Soft sciences like psychology are usually based only on theories that suggest things, and don&#x27;t really adequately (at least to hard scientific standards) provide support aside from studies which rarely, if ever, have proofs. I could have linked the studies that are referred by the wikipedia page, but ain&#x27;t nobody got time for that. But I&#x27;d also be interested in seeing examples of true altruism, if anyone is capable of providing them.
