Wise decision making requires a cool and calm frame of mind. And yes, it does require a great deal of time and much information about the issue on which the decision is to be made. After, brainstorming the possible courses of action and the resultant consequences, the decision that is made is considered to be made well.
However, not all circumstances offer the luxury of time and a composed mind to the decision-maker. There are certain decisions which need to be taken at the spur of the moment. Certain other decisions need to be taken within a narrow deadline. Yet, the consequences of such decisions are long-lasting.
Think of a man whose wife is in the Operation Theatre, about to deliver their baby. As he is waiting with much expectation to hear the cries of a new-born, he sees the doctor rush towards him telling that he has to choose between the mother and the baby and that both cannot be saved. What decision is the man going to take? He cannot afford to wait till he gathers his own emotions. He has to take a decision under pressure.
When the Nazis under Hitler went on capturing territory after territory, there were a few noble souls who decided to give shelter to the Jews even at the cost of being discovered and sent to the gas chamber. That was a risky but brave decision taken under extreme conditions.
When the captain and the crew of the great ship Titanic realized that the ship was about to sink, they had to take the quick but courageous decision of laying down their own lives so as to save the lives of those on board.
Quick decision making requires an all time alertness, readiness to respond and preparedness to face the consequences. One quick decision can make or mar our own lives and the lives of many around.
