That's widely accepted as part of personality theory. The idea is that you have some "base setting," not that you will literally try anything (or refuse to try anything). It should also be noted that personality is one aspect of your psychology. It doesn't absolutely determine how you will behave under a given set of circumstances. Example: you might be very open to experience, but as a child you were bit by a dog. Next time you see a dog, your experience-based fear could easily overwhelm your natural curiosity.
