Mental Attitude: Does IQ Determine How Much Alcohol a Young Man Drinks?

Swedish researchers have found that lower male IQ scores are linked to greater risks for heavy and binge drinking behaviors. The research team separated the nearly 50,000 male study participants into nine groups based on IQ scores from highest to lowest. They found that the risk of heavy drinking increased 20% and the risk of binge drinking increased 9% as they moved each level downwards towards the group with the lowest IQ scores. While it’s believed that many factors may influence an individual’s alcohol consumption, those with higher IQ scores may be more likely to make lifestyle choices that would steer them clear of situations that encourage heavy drinking.
