Your / Peterson's Eugenicist "argument" is refuted by the FACT that plenty of conservatives are creative.
However, that is only a strawman, and not what Dr. Peterson actually said (starting at 0:06): "Conservatives tend to be lower in openness, which is a trait associated with creativity; and higher in conscientiousness, which is a trait associated with industriousness and orderliness." He is describing statistical trends. Patterns. And there are outliers to every trend. But what you said does not actually refute his point.
If you're going to refute someone's argument, represent it honestly.
