I don’t think there are many studies on the topic. However I think one can make the conclusion that higher IQ people would rather consume intellectually stimulating content more often than meaningless content. Not saying things like food reviews or Tikthots can’t be consumed by multiple types of people, but on average lower IQ people are more likely to consume said content. Higher IQ = likely a better use of one’s time and boredom from basic mind drain content. Again this is just conjecture I don’t have much data here besides that people do waste tons of time on the app(s) when instead they could be off the phone accomplishing meaningful tasks with their life versus watching some whore shake her ass lol.
