Misplaced notions of manliness and invincibility may be motivating American men to ignore experts' guidance about masks and social distancing amid the COVID-19 pandemic, a new study suggests. The research, published Sunday in the in the peer-reviewed journal “Behavioral Science & Policy,” found women are more likely to report embracing expert-backed behaviors such as wearing a mask and social distancing. The study helps add credibility to previous research that resulted in similar findings, including that men were more likely to see masks as a sign of weakness.
