I'm just finishing my PhD now, and have generally always been someone that reads the scientific literature and takes things seriously.

But I know so many people that take absolutely 0 care, whether it's now in regards to COVID, to other illnesses, and just constantly risk themselves without understanding the shit they might be facing if it goes wrong, yet it seems nothing happens to them.

What the fuck is going here? Is it cognitive biases by me? I just don't notice they get fucked because they hide it? Is everything wrong in science? What the fuck is happening. I need to understand.
