I can see a lot of coherence in viewing right-wing policy in terms of psychological security.
For starters, that is what conservatism is, endorsing traditional values and ways - never mind how traditional they really are, public perception matters of course, not reality - and traditional by definition means the source of psychological security.
Additionally, and perfectly in line with emphasizing traditions, the right likes to endorse simple philosophies. Be it in form of a simple tax system, or be it "let the market fix it!, be it a "Law and Order"-attitude. Simplicity is also a source of security, as it removes uncertainty and gives one the impression of predictability and hence control.
Naturally, that doesn't mean that one has to be stupid to support the political right wing or that one has to be smart if one doesn't. Those are just the broad psychological forces at work shaping the masses. That does mean also the individual is shaped, sure, but here things get way too complex to make any meaningful generalizations - so don't feel hurt OT-right wingers.
