>The first study you link to doesn’t look at IQ, it looks at how people assess one another’s IQ, which is not the same. From the article I linked: "Each student in the picture completed a Czech version of the Intelligence Structure Test that uses various types of tools to measure the different types of intelligence. The images were close-ups of the students’ faces, which featured a neutral, non-smiling expression, and did not wear jewelry or cosmetics, Business Insider reported. The raters took their time rating each photograph for either intelligence or attractiveness. Of the raters, 43 women and 42 men judged photos for intelligence, and 42 women and 33 men judged them for attractiveness using a scale of 1 to 7 (1 being the highest score, 7 being the lowest possible score). The researchers then averaged the intelligence and attractiveness scores each student received. The findings revealed both men and women were able to accurately evaluate the intelligence of men by just viewing the facial photographs. Men in the photos with a higher IQ were perceived as more intelligent much more than women in the photos who also had higher IQ scores. In both sexes, a narrower face with a thinner chin, and a larger, prolonged nose characterized the predicted stereotype of a higher IQ, while a rather oval and broader face with a massive chin and a smallish nose led to a prediction of low-intelligence." Note the lines "Each student in the picture completed a Czech version of the Intelligence Structure Test" and " The findings revealed both men and women were able to accurately evaluate the intelligence of men by just viewing the facial photographs." So the study did actually measure peoples' IQs using a standardised IQ test, and compared the results of the tests to peoples' assesment of others' IQ based on their faces, showing a correspondence between the IQ people estimated based on faces and the actual IQ scores. Here's a study that directly shows a correlation between sexuality and facial anatomy: https://www.researchgate.net/publication/270290521_Facial_Structure_Predicts_Sexual_Orientation_in_Both_Men_and_Women https://www.researchgate.net/publication/270290521_Facial_St...
