Yes, but also let's cut people some slack: most people on either side of IQ 100 are spending all their energy at work, and between the job, commute, preparing food, spending time with kids, etc. they only have enough energy to crawl into bed and start the grind again the next day. With that in mind, the popularity of low-effort, high-dopamine entertainment doesn't necessarily imply that most people are simple-minded and just like this - the alternative hypothesis is that they just don't have time and energy for any more complex, richer ways of spending their time.
