NASA spent decades perfecting a hiring filter that has nothing to do with technical skill. The researchers found test scores and flight hours couldn't predict which crews held together, all it needed was one bad mood to destroy an entire mission. Here's what they screen for: 🧵 Related

After a civil engineering prof mention that the people in their department who work on water quality/treatment tend to drink out of the water cooler and not drink tap water, I tried getting a water filtration system. "Everyone" says Vancouver has really good water, so I didn't expect much, but the system's pre-filter catches a lot of green flecks (copper). The RDA of copper is < 1mg, which is on the order of these flecks, so it seems like I was ingesting many times the RDA in copper daily. Related

Their words
it's, I think, critical that ideas don't die on the vine because you've got, um, a visual expression that doesn't match what everyone else expects. Sometimes people will just filter them out because they don't look right.

That is absolutely possible. I’m actually putting less credence on that one just because you need to happen every single time. If even one, I mean, this goes back to John von Neumann pointed out that you don’t need to send the aliens around the galaxy. You can build self-reproducing probes and send them around the galaxy.

Nothing matches. Show everything
A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.

About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
