Why they didn’t say the same about the 99% of the women who won competitions?
It makes up for a more believable story in this context (boxing which is accepted as a masculine sport) and therefore becomes a more efficient tool. It fits in more easily with people’s biases making it much easier to spread. Simon Biles is a gymnast so that does not fit into the context here. Grace Bullen does. But you can not simply say “it did not happen to other women in plausible scenerios, therefore it is not real”. It is like saying belts are useless in %90 of the cases, it is a useless statistic that does not take into account the expected effect.
I really don’t see how this measurement can lead to any conclusion.
What do you mean? Comparing the rate at which women are subject to such effects vs men is a worse statistic than saying “but many successful women are not subject to such effects”? If there is a systematic bias towards women’s success being downplayed, you cannot call this an isolated incident of stereotypical bias.
