You’ve heard that social media is screwing with your brain. Maybe you even read about it on social media. (So meta; so messed up.) The neurochemical culprit, dopamine, spikes when you like and get liked, share and are shared. You’ve probably also heard scientists compare the affliction to drug or alcohol addiction. That’s fair. The same part of the brain lights up. Scroll, scroll, scroll. It’s a phenomenon now so pervasive that it’s got a name: zombie scrolling syndrome.
