When Sunita Nandihalli was a psychology graduate student at the University of Wisconsin-Madison, they and an undergraduate intern found themselves in an lift with a man who seemed fascinated with the intern. She was multiracial, and he repeatedly quizzed her about her hair.Nandihalli, a queer person of colour, had experienced similar obnoxious comments and stepped between the two of them, asking the stranger about his day and where he was going. "I had to take the intern's safety into account," they recall.Nandihalli knew what to do because of ADVANCEGeo, a project that trains researchers in how to intervene when they see bias and harassment in the geosciences. Nandihalli had lent their expertise to the project to adapt 'bystander-intervention training' programmes designed for office workplaces and make them relevant to research and academic settings. Funded by the US National Science Foundation and directed by three professional societies, ADVANCEGeo is one of a growing number of bystander-intervention training programmes at research and academic institutions 1 . They aim to stop harassment in its tracks and create a more welcoming workplace environment -particularly for women and minoritized people, who are leaving science, technology, engineering and mathematics in disproportionate numbers. A landmark 2018 report on sexual harassment in the sciences by the US National Academies of Sciences, Engineering, and Medicine (see Nature 558, 352-353; 2018) called for more bystander training in scientific workplaces. Research suggests that such programmes can improve the likelihood that bystanders will intervene, particularly when the training includes role play that helps people develop confidence to act. "In the past, a lot has focused on raising awareness on what bias and sexual harassment looks like, but we know that's not enough," says
BYSTANDERS CAN PUSH BACK ON BIAS AND BIGOTRYBystander-intervention programmes aim to train scientists in how to disrupt bias and harassment. By Sara Reardon Participants act out a sketch at a workshop designed to encourage researchers to step in when they see hurtful behaviour in the workplace.
