The next time you are plagued with indecision and need a clear way out, it might help to get angry, according to a surprising new study.

Despite its reputation as an impetus to rash behavior, anger actually seems to help people make better choices—even aiding those who are usually very poor at thinking rationally. This could be because angry people base their decisions on the cues that "really matter" rather than things that can be called irrelevant or a distraction.

Previous research has shown that anger biases people’s thinking—turning them into bigger risk-takers and making them less trusting and more prejudiced, for instance.

In both studies, the researchers found that the angry subjects were better at discriminating between strong and weak arguments and were more convinced by the stronger arguments.

Those who were not made to feel angry tended to be equally convinced by both arguments, indicating that they were not as analytical in their assessments. The angry students were also better at weighing the arguments appropriately depending on which organization had made them.

The researchers repeated the experiment a third time using a different argument—one that supported the implementation of a university-wide requirement for graduating seniors to take comprehensive exams. This time, they tested only those subjects who were the least analytical, or in other words, those who were the least likely to make logical decisions. This way, the researchers would be able to see whether anger also makes typically non-analytical thinkers more analytical.

Their findings, suggest that anger helps people focus on the cues that matter most to making a rational decision and ignore cues that are irrelevant to the task of decision-making.

This could be because anger is designed to motivate people to take action—and that it actually helps people to take the right action, the authors wrote.
