Happy New Year! On Monday, we start tweeting about #AdamSmith 's whole #WealthOfNations at the rate of about a chapter a day! Don’t miss it! #WealthOfTweets #SmithTweets

Today, we’re looking at “The Introduction and Plan of the Work” because although it is New Year’s Day, we, the SmithTweeters, are still Very Serious Smith Scholars. #WealthOfTweets #SmithTweets
TFW you start reading “The Introduction and Plan of the Work” and realize that elevator speeches were invented before elevators. #WealthOfTweets #SmithTweets
How hard people work &how many are working is more important to national wealth than resources &climate. So much for Montesquieu et al saying climate determines levels of industriousness or laziness. (Int. 3) #WealthOfTweets #SmithTweets
We swear we’re going to come back to Smith and this “savage nations” phrase he keeps dropping. We just can’t do it on January 1st. (Int. 4) #WealthOfTweets #SmithTweets
The mystery he wants to solve is why in poorer nations people seem to be working all the time while in wealthier nations they have so much more leisure. How do nations move from one state to another? (Int 4) #WealthOfTweets #SmithTweets
That’s the crucial thing to remember about Wealth of Nations. We aren’t trying to solve the mystery of poverty. Poverty/subsistence is the natural state of humans. We’re trying to solve the mystery of wealth. #WealthOfTweets #SmithTweets
Don’t forget to join us on Monday for Book One, Chapter One of Smith’s Wealth of Nations! #WealthOfTweets #SmithTweets

global health policy in 2020 has centered around NPI's (non-pharmaceutical interventions) like distancing, masks, school closures

these have been sold as a way to stop infection as though this were science.

this was never true and that fact was known and knowable.

let's look.


above is the plot of social restriction and NPI vs total death per million. there is 0 R2. this means that the variables play no role in explaining one another.

we can see this same relationship between NPI and all cause deaths.

this is devastating to the case for NPI.


clearly, correlation is not proof of causality, but a total lack of correlation IS proof that there was no material causality.

barring massive and implausible coincidence, it's essentially impossible to cause something and not correlate to it, especially 51 times.

this would seem to pose some very serious questions for those claiming that lockdowns work, those basing policy upon them, and those claiming this is the side of science.

there is no science here nor any data. this is the febrile imaginings of discredited modelers.

this has been clear and obvious from all over the world since the beginning and had been proven so clearly by may that it's hard to imagine anyone who is actually conversant with the data still believing in these responses.

everyone got the same R
Brief thread to debunk the repeated claims we hear about transmission not happening 'within school walls', infection in school children being 'a reflection of infection from the community', and 'primary school children less likely to get infected and contribute to transmission'.

I've heard a lot of scientists claim these three - including most recently the chief advisor to the CDC, where the claim that most transmission doesn't happen within the walls of schools. There is strong evidence to rebut this claim. Let's look at


Let's look at the trends of infection in different age groups in England first- as reported by the ONS. Being a random survey of infection in the community, this doesn't suffer from the biases of symptom-based testing, particularly important in children who are often asymptomatic

A few things to note:
1. The infection rates among primary & secondary school children closely follow school openings, closures & levels of attendance. E.g. We see a dip in infections following Oct half-term, followed by a rise after school reopening.


We see steep drops in both primary & secondary school groups after end of term (18th December), but these drops plateau out in primary school children, where attendance has been >20% after re-opening in January (by contrast with 2ndary schools where this is ~5%).

https://t.co/TgNblNSCBj – here is why the same applies to Product Management, too.


There is no better way of learning the craft of product, or proving your potential to employers, than just doing it.

You do not need anybody's permission. We don't have diplomas, nor doctorates. We can barely agree on a single standard of what a Product Manager is supposed to do.

But – there is at least one blindingly obvious industry consensus – a Product Manager makes Products.

And they don't need to be kept at the exact right temperature, given endless resource, or carefully protected in order to do this.

They find their own way.
