The Taboo Dictionary, Item 118. Tonight's entry: "Chronic Subscription Cancellation Inability Syndrome." Tuesday night, 11:30 PM. I open my billing app on the living room sofa. Netflix, ¥1,490/month. It's been deducted again this month. I haven't watched it in six months. I tap "Cancel." A large "Pause" button pops up on the next screen. My finger hesitates. My finger presses "Pause." I tap "OK" to the "Do you want to check again next month?" pop-up. I close the screen, and the moment I return, a strange sense of accomplishment spreads. "That was the right thing to do," I think. But the next month's bill shows ¥1,490 deducted again. The world calls this "subscription poverty," "subscription fatigue," "cancellation refugees," or "auto-renewal hell." But what does that explain? — Why doesn't the finger move even though the brain knows it's "not being used"? Why do we reflexively press "Pause" instead of "Cancel"? Tonight, we'll dissect the three-layered trap from the perspectives of behavioral economics and cognitive bias theory. ■ Seven Studies ・★ Samuelson & Zeckhauser (1988) J Risk and Uncertainty ── Status Quo Bias.
