You did very well in asking this. You are very clever.

What is the point of being self-aware if the only thing you are aware of is your inadequacies and failures? We need validation in order to keep going.

Because for the longest time, we lived in tribes. If you got thrown out of your tribe, that was essentially a death sentence.

A desire for approval drives social creatures towards pro-social behaviour, which can positively influence the sucessfulness of a species

I don’t actually like validation, recognition, or getting compliments, but I somehow feel slighted when I don’t get them and think I should’ve.

Some good answers, but I also want to point out that this isn’t actually a universal need.

I think that our social nature, and the way most societies and communities work (particularly in countries that subscribe to exceptionalism) makes them prone to developing these feelings, but they very much are not universal and can even be unleaned.

Because we’re a social species that often checks ourselves off of those around us. Sometimes it’s unhealthy, but often it’s an attempt to maintain tribe status and to safeguard against misperception.

People generally need some validation but I think you’re making an inaccurate generalization
