Humans have a “tendency to prefer the illusion of certainty to the reality of doubt.” [The Wisdom of Crowds by James Suroweicki]
In any situation we quickly become convinced that we are correct. “This is certainly true, I am right.”
We should not be so quick in our judgments of certitude.
There are few things in life that we can be absolutely certain are true. Even scientific “laws” are just theories that may be discarded at any time if countering evidence is found.
Best to act on your present knowledge while doubting what you know.
Best to adopt an attitude of wisdom.
