Also, what set of ideas are you drawing from? There are a lot of uncontroversial and true ideas. (Or if you negate them, obviously wrong.) Why aren’t they “more likely?” I don’t know how you decide on the set of ideas to test without bias.
And how do you evaluate the results? To tell whether ideas that are “likely to be true” are more likely to make people upset, you need to already know whether they are true. Otherwise you’re just sorting by controversial.
Here’s a fun story about that: https://slatestarcodex.com/2018/10/30/sort-by-controversial/
Sometimes contrarians are right about things. But when they are they bring receipts. They have evidence, repeatable experiments, falsifiable hypotheses, and general academic rigor.
Flat Earthers aren't intimidating to anyone. They're tiring. Like all good conspiracy theories Flat Earth conspiracy theories are unfalsifiable. The Flat Earthers' lack of evidence is defended by them as evidence of some sort of orthodox conspiracy. Evidence contrary to their stupid ideas, including empirical observations, are also just labeled as some orthodox conspiracy.
It's not edgy, funny, or even interesting. It's just fucking stupid. It's a handful of bad faith trolls and a lot of scientifically illiterate boobs that decided to wrap their identities around Internet memes.
You're right. Except that you seem to be implying that the "marketplace of ideas" optimizes for worthwhile ideas, rather than ideas that simply make people feel good - despite being terrible in practice, overly simplistic, fallacious, logically incoherent, etc.
These two qualities used to be in much closer alignment when the Internet was dominated by logical types who would at least try to get to the truth of things, modulo that everpresent lure of feeling superior by knowing something that bucks the common narrative.
But at this point we've devolved to full on Gresham's law as applied to ideas. Anything that carries the slightest bit of nuance or reservation demands analysis (slow path) rather than simple team allegiance (fast path). This is multiplied by the dynamic of sharing things verbatim - either quoted or by reference (URL) - which allows one to effortlessly propagate memes while disclaiming attachment to their own reputation.
Self sorting directly supports the dynamic I described, because feel-good terrible memes don't fool everyone uniformly. Look at both political herds - each baited with acknowledgement of specific real problems, and then mostly misdirected into avenues that rage against nonsensical bogeymen. It's utterly anti-productive and often self-harming, but it sure makes the participants feel good.
The "elites" want you to move in their preferred direction, yes. But much of that bearing is just common sense - so pushing in the exact opposite direction out of spite puts you further behind and suits them just as well.
If you actually want to actually assert your own independence, you have to do the excruciating work of using reason to figure out the right direction to push that actually represents your own self interest.
