We already experience schadenfreude at the age of four
That last finding is particularly dispiriting since we often look to young children to give us hope for humankind – they are seen as the sweet and innocent ones who have yet to be corrupted by the grievances of adulthood. And yet many other studies show that very small kids are capable of some less-than-appealing adult-like emotions. For instance, a study from 2013 found that even four-year-olds seem to experience modest amounts of Schadenfreude – pleasure at another person’s distress, especially if they perceived the person deserved it (because they’d engaged in a bad deed). A more recent study found that by age six children will pay to watch an antisocial puppet being hit, rather than spending the money on stickers. Oh, and maybe you should forget the idea of children offering you unconditional kindness – by age three, they are already keeping track of whether you are indebted to them.

We believe in Karma – assuming that the downtrodden of the world must deserve their fate
On a related note, so strong is our inherent need to believe in a just world, we seem to have an inbuilt tendency to perceive the vulnerable and suffering as to some extent deserve their fate (an unfortunate flip-side to the Karmic idea, propagated by most religions, that the cosmos rewards those who do good – a belief that emerges in children aged just four). The unfortunate consequences of our just-world beliefs were first demonstrated in now classic research by Melvin Lerner and Carolyn Simmons. In a version of the Milgram set-up, in which a female learner was punished with electric shocks for wrong answers, women participants subsequently rated her as less likeable and admirable when they heard that they would be seeing her suffer again, and especially if they felt powerless to minimise this suffering. Presumably derogating the woman made them feel less bad about her dismal fate. Since then, research has shown our willingness to blame the poor, rape victims, AIDS patients and others for their fate, so as to preserve our belief in a just world. By extension, the same or similar processes are likely responsible for our subconscious rose-tinted view of rich people.
