You know there are other factors that influence the recidivism rate for both countries, but you’re ashamed to admit it because you know it detracts from your point.
You are ascribing a position to me that I don’t have.
Confounding factors exist in all studies. They don’t invalidate the results, but you have to control for them. All well designed studies do this. Why on earth would I think that they don’t exist?
You just won’t clarify what factors you want to talk about. Be specific and let’s see what research there is on it. Pointing to undefined factors and saying ‘…but other stuff!’ isn’t an argument in favor of your point, which was that “The main goal of prisons is to protect society from criminals by removing them and deterring others from committing crimes through fear of punishment.”
Nor have you provided any evidence for your point while I have provided links to several studies. Pony up some evidence for your argument or be prepared to learn and grow. Or remain stubbornly wedded to your incorrect opinion. Makes no difference to me.
