Yes. philosophical studies can help one be more aware of one's thinking style (many of us are mentally lazy!) much like a basic understanding of psychology (personality profiles, cognitive styles, etc...). We are the result of our environmental programming (some good, some bad in most cases) and our inherited genetics.
Thinking requires work just like athletic activities require sweat! Don't be put off by intellectuals who delight in engaging in pissing contests ("nerds" can be just as competitive as "jocks") and ignoring real world experience. The key is balance (as always).
