As you can imagine, the study’s discoveries are bountiful, but the most significant finding of all is that “Alcoholism is a disorder of great destructive power.” In fact, alcoholism is the single strongest cause of divorce between the Grant Study men and their wives. Alcoholism was also found to be strongly coupled with neurosis and depression (which most often follows alcohol abuse, rather than preceding it). Together with cigarette smoking, alcoholism proves to be the #1 greatest cause of morbidity and death. And above a certain level, intelligence doesn’t prevent the damage.
With regards to income, there was no noticeable difference in maximum income earned by men with IQs in the 110-115 range vs. men with IQs above 150. With regards to sex lives, one of the most fascinating discoveries is that aging liberals have way more sex. Political ideology had no bearing on overall life satisfaction, but the most conservative men on average shut down their sex lives around age 68, while the most liberal men had healthy sex lives well into their 80s. Vaillant writes, “I have consulted urologists about this, they have no idea why it might be so.”
I remember reading about this back in April when the study was first released.
Personally, I’m most excited about comparing these results with those from a study ending 75 years from today.
How persistent is “what men need to live a happy life” — how culturally determined is it?
