H. L. Mencken Quotes
The world always makes the assumption that the exposure of an error is identical with the discovery of truth - that error and truth are simply opposite. They are nothing of the sort. What the world turns to, when it has been cured of one error, is usually simply another error, and maybe one worse than the first one.
Mencken, H. L. Prejudices: Third Series. Alfred A. Knopf, 1922.
Science has the interesting characteristic that most failures are successes in the sense that scientific knowledge is gained from the failure even if it only a guide to what not to do in the future. Politics would be well served to adopt this pragmatic approach, but ideology usually prevails in politics and errors tend to be repeated if there are supported by political philosophy or ideology.
A null hypothesis is a statistical scientific term that a researcher assumes and uses to compare other things to. If there are no significant, found differences, the null hypothesis is not rejected. If significant differences are found, then the null hypothesis (yesterday's truth) is then rejected. In science, no one has been right for 400 years since Aristotle. Truth is never eternal. It is continuously subjected to testing and conformation and history has shown that with new instruments, new techniques and new other findings to work from, sooner or later what we think is true today turns out to not quite be so. Often it is not completely wrong, but the old "truth" turns out to be not so in all cases or situations. For example, the mechanics of Isaac Newton was assumed for a few centuries to be true. Then along came Albert Einstein and he showed that Newton was right except when objects were traveling at very high speeds when Relativity explained them. And in less than one century, we realized that Einstein's Relativity explained everything except very small particles which are better explained by Quantum Mechanics. This process of will almost certainly continue.
