It's a lot more variable than that.

Even the same people will react differently to different crises, and even to the same crisis at different times. There are times when a crisis has forced me to focus, and there are times when it has not.

Similar to an earlier post, I know someone who was in court for a workplace comp case when one of the lawyers had a major heart attack. Surprisingly even though there was at least one doctor and one nurse in the courtroom for other cases, it was this guy with just fundamental first aid training that started CPR, the others were too stunned to act quickly.
