I'd like to advance an alternative hypothesis for the effective altruism/charitable donations data:
Aside from reversing the suggested causality (which we obviously can't test from this survey), the difference is pretty narrow, I don't really know enough about statistics to analyse how well the data supports one hypothesis over the other, and while I would be interested in knowing the answer, I'm not sufficiently interested to go and learn how to do that kind of analysis (if it's even possible from this data, which I'm unsure of). Is anybody able to come up with something?
It seems like the effect of effective altruism on charity donations is relatively independent from income.
If I do a straight linear model with predicts charity donation from effective altruism, the effect is 1851 +- 416 $. If I add income into the model the effect shrinks to 1751+-392.
Furthermore being a effective altruist doesn't have a significant effect on income (I tried a few different ways to control it).
