> The normal distribution is not about default humans. It’s about the fact that in many statistical studies, the characteristics of the population tend to cluster around a mean. So if the average height of the human population is 5 foot 7, then most individuals will be around that height. NO!! This is known to be false. The average does not mean "most" measurements match the... mean. And it actually does happen that…

But the anecdote you're relating doesn't really say anything about the ability of a normal distribution to describe a population. It's just a natural consequence of having a high-dimensional multivariate distribution without accounting for correlation or covariance, along with a low sample size. If you have 4,063 pilots and you take the middle 30% of ten (assumed independent) factors, you're looking at 0.3^10 * 4,063…

Yeah ok my comment was unclear. My quote from the OP isn't false and the "no" in capitals is over the top and wrong.

Yet the airline story does show that the mean (a bag of means of different factors) can be used -- is often used, wrongly -- to construct an average standard (or ideal) specimen. That specimen is then used as a reference, yet it doesn't exist.

Also

1/ The normal distribution without a standard deviation tells us little about where a specimen lies in a given population;

2/ A normal distribution is often assumed when next to nothing is known about the actual distribution, and that's an even bigger problem, especially in social sciences.

I highly recommend watching the new Cosmos with Neil Degrasse Tyson. When it first came out I made a big production of it with my kids. They got to eat popcorn and drink soda while we all watched the series together. They (and I) still look back on it fondly.

I would suggest passing on Neil deGrasse Tyson or at least taking a second look. His smugness alone is enough reason for me to not have anyone, especially kids, look up to him. Not to mention, he's often just flat out wrong. I personally cannot stand even seconds of hearing him speak, and I find him insufferable. It's his lack of humility that really gets to me. The original Cosmos is still available, and it's quite…

This kind of vitriol makes me sad at humanity

Self-censorship is the other half of this problem. How many of us here have self censored our writing out of fear of painting a bullseye on our backs? The more you have to lose, the more cautious you are. If you’ve spent a lifetime studying a certain field, building a business or becoming a well know expert, you risk having it all taken away if you provoke the ire of the mob. And the mob has nothing to lose and everything to gain by targeting well known public figures.

The result is that absurd ideas enter the public psyche and not one expert will risk their career by contradicting them.

The democratization of publishing is an exciting breakthrough in all of human history. I’d rather have it than not. But this post-truth era that is emerging is worrying.

Within the original article, there's a reference to this paper: https://www.journals.uchicago.edu/doi/full/10.1086/704991 (the author seems well-credentialed in the physics realm: https://en.wikipedia.org/wiki/Chanda_Prescod-Weinstein).

Does anyone have any insight as to what this paper's trying to show? Looking at the beginning of the conclusion:

> The central argument of this article is that white empiricism limits who is authorized to make claims about physics and that this is damaging to physics and alters its empirical direction.

All I can get from it is that the author's trying to point out that (1) science has emerged in dialogue between humans, and (2) we should be mindful of who exactly's participating in that dialogue as that influences the kind of science that emerges. This seems somewhat reasonable and a good justification for encouraging a diversity of perspectives.

But what new insight/perspective does the paper really contribute?

For example, earlier in the same paper we find this when talking about some of the author's perceived failings of string theory:

> Surveying what should happen next, there are at least three distinct possibilities:

> 1. Patience is required, and evidence is coming.

> 2. String theory has failed to succeed in expected ways because the community—which is almost entirely male and disproportionately white relative to other areas of physics—is too homogeneous.

> 3. The scientific method overly constrains our models to meet certain requirements that no longer serve the needs of physics theory.

> ...

> The second option is effectively unconsidered in the literature. Instead, the case for the third option has been made. This is a curious turn of events. Rather than considering whether structural and individual discrimination results in a homogeneous, epistemically limited community, physicists are willing to throw out their long-touted objectivity tool, the scientific method.

The author hints that "there are at least three distinct possibilities", and from what I understand of postmodernism, it's what's hidden in the margins of the text, i.e. what's left out of a philosophical argument, that usually unravels that original argument entirely. One glaring missing possibility is that we just haven't yet found a better theory or approach that more accurately fits observations than string theory. If that's what the author's trying to convey with option 2, it seems like a pretty unnecessarily racialized and facile way to do so to me, and still hints at an important omission that there may be a totally non-racialized explanation for why string theory hasn't lived up to expectations.

Maybe I haven't read enough postmodern literature to be able to appreciate this paper's contributions (maybe they're subtle), but from my first reading it ultimately just seems like one long complaint that black women have been excluded from physics by white men, which isn't really a novel contribution in 2020 if the theme already made its way into popular films. For someone so well-credentialed, I really would've expected a more substantial epistemological critique, or at least practical recommendations as to how to cultivate an environment that encourages a diversity of perspectives. Or, even more practically, if the author had actual evidence of bias (i.e. practices of actively excluding people of certain groups from the physics community), why not address that in the appropriate forum?

It's all very strange to me, including why a paper like this is cited in Scientific American.

NOVA has been undergoing a similar decline. The latest episode was about the nanoarchitecture of butterfly wings, which is a fascinating topic. A researcher mimicked the nano structure onto a piece of metal, a disk the size of a nickel, which is so hydrophobic that two disks close to each other would float, as it had essentially a bubble trapped between them. The subtext of the show was about "combating climate chang…

That might be silly, but its not downright misrepresenting concepts the way this article is complaining about, e.g.

> “First, the so-called normal distribution of statistics assumes that there are default humans who serve as the standard that the rest of us can be accurately measured against."

What can I put in my house today that will let my children discover science and physics the way Scientific American let me discover them as a teenager?

Scientific American? Just because this post had issues with one article doesn’t invalidate the entire periodical.

Just because this post had issues with one article doesn’t invalidate the entire periodical.

In my estimation, it's become so shallow that i don't even bother following links to it from HN anymore. Whenever i see an entry in HN, i just move on.

The problem with NOVA in this TikTok era is the hour long format that was designed for broadcast TV. A topic with 10 minutes of material is stretched into 45 minutes with unnecessary drama and reenactments as filler.

Like the kids say these days 'Ain't nobody got time for that'. I'd rather watch a 10 min video on Youtube that covers the same topic.

Does anybody else wonder at people who insist on using three names? Some actors do it, too, like Hayley Joel Osment and Brian Taylor Green. It just seems pretentious to me, like somebody insisting on using a title outside of their official duties.

Sometimes the media does it, which is a good thing for people with different middle names. Here are a few examples I thought of. Not good:

As far as the veracity of Medium articles go, this is from the Wikipedia page describing Medium: The platform is an example of social journalism, having a hybrid collection of amateur and professional people and publications, or exclusive blogs or publishers on Medium,[3] and is regularly regarded as a blog host. I tend to take things I read on that website with a grain of salt.

What does Medium have to do with anything I wrote?

Medium is where the piece we’re talking about was posted - “The Shameful Decline…”.

While the article in SA does seem appalling, I don’t see this single article’s publication as justification for this broad indictment of SA. It’s concerning, yes. But it’s ONE ARTICLE, and that’s all the piece talks about. OP may well be right, but they haven’t shown it by the citing of ONE ARTICLE.
