Denial in the face of incontrovertible evidence undermines trust to an extent incompatible with working in any serious organisation.

I’m Indian. I absolutely loathe this part of Indian culture. My uncle was once eating a pizza like a naan (ripping pieces off straight from the box) and I called him out on it, and he said he wasn’t doing anything like that…while holding a piece of naan and the pizza looking like rats had a party with it.

It happens basically constantly, I have never heard my family admit to a mistake unless violently confronted by someone with authority.

Leads to all sorts of issues and societal breakdowns, like police beating people up before even trying to communicate.
