High-authoritarian politicians refuse psychology surveys more than lows do

Evidence

To summarize then, I do not believe that the RWA Scale means I have gotten from (roughly) a quarter of the caucus memberships would equal the means I would have gotten if everyone had responded. I suspect that High RWA Canadian legislators are less likely to answer surveys from psychologists than Lows are, other things being equal. Thus the mean in each party would probably go up if I had been blessed with a 100% response rate. But I do not think the differences between the parties would change much. If they did, the differences could well increase, not disappear (EOF, pp. — Bob Altemeyer, The Authoritarian Specter, 3400
