Not ideal
Showing people in stereotypical roles, e.g. international students as a group of people with different skin colors or scientists exclusively as men in lab coats; depicting people from marginalized groups, but only passively, out of focus or at the edge of the picture, while white men are shown in active roles.
The illustration of the topic of family or compatibility only with women and toddlers should also be avoided. These stereotypical representations restrict the view of role diversity and reproduce common prejudices, while the reality is much more differentiated.
Recommendation
Find out about common stereotypes in connection with science, gender and diversity, for example in suitable research articles. Question the first and spontaneous image ideas—how stereotypical are they? Do they help with understanding or are there other possibilities? For example, can specific people be shown in portraits alongside the presentation in the laboratory?
People should also be shown in roles that break with stereotypes, e.g. female professors in STEM fields, male secretaries, fathers with children, older students. The composition of the image can also help here, for example by showing people with different diversity characteristics together at eye level, on an equal footing and acting.
