Human beings thrive on certainty and predictability. That’s
not quite true – we don’t really thrive on it – we just crave it. In fact,
science has shown that using similar physiological pathways and feedback loops,
the human brain’s desire for certainty is right up there with food, sex and
other primal urges.
Just as these latter cravings get us into trouble, the
former can as well. We often pass up or neglect what’s possible because we are
hanging on to what is predictable. Even if the predictable is harmful or
destructive, we choose it because it’s what we know. As the saying goes,
“Better the devil that you know than the devil that you don’t.”
Furthermore, we don’t want to be surprised by what lies
ahead so we try to predict and model the future, borrowing trouble and feeling
stress from circumstances that have not yet, and may never, materialize. We
fear crossing bridges that may not even be on our path.
And because humans overvalue certainty, we often pay too
high a price to avoid uncertainty. We give up not only possibilities and
opportunities, we also diminish ourselves for the pretense of control over our
circumstances.
If you aren’t careful, you may find yourself trading away
freedom and fulfillment for certainty.
