We expect simplistic views from simpletons but not from educated professionals. Sadly though, some people do emerge from higher education without a rounded picture of the way other disciplines add value, so they simplistically over-state the role of their own discipline and pay only lip service to others.
New words are needed to describe and counter the influence of such people and their non-specialist followers. Here are a couple to get started with.
Economists are prone to economisticism, the excessive focus on a narrow concept of economics. For me as an economist the most glaring involve tribal demarcations within the discipline, where there is plenty of contrary evidence and reason but it is ignored. Two examples will suffice.
- The extreme reluctance to loosen monetary policy in Europe in the face of serious recessions despite plenty of contrary evidence.
- Whoever designed "light handed regulation" in late 1980s NZ. This was a mad scheme, unique in the world, that allowed natural monopolies (powerline networks etc) far too much lattitude and ended up costing consumers billions of dollars (pdf).
Scientisticism is also a thing. I'm no scientist, just an interested observer and user of science outputs in our farming efforts. However I know enough to recognise scientistic thinkers: people who place excessive reliance on science. Mainstream agronomy offers lots of examples but I've flogged that enough lately, so let's return to the skeptics.
- Alternative health remedies are scorned by skeptics to the point where they reckon one's own personal experiences should not be quoted to friends. To be fair, the NZ group is mostly into fighting the really fringe stuff which is fine by me. But they also have a broader antagonism toward traditional/natural/folk medicines and when they start down this track they sound like doctors that are thoroughly versed in pharmacology but not much else.
- They're really keen on GMOs, I think because they're seen as scientific outputs. That would be fine if they didn't also ignore, downplay and/or ridicule contrary views that derive from other disciplines. But they do. Consumer views, which are relevant to the economics of GMOs, are written off as ignorance, contrary science is attacked, and statistical risk assessments are criticised for lacking empirics.
