“The Self-Reported Moral Behavior of Ethics Professors”, 2011-03-16 (; backlinks; similar):
We examine the self-reported moral attitudes and moral behavior of 198 ethics professors, 208 non-ethicist philosophers, and 167 professors in departments other than philosophy on eight moral issues: academic society membership, voting, staying in touch with one’s mother, vegetarianism, organ and blood donation, responsiveness to student emails, charitable giving, and honesty in responding to survey questionnaires. On some issues we also had direct behavioral measures that we could compare with self-report.
Ethicists expressed somewhat more stringent normative attitudes on some issues, such as vegetarianism and charitable donation. However, on no issue did ethicists show statistically-significantly better behavior than the two comparison groups.
Our findings on attitude-behavior consistency were mixed: Ethicists showed the strongest relationship between behavior and expressed moral attitude regarding voting but the weakest regarding charitable donation.
