What this video covers
Loss aversion is the way losing something hurts more than gaining the same thing pleases - roughly twice as much. The maths is identical; the feeling is not, which is why "don't lose this" pulls harder than "get this".
It was the same £5 and the same action both times. Framed as a gain it was easy to shrug off; framed as a loss about to expire, it suddenly felt worth doing now. Nothing changed but the wording around the word "lose" - and that did the work.
