There’s new science-backed evidence that diversity training workshops work. For a paper set to be published in the Journal of Experimental Social Psychology, researchers decided to test their experimental “prejudice habit-breaking intervention” at STEM (science, technology, engineering, and mathematics) departments where women are historically underrepresented. Women are almost half of the U.S. workforce, but they’re 39% of chemists, 28% of environmental scientists, and 12% of civil engineers. In fact, 40% of women engineers quit the field or will never use their degree.
