TIL: the paper that coined “all models are wrong, but some are useful” contains considerable further practical wisdom. “The scientist must be alert to what is importantly wrong. It is inappropriate to be concerned about mice when there are tigers abroad.”

George Box (the author) writes about the career of pioneering statistician R.A. Fischer, who was employed on an agricultural field station, and did most of his early work on varieties of dung (as fertilizer), with which he was in frequent physical contact.
I made a similar point in “Going down on the phenomenon”: you have to be willing to get your face wet. meaningness.com/metablog/going…

Fascinating story about engineering education, rocket science, race car tires, technical rationality’s limits, and embodied understanding!

Can anyone from @NASAJPL say whether it is actually true? Confirms my priors, but I can’t find online verification.

@NASAJPL The problem with contemporary engineering education, h/t @JohnDCook. Kids these days

@NASAJPL @JohnDCook Engineering education used to begin with kids helping fix up old cars or disassembling WWII surplus electronics.

A process of apprenticeship (cf @SamoBurja video I retweeted earlier via @_awbery_)

& embodied, embedded, extended, enactive cognition!

🎙 Robert Kegan explaining his adult developmental theory, with @dthorson

“If you want to be Stage 5 because all the cool kids are, that’s a Stage 3 aspiration. If you want it because Stage 5 is the Correct way of thinking, that’s a Stage 4 aspiration.”

anchor.fm/emerge/episode…
@dthorson Daniel asked Kegan about his claim that no one reaches Stage 5 before age 40. Kegan said that’s what’s in the data from their measurement process: zero cases.

This is somewhat puzzling…
@dthorson Other researchers using similar but not identical measures find “meta-systematic cognition,” seemingly analogous to Kegan’s Stage 5 thinking, starting for some in late 20s (partial intellectual understanding of it sometimes starting early 20s).

Informally I think I see this too.

@KevinSimler @context_ing Right, I nearly added a tweet about principal-agent when originally replying to you!

There are lots of categories of things that offer pieces of the service one would want, but most of them are fatally compromised by principal-agent conflicts.
@KevinSimler @context_ing To take the original example, there are insurance advisors and insurance agents (different things), but they are mainly or entirely compensated by the insurance companies, acting as outsourced/freelanced sales people, so their “advice” is unreliable.
@KevinSimler @context_ing And, they don’t do the main thing you actually want, which is not selecting an insurance company, but dealing with their paperwork and screw-ups and (likely-fraudulent gray-area) coverage denials.
