How accurate is the conventional wisdom about dopamine?

“Dopamine” has entered cultural conversations as roughly equivalent to “the feel-good brain chemical.” People talk about “dopamine hits” and “dopamine fasts” and “low dopamine.” In a recent conversation a family member talked about starting the day on his phone and scrolling feeds “because I’ve gotta get my dopamine up before work.”

There’s a seemingly widespread understanding that dopamine makes us feel good and that it can be used against us to make us do things we don’t necessarily like (like endlessly scroll feeds).

Is any of this accurate to how dopamine actually works in our brains? It feels like an oversimplification to me, but I don’t actually know.

It also seems odd to me that there’s so much focus on dopamine but not, say, oxytocin or serotonin (unless you’re a Billie Eilish or Girl in Red fan, respectively).

Is our lay understanding of “dopamine” efficient shorthand or pseudoscientific sleight of hand?
