Why you can't stop scrolling: the science of 'dark flow'
You pick up your phone to do one quick task, and suddenly 20 minutes have flown by without you even noticing. How do apps do that to you? Science journalist Michaeleen Doucleff felt like her phone had superglue on it, holding her on it for hours each day while draining her of time and energy. Turns out, that feeling isn’t accidental. In her new book, Dopamine Kids, Michaeleen describes four features that tech companies add to apps to keep us scrolling for as long as possible. She’s sharing this superglue recipe with Short Wave host Emily Kwong … and explaining how these features can pull people into what scientists call a ‘dark flow’ state.
