What this video covers
The spotlight effect is our tendency to think others notice us - our mistakes, our appearance, our small slip-ups - more than they actually do. Because we’re the centre of our own attention, we overestimate how much of a spotlight is really on us, while most people are too busy with their own concerns to notice.
You guessed a fairly high number noticed the flaw - and the real figure was much lower, because everyone else was absorbed in their own thing. That gap is the spotlight effect. It's worth remembering twice over: your users feel it too (so soften visible mistakes), and you feel it about your own work (so don't burn hours on a blemish nobody will see).
