Reminds me of those posts from a few years ago that were like:
"[Simple math problem, like what's 5 x 4?]: 95% of people can't solve this! I bet you can't either!"
With hundreds of thousands of commenters "engaging" with it. I don't understand anything about this behavior. 1. What does the poster have to gain from a post like that, 2. What do all the commenters have to gain, and 3. What does SocialMediaCompany gain? The promise of social media is long dead. It seems to now just be bots (or people who behave as bots) responding to bots (or people who behave as bots)... everywhere.
Well, for (1) the poster gets engagement from low-effort posts. The end game is usually monetizing their social media presence, and though there's multiple ways to do that, they all involve getting eyes on your page.
Your (2) should be evident from the phrasing of your example: if 95% of people can't do it, people want to prove they're in the 5%. They get a few minutes' distraction, some self-satisfaction, and maybe some conversation. I'm not going to play psychologist, but that's enough for some folks. And it really only has to be some: if your post is seen 32 million people and 30 million dismiss it, you still got 2 million people to engage.
(3) is, I guess, money again? Active users means SocialMediaCompany can tout the value of their platform to advertising partners. The bot problem is a good observation, though, because platforms with a reputation for bots are less valuable to advertisers who want human attention. People who act like bots are probably great for advertisers, though, so idk; maybe that's a wash.
Those posts really are a curse. And they are usually not quite that simple, there is always some PEDMAS quirk to it so ~70% of the people get it wrong, causing yet more comments pointing out how they are wrong and further inflating engagement. Those are worse than the stupid Farmville/Mafia Wars posts that used to horrendously clutter up the platform, at least those are easy to block. Those math things come from all different sources so blocking them isn't effective.
For folks that are out of the loop, the post looks something like “24/4*3: 80% of people get this wrong!” and the arguments in comments are between people who do this the way most computers do (multiplication and division have the same priority and the leftmost one goes first, so you first calculate 24/4 to get 6 then multiply by 3 to get 18) versus the way that the acronym literally says to do it, (multiplication comes before division in the acronym so you first multiply 3x4 to get 12, then divide 24/12=2).
Part of the reason that it generates so much animosity is that we condition people to think of math as always having a right answer, it is the Fount of Objective Truth. The idea that math is sublimely subjective, is indeed an artistic medium, does not seem to be well-appreciated and is often not even acknowledged. This is usually chalked up to the fact that math has “rules,” which is a very strange sentiment because the points in a sports game also follow “rules” of a similar sort but we usually don't regard those as either objective or subjective, they exist in a murky third world where we do not ask those questions...
The poster gains by getting a large amount of interaction with their page, which is certainly a ranking factor for future posts. e.g. SocialMediaCompany will say "This new post by Poster will get higher placement because their previous posts were enjoyed (interacted with) by many people, and therefore Poster must be producing good content."
