Trust Experts, But Verify

I'm seeing more along the lines of whatever-happened-to-trusting-the-experts. Tells you about my rabbit-holes.

Do I believe the experts? I do when they're right. Wait. What? You want me to believe them when they're wrong?

(boom, tish! I'm here all week folks)

Actually, the experts are not expecting me to believe them.

Belief is an epistemic attitude towards a statement, inclining one to act as if the statement is true. One can also act as if something is true, without believing it to be so, perhaps because it was the best option one had. One might even decline to act at all, on the basis that "all we have is an expert's opinion". Or one might make a contingency plan on the assumption that what the expert said is wrong.

The experts want much, much more. They us to have faith in them. They want us not simply to accept what they say faut de mieux, they want us not making contingency plans, to go all in, and only do things that make sense if what they say is true. They do not want us to research the subject for ourselves, and they do not want public debate. They want our uncritical compliance. They, after all, are the experts. They know much more than I ever will.

Whether they do is not actually the issue.

One issue is that we likely have no idea whether they are "experts" - unless we know enough about the subject to make our own minds up about it anyway. It's not enough for them to recite credentials, because we may not know what those credentials are worth; it is not enough that a journalist refers to them as an "expert", because we have no idea how reliable a judge the journalist is (and a lot of general reasons about journalists to suppose they are not).

Another issue is that not only do we need reasons to disagree with the "experts", we also need reasons to agree. If we don't know enough to disagree, we don't know enough to agree, either.

And finally, there's the whole free-will and rationality thing. We can no more outsource that than we can have someone else breathe for us. Doesn't matter who says what, it's our decision to act on it or not. Anything else is a denial of our humanity.

The proper course is to avoid having an opinion, and to formulate plans that are either independent of what the experts say, or to have contingencies in either direction.

The only commitments we should make are to our family. After that, it's all contractual, transactional, and conditional. Beware of people and organisations who say that is a terrible attitude, because they are usually after something from you for free. (If you can afford it, please go right ahead with my blessing. But if you can't, you should save whatever the resource is.)

What experts have to offer in exchange for our compliance is their authority, that is, following their advice is a sufficient defence against later charges of malpractice, manslaughter, dangerous driving, or whatever else. If I acted on the (perhaps expensive) advice of my lawyer, tax accountant, or doctor, the Judge has to back off the sarcasm and the Jury has to cut me a break. If I follow the law, the Government promises not to prosecute me. That's the deal, and it is a deal.

Absent the ability to make that deal, they aren't an "expert". They are just someone who has read too many books about too few subjects.

One should respect experts as people, until they sell out their reputations for government grants, honours and influence, or until they are exposed as frauds. Respecting them as people does not mean blindly accepting their every pronouncement. Indeed, respecting them as experts means putting in the work to understand and appraise their advice.
