Raise a glass to the newest study in @ICAJournal from Maximilian Krolo and @timothycbates, who find that smarter people know more about wine. 🍷 In a sample of 525 respondents, IQ and wine knowledge were positively correlated (r = .31), and this relationship did NOT diminish after controlling for exposure to the wine industry or drinking habits. If you're not a sommelier, this correlation doesn't matter much in real life. But the study has a lot of theoretical importance. Wine knowledge is complex, sophisticated, not taught in schools, and has little practical application for most people. This undermines the theory that smarter people know more facts because they have economic incentives to learn more or because they attend school longer. The people who knew the most about wine were those who had both (1) high IQ and (2) exposure to the wine industry. This likely means that exposure to a knowledge domain occurs that smarter people benefit more from that environment than less intelligent people.
