I’ve noticed it in myself too. Incredible how people actively avoid 20, 30, 40, 50, 60, 70, 80 as they’re all deemed not random, choosing from 1-100.
And variations containing 7 are very common, given it’s a ‘lucky’ number for many. We’re just all too predictable sometimes.
Scary to think if you combine this logic with password generation. Auth is so incredibly insecure.
