What this video covers
The Barnum-Forer effect is our tendency to accept vague, general statements as surprisingly accurate self-portraits. Phrases like 'you crave approval but are harshly self-critical' feel personal because we supply our own context, noticing the matches while ignoring the misses.
The reading felt personal - maybe even spot-on - didn't it? Then you saw everyone got the exact same words. That's the Barnum-Forer effect: vague, flattering statements feel tailor-made because you supplied the specifics and counted the hits. It's why "personalised" results can dazzle with no real personalisation behind them - which is exactly why it pays to make sure yours is the genuine article.
