I don’t think that’s correct. There’s a recent study showing a reduction in mortality for prisoners that are incarcerated relative to a control group of people who were not incarcerated. It appears that most of the reduction in mortality is from reduction in overdose death risk but also a reduction in homicide. The implication is that people in prisons are safer than they would be outside. Probably most of the data showing otherwise comes from poorly done studies that don’t use appropriate control groups, EG they may use the general population as control group relative to prisoners.

Most EA jobs I’ve seen offer health insurance, which usually includes a PCP.
Plus they can help with result interpretation, though GPT-4 does a pretty good job of that already.
