For reasons too personal to put here, I've been pretty depressed and dysfunctional lately and I've unintentionally discovered the experience of doomscrolling. The output of the instagram algorithm is absolutely terrifying. It has the perfect metrics (swipe time, profile browsing, etc etc) to prey on every impulse inside of you and to send you the perfect cocktail of content to feed those impulses. Fear, doubts, wants, etc. etc. are all inputs to the algorithm and the output is content that makes you feel those things more.
I have to wonder if this type of media is similar to magazines on steroids, or other pulp media of the bygone era. No one here makes this comparison so maybe I'm off base but I do often if I'm scrolling through the worst possible version of a home produced checkout-aisle magazine.
EDIT:
I appreciate the comments that make this personal and are trying to help, but my instagram problem will be fixed when I manage to fix my real life problems... a much bigger task. My point is to highlight that the algorithm can suck anyone in, not just teen girls. They just happen to be the most vulnerable.
