Racist ratings linger in five-star systems — a thumbs up could fix that

01:14 A simple switch to reduce racist ratings

A study of almost 70,000 ratings showed that racial discrimination could be eliminated from an online platform by switching from a five-star rating system to a thumbs up or down. The platform connected customers to workers who performed home repair jobs, and prior to the shift people categorised by the study authors as ‘non-white’ had lower ratings and got paid less than their white counterparts. Through follow up studies the authors also showed that the five-star system allowed people to impart their personal opinions, whereas a thumbs up or down just focused them on whether a job was good or bad. The team hopes this could be an easy-to-implement shift to tackle racial discrimination.

14:05 An analysis of retraction hotspots

A Nature investigation has revealed where the most retractions come from, with hospitals in China and institutions in India and Pakistan topping the list. Retractions are a normal part of science and may be a sign of necessary scrutiny, but they can also signal misconduct and use of paper mills. Features Editor Richard Van Noorden joins us to discuss what this means for science and tackling sloppy research.
