Most of the time, the best response to a crisis is collect information before committing to action. Most of the time.

That few seconds or minutes of evaluating the threat can prevent impulsive, but deadly incorrect responses.

But be smart about it. When the fire alarm goes off, don't gawk around and ask others, "Is that for real?" Just get up an move to an exit.

Train yourself and family like the military - immediate action drills to immediate threats, (like near ambushes). Know what to do in the event of a kitchen fire, home intruder, tornado, etc. and teach yourself to collect information in less urgent situations.
