high T + low average IQ is a nasty combination. Add to the fact that they know they are at the bottom of the racial dating pool, making them bitter.
It's hard for low IQ people to self-regulate their actions and behavior, and are more guided by the lizard part of their brain --- so if they're annoyed with someone they'll just start screaming or swinging, possibly killing, not thinking steps ahead as to what consequences that'll bring. Or just feel like blasting music in public and not able to understand how this annoys people around them; they are genuinely too stupid to understand that.
Low IQ also makes it difficult for them to analyze a situation - for example, say at a restaurant, where you have to wait to be seated, and while the sheboons are waiting, a group of people walks in and are seated right away...they'll lose their shit, claiming "dey be rayciss", when in fact, the group that just sat down might have been waiting 30 minutes before they arrive and were texted. Niggers overall, regardless of gender, perceive simple mistakes as malicious slights
