Define "correct", then we may be able to have a meaningful discussion.

Edit: After re-reading the OP, we will need to agree on definitions for both "correct" and "advantagous".

If I define "advantagous" as "that which is conductive to my goals" and "correct" as "the most accurate depiction of reality" then it follows that the more correct I am, the better I can achieve my goals.

As I said, without agreeing upon a defition of advantage, we can't have much of a debate. Certain incorrect views may very well give a person an advantage in being happy, reproducing, any number of things that humans tend to value.
