Does the trait of “turning red when drinking alcohol” affect income? A study of 3,000 people including Japanese men was published in a 2023 academic journal by the University of Tokyo and others: Innovative Tech

Researchers from the University of Tokyo and other institutions surveyed about 3,000 employed men ages 25 to 59 in Japan, Taiwan, and South Korea.

Using an alcohol patch test to identify men who flush red after drinking, they compared drinking habits, income, and working hours.

Men with higher alcohol tolerance drank more, but they generally did not earn more or work longer hours.

A weak income advantage appeared only in South Korea, suggesting little evidence that drinking ability improves labor-market outcomes.
