I’ve been wondering about indirect IQ measurements. One of them, is… smoking. Yes, people still smoke tobacco in 2022. A lot of people. 🤢
Cigarette smokers have lower IQs than non-smokers, and the more a person smokes, the lower their IQ. For example, this study of over 20 000 Israeli military recruits.
And for the Believers in Emotional Intelligence™ pseudoscience, consider the phenomenon of “social smoking” and “smoking while drinking”.
