The industry standard framerate for TV shows and movies is 24 fps. This creates the "movie" feeling that distinguishes a fictional product from a reality TV show like Cops. However, all smart TVs currently come with a feature with various names like "motion smoothing" that creates fake frames to "upscale" movies to 48 fps or 60 fps. This results in a bizarre visual effect that makes everything look closer to real life, so instead of enjoying suspense of disbelief you feel like you're watching a bunch of actors play dress-up in a backyard (which is what they are doing, yes).
Personally I can't stand this, I have no idea what kind of idiotic impulse led to its creation, and I try to turn it off every time I see it (which requires wading around in submenus because there's no industry standard name for it), but at this point I've run into multiple people who don't even seem to detect a difference between 24 and 48 fps. To me this is one of those things that make me question if some individuals are living in a different reality. I can't imagine watching an entire movie that's been "upscaled" to look like a AA-tier in-engine game cutscene.
Scaling anime fight clips to 60 fps and 4K has become a cottage industry on youtube as well. The best you can hope for is that it doesn't hurt the original content too much.
I find that ignorance or indifference to this is tied to a person's tolerance for slop like soap operas or Netflix originals. It's genuinely disturbing.
It's like the loudness war with music. Or thousands of other product decisions made because customers aren't discerning enthusiasts. More depressing examples include the bulk of home routers not having baseline security support (ideally open source firmware), and subscription enshittified cars. With home networking, you're not going to learn Broadcom chips suck from reading some Amazon reviews.
Despite a disappointingly conformist/normie concluding chapter, the Wisdom of Crowds book clearly outlines conditions a large group needs to make good decisions. There needs to be an apparent nontrivial individual penalty for the ordinary man making a weak decision. If people are copying another's solution, it needs to be verified how the original solution was made, or information cascades happen. It gets alot worse when a problem's ideal answer isn't trivially aggregated.
If faked refresh rates preferences were double blind a/b/control tested, and such a result mattered to brand reputation, interpolation=on default wouldn't fly.
I'm still an optimist that the internet can be a powerful mechanism for aggregation, but that requires much more exclusionary IRL societies. Imagine if governments were tracking Britney Spears listeners, not conscientious dissidents (i.e. not useful retard commies or loudly opinionated normies). Then we'd have a utopia where the market can do the bare minimum of choosing honest cars and TVs.
