I think people who find that weird just don’t appreciate how much sway authority has over midwits. They really don’t care how nonsensical the argument is: as long as they consider the person or institution making it authoritative on the topic, they will accept the conclusion.
I already knew that before, but the pandemic really impressed that on me. Many people simply cannot comprehend that someone with no relevant credentials might be right against someone who they think has them, regardless of how clear it is that they are in fact right.
What’s funny is that, in many cases, the people they consider authoritative on a topic don’t actually have relevant expertise in virtue of their credentials (think about how people trust physicians to opine on epidemic modeling), but it doesn’t matter. What matters is perception.
This is very weird if you are reasonably intelligent, but that’s how many people function. And to be clear, it’s not even necessarily a bad thing, because it’s not obvious at all that it would be better if people didn’t defer to authority like that.
In fact, I think it’s pretty clear it would be much worse, because people who are incapable of seeing when someone they perceive as authoritative makes an obviously fallacious argument clearly aren’t going to be good at adjudicating the facts for themselves.
You see that with people who embrace antivax nonsense. But the fact that deference to authority is necessary only highlights how important it is that knowledge-producing institutions be truth-conducive environments and that people correctly associate credentials with expertise.
The problem is that often neither is the case or much less than we’d like it to be. To be clear, I don’t even think the crack pipes story is a great example of that, but that’s just what prompted those very general observations so I’m just rolling with it.

Here is how Romer reacts to a perfectly reasonable point in response to his latest blog post. In a community that values truth and intellectual integrity, he would immediately lose all credibility after that, but instead many economists are *praising* him for it. ImageImageImage
The saddest thing about this is not even what it reveals about the state of economics, which is far from the worst field in that respect, it's how willing Romer and so many others are to debase themselves by jettisoning truth and intellectual honesty for ideological reasons.
Indeed, this isn't just intellectual corruption, it's *moral* corruption. Romer knows perfectly well that it's a good point, but he is a coward and a fraud, so he prefers to side-step the issue and reply with abuse to flatter the prevailing opinion among his peers.

Currently being further radicalized against science by economists gushing over this post, and pretending that these graphs convincingly show a strong effect of personal insecurity on black patenting, instead of making it clear that it's probably just noise. ImageImage
I don't even get what the story is supposed to be here: the graph shows that black patenting was highest when lynching against blacks was highest and stayed low after lynching violence receded, so what the fuck do people think it shows?
Sure, you can tell a story in which once anti-black violence has peaked around 1900, it had a large effect on black patenting that persisted long after lynching became much rarer, but this hardly seems to be the most obvious interpretation of the data.

Why do I have the distinct impression that most of what therapists do is tell their patients that their insane worldview is not in fact insane?
I was kind of joking but also kind of being serious here. In theory, it could be very useful to see a therapist because he could help you see that your perception of the world is wrong, which can be hard for your friends and loved ones to do because it puts them in a hard spot.
But everyone I'm close to who is seeing a therapist seems to have their worldview validated by him/her, even though I personally think the worldview in question is deeply mistaken and a big part of why they are miserable, so that doesn't seem very good.

As I have argued before (cspicenter.org/blog/waronscie…), this kind of chart is totally fake, because the methods used to estimate the basic reproduction number of SARS-CoV-2's variants are unreliable, but it's worth pointing out that basically everything else on that chart is fake. 1/n
We don't really know what the basic reproduction number of a virus is, and in fact the question doesn't even make sense, because the basic reproduction number of a virus is not an intrinsic property but depends on the context such as population density, culture, etc. 2/n
For instance, take measles, which is often presented as the most transmissible infectious disease with a R0 of 15 as in the chart above. But where does that number come from? 3/n

I agree that, since Ukraine's accession to NATO is not imminent, it wouldn't make sense for Russia to start a war over it now. 1/n
But the fact is that Russia has *not* started a war over it yet and this line of reasoning is precisely what makes me think that it won't and that it just wants the US to believe that it *might* to force Washington to take its security concerns seriously. 2/n
Insofar as this has forced the US to the negotiation table to discuss those concerns for the first time in a very long time, you could say that it has worked, but what is unclear to me is what concrete advantages Russia is expecting from the process. 3/n

It's funny a lot of people attack affirmative action on the ground that Asians are discriminated against by elite universities, but never because Whites are, even though the data show that — at least for non-legacy applicants — both claims are true. edition.cnn.com/2022/01/24/pol…
If you point that out, I'm sure people will come up with all sorts of justifications, but they'll just be ad hoc justifications. The actual reason is that, among educated people, it's socially acceptable to complain that Asians are discriminated against but not that Whites are 🤷‍♂️
Personally, I have come to embrace the view that, in a multicultural society, a measure of affirmative action is probably desirable. You may agree or disagree with that view, but at least it's honest.
