These warriors are usually thirstier for rank than other players. An analysis of warriorship in premodern societies discovered a positive relationship between conflict intensity and the status on offer for fighters. ‘Warriors are motivated to participate in warfare because of the possibility of rewards,’ it found. These included ‘increased status, honorific names or titles, or special insignia’. They’re also more likely to be collective narcissists: they believe their game is obviously superior and automatically deserving of deference.
