Studies show, for example, that if you point out common stereotypes to girls while they are solving maths problems, such as that "boys are better at maths", the actual performance of girls in maths problems in this context deteriorates. In my view, this is lost potential for everyone: boys and girls and adults.
In everyday life, (unconscious) prejudices are also common, such as the tendency to try to confirm made assumptions (instead of looking for something that contradicts them). Similarly, even babies prefer people who are similar to them, and this trend continues in adult life. These biases also have a number of advantages, but you should be aware of them if possible and consciously counteract them if necessary. Like all people, I myself naturally have biases. Incidentally, this also makes me humble and even more open. Because we are all in the same boat.
I think we can achieve more diversity of thought if we treat our counterparts with openness, tolerance and generosity. By this I mean: I am happy, for example, to make role models visible where both parents work and successfully combine this with a family. But that doesn't mean that traditional family models are any less valuable or relevant. I think our horizons should broaden in terms of ways of thinking and life models and not simply shift from one model to another and discard everything that has gone before.
