A Fact Is Not An Opinion

One of the most popular segments on E.S.P.N.’s popular Sports Center is called “Cold Hard Facts,” and it consists of one or more “experts” sitting down and giving his opinions about upcoming sports events — not facts. The confusion here between “facts” and “opinions” is instructive. We seem to have lost sight of a rather important distinction.

While there is nothing we claim to know that should ever be held beyond doubt, as I mentioned in an earlier blog, there is certainly a basic distinction between an opinion — which can be silly or sensible — and a fact which has the weight of evidence and argument behind it. It is a fact that water freezes at 32 degrees fahrenheit. It is a fact that objects fall toward the center of the earth. The most reliable facts are in the hard sciences and in mathematics (though there is some discussion whether a mathematical formula is a fact of simply a tautology). But even when an expert tells us that the Baltimore Ravens will repeat as Super Bowl Champions, that is an opinion.

As mentioned, opinions can be silly — as in “there’s a monster in my closet,” or sensible, as in “unless you are a really good bluffer, don’t raise the bet when holding a pair of twos.” And opinions can differ in degree, some being more likely or more probable than others. But they do not cross over into the territory of fact until the weight of argument and evidence is so heavy it cannot be moved. Thus the opinion that smoking causes cancer became fact once the correlation between the two became very nearly inviolable (there are still exceptions). And the opinion that humans are evolved from more primitive animal species became fact when the weight of evidence became so heavy it could no longer be ignored — except by looking the other way.

One of the big controversies in our schools, especially in the South, is whether “intelligent design” is a fact or an opinion; that is, whether or not it should be taught along with the theory of evolution. But as there is no possible way to disprove intelligent design and there are any number of ways to disprove evolution, the latter can be regarded as fact whereas the former cannot. Intelligent design, the claim that human evolution is guided by a Creator, is a matter of faith. It may have plausibility, but it cannot be proved or, more importantly, disproved. This is where Socratic doubt comes in.

The secret to Socrates’ method was to doubt until we could doubt no longer. At the point where a claim seems to be beyond doubt, we can claim it is true — so far as we know. The key to the Socratic method was questioning and attempting to disprove. That is the key to scientific method as well. Claims become factual when they are testable but they cannot be disproved. If there is no way, in principle, to test a claim it cannot ever rise to the status of fact. Karl Popper said this was the case with Freud’s and Jung’s theories: they cannot be tested and proved or disproved, therefore they cannot be regarded as scientific fact — no matter how useful they might prove to be in explaining human behavior.

We can talk until we are blue in the face about who was the best basketball player ever, or whether the souls of evil persons will suffer eternal punishment, but since no claim we make about the soul or the best basketball player ever could be tested or proved one way or the other, we never get beyond the realm of personal opinion or belief. The claim that the polar ice caps are melting is a fact. The claim that humans are part of the cause of global warming is an opinion, though it is plausible. There are core samples that support the claim on the basis of the amounts of carbon dioxide in the air in the past 150 years — since the Industrial Revolution. And in this case, it would be wise to treat it as fact because even if it turns out to be false, it hasn’t cost us a great deal. And if it turns out to be true, we will have taken steps to solve a serious problem facing our earth.

Distinctions help to clarify our thinking. When they are glossed over, it leads to confusion. That is my opinion, but it seems plausible. That is the most I can say until further review.

  1. In my opinion, this is a great post. Your timing is great. Last night on Bill Maher, he had a professor of physics on the show and they had a similar discussion on the need to make data driven decisions. Well done, BTG
