it’s fine and valid to research whether people encounter improper bias in their careers, which is clearly often the case. But their discussion is incomplete without at least recognition of another possible partial cause of gender disparity in tech, the fact that many sexist anti-STEM cues are given to children at a much earlier stage, way before careers are even on the horizon. These cues are delivered by parents, teachers, parents of friends, other adults, and other children. Cues can be as subtle as a wide-eyed look while reacting to the news that Sally wants to be a programmer, where Joey gets no such wide eyes for the same news. Any study that overlooks that cause, in order to focus only on the causes highlighted in recent dramatic episodes, is an example of the phenomenon mentioned in the title of the book their chapter appears in: Groupthink.
