Not a fan of IQ as a measure, but it’s hard to quantify “intelligence” for the purpose of studies. All standard measurements tend to be biased in one way or another.

TLDR:

The researchers then analyzed the four specific dimensions of the detailed questionnaire. For economic libertarianism, socialism, and liberalism, the analysis again showed no statistical difference between the groups. Giftedness did not appear to push individuals toward or away from these specific ideologies.

However, a distinct pattern emerged regarding the dimension of conservatism. The researchers found an interaction effect between giftedness and sex. This means the relationship between intelligence and conservatism depended on whether the participant was male or female.

Specifically, non-gifted men scored higher on conservatism than gifted men. The non-gifted men were more likely to endorse values related to tradition and strict social order. Gifted men were less likely to hold these traditional conservative views.

This difference was not observed among the women in the study. Gifted women and non-gifted women showed similar levels of conservatism. The divergence was unique to the male participants.
