Two Stanford University researchers, Dr. Michal Kosinki and Yilun Wang have published a paper that claims that AI can predict sexuality from a single facial photo with startling accuracy. This research is obviously disconcerting since it exposes an already vulnerable group to a new form of systematized abuse.
The research can be found here https://osf.io/zn79k/ ,here https://psyarxiv.com/hv28a/ and has even been highlighted by Newsweek magazine here http://www.newsweek.com/ai-can-tell-if-youre-gay-artificial-intelligence-predicts-sexuality-one-photo-661643

My question is, as knowledgable members of the AI community, how can we scientifically debunk/discredit this research?
