League of Legends Rank Predicts IQ, Study Finds (plos.org)
limbicsystem writes: A new publication in the journal PLOS ONE shows that your rank in League of Legends (LoL) correlates with your intelligence quotient (IQ). Games like LoL and DOTA II apparently depend on the same cognitive resources that underlie tests of fluid intelligence. That means that proficiency in those games peaks at the same age as raw IQ -- about 25 -- while scores in more reaction-time based games like Destiny or Battlefield seem to decline from the teens onwards. The researchers suggest that the massive datasets from these online games could be used to assess population-level cognitive health in real-time across the globe. The authors have a nice FAQ (and open datasets) here. -
AI Can Detect Sexual Orientation Based On Person's Photo (cnbc.com)
ugen shares a report from CNBC: Artificial Intelligence (AI) can now accurately identify a person's sexual orientation by analyzing photos of their face, according to new research. The Stanford University study, which is set to be published in the Journal of Personality and Social Psychology and was first reported in The Economist, found that machines had a far superior "gaydar" when compared to humans. Slashdot reader randomlygeneratename adds: Researchers built classifiers trained on photos from dating websites to predict the sexual orientation of users. The best classifier used logistic regression over features extracted from a VGG-Face conv-net. The latter was done to prevent overfitting to background, non-facial information. Classical facial feature extraction also worked with a slight drop in accuracy. From multiple photos, they achieved an accuracy of 91% for men and 83% for women (and 81% / 71% for a single photo). Humans were only able to get 61% and 54%, respectively. One caveat is the paper mentions it only used Caucasian faces. The paper went on to discuss how this capability can be an invasion of privacy, and conjectured that other types of personal information might be detectable from photos.

Researchers Release Profile Data on 70,000 OkCupid Users Without Permission (vox.com)
An anonymous users shares a Vox report: A group of researchers has released a data set on nearly 70,000 users of the online dating site OkCupid. The data dump breaks the cardinal rule of social science research ethics: It took identifiable personal data without permission. The information -- while publicly available to OkCupid users -- was collected by Danish researchers who never contacted OkCupid or its clientele about using it. The data, collected from November 2014 to March 2015, includes user names, ages, gender, religion, and personality traits, as well as answers to the personal questions the site asks to help match potential mates. The users hail from a few dozen countries around the world. The researchers, Emil Kirkegaard, Oliver Nordbjerg, and Julius Daugbjerg ran software to "scrape" the information off OkCupid's website and then uploaded the data onto the Open Science Framework, an online forum where researchers are encouraged to share raw data to increase transparency and collaboration across social science.
