Higher-authoritarian legislators were less likely to respond to the survey

Evidence

We also know that usually, the greater the response rate from a chamber, the greater the gap between Democrats and Republicans. The correlation between response rate and the size of this gap averaged .69. So it seems probable that (1) High RWAs responded less than others did, and (2) if I had heard from all, the parties would have separated more than they did, not less. — Bob Altemeyer, The Authoritarian Specter, 3691
