“There is nothing to fear but fear itself.” But fear is rational when there is something to fear. Fear leads to a careful consideration of options and alternatives to come up with those that will lead to the best chance of survival for the individual and for the group as a whole.
It is panic that is counterproductive. Panic leads to grabbing upon the first lifeboat that comes along and overturning it in your haste to get out of the water. Panic leads to disaster.
