Logical Fallacies, Formal and Informal
The Autonomist ^ | March, 2003 | Reginald Firehammer

Posted on 04/06/2003 10:12:13 AM PDT by Hank Kerchief

Lately we have seen the notion of falsifiability represented as a fallacy. This is itself, a fallacy.

The concept of falsifiability is a greatly misunderstood but legitimate part of the scientific method (a rigorous application of reason to evidence). Consider this statement made as an objection to falsifiability, "Falsifiability can be a valuable intellectual tool: it can help you to disprove ideas which are incorrect. But it does not enable you to prove ideas which are correct." In fact, that is exactly what "falsifiability" does do, and without it, no scientific hypothesis can be proven.

In science, a proposed hypothesis is not considered valid if there is no experiment that can be performed that would, if the hypothesis is incorrect, fail. If such an experiment can be performed, and it "fails to fail," it is proof (or at least very good evidence) the hypothesis is correct.

No doubt the prejudice against this very useful objective method lies in the name, "falsifiability." It does not mean the scientist must attempt to prove a hypothesis false, but the very opposite. "Falsifiability," is the method by which a hypothesis may be proven true. It also does not mean that a hypothesis must be assumed correct until it is falsified.

The idea of falsifiability protects the field of science from being obliged to entertain as, "possible," any wild hypothesis on no other basis than it cannot be disproved. If a hypothesis is correct, there will always be a test or experiment that it would fail, if it is incorrect, which when performed proves the hypothesis correct by not failing (or incorrect by failing).

If no test can be devised for testing a hypothesis, it means the hypothesis has no consequence, that nothing happens or doesn't happen because of it and nothing depends on it being right. If this were not true, whatever depended on the hypothesis could be tested. There is absolutely no reason to entertain a notion that has neither purpose or consequence.

"But why not perform experiments to verify rather than falsify?" In fact, all experiments performed to test a hypothesis are attempts to verify it. If such a test could "pass" even if the hypothesis were incorrect, passing the test would prove nothing. Passing a test is only, "proof," if passing is only possible when the hypothesis is true, which means the test must fail (the hypothesis will be falsified) when the hypothesis is untrue. A test which cannot falsify a hypothesis, if it is incorrect, cannot prove it, if it is correct.

To say a hypothesis is not falsifiable means that it cannot be proved (or disproved), and, therefore, is unacceptable as a scientific theory.

It is very unfortunate that this concept is misunderstood by many who are otherwise quite rational and objective. The principle not only applies to science, but almost all complex or abstract concepts. The attempt to verify any conjecture by means of a method that cannot discriminate between those conjectures which are true and those which are false can never discover the truth. Only a method which distinctly demonstrates a conjecture is false, if it is, can verify those conjectures that are true.

The concept of falsifiability sweeps away mountains of irrational rubbish masquerading as science, philosophy, ideology, and religion. One question that must be asked about any doubtful proposition or conjecture is, "how can this be disproved if it is false?" If there is no way to test if the proposition is false, there are no rational grounds whatsoever for assuming the proposition to be true.

There is no immediate consequence on earth for rejecting it but there is later.

How do you know that?

When you are limited to the optical part of the spectrum ...

But, we are not. If we were, we would not know the visusal part of the spectrum is not the entire spectrum. The senses are not a limit to knowledge, they are the only means to knowledge. The senses are not knowledge, they are awareness (and the only awareness we have) of reality. Knowledge is what we come to understand about that reality we are conscious of.

Not by science or reason. I guess that only leaves faith.

Then why all the angst over something that is of no consequence to it?

So you just believe what you believe, with no evidence that it is true, and for no reason whatsoever. How is that any different from what any religious, superstitious, or psychotic person believes? They have exactly the same basis for their belief as you have for yours, nothing at all.

(By the way, do you think science is unable to discover the truth of anything? This article only pertains to what science can discover, and how to prove that, and nothing else. Since you believe faith and science belong to entirely different realms, your comments are irrelavent to the subject of this post. I think that is what tacticalogic has been trying to convey as well. He can correct me if I'm wrong.)

Who has angst and who said there is no consequence?

You apparently do, and if your faith is independent of logic, how can logic be of any consequence to it?
