scientism

Scientism is not just being very Scientific; it is the mis-application of Science.  It's pretty much the tendency to use Science-like thinking for everything. This can be a problem.  For example, there's really no reason to believe that methods that work for matter also work for intangible, transcendent, or spiritual things.

The problem for the Scientism-ist (sorry about the word) is dismissively convincing themselves that most of the civilised people that ever lived, and most they meet, are either morons or insane.
