It’s an algorithm. You keep watching, clicking, and commenting so it feeds you more of the same. Most people only comment when they are mad and feel like they have to say something! and so the only engagement is rage bait and politics.
Do you ACTUALLY want to fix it or just complain?
Even if you don’t click like or comment it still records how many seconds of each video you watch, even pausing for 2-3 seconds on a video is enough for it to think you are interested. If you quickly swipe up every time it looks politics related (or even more effective: close the app) the algorithm will learn not to show you that.
If you REALLY want to fix it you have to do a weekly then monthly recalibration. It’s easy: just search for the topics you actually WANT to see, click like on each one and also comment, do this for about 15 minutes a week to fix the algorithm, then once a month for maintenance.
Example: I like new indie music artists and ceramic art and cute bird videos. So every week I purposefully search for things like “new song” “indie music” and “pottery” “glaze results” “wheel throwing” and “funny bird” “casques” “parrots” bird training” “cute birds” etc and for each topic I scroll thru about 20-30 videos and like and comment on each one. The algorithm learns that’s what I like and the next time I’m on the fyp it’s all art and cute birds.
