People have different experiences that may be relevant in ways you can't know because you didn't have them.

The classic example is the video of the black man showing the soap dispenser not working with his hand until he put a white piece of paper under it.

Parents, or people who take care of children (which is still mostly women), will have different ideas about when they may be available for things.

These are just two examples. You say discrimination is always a problem, but if a space is only full of one kind of person there may already be discrimination happening.
