Certainty is the enemy of growth.
In order to progress, scientists (and the rest of us) had to let go of our closely held beliefs and be open to the possibility that those old beliefs weren’t serving us. One of the hallmarks of good science is constantly challenging our prior conclusions — to never truly be “fixed” in any given certainty. To grow, we have to constantly question our beliefs about ourselves, others, and our reality. That is how we evolve.
