Our implicit biases have been uncovered once again in a brilliant example. If a hurricane is named a female name, people are less likely to think it will be dangerous, so will be less likely to prepare for it...and consequently twice as likely to die!
This is not necessarily sexism in a bad form - it could simply be that people associate males with aggressively and females with emotions related to safety. A nice illustration of why policymakers need to understand more about human behaviour.
Female-named storms have historically killed more because people neither consider them as risky nor take the same precautions, the study published in the Proceedings of the National Academy of Sciences concludes. Researchers at the University of Illinois and Arizona State University examined six decades of hurricane death rates according to gender, spanning 1950 and 2012. Of the 47 most damaging hurricanes, the female-named hurricanes produced an average of 45 deaths compared to 23 deaths in male-named storms, or almost double the number of fatalities. (The study excluded Katrina and Audrey, outlier storms that would skew the model).
