About 70% of people in a disaster do it
They even tend to quiet and calm the 10-15% of people who freak out.
The downside of the bias is the fact that they tend to retard the progress of the 10-15% of people who act appropriately.
Those are the three important things in this article. Be alert, think about things before they might happen, and dont let the 85% of people who cant figure it out bother you. That said:
BUFFALO JUMP!!!
KILL BOX!!!!
PANDEMIC!!!!
GLOBAL WARMING!!!!
EXTINCTION LEVEL EVENT!!!!!!
IOWs "freaking out" is the appropriate reaction. I think they teach that to the SEALs in BUD/S.
