“US sales of vinyl disks just surpassed CDs” (translation of the quoted headline).
I’d add that Lindy also applies to dimensions others than time, in a measure.

Over the dimension of “jobs”, vinyl players had 3 (playing music, pleasant piece of furniture, hobby) whereas CD players had 1 (playing music). Less Lindy across that dimension too.
As another example, a tech that is used in multiple countries across the world is Lindier than one used in only one, all other things equal.

That’s because the latter might work because of conditions specific to the one country adopting it; less likely for the former.
Basically Lindy uses sample size as an estimate for result robustness.

Time is a sample size, geography another, etc.

What do I think an educated society means?

Nothing about graduation rates (literacy rates, yes).

Instead:
– Knowing what matters for society to work well
– Being able to find a value-adding role in society
– Having learned that personal improvement is achievable

Not banal

1/6
1) Knowing what matters for society to work well

Things such as:
– What brings prosperity?
– What did countries that were wealthy and democratic do (or didn't do) that caused them to become poor or totalitarian

Seems banal, but…

2/6
…we only discuss how good it's to be prosperous or democratic without discussing how to get there or how not to fall back to the default state (poverty / absence of rights)

BEYOND THE CHECKLIST

A problem of many organizations is that they are aware of the needs of employees (impact, recognition, growth, fair salary, etc) but fulfill them as they would with a checklist: let's do this superficially, checked, done.

Some examples (& solutions) ↓

1/8
Example #1: recognition.

Many companies and managers know that employees want recognition.

But they fulfill this need in a very superficial way. With a small internal award, a certificate, etc. Top red flag: it's HR-driven and/or feels cringe.

2/8
The alternative:
– make it personal: it should come from the boss or the boss' boss.
– make it congruent: a moment of recognition followed by a year of no recognition feels (and likely is) fake.

Whenever we desire an outcome but not the actions that would make us achieve it, we end up with inaction, busywork, shortcuts, excuses, and, ultimately, frustration.

(a thread of highlights from the first chapter of my book "The Control Heuristic")

You probably do not have a decision-making problem, but an action-taking one

2/14 Image
Decision-making is not the same as action-taking.
The cortex is mostly responsible for taking decisions, and the ~basal ganglia determines whether we act on our decisions.

TIPS FOR EFFECTIVE DELEGATION

1) Minimize the chance of misunderstandings:

Explain:
– what's too little
– what's too much
– common mistakes
2) Explain why you need it done.

Not who asked for it. What it is for. What happens if it's not done. (And what happens if it's not done well enough.)

Tasks whose rationale isn't explained relevantly are done badly and/or at higher emotional cost
3) Pre-empt inaction and failure.

Ask them and yourself:
– Why might they not take action?
– Why might they take action and yet fail?

Footnotes are my favorite feature of my book Ergodicity (from which the screenshot below is taken).

In fact, there’s plenty of bolded text in the footnotes.

A few examples in this thread. Image

The recent wealth tax increase in Norway was expected to bring an additional $146M in yearly tax revenue

Instead, an estimated $54B-worth of ultra-rich left the country, leading to a lost $594M in yearly wealth tax revenue

A net decrease of $448M+

(sources and calculations ↓)
The Guardian estimates the wealth of the relocated millionaires at 600B NOK, or $54B. That would have been taxed at 1.1%, which means $594M in wealth tax lost

Norway raised NOK 16.1B = $1.46B in wealth taxes in 2019 (page 3 of the PDF below); increasing the wealth tax from 1% to… twitter.com/i/web/status/1…
Plenty of replies who seem to think that leaving the country to keep one’s money is greed, but implementing a wealth tax to get someone else’s money isn’t
