Keep your eye on the intuitions, and don’t take people’s moral arguments at face value. They’re mostly post hoc constructions made up on the fly, cra… - Jonathan Haidt

Does helping others really confer happiness or prosperity on the helper? I know of no evidence showing that altruists gain money from their altruism, but the evidence suggests that they often gain happiness. People who do volunteer work are happier and healthier than those who don’t; but, as always, we have to contend with the problem of reverse correlation: Congenitally happy people are just plain nicer to begin with,24 so their volunteer work may be a consequence of their happiness, not a cause. The happiness-as-cause hypothesis received direct support when the psychologist Alice Isen25 went around Philadelphia leaving dimes in pay phones. The people who used those phones and found the dimes were then more likely to help a person who dropped a stack of papers (carefully timed to coincide with the phone caller’s exit), compared with people who used phones that had empty coin-return slots. Isen has done more random acts of kindness than any other psychologist: She has distributed cookies, bags of candy, and packs of stationery; she has manipulated the outcome of video games (to let people win); and she has shown people happy pictures, always with the same finding: Happy people are kinder and more helpful than those in the control group.

it would explain why extreme partisans are so stubborn, closed-minded, and committed to beliefs that often seem bizarre or paranoid. Like rats that cannot stop pressing a button, partisans may be simply unable to stop believing weird things. The partisan brain has been reinforced so many times for performing mental contortions that free it from unwanted beliefs. Extreme partisanship may be literally addictive.

Several of the peculiarities of WEIRD culture can be captured in this simple generalization: The WEIRDer you are, the more you see a world full of separate objects, rather than relationships.
