The study's findings support the idea that violence played a significant role in shaping human evolution.
Researchers found that exposure to alcohol-related words increased aggressive behaviour following provocation when it was ambiguous or not clear-cut. The effects of alcohol priming are short-lived, diminishing after seven minutes and disappearing after 15 minutes.
The clinical validation study showed ProMark correctly identified low-risk disease with a sensitivity of 90% or better. The test provided additional independent prediction relative to standard risk-stratification systems, improving personalized treatment decisions for prostate cancer patients.

Habitual violent gaming is associated with long-term aggressive behavior in children, as measured by self-reported aggression and aggressive cognition. The study suggests that empathy does not mediate the effects of violent gaming on aggression.
Research suggests shame is a destructive emotion that hinders social connections. Professor Thomas Scheff argues that shame can manifest in larger conflicts like wars due to the reaction to it being hidden behind rationality. A good laugh is suggested as a way to resolve hidden shame, according to Scheff.
