I didn’t imply an argument. You inferred one, because you insist on bad attempts at mindreading.
Which isn’t what I did…
I shouldn’t need to explain the difference between purchasing from a suspected charlatan to acquire the evidence they are one, and purchasing what you believe ‘[The author] to be interested in getting at the scientific truth and presenting the public with information without emotionally charged language, hyperbole, etc. He writes with clarity, and he presents definitions, maps, graphs, etc. in a way that should be helpful to lay people who are not trained scientists but want to learn about the issues.’
Imagine three scenarios (names made up, with no relation to anyone so far mentioned…):
Buck publishes a newsletter of his test results on various snake oils, and learns of a new one marketed as a cure all. He looks up the purveyor, and finds he has a history of marketing quackery. Suspicious, he checks if others have tested it already, and makes notes of their findings, but as an time-honored and trusted tester of tonics he buys some to test himself. He tests it, confirms it doesn’t work, and publishes his results, citing the others he is aware of who have already tested it as well so others can check for consensus.
Teddie has a backache, and sees some snake oil marketed as a cure-all. He believes what the purveyor says of himself, and either doesn’t see what he has said or done in the past or doesn’t care. He likewise either does not check to see if anyone has tested the new tonic, or knows that people have and found it doesn’t work and again doesn’t care. And so he buys some. He uses it and feels a bit better, but suspects it might be a placebo anyway and resolves to not buy that particular tonic again.
Krisper hears about a snake oil marketed as a cure-all. Curious, he looks up the purveyor. Finding the purveyor has a history of marketing quackery, he is suspicious of the claims. So he checks if it has been tested, and finds the work of Buck and others showing it is a placebo at best. As someone who doesn’t make a habit of personally testing snake oils, he is satisfied with the existing quality of scholarship and determines purchasing it would be a waste of money.
Do you see how only ‘Teddie’ has been conned, since only ‘Teddie’ has given the snake oil salesman his money believing that the purveyor is credible and the tonic has a reasonable potential to work? I hope you do.
My use of the word ‘significant’ was deliberate. I intentionally did not use a word implying relative proportions, because relative proportions are completely irrelevant to the point of the argument.
It is not a question of whether 1%, 10%, or 99.99999% of the science is ‘settled’, only the importance of what is ‘unsettled’. So the meaning of ‘significant portion’ is not uncertain in any way that matters, it means ‘a portion (of any size) that matters if wrong’.
Examples:
It could be that 99.99999% of the science is unsettled, but the settled 0.00001% controls for 99.999999% of the impacts. In this case, the unsettled portion is insignificant even though it is nearly the entire field.
On the other hand, if the reverse is true then the unsettled portion is significant even though is represents a vanishingly small fraction of the field.
Since we know the percentage of impacts resulting from settled science is sufficient to warrant massive global action, then even being wrong about the ‘unsettled’ portion can’t support a different course of action. As such, the ‘unsettled’ portion is known to be insignificant with respect to global action.
Did I merely ‘assume’ the categorical falsehoods I directly quoted from Koonin’s book in my previous post? Or are you ready to admit that, just maybe I’m right when I say that the book contains demonstrable evidence of Koonin’s dishonesty and/or incompetence?
