We Have Evolved to Use Anger to Win

Men have adapted to deliberately use anger to gain advantage and get what they want. 

The scene was straight out of Brad Gilbert's bestseller Winning Ugly: Mental Warfare in Tennis.

During a brutal first-round match in 107 degree heat at the Australian Open, opponents Kei Nishikori and Marinko Matosevic each took prolonged bathroom breaks - but not at the same time. The key to winning ugly, as Gilbert would argue, is to make your opponent wait on the court in the heat. If your opponent does this to you, then you should take a break in retaliation and make them wait. While they seethe on the court, you come back fresh. You have then succeeded in annoying your opponent, and your unnerved opponent will start making mistakes. 

This is apparently a trick that men have adapted to use over time, as a new study demonstrates that men (only men were studied) deliberately anger each other to gain advantage and get what they want. 

According to a study published in the journal Proceedings of the National Academy of Sciences by Uri Gneezy, a behavioral economist at the University of California, San Diego, anger can be used strategically to impair an opponent's performance. Of course, anger can also be used to the benefit of a rival. If we sense that, we tend to shy away from the strategy.

Gneezy's study obviously has implications for negotiation. The rational course of action, it appears, is not always the most effective course of action.

Strange Maps
  • America's two political tribes have consolidated into 'red' and 'blue' nations, with seemingly irreconcilable differences.
  • Perhaps the best way to stop the infighting is to go for a divorce and give the two nations a country each
  • Based on the UN's partition plan for Israel/Palestine, this proposal provides territorial contiguity and sea access to both 'red' and 'blue' America

Water may be an inevitable result of the process that forms rocky planets

New research identifies an unexpected source for some of earth's water.

Surprising Science
  • A lot of Earth's water is asteroidal in origin, but some of it may come from dissolved solar nebula gas.
