なぜ"ドパガキ"は、自分が「中毒患者」だと気づけないのか【脳科学×行動デザイン学】

"What I created steals approximately 200,000 years of human life every day," confessed the young designer who invented infinite scrolling in a BBC studio. In 2025, TikTok will be opened 360 times per user per month. On average, this means the screen lights up on your palm about once every 80 minutes during waking hours. 3.6 billion people open the Meta app daily, more than 40% of the world's population. The Japanese smartphone game market is worth 1.4 trillion yen annually, the majority of which is generated from gacha (loot box) mechanics. These devices were designed by only a very small number of people. And many of them have already deleted them from their own phones. Why did only the designers realize this first? Why can't we let go of these devices? Looking at the problem from three perspectives—behavioral design, neuroscience, and industrial history—the true nature of modern addiction lies in one place. I've been thinking a lot about the true nature of this structure that "confines all of humanity equally within an unconscious dependency." ---------------------------- ▼Timestamps 00:00 - Prologue: A device from Stanford that steals 200,000 years of life 02:30 - Chapter 1: The designers who ran away 06:08 - Chapter 2: Three areas of the brain develop into something completely different in three years 10:20 - Chapter 3: From gunboats to algorithms—the same storyline for 200 years 14:07 - Chapter 4: The grown-up kid—what a 14 trillion yen industry has completed 17:31 - Epilogue: Unconscious addiction traps all of humanity equally ---------------------------- ▼References and Data Sources [1] Center for Humane Technology / Aza Raskin (2013 Infinite Scroll inventor / appeared on BBC Panorama 2018) "Infinite Scroll wastes about 200,000 person-years of time per day."
