Question about the "dopaminergic" aspect of screen time.

The screens themselves aren't the problems as much as what content you're consuming on them.

Porn and social media are designed to be extremely dopaminergic. Eliminating porn and dramatically reducing social media use is a very good start.

You can tell it's less about the screen and more about the content just by doing a simple movie test: what movie engages your eyes and attention more strongly--a slow drama about a failing marriage, or a Michael-Bay-directed action movie where there's a cut every half-second? In both cases you're "looking at a screen."

If you're watching a long-form lecture by Jordan Peterson on YouTube, that's far less dopaminergic than if you're binging dozens of Jordan Peterson clips on YouTube Shorts.

It just depends on what you're giving your attention to ... or in some cases, on what is demanding your attention whether you like it or not.
