Anger is an evolutionary strategy that helps us deal with threats. It focuses our mind on the target, suppresses our fear and drives us to attack.
Anger is not evolution’s answer to generic “threats.” You don’t get angry at the saber-toothed tiger charging you. Rather, it is a response to threats to social cohesion. People who break the rules make us angry even when they don’t directly harm us. It’s why people find themselves yelling at pedestrians who cross against the light even when the delay to the driver is a matter of seconds.
That’s why politicians are angry: because they are trying to artificially create a sense of social cohesion in their coalition of voters.
