Jay Richards explains when you should doubt “scientific consensus”

Jay Richards writing in The American, a publication of the American Enterprise Institute. (H/T Evolution News via Apologetics 315)

This short article summarizes 10 things to look for that hint that “scientific consensus” as a substitute for arguments and evidence.

Excerpt:

How is the ordinary citizen to distinguish, as Andrew Coyne puts it, “between genuine authority and mere received wisdom? Conversely, how do we tell crankish imperviousness to evidence from legitimate skepticism?” Are we obligated to trust whatever we’re told is based on a scientific consensus unless we can study the science ourselves? When can you doubt a consensus? When should you doubt it?

Your best bet is to look at the process that produced, maintains, and communicates the ostensible consensus. I don’t know of any exhaustive list of signs of suspicion, but, using climate change as a test study, I propose this checklist as a rough-and-ready list of signs for when to consider doubting a scientific “consensus,” whatever the subject. One of these signs may be enough to give pause. If they start to pile up, then it’s wise to be suspicious.

Here are the 10 points he discusses:

  • Bundling well-evidenced claims together with speculative claims
  • The use of ad hominem attacks against dissenters
  • The use of coercion to force scientists to join the consensus
  • Publishing and peer review that is cliquish
  • Unwarranted exclusion of dissenters from peer-reviewed literature
  • Misrepresentation of peer-reviewed literature
  • A rush to declare a consensus before it even exists
  • When the subject matter is not easily testable (e.g. – simulations)
  • When defenders resort to phrases like “Scientists say…”
  • When science is used to push for dramatic policies
  • When journalists are not reporting the issue objectively
  • When supports appeal to scientific consensus instead of arguments

One can easily see how this list applies not only to global warming alarmism, but to Darwinism as well.

MUST-READ: What’s the difference between science and scientism?

Here’s an article by Edward Feser at Public Discourse. (H/T via ECM)

What is scientism?

Scientism is the view that all real knowledge is scientific knowledge—that there is no rational, objective form of inquiry that is not a branch of science. There is at least a whiff of scientism in the thinking of those who dismiss ethical objections to cloning or embryonic stem cell research as inherently “anti-science.” There is considerably more than a whiff of it in the work of New Atheist writers like Richard Dawkins and Christopher Hitchens, who allege that because religion has no scientific foundation (or so they claim) it “therefore” has no rational foundation at all.

What’s wrong with scientism?

Despite its adherents’ pose of rationality, scientism has a serious problem: it is either self-refuting or trivial. Take the first horn of this dilemma. The claim that scientism is true is not itself a scientific claim, not something that can be established using scientific methods. Indeed, that science is even a rational form of inquiry (let alone the only rational form of inquiry) is not something that can be established scientifically. For scientific inquiry itself rests on a number of philosophical assumptions: that there is an objective world external to the minds of scientists; that this world is governed by causal regularities; that the human intellect can uncover and accurately describe these regularities; and so forth. Since science presupposes these things, it cannot attempt to justify them without arguing in a circle. And if it cannot even establish that it is a reliable form of inquiry, it can hardly establish that it is the only reliable form. Both tasks would require “getting outside” science altogether and discovering from that extra-scientific vantage point that science conveys an accurate picture of reality—and in the case of scientism, that only science does so.

What else is wrong with scientism?

The irony is that the very practice of science itself, which involves the formulation of hypotheses, the weighing of evidence, the invention of technical concepts and vocabularies, the construction of chains of reasoning, and so forth—all mental activities saturated with meaning and purpose—falls on the “subjective,” “manifest image” side of scientism’s divide rather than the “objective,” “scientific image” side. Human thought and action, including the thoughts and actions of scientists, is of its nature irreducible to the meaningless, purposeless motions of particles and the like. Some thinkers committed to scientism realize this, but conclude that the lesson to draw is not that scientism is mistaken, but that human thought and action are themselves fictions. According to this radical position—known as “eliminative materialism” since it entails eliminating the very concept of the mind altogether instead of trying to reduce mind to matter—what is true of human beings is only what can be put in the technical jargon of physics, chemistry, neuroscience and the like. There is no such thing as “thinking,” “believing,” “desiring,” “meaning,” etc.; there is only the firing of neurons, the secretion of hormones, the twitching of muscles, and other such physiological events.

Scientism can’t even ground our own experience of 1st-person consciousness.

What is self-refutation and what are some examples of self-refutation?

Why, self-refutation is the most wonderful thing in the world, next to irony.

Look at this post from Thinking Matters New Zealand.

First, they define what self-refutation is:

In his Introduction to Logic, Harry Gensler defines a self-refuting statement as “[A] statement that makes negative claims so sweeping that it ends up denying itself.” [1] In other words, it results when an argument or position is undercut by its own criteria  (An example of this would be saying, “I cannot speak a word of English” in English).

Then they have a list of examples of self-refutation. Here are some:

  1. Truth does not exist (Is that a true statement?)
  2. Nothing is absolute (Is that absolutely true?)
  3. I do not exist (You must exist to deny that you exist)
  4. Science is the only way to know (Can you scientifically prove that?)
  5. Only what can be perceived by the five senses exists (Can you prove that by the five senses?)

Go here to read the rest.

I work in the software engineering industry, so we have a lot of nerds running around who believe all kinds of crazy things that are self-refuting. There is a lot of skepticism of the laws of logic and analytical philosophy. A self-refuting statement that I hear a lot is: “Don’t judge me, because it’s wrong to judge other people”. And I just ask them: “Well if it’s wrong to judge other people, then why are you judging me?”. (Actually, I noticed that MandM has a post up about judging right now!)

I wonder if my regular readers have ever heard any self-refuting statements? If you know any more, leave it in the comments.

On another topic, it turns out that the author of this post on self-refutation blogs at Rational Thoughts. I added their blog to the blog roll. Check them out.
