When an ocean liner starts taking on water, what governs whether it’s “women and children first” or “every man for himself”? According to a report in the Proceedings¹ of the National Academy of Sciences, men’s altruistic² versus³ self-serving behavior depends on how quickly the ship sinks.

On the evening of April 14th, 1912, the Titanic⁴ hit an iceberg⁵ and took nearly three hours to slip beneath the waves. Some 1,500 people perished. And the survivors⁶ tended to be female or young. The Titanic’s women were over 50 percent more likely to make it than were the males, and children had a 15 percent better chance of being rescued than adults.

But kids were not as lucky on the Lusitania, which three years later sank just 18 minutes after being hit by a German torpedo⁷. In this situation it truly was survival of the fittest, with healthy young males being the most likely to live to tell the tale.

While passengers on the Lusitania panicked and scrambled⁸ for survival, scientists say that those on the Titanic had enough time to override⁹ their animal survival instincts and do the chivalrous¹⁰ thing.
