Agreed. You may also enjoy this psilocybin study that was released last week: http://www.newswise.com/articles/johns-hopkins-study-probes-...

> Altruism: Comparing LD-SS to HD-SS, the effect size was 1.36, which statisticians consider “very large.” Comparing LD-SS to HD-HS, the effect size was 1.95, considered “very large,” almost “huge.”

Psilocybin seemed to cause 'very large' increases in altruism.
