resulting emotions hurt our ability to listen to their advice and thus, improve our decisions. Why? Is there a rational explanation for these emotions?

Common sense explanation. From the common sense viewpoint, the above mathematics makes perfect sense: A very good person is unhappy if other people are unhappy. If we empathize with this person, we become unhappy too, and since people do not want to be unhappy, they prefer (at best) to ignore others’ unhappiness – or even blame them for their own unhappiness.
