My theory about celebrity culture is that it is deliberately attempting to replace normal human interactions ('normal' being something like pre-industrial village society, where most people knew the same ~100 people or so for much of their lives) with a media-constructed social circle of 'celebrity influencers' of similar size.

For this to work, one has to consume a lot of entertainment media, which likely uses a limited vocabulary and very little if any symbolic logic (the intelligence tests in this study used these two characteristics).

For maximum dystopian creepiness, imagine a 'personalized celebrity-based AI chatbot community' for such people... programmed with the correct opinions on all matters.
