Part 3/7:

One of the intriguing topics brought up by Peterson is the relationship between IQ and disgust sensitivity. His findings suggest that people with higher IQs tend to be less sensitive to disgust compared to their lower-IQ counterparts. This observation leads him to speculate about the underlying neurological factors that might contribute to such a dissociation—possibly involving the functional integrity of the cortex versus the emotional responses routed through the limbic system.

However, he notes an inconsistency: high IQ does not necessarily correlate with lower impulsivity. It becomes apparent that a high IQ does not equate to better self-regulation or behavioral control, as some highly intelligent individuals might still exhibit disorganized behavior and impulsive decisions.
