EDITOR’S NOTE

The comments below are a sample of the outrage with which this news story was greeted. We are sorry that it has offended so many readers, but we stand by the piece. We strongly reject suggestions that it was motivated by bias or racism; our intention was to investigate the science behind a controversy arising from the current Olympic Games. The first paragraph states that Ye has never had a positive drug test and notes that much of the discussion of her win “has been tinged with racial and political undertones”.
The article is a fair-minded look at a controversy that we did not initiate. It asks whether new developments in performance monitoring could dispel the unfortunate suspicions that the most extraordinary athletic performance raises these days, whatever the nationality of the athlete.
We are no longer accepting comments on this news story, and because of the volume of comments, some early posts have disappeared. We intentionally deleted only those posts that violated our Community Guidelines.
