I personally don't believe that anybody has the power to see into ones future because if that were the case, wouldn't there be a lot less tragic events in the world due to a clairvoyant's aid?

Also, there is a 1 million dollar prize still up for grabs for somebody who can win a contest that proves they are capable of magic; said prize has been up for grabs since the 1950s, yet if we had clairvoyants, wouldn't one of them have claimed it already?

With that being said, I don't doubt that there are things humans are capable of that defies logic and reason and I also believe that we have yet to scratch the surface of all of the knowledge and secrets in the universe, however, I would need to be shown some demonstrable evidence for something such as clairvoyance in order for me to believe in it.
