Emotion, Attention, Overstimulation: Massive meta-study reveals how TikTok, Shorts, and Reels are rewiring your brain

Short-form video wasn’t supposed to become our generation’s Matrix, yet here we are, scrolling ourselves into a new cognitive baseline. Drawing on Feeds, Feelings and Focus, a meta-analysis of 71 studies and nearly 100,000 people, this piece maps how TikTok, Reels and Shorts quietly retrain the mind. Attention thins, emotions accelerate, adults prove no more resilient than teenagers, autonomy erodes in micro-increments, and identity becomes whatever narrative the algorithm reflects back. No machines, no pods, no cables — just a device we willingly consult. The dreamworld didn’t need to trap us. We walked in, thumb first, without noticing the door.
