"Scientists from the Korea Advanced Institute of Science and Technology have confirmed that women fancy men who look like their brothers. To find out what people look for when rating potential partners, the experts analysed the interactions between more than 40,000 people on a major online dating platform. Using AI tools, the researchers were able to measure how similar users were in both facial features and personality traits."
"Using AI, the team analysed a total of 506,014 interactions betewen these users. The results revealed that when it comes to facial features, women prefer men who look like them. In contrast, men prefer facial dissimilarity - rating women more highly when their features were unlike their own. 'This result is consistent with the evolutionary logic of inbreeding avoidance,' the researchers explained in their study, published in Computers in Human Behavior."
A large-scale analysis used AI to measure facial and personality similarity across 41,441 South Korean dating-app users and 506,014 interactions. Women rated men who resembled their own facial features more highly, while men preferred facial dissimilarity. Parental investment theory was proposed as a possible explanation for women's preference, suggesting prioritization of trustworthiness and familiarity cues. Preference for dissimilar faces is consistent with inbreeding-avoidance logic to reduce genetic costs and increase offspring genetic diversity. Personality-based choices were most influenced by socio-economic status when assessing potential partners. AI tools quantified facial-feature and personality-trait similarity to enable the comparisons.
