It is possible, but I wouldn't put too much confidence in conclusions I've arrived at through application of the Razor on the field I know little about.

An interesting concept to that effect is that of "epistemic learned helplessness"

Basically, if you're not an expert in some field, then for any given argument, arguments of either side can be made to sound equally convincing to you, so - unless you have time to become an expert in every domain you encounter - your best bet is to accept the general scientific consensus on the topic.

(If anything, Occam's Razor is very useful to determine who is arguing for the generic scientific consensus, and who is arguing out of political reasons, or fear driven by ignorance.)
