Overcoming dogmatism in science

One more post from 18 months ago:

That we build theories by testing hypotheses and rejecting them if proved wrong by experiential evidence. And not just hypotheses. Prevailing theories are also constantly open to potential falsification, testing against new evidence and changing to incorporate new findings.
