Andrew Solomon writes for The New Yorker:
Social media acts on the same neurological pleasure circuitry as is involved in addiction to nicotine, alcohol, or cocaine. Predictable rewards do not trigger this system nearly as effectively as unpredictable ones; slot-machine manufacturers know this, and so do social-media companies. “Teens are insatiable when it comes to ‘feel good’ dopamine effects,” a Meta document cited in the attorneys general’s complaint noted. Instagram “has a pretty good hold on the serendipitous aspect of discovery…. Every time one of our teen users finds something unexpected their brains deliver them a dopamine hit.” Judith Edersheim, a co-director of the Center for Law, Brain & Behavior, at Harvard, likens the effect to putting children in a twenty-four-hour casino and giving them chocolate-flavored bourbon. “The relentlessness, the intrusion, it’s all very intentional,” she told me. “No other addictive device has ever been so pervasive.”
Social-media platforms harness our innate tendency to compare ourselves with others. Publication of the number of likes, views, and followers a user garners has made social-media platforms arenas for competition. Appearance-enhancing filters may make viewers feel inadequate, and even teen-agers who use them may not register that others are doing the same. Leah Somerville, who runs the Affective Neuroscience and Development Lab, at Harvard, has demonstrated that a thirteen-year-old is likelier to take extreme risks to obtain peer approval than a twenty-six-year-old, in part because the limbic system of the adolescent brain is more activated, the prefrontal cortex is less developed, and communication between the two areas is weaker.
A heartbreaking, frightening read for parents. Being a father of four kids, I live in fear everyday about children digital addictions.
