Most of us have had the frustrating experience of being in a group that overlooked certain people’s ideas or didn’t give credit to the right person. In a recent study documenting this phenomenon, researchers sat in on 78 team meetings to see what happened to ideas — and the group members who contributed them — over time. They found that the group frequently overlooked ideas that members suggested, and sometimes revisited ideas later but gave credit to the wrong people. These findings are of particular concern to women, people of color, and members of other underrepresented groups, all of whom are especially likely to be dismissed or spoken over.
