Atlas Shrugged
There are some things that do require instant action, as I hinted at in item No 2 in my previous post, and as has been expanded upon correctly by SKS777FLYER. However, I think all three of us are agreed on the need, normally, to take one's time and to act calmly and methodically - as demonstrated rather magnificently by the elderly captain who wound the clock!
My reasons for not normally rushing into action are (1) to guard against taking the wrong initial actions; and (2) to avoid the wrong hypothesis.
This latter point is subtle and important. If something alarming happens suddenly and you fixate on the wrong hypothesis it is almost impossible, when under stess, to re-evaluate the situation and to change your mind. You are then in danger of carrying out a set of actions which may well be the right ones for the false hypothesis but not appropriate for the actual situation.
