" One danger here, of course, is that once we insist or pretend that we know the answer based on premature or incomplete evidence (even if we’re pushed against our will to take such stands), we’re likely to continue to insist we’re right, even when evidence accumulates to the contrary. This is a risk in any human endeavor. When Francis Bacon pioneered the scientific method almost four hundred years ago, he was hoping to create a methodology of critical or rational thinking that would minimize this all-too-human characteristic of avoiding evidence that disagrees with any preconceptions we might have formed.*1 Without rigorous tests, as many as necessary, beliefs and preconceptions will persevere because it’s always easier to believe that a single test has been flawed, or even a few of them, than it is to accept that our belief had been incorrect. The scientific method protects against this tendency; it does not eradicate it. "
