If it were factually not a good idea to believe facts, then why shouldn't you simply disbelieve that fact? Your argument here is blatantly self-contradictory and demonstrably useless. Facts should be believed because they are - by by definition and in practice - necessary to avoiding failure. Those things that cause failure are factual components of reality. If you don't believe in them, how can you hope to avoid them? Those things that lead to success are factual components of reality. If you don't believe in them, how can you hope to understand them? Etc., ad infinitum for all things.
