Uncertainty leads to poor choices. People seek certainty at the cost of their well-being. We have been "certain" about such horrors as eugenics and such trivialities as not swimming for an hour after eating.

We've had brutal endings to cults, in Waco, in Jonestown, because conmen had convinced followers that they had certainty. We have polarization today because opposing politics or values cause adherent to be "certain" about their position and hold those who disagree as inferior.

There are people taking invalid behavioral tests to dismiss others as having weak or defective profiles, and they are certain that they are superior to them. I remember when so many people had their feet burned trodding over hot coals that more EMTs had to be called. I guess their motivation wasn't sufficient—they were uncertain.

BOTH science and religion try to create certainty around the mysteries of the universe, as if we could understand the unfathomable. (What do we mean there was "nothing" and then there was "something" which then "exploded"...??)

In this age we need to live with and thrive on uncertainty. Solid companies such as GE suddenly crumble. Upsets in sports abound. We have gone from "global warming" to "climate change" to try to correct prior uncertainties.

Can you be "certain" that your kids aren't using drugs or that your elected officials aren't stealing? I'm not calling for continual cynicism, but I am suggesting we have to live with uncertainty and be resilient and agile enough to deal with the failure of the "certain."

These two astronauts who went to the space station for a week and nearly stayed for a lifetime are good examples of dealing with uncertainty. Of course, they have "the right stuff."
