Strange Phobia: Fear of Assertions

I wouldn't put this in the crippling phobia category at all, but it's something I'm reluctant to do; have a small jolt of fear over. But, I possess what could be a superstition: the idea that the more I assert something the more it starts to become my actual belief and I start to feel that way. As in, if I said there's no hope (which I don't necessarily believe) I'll start to seal my fate as such. While I'm sure this is fundamentally true, I take the belief to the extreme I think (but I'm not sure). I have this - perhaps - irrational belief that merely saying it once or twice is enough to plant the seed in my mind, but something tells me it's not that simple. Because CLEARLY people say things and not actually mean them. I know the mind's complex.

Anyone know of any research or information that would further clear this up? I'll elaborate if this doesn't make sense. I'm a little reluctant to post on here because I know people are likely to respond with 'yes, we tend to believe what we assert.' I realize this, but really I'm wondering just HOW MUCH of this asserting it takes for us to start to become suggestible to our own assertion?

Hello OblivionIsAtHand: I'm sorry I do not have the information you seek. But I saw that no one had replied to your post. So I thought I would. Although I can't be of help with regard to the type of information you're seeking, in the category of the mind being complex, one book I have read that I found to be most interesting was: Subliminal- How Your Unconscious Mind Rules Your Behavior by Leonard Mlodinow. The book discusses findings from recent research using fMRI technology. Perhaps this book, or something similar, may be helpful to you.

Thanks, I'll check this out.
