This happens often enough that I'm going to post my latest example. Prompt: "Create a few icons that represent the concept "delegate." And (besides for them being a terrible "icons") almost all of the ones with people in them are white men in ties. Here are my five results of the same prompt – counting individually 64 men in ties (with only maybe 3 of them generic enough that they could be considered non-white) and only 3 women.
And sure – I can add further prompts saying specifically that I want to see women or people of color – but why is the DEFAULT to be white men? Adobe – I think you can do better.
