ONE 'SIMMON MO': Almost Killed Brer Possum
It is a fallacy that prevents you from stopping the wrong activity, which you understand as inappropriate, as it gives you some benefits.
It is similar to the sunk cost fallacy in that the more we wait, the worse something becomes. Yet, in sunk cost, we want to retain the resources already spent on an activity we initially considered proper. In contrast, in one 'simmon mo,' we do not want to stop the activity we consider beneficial yet improper.
