as a layperson, under what circumstances might it be reasonable to be skeptical about the claims of a majority of experts on a subject?
when the incentive structure in that domain is broken
when the 'consensus view' is the product of social engineering; expert dissenters institutionally excluded for plausibly political reasons
when continued gov funding and/or career opportunity looks like it depends on having advanced the 'consensus view'
when you notice that counter-evidence is reflexively dismissed; institutional messaging pretends it doesn't exist. uncertainties not acknowledged.
when expert dissenters' objections aren't adequately addressed by adherents to the dominant narrative
related "[The experts'] areas of specialty & years of experience made no difference. When experts declared that events were nearly impossible, 15 percent of them occurred nonetheless. When they declared events to be a sure thing >25% failed to transpire theatlantic.com/magazine/archi…
when you have low confidence that there even *is* a majority agreement (has every expert been polled?) ie. the claim of majority consensus is itself suspect
when powerful interests would see their power enlarged to the extent that action followed the alleged consensus
the more of the above criteria fit, the better the grounds for being suspicious of the claimed consensus view
(what proportion of those prominently making the claim are actually mouthpieces, propagandists rather than experts?
what proportion of the experts have independently looked at the question rather than automatically accepted the apparent consensus opinion of their peers?)
even if you're an expert whose independent opinion would be valuable there are cases, I reckon, where it can be professionally expedient not to look very closely at a hot issue
when the dissenters seem to do a better job of steelmanning the case for the consensus view than vice-versa
when the institutions claiming to represent majority expert opinion already made confident claims that turned out to be false
one of the replies was 'well experts were right ~75% of the time!'
no though. if a predicted event happens, that doesn't validate your claim that it was a 'sure thing'
"it's certain that the coin will land on heads"
experts claims weren't *clearly falsified* ~75% of the time
simpler way to make the same point: i say it's impossible that the coin will land on heads. the flipped coin lands on tails. we don't take this to mean I was correct about a heads result being impossible.

The site cryptoart.wtf by Memo Akten (@memotv) claims to report the ecological footprint of cryptoart NFTs. But the calculation it’s based on is not valid; we can’t legitimately derive an ecological footprint cost per unit of gas in the way it tries to.
thread
On this page memoakten.medium.com/analytics-the-… Memo explains how the energy cost of a piece of crypto art is calculated on the site. The calculation depends on adding up the gas costs of all transactions associated with the artwork being analysed.
He writes:
“Since the energy required and footprint of mining a block is independent of its contents and number of transactions, the Gas required by a transaction is representative of the portion of a block’s footprint it will incur

a video metadata standard designed to allow creators to mint (tradable) patronage NFTs corresponding to a predefined number of patron slots per video. the current NFT holder is credited in-frame (via player overlay elements) by supporting players.
+ smart contract (suite?) for minting & transferring this kind of NFT. contracts allow buyers to specify how they'd like to be credited (‼️moderation concerns) and transfers some % of trade price to the creator each time such an NFT changes hands (‼️what if the creator's dead?)
if i had a penny for each time i've been told "a free market could only work if people were perfectly rational" i'd have about three pounds. that's altogether too much.

it gets things back to front. one of the biggest virtues of a free market is its robustness and anti-fragility. all it needs are plain old *approximately rational* people to give constantly improving results.
a key reason: on a free market gains from choosing well and costs of choosing badly apply in large part to the chooser. he's well incentivised to consider carefully. this is v different to the incentives that choosers face under repdem voting contests.
if a medical treatment satisfies mandatory government licensing requirements its more likely to be safe than it would be if there were no such requirements, right?
not necessarily. if a government agency claims the treatment is safe (even implicitly, by allowing it to be used), most people are satisfied that it's safe, and the manufacturers aren't under much pressure to do additional safety research.
if the government took no position about the treatment's safety, and it was well understood that the buyer should beware, people would be more cautious.
