What the Bleep do we Know?

A friend of mine recommended that I check out the film documentary, What the Bleep do we Know? I haven't been brave enough to check it out yet since documentaries are generally about as appealing to me as root canal sans novicane!
However, in the movie, much is made about belief and its power to provoke change. One of the most intriguing portions of the movie dealt with a study performed by a Japanese scientist named Dr. Emoto, who blessed water with various blessings, then took microscopic photographs, and found different formations at a micro level that looked similar to snowflakes. The argument here is that our beliefs do actually impact the world around us, and that if we only believe in something strong enough, we will in fact have the capability of influencing the world.
Is this true? If we believe in something strong enough, does that belief have the power to influence culture? It was my Tae Kwon Do instructor who was fond of saying, "Whether I think I can or whether I think I can't, I'm right." Thoughts?
