Reaction videos are a new genre of entertainment Gen Z and Millennials can’t get enough of. YouTube pioneered reaction videos—and now they’ve become a part of young people’s everyday lives. With features like TikTok’s Stitch and Duet, users are constantly being exposed to people’s reactions to other creators’ content. Some pages are even dedicated to doing just that with supposed experts commenting on an array of content, like choreographers evaluating dance moves, vocal coaches noticing someone’s range, dermatologists judging skincare routines, or history buffs correcting conspiracy theories. Scientists have proved there’s evidence that watching reaction videos satisfies the parts of our brains that seek connection, “when we see someone experience pain or disgust or joy, we ‘feel’ it, sort of. That would make watching people react an exercise in empathy.” YPulse’s Clicking on Commmunity trend report data shows 29% of Gen Z and Millennials stay up-to-date with their online communities through comments on videos and other creator content.
