Does the brain possess mechanisms to spot a feedback loop of self-induced negative sensation and relief?
Professor Sweeney has expressed the hypothesis that counterfactual thoughts that follow a relief are an example of a such mechanism on the Hidden Brain podcast although it's not something she discussed in the paper which finds counterfactual thoughts to be a common aftermath of a relief. The podcast discussed an experience of a guy attacked by lions in a group and how such extreme sitations tend to be followed by euphoria and laughing that later feels chilling to the people who undergo them, making the euphoria feel like not worth the experience.
