Should We Know Our Future?

There are several tools of divination many of which have a reputation of success. Some of the interpretations are so vague as to make any occurrence appear foretold but there are those who can, by way of intuition and other skills, be quite accurate.

If someone is told their future and believes it, isn't this the same as cognitive psychology?? If I am told I will meet a tall dark stranger will I not be looking for one?? What is the difference between making the future happen and foretelling it?
