Survey self-selection bias hides the true Democratic-Republican authoritarianism gap

Evidence

We generally assume that the better the return rate, the truer the picture we see. So it would appear that the correlations would have been higher, not lower, if we had heard from everyone. You will find the same trend in nearly all of the subsequent studies, meaning self-selection bias has probably attenuated the true difference between Democrats and Republicans. The real gaps are even bigger. — Bob Altemeyer, The Authoritarian Specter, 3480 (#corroborates, via linked claim)
