I believe you but you should know you are in the minority here. Part of why TikTok has taken over the social media space is because of how addicting it is compared to the older players.
I can completely understand how it keeps your attention longer than looking at photos of your neighbour's cat like Facebook gives you. It's just the lack of variety that makes addiction hard to fathom. Do others not get bored of seeing the same thing over and over and over?
To avoid seeing the same thing over and over, the most direct form of feedback that works for me is when that content comes up, quickly swipe past it. If you keep swiping, it'll start throwing more random stuff at you to see what sticks. I'm also always tweaking the list of people I follow so that if FYP gets stale, I can just look at their content for a bit.
I have heard that before, and tried it briefly, but it didn't accomplish much in the short time I tried. I can believe if I put a lot more time and effort into it that might change, but the last thing I need is another job. The whole value proposition of trying TikTok was the promise that it would do that work for me.
They're testing features to let you "reset" your algorithm to improve content diversity. But even without that kids spend over 80 minutes a day on TikTok.
TikTok is massively popular but it's not yet the case that not using it puts you in the minority, like Facebook does.
Who's your cohort? If you're in high school, yes it does.
Do you have the stats for that? I recall reading something earlier this year than Insta is still king for teens/young people. I can't find the source though.
According to Pew Research, amongst the 13-17 year old set, YouTube is king, followed by Tiktok
