I'm afraid that's the implicit bias in the AI. My prompt was:

'A mixed race lady dressed in a blue American Football kit jumps to receive a pass in the touchdown area. All other players are elderly white men in red.'

In the four images that came back, the mixed race lady was young, though I suppose that was by way of comparison for 'elderly' - and in one image she was wearing denim shorts which were highly unsuitable. I'd argue there's likely an implicit bias from the AU here - but one which society has a fair bit of responsibility for when we consider how athletic wear is marketed to men and women.

I've been watching the olympics it seems that for most sports there could be a single gender neutral outfit - but this doesn't appear to be the case in many sports. :o/
