I have a real world example.
Last week, I noticed a 3M Command Wire Hook kept falling down. Trivial fixes like cleaning the wall as described in the instructions did not work.
I tried to search for information about calculating the total load that is placed on the hook by 5 cables with different lengths and diameter along with various points of support.
After about fifteen to thirty minutes of trying to figure out statics (with no formal training besides the standard introductory college physics classes), I gave up. Then, I searched for information about the likely weight of each cable and assumed that the full weight was born by the hook.
The results led me to use a jumbo hook with a five pound capacity and it had not fallen down after 2 days.
And if this problem had nerd-sniped you a la Xkcd and you want to show off, this is the problem I faced.
From left to right:
Long headphone cable
Headphone cable held down on desk by a tissue box
Dell monitor with USB 3 and HDMI cables plugged in
USB cable supported by a pile of paper
Headphone cable, USB cable, HDMI cable wrapped together with a velcro strip
Two speaker cables plugged into a USB dac and amp
Another velcro strip
Headphone cable and USB cable connected to USB hub and different USB dac plugged into the hub
Velcro wrap holding the HDMI cable and two speaker cables together
Hook that falls down
Speaker cables dangle down to the floor
HDMI cable dangles loosely from the hook (not connected on most days)
(I am fairly certain that if you read this far, you ought to be doing something more useful than being nerd sniped by a physics problem.)

I wouldn’t fret too much about bias here. It’s hard to incorrectly read “0”. :)
Thanks for linking to a source.
I’ve also seen stores use Kimwipes to clean lenses.
What is the name of the coating?
Usually, you can look up somewhat detailed information about a lens coating using the Internet. Then, at the store, you can select the one you want.
For example, Sola had a patent on coatings that got transferred to Zeiss and Zeiss has a PDF that lists all the options and which coatings can go with which lenses.
Thanks for quoting the bit about Elua at the end. It is helpful to remember that despite Moloch, et al, humanity has managed some pretty impressive feats, even in the present day.
It’s easy to think that the counterexample of science in earlier posts is something accomplished “Once upon a time in a land far away.”
As a concrete example, I’m quite glad that the highly effective mRNA vaccines (Moderna/Pfizer) exist for the common man. They exist despite things like the FDA, the world of academic publishing, the need to find funding to survive, and so on.
Seconding UpToDate as a starting point and treating it like Wikipedia by using it as a source of references.
Then, you can use those references as a starting point in PubMed.
This suggestion is based mostly on watching my primary care physicians look things up at a major academic (university) medical center and conversations with physicians after using UpToDate + PubMed on my own.
>access if they wanted one
Based on a nearly universal sense (reading/personal experience/conversations with doctors) that it’s hard to find an in-network psychiatrist/psychologist who’s will to see a new patient, my prior on this is very low.
>motivation
That would help too. But there’s probably a large set of people who could be helped if the “access” barrier was reduced/removed on its own.
>difficulty?
Agreed for both rationalists and non-rationalists.
>knowing how to fix brains?
Which condition(s) specifically come to mind when you think of something that “clinical psychology research already has...covered”? I was unable to think of one off the top of my head.
I’m pleasantly amused to see you write that the one you liked turned out to be an unsellable floor model because my current bike gave the impression of having been an unsellable floor/some-other-issue model (clearance, last one in the store of that model, unknown brand, etc) when I got it.
I hope you have lots of fun with the new bike. Don’t forget to plan ahead for yet maintenance though. As you realized, it is no fun to try to move the heavy thing around on foot, especially with the battery.
While I haven’t evaluated their covid stuff, I agree with your assessment for other conditions where I’ve done some digging.
I meant to elicit some comments about whether the value of new-thing-digging-in would be sufficiently greater than what we could get out of making more optimal use of existing resources.
I’m going to use allergic rhinitis as an example below but I could probably have called it “disease X”.
There’s the set of things (e. G. Buy Kleenex, take those red round things, etc.) that the average person knows to do from surrounding people, culture, advertising, instinct, and the contents of store shelves. Let’s call this the low info & ultra conservative corner.
Then there’s the higher info and less conservative ground occupied by something like the MASK ARIA guidelines that implies that anyone who puts forth a real effort should be in pretty good shape after no more than a week with occasional exceptions. And to use EY’s idea here, the goal should be to get those Exceptions into the hands of Exception Handlers as quickly as possible.
Up to date is higher info than average-person-on-street but more conservative and certainly less efficacious than a pad of post it notes + MASK ARIA.
I’m not sure what the MASK-ARIA equivalent for long covid is but I imagine that if it exists, it might be good enough.
Have you (or a reviewer) compared their device with a traceable & calibrated device? I’m curious about how accurate it is.
Small thing:
“requiring high-filtration masks” is a broken link.
Have you looked at other resources that do something similar to what you’re asking? For example, what are the shortcomings of using Up to Date for this purpose?
Please don’t hide your work behind a surprise pop up that asks for an email address. I’m sure you have great stuff but ‘beware trivial inconveniences’.
The University of Texas at Houston, McGovern Medical School, Department of Otorhinolaryngology also has some good summarized advice for P100 masks.
They recommend 15 mL of bleach per gallon for sanitizing the mask.
Also, I have the impression that as long as the filter is not visibly soiled and it is not hard noticeably harder to breath with the respirator on compared to when you are not wearing the respirator, then the filter can be used indefinitely.
Most filter replacement schedules assume that you are working with some sort of vapor that will attack the filter rather than using P100 filters for particular protection alone.
Where does experimental data fall in your translation matrix? Some data is well within what you describe as hyperlocal (e.g. I hear raindrops outside ; it must be raining) but other data has a much longer journey. For example, if you see an image of Mars from JPL labeled as “Taken by Sojourner on date… Time… Place… With such and such camera facing a heading of...degrees North”and with colors calibrated with the color chips with spectral frequencies x, y, and z mounted below the camera”, how would that picture do after going through your translation matrix?
I’m specifically picking on Mars because (if I recall correctly), people did think it was reddish after looking at imagery for some non negligible amount of time until realizing that they messed up the photo processing.
And this is not easy for anyone on Earth to verify either. There are literally no humans on Mars who can say “Stop. You are wrong. The dirt is dirt colored, not red.” It would be entirely fair to say that a mistake like that can not be corrected at all without spending billions of dollars on another Mars mission.
I hope this example is close enough to the physical world;I am not familiar with what you mean by simulacra levels. I hope you can see how these concerns have analogs that are much closer to home without explicitly name dropping any terrestrial historical events.
If anyone’s feeling nervous about using this advice is day-to-day situations (in other words, I won’t even try to tackle BillK’s example of weddings, children, and mortgages), here are 2 positive experiences I’ve had recently.
At work, after spending >1.5 hrs digging into a problem, I called a coworker for help. We spent an additional 20+ minutes digging into it to no avail. Finally, I realized that I had typed the year wrong, repeatedly used the word “oops” and “mistake”, and the call ended shortly thereafter. Now that it’s been a few days, I can confidently say that there were no negative repercussions from that. Instead, I was able to complete the task quickly thereafter.
At home, a family member and I were trying to do something new that we had learned by watching videos and reading written instructions. I skipped about half the steps and after saying that I’d been a fool, we were able to start over and finish after a few minutes. The family member did not say anything negative about my mistake afterwards.

Other comments on the post (https://slatestarcodex.com/2020/03/23/face-masks-much-more-than-you-wanted-to-know/) indicate that fit testing is much easier to accomplish with an elastomeric respirator (often referred to as “P100” due to the filter).

Unfortunately, even if it is not hard to get a good fit, fit testing may be cost-prohibitive. After checking the prices for 3M, MSA, and Allegro, I found that the median price of a fit test kit is $363.50 (25th percentile is $296.25 and 75th percentile is $463.36).
After you buy all the pieces (2 respirators with plans to return the one that doesn’t fit, 2 sets of cartridges, fit test kit) from Amazon.com and Fisher Scientific, the cost is >=$290 as of January 8, 2022 excluding shipping and taxes.
A 2010 journal article found that if you ask 3 different people to measure the probed pocket depth, they will agree exactly about 55% of the time and they’ll be within 1mm of each other 97% of the time.
There are also other symptoms to look for besides depth before a diagnosis should be given (e.g. bleeding and bone loss).
The American Academy of Periodontology published 2 tables that walk the user through staging and grading periodontitis. The tables include the following factors:
Amount of bone loss visible when looking at the tooth directly
Amount of bone loss visible from looking at an x-ray
Number of teeth with bone loss
The type of bone loss
Maximum probing depth
Whether there’s a pattern to the affected teeth (are they all next to each other?)
Amount of biofilm/plaque
Smoking: Yes or no
Diabetes: Yes (and if yes, how well-controlled is it) or no
