We live in the age of copy and paste. Any number of answers are available to us with the click of a button. We can now go through life without having to reason anything out.
I admire scientists like Niels Bohr and Richard Feynman who were humble enough to realize that the answers are not simple. Feynman warned that anyone who claims to understand quantum physics really really doesn't understand quantum physics. Bohr said that science is an abstract language, like poetry, a descriptor and not the thing itself. The great evolutionary biologist Stephen J Gould warned us of a dogmatic scientific priesthood and defensive scientific orthodoxy.
A great metaphor is the Piltdown Man. Evolutionary biologists long held to Darwin's belief that evolution was a steady and gradual process. The Piltdown Man confirmed their belief by providing a missing link example. Confirmation bias blinded the scientific world. It took 40 years for someone to realize that an ape jaw had been attached to a human skull. It was all a hoax.

New discoveries advance our scientific understanding. However, occasionally we realize that we've forced a jigsaw puzzle piece into place (corrupting the pieces around it). More often than not it's the discovery that the scientific majority is wrong that advances our understanding and allows us to move forward.
