[quote]From the original article: [quote]Our results provide unique insights about human behavior in life-and-death situations. On the Titanic, the survival rate of women was more than three times higher than the survival rate of men (11). By investigating a much larger sample of maritime disasters than what has previously been done, we show that the survival rate of women is, on average, only about half that of men.[i] [b][u]We interpret this as evidence that compliance with the WCF norm is exceptional in maritime disasters[/u][/b][/i].[/quote]Basically, the size of the difference between male and female survival rates is big enough to conclude that the comparative strength advantage of men does not sufficiently account for the disparity.[/quote]I know they say that is how they interpret it but they haven't really said why they are justifed in doing so (just saying it's "big enough" isn't satisfactory to me). Granted, in most articles about statistics, the authors usually do a lot of hand waving since the articles themselves aren't meant to be peer reviewed. Another potential disparity is the fact that the crew may be more likely to be male than female.
