Once-and-For-Allism

 Tyler Cowen on the mistake of Once-and-for-allism.

I see once-and-for-allism with so many issues, but one recent example would be the forthcoming path of Covid and Long Covid.  Most people just don’t want to think about it any more, and so they settle on something (“it’s just a cold!” or “it will bankrupt the nation!”) rather than having to do lots of intellectual revisions based on the stream of new data.

Other examples of topics that attract once-and-for-all thinking would be crypto, demographic decline, long-run fiscal solvency, various foreign policy crises, biodiversity, AI issues, the Repugnant Conclusion and Non-Identity Problems, whether we are living in a simulation, UFOs, abortion, what is the person’s ultimate normative standard, and much more.

I would add the Libertarian notion that markets always work and if government is involved then it is wrong or bad. Maybe true ... if you don't think too hard about it.
