I agree vegetarian diets are morally and ecologically superior, but this table is not very reassuring when it comes to how they affect infants' growth. Any intervention that results in persistent growth delays across measures should raise some eyebrows. jamanetwork.com/journals/jam...

Prevalence and Correlates of Psychopathy in the General Population | Journal of Personality Disorders Psychopathy encompasses a constellation of personality traits—including callousness, boldness, and disinhibition—associated with lifetime outcomes such as criminal activity, substance use, aggression,...

And with enormous thanks to Lisa Heidi Michael, my co-founder of the Society for the Prevention of Disorders of Aggression (SPDA) for funding this research.

Disinhibition predicted both criminal behavior and general antisociality. Meanness predicted more antisociality (STAB) and boldness predicted more criminal behavior (CAB). These relationships were not moderated by current household income.

Consistent with a general 'p' factor of psychopathology, we found fairly high correlations between the 3 subscales of psychopathy and other types of psychopathology. As has been previously shown, a high boldness boldness score is protective against some mental health symptoms.

All participants were recruited from the general community. It makes sense to ask: what would antisocial behavior look like in very high scorers? The answer: very high. High scorers are much more likely to report having committed crimes and other serious antisocial behaviors.

Here is the distribution we found (shown as deciles). Women are very overrepresented at the low end of the distribution. Men are more likely to have very high scores. A TriPM score of 105+ puts a male in the top 5% of males; a score of 91+ puts a female in the top 5% of females.

What is the average level of psychopathy in the community? How many of the people around us have very high levels of psychopathy? What are they like? Katie Berluti, Heather Doherty, Montana Ploe, Danielle Jones, Chris Patrick, and I assessed psychopathy in a quasi-representative sample to find out.

Mice seen giving 'first aid' to unconscious companions Young mice seemingly attempt to revive an anaesthetised cage mate by grooming and biting it and will even pull aside the tongue to clear its airway

When they find another mouse unconscious, some mice will attempt to revive their companion by pawing at them, biting and even pulling their tongue aside to clear the airways.
