“LWer Effective Altruism Donations, 2013–2014”, 2015-05-12 (; backlinks):
Analysis of 2013–2014 LessWrong survey results on how much more self-identified EAers donate suggests low median donation rates due to current youth and low incomes.
A LW critic noted that the annual LW survey reported a median donation for “effective altruists” of $0, though the EA movement encourages strongly donations. I look closer at the 2013–2014 LW surveys and find in multiple regression that identifying as an EA does predict more donations after controlling for age and income, suggesting that the low EA median donation may be due to EAers having low income and youth (eg. being a student) rather than being unusually or even averagely selfish.
