This Sunday, former Google product philosopher Tristan Harris will join Anderson Cooper on 60 Minutes to discuss the horrifying reality of our smartphone addiction: It’s by design.

Every time we get a “like” on Facebook or Instagram, it’s like playing a slot machine, Harris explains in the teaser for the episode. Getting so much gratification so quickly keeps us hooked, says Harris, who has written a viral essay and given a Ted Talk with a million views on the topic. Companies want us to scroll forever because “that’s how they make their money,” he says.
