Survivorship bias is when the people who survive don't understand why other people failed. We understand why they failed and the most common reason is that most people aren't comfortable making quick decisions where people's lives are at stack. Time of day usually isn't a factor here, but people's confidence in themselves to trust their training and decisions. The other reason is people just can't handle the shear amount of knowledge (rules) required to perform the job. Such as not everyone can become a surgeon due to the education, skill-set and intelligence required not every person can due air traffic control.
