In the weird way things sometimes go, I posted my thoughts on Tinderbox and The Brain yesterday, and this piece appeared on NPR.

So, in terms of "rewards," dopamine doesn't play a role in "liking" an activity or behavior; but it does mediate desire for an activity or behavior. Which kind of makes sense. I didn't like much of my experience on Twitter, but I did want to do it. And desire is the source of all suffering. (Usual disclaimers apply.)

I don't think this more complete understanding of the role of dopamine seriously alters my "thinking" on how our biology interacts with our technology to shape our behavior.

But I did laugh when I saw the piece!
