Well, we are all able to predict the future to a certain extent. Common
sense gives us some fairly reasonable power in this domain. If you study
predictive sciences you further develop it. But, although you were kind of
vague, I take it that you meant to predict the future of *humanity - a sort
of a intuitive and innate psycohistory.
This is all theoretically possible but very unlikely. Even if a psycohistory exists (and then it wouldn't be restrained to "sensitive" people - computers would probably do it much better) it wouldn't be enough to predict the future because some individuals have to much power - and no psycohistory is able to predict the behavior of individuals, by definition - and because much of what makes human history depends on developments of technology, and said psycohistory would have to _KNOW_ if things like IA and nanotech (as well as steam and electricity) are possible or attainable, and obviously that isn't in its "field".
And even if you don't take that into account and psycohistory is possible then why should there be an innate version? There isn't much evolutionary pressure for that, and it would have to have developed after society but by then humans were already fairly insensitive to natural selection (not to mention the extremely short time in which evolution would have to act, especially if you consider that psycohistory is much more complex than even intelligence).
And even if an innate psycohistory existed, how would the "sensitives" gather the "initial conditions" of the system? There is fairly strong evidence pointing to a maximum, and fairly low, rate at which humans can absorb data. So, by the time the initial conditions were gathered, assuming the sensitive didn't die by then, they would be grossly out of date and therefore inadequate - as the sensitive would not have gathered a single and concise set of past conditions but a mixture of conditions of past and present).
