Hmmm. . I'd have to disagree. We all chose what we will believe. If what we believe kills us, we still made the choice to believe it. (Example: The homocide bombers).
But you do touch on an interesting question, viz., the degree to which our beliefs are rationally chosen. While you might find it odd, I tend to think that lots and lots of our beliefs are not rationally chosen. That was my point when I referred to the influence of our brain operating systems. Those systems (there are several, as you probably know) provide for a wide variety of beliefs about ourselves and the world. Most of those beliefs are not so much chosen as discovered (they're features of the operating system...and sometimes they're bugs!).
Alfred North Whitehead wrote that "civilization advances by extending the number of important operations which we can perform without thinking of them." While I hesitate to augment the thought of such a luminous intellect, I would add that it's important to ensure that the operations are rationally based before consigning them to the care of the unconscious.
