I once had the head of the TN Parole Board tell me he could make the repeat offender rate what ever he needed to by controlling WHO he released. They know who will be coming back and how soon, they release them any way.
Another source of wisdom on the reliability of science is the deluge of “scientific” studies about health and nutrition. You can find studies that prove everything causes and cures cancer, everything causes and cures obesity, just to name two conditions.
