I don't wanna say it's a mistake. I think perhaps somewhat oversimplification of how people conceptualize dopamine's role in the brain is even though it's a major important role is for it to be active and released during highly reinforcing experiences like sex, like really good food, like drugs of abuse.

It also can get activated subdivisions of the system during painful stimuli and during aversive stimuli, which again are really important for you to be aware of to say, "Oh my God, that's really bad for me." And so the dopamine system, this reward circuitry and its subcomponents that maybe perhaps signal more salience or aversion in the environment are closely tied to arousal systems and memory systems.
