Improving scale reliability strengthens Quest’s observed link to prejudice reduction

Evidence

McFarland (1989b) added four items to the Quest Scale (including one contrait), increasing its alpha from . to .70, and moving the prejudice correlations from the range of —. to —.31, up to the range of —. to —.40. Similar improvements were obtained in McFarland 1990. — Bob Altemeyer, The Authoritarian Specter, 2059
