There is sort of a 2-faced nature here. Scienitsts themselves should be maintaining intense skepticism over even the most fundamental beleifs of their field. Here is the "science as a process" that is constantly changing.

However, science also plays a role in public life, where it might make a lot more sense to appeal to the authority and the track record of science. Here is the "science as a set of truths".

Separating the two is difficult though. Some scientists will inevitably become dogmatic about theories in their own field, whereas some in the public will take advantage of internal scientific debates to cast doubt on the whole thing.
