It is easy to underestimate the pucker factor, the fear factor.
NO ONE does better under pressure. One starts thinking of the consequences. These can be quite severe.
It is easy to panic and lose control of one’s emotions. Then, one just wants to get out of there. This is prime time to make mistakes. And it is understandable.
Everyone is stupid under pressure. No one does well their first time. These are eternal truths that even hold for police.
My favorite story about pressure is of a NYPD police officer. He was 6 ft from a suspect. He fires his service weapon 23 times into a crowd. He hit several bystanders but not the suspect. 6 feet away and he can’t hit a guy – that’s pressure.
