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.

Does Darwinism explain anything?

Dr. Cornelius Hunter answers the question here. (H/T ECM)

Here’s the criterion specified by naturalists to make an explanation scientific:

…in order to qualify as legitimate science a theory must distinguish between different outcomes. Naturalism is needed because otherwise each outcome is equally probable and the theory is not true science.

Deciding what does and does not qualify as legitimate science is notoriously difficult. There seem to be exceptions to every rule. But perhaps Felsenstein’s criterion is reasonable. Shouldn’t a scientific theory say at least something about the probabilities of what we might observe in the data?

Does Darwinism satisfy the criterion? Hunter argues that it does not.

Whatever we find in biology, evolutionists say it must have evolved. Their predictions and expectations are often falsified and they have to patch their theory repeatedly. And there is no distinction between a new, fantastic design and a repeated design–both are equiprobable under evolution.

If a new, fantastic design appears such as the trilobite eye, then evolutionists ascribe it to natural selection. If similar designs are found in different species, then it is ascribed to common descent. If later cousin species are found to lack the design, then common descent can be dropped as an explanation and the design can be said to have evolved independently. The evolutionary explanation is extremely flexible.

If distinguishing between outcomes is the hallmark of true science, then evolution is the theory that doesn’t qualify.
