What term sums up the situation in which a person does not feel they have to weigh into (or put much effort) into an argument because the implications will not affect them?
Thus, person X debates for the motion that group A are a worse bunch of people than group B. However, person X knows that the reality is that group A will be economically and strategically less better off than group B for a long time to come regardless of any debate. Therefore, in a formal debate, person X is not as motivated to persuade the debaters against the motion of the merits of his arguments because he knows that it will not affect reality.
