climatologists have more work to do, proving that climate change is due to CO2 emissions from human activity. That's why I suggested that they need to do two things:
1. Explain the rise in earth temperatures with the greenhouse effect of (raised) CO2 levels.
2. Make a prediction of how temperatures will rise in (say) the next 10 or 20 years. — TheMadFool
What's the best gameplan for us given that we don't know the truth about climate change? Should we assume climate change is real or should we assume it isn't and act accordingly? — TheMadFool
Try to keep up.

You know, I will repay you and your ilk for this contempt. — baker
Riiight, you are the embodiment of kindness. — baker
We weren't talking about what happens on the ground between doctors and patients, so this is irrelevant.
— Xtrix
It's the level on which trust in the medical system is build, or destroyed. — baker
No one is arguing perfection.
— Xtrix
Given your righteous indignation, given your contempt, your hatred: only perfection justifies and warrants those.
If you want to be justified hate people for not thinking and acting the way you think they should, then you better be perfect. — baker
What does it help if the national health institute says one thing, but on the ground level, even medical personnel is skeptical about vaccination? — baker
So the question is: how many times does the consensus of experts need to be proven true before we simply (as laypeople) trust them?
— Xtrix
Irrelevant. What is relevant is what happens on the ground level.
Ie. in terms of medicine, what is relevant is how actual doctors and other medical personnel actually interact with actual patients. This is the level at which trust is build, or destroyed. — baker
Irrelevant. — baker
No, I do not believe governments act by and for the people. — NOS4A2
We don't know if vaccinated people transmit at a lower rate, per the internet. — frank
If it was so easy to find the answers, then why not provide them here for everyone's benefit? — Harry Hindu
Here's a question no one has asked: — Harry Hindu
What threat are the unvaccinated to the vaccinated? If there is still a threat even though you are vaccinated, then why get vaccinated at all? If I can still carry and spread the virus even though I'm vaccinated, then what purpose is there to get vaccinated? — Harry Hindu
about the actual position that variance in degree of support within the cohort of experts is not well correlated with a theory's predictive power, — Isaac
People who nit-pick fluctuations/change, and then use them as evidence that science or government should not be trusted, are unfamiliar and uncomfortable with how the scientific process works. — James Riley
The WHO likewise reliably gave out false information early on. — frank
Now you have to show what mechanisms exist to make it impossible (or less likely) that a majority on any one question could be the result of any of these other factors, of which conflict of interest is just one. — Isaac
Then it is a contortion to say that they have no other information. How can they use "a number of reasons" yet also have "no other information"? — Isaac
I’d say the WHO, the CDC, the AMA, etc, represent a majority of experts. This is all most laypeople know. So is it right to trust the CDC?
— Xtrix
No. — Isaac
So you're saying that when there's two competing theories, there is always overwhelming evidence in favour of one? — Isaac
Yes, but you've given no evidence at all that the theories supported by the majority of scientists have a greater quantity of these properties than theories supported only by a minority. — Isaac
But maybe we could do something at societal level, because it does not seem normal to me that so many folks would chose to go irrational. We're doing something wrong. — Olivier5
Then you've agreed to fight it out on Isaac's terms, but I'm not sure you have to. — Srap Tasmaner
This is what I wanted to get at: are we compelled interpose a step where we play at doing social science every time we face a decision about how to be a good citizen, or just a good person? — Srap Tasmaner
I think one of the things that's getting mixed up here is the difference between the question "should we trust experts opinion?" (the answer is yes) and "should we trust the majority of experts over the minority of experts of the same education level?" the answer is no - by specifying that they're of the same education level we've removed (or severely limited) the one variable which had a link to 'rightness' (education level) so the remaining variables responsible for the within class variance may or may not be linked to 'rightness'.
— Isaac
I get that. It's an interesting point, a reasonable point, but what kind of point is it? — Srap Tasmaner
I'm just correcting Xtrix's first error mistaking variance in a population with variance in a stratified cohort. — Isaac
We should rather start with this simple truth and work outward to understand why it’s true— not deny it’s truth altogether, as if consensus means nothing and science means nothing.
— Xtrix
Yes, we should start with the conclusion we like and then keep changing our reasoning until we justify it regardless of any mathematics, evidence, or line of reasoning to the contrary - what a brilliant way to go about thinking over a topic. I couldn't have written a better explanation of exactly the process I was describing in theory selection. — Isaac
I'd like to talk about more about what Plato is saying and whether we ought to care, but instead I'll close by noting yet again the cross-purposes in this damn thread: one side (mostly that's just you Isaac) is talking about this as an empirical question, and the other side (this would be you @Xtrix) sees all Isaac's talk as a shocking failure of citizenship. — Srap Tasmaner
If it turned out that 97% had ties to the fossil fuel industry would it still make sense to go with the majority? — Isaac
it's been stated from the beginning that there is no other information that the layman has beyond the majority.
— Xtrix
Then you too are engaging in "ridiculous contortions" — Isaac
If you're arguing it isn't correct, then you're essentially saying that a laymen ISN'T better off going with the overwhelming consensus, and in fact cannot know either way -- perhaps it's 50/50, etc. Which is an absurdity, as demonstrated by the facts.
— Xtrix
What facts? — Isaac
One obvious way to tie-off this daisy chain is trust. At some point, early or late, you trust someone or some institution. Done. But don't we have to talk about how you make such a trust decision? Maybe not. Maybe people just choose, but you're not going to like everyone's choices of whom too trust. Yuck. — Srap Tasmaner
But the aptness of that analogy is exactly what Isaac is disputing, isn't it? — Srap Tasmaner
I'll pose this again:
Should laypeople go with the 97% consensus on climate change? Why or why not?
— Xtrix
At the risk of flogging the dead horse of statistical misunderstanding, I'll try another explanation. Remove climate change and replace it with issue X. — Isaac
On issue X the facts are such that two possible theories can be both held without being falsified by them (you're familiar with underdetermination of theories?). Theory X1 is favoured by experts with green eyes, theory X2 is favoured by experts with blue eyes. 97% of experts have green eyes. Now does it benefit the layman in any way to go with the 97%? — Isaac
To show that the layman (assuming he's interested in being right) is better off pinning their flag to theory X1, you'd have to show that the variance in support for each theory is caused by (or at least correlated with) the variable {rightness/accuracy/utility}, otherwise the fact that theory X1 has a high score in the variable {numbers of experts supporting} has no bearing at all on the variable of interest. — Isaac
in opposition to any understanding of statistics of or the way expert discourse works — Isaac
They can either attack the 97% statistic, or go with the 3% :cool: — Wheatley
a study has never been done about this
— Xtrix
Yeah it has. I mentioned it. It's why we're talking about this. — Srap Tasmaner
There's a fair amount of noise in any umpire's calls, and in umpires taken as a group. — Srap Tasmaner
I'd say the computer would confirm the majority opinion, more so with higher consensus.
— Xtrix
Then you'd be wrong. — Srap Tasmaner
I haven't looked at Fangraphs in a while, but the "average called strike zone" tends to move around from year to year. — Srap Tasmaner
Here's one example I recall: umpires are, as a group, somewhat reluctant to make game-deciding strike calls. That is, when a called strike would decide the outcome of the game, then and there, umpires are slightly more likely to call a ball a pitch they would usually call a strike. — Srap Tasmaner
Alternatively, as Yohan pointed out earlier, this undermines the idea of majority consensus. If it's just linearly related to intellect then the majority are almost certainly wrong, as they don't represent the cohort with most intelligence. The group that are right will will one of the minorities but we won't be able to judge which (are they the most intelligent, or the most stupid?) because we won't understand the arguments. — Isaac
All (sufficiently detailed) theories about how to handle COVID are new theories, — Isaac
There are a few serious side effects, most notoriously the blood clots that in "Some cases were life-threatening or had a fatal outcome", according to the UK Government. — Down The Rabbit Hole
It's part of how Astrazeneca got a bad reputation. I've heard it on the national news, and I'm sure they can fact-check better than I can. — baker
Aww. And completely excuse the men. Because, hey, boys will be boys, right. — baker
