PSYCHOLOGY TODAY - Aug 7 - An article published last year suggests - surprisingly - that people may in fact be just as well served by swiping through headshots on Tinder. In this study, participants filled out a bevy of psychological questionnaires, measuring everything that might influence compatibility; personality, attachment style, values, and more. These participants then went on speed dates. The authors then attempted to predict whether two people would find each other particularly attractive - indicting compatibility. They used Random Forest algorithms; high-tech statistical techniques that power things like Netflix's recommender algorithms, and allowed the researchers to search for any possible combination of psychological factors that might lead two people to be particularly compatible. While there were a number of psychological factors that made people more attractive overall, they found nothing that could predict, ahead of time, whether two people would be particularly compatible with each other. This may show that researchers just aren't asking the right questions or there just isn't any way to tell ahead of time whether two people are going to be compatible.
