Progress cannot happen amongst people who are unwilling to accept they could be wrong. The scientific method is based on the truth that ideas, hypothesis, can be wrong and hence requires proof of hypothesis that is peer reviewed and consensed as being right or most likely right. Proofs are not only facts but also consensed arguments of what is most likely right. Built in to science is acceptance that what may be considered a proven correct hypothesis today could be proven incorrect hypothesis tomorrow and that is considered to be progress.
