I remember reading that people who were hypersensitive would avoid overstimulation.

Meanwhile, people with lower sensitivity needed more stimulation and became more prone to crime and risk taking.

I wonder if superfund sites decrease nerve efficiency leading to less stimulation and therefore risk taking.

EDIT:

A 2015 longitudinal study based on army medical records of Swedish men showed a correlation between low resting heart rate and violence and criminality, with the authors theorising that lower sensitivity to stimulation resulted in increased likelihood of risk-taking and sensation-seeking behaviour – effectively a low sensitivity counterpart to SPS."
