A recent comprehensive review of existing scientific research suggests that individuals who engage in impulsive acts of violence tend to score lower on intelligence tests compared to non-violent individuals. The findings provide evidence that lower intellectual abilities may make it harder for people to resolve conflicts peacefully, though intelligence is just one piece of a complex behavioral puzzle. The research was published in the journal Intelligence. Scientists from various disciplines have spent decades attempting to understand the underlying factors that drive aggression and violence. While past research provides evidence that lower cognitive abilities are linked to general criminal behavior, the specific relationship between intelligence and violent acts against others has remained less clear. This gap in knowledge prompted researchers to look closer at specific types of aggression. The researchers conducted the new review to figure out if people who commit violent acts consistently show lower intellectual abilities than those who do not. They also wanted to know if this pattern holds true for different components of intelligence, such as verbal skills and nonverbal problem solving. …
