"We also provide the first demonstration that model-predicted ideology connects to independently classifiable features of the face. For females (though not males), high attractiveness scores were found among those the model identified as likely to be conservative. These results are credible given that previous research using human raters has also highlighted a link between attractiveness and conservatism10. Recall that we use photographs provided by the candidates themselves while campaigning for (low-level) political office. Because attractiveness generally helps electoral success, all candidates are incentivized to provide an attractive photograph."
