1) With the conventional alpha = 5% and a huge sample, you may have extremely high power for your effect of interest – say, 99.9%. That means beta (type-II error rate) = 0.1%. Are you sure that you want your type-I error rate to be 50x the size of your type-II error rate? >

Implicit racial attitudes accounted for ~2.5% of variance in behavior beyond explicit racial attitudes, an effect size that was *just* over our agreed upon threshold for what would constitute a practically significant effect. Explicit racial attitudes still explained much more variance (~45%).
