I haven't seen the book Dave mentions. But I suspect whatever it says cites these *games*. It's basically antithetic to the idea that the truth will win out over time/evolution. I.e. trust in the progress of metaphysical ideas is misplaced. Coincidentally, I found this article interesting: Anti-Realist Pluralism: a New Approach to Folk Metaethics https://link.springer.com/article/10.1007/s13164-019-00447-8 > Abstract > > Many metaethicists agree that as ordinary people experience morality as a > realm of objective truths, we have a prima facie reason to believe that it > actually is such a realm. Recently, worries have been raised about the > validity of the extant psychological research on this argument’s empirical > hypothesis. Our aim is to advance this research, taking these worries into > account. First, we propose a new experimental design for measuring folk > intuitions about moral objectivity that may serve as an inspiration for > future studies.

This finding suggests that the > realist presumptive argument may have to be rejected and that instead > anti-realism may have a presumption in its favor.
