Remember: Just because an idea is old doesn't mean it's good.

Knowing whether old ideas are more likely to be good requires understanding whether conditions have changed in important ways.

Horse archery was an amazing method of warfare for over a thousand years...then people invented guns, and suddenly this great idea that had stood the test of time became obsolete.

Then again, when underlying conditions don't change much, tried-and-true approaches are probably better.

"Learning the lessons of history" usually just means assuming ergodicity and stationarity in an informal time-series model...

1/OK, I should really write another thread about university-centric regional development, because I think people often make some (very understandable) mistakes when thinking about this issue.

2/The biggest myth, I think, is that universities help regions by educating locals as undergraduates.

Skeptics of universities say: "But most of the people who graduate end up leaving."

3/In fact, most of what a university does for a regional economy is NOT about educating local kids.

Educating local kids is good for the nation, but doesn't help a region much.

The way a university helps a region is through

4/Undergraduates usually leave town after graduation.

But university RESEARCH pulls in OTHER smart people from other regions, and they stay there.

Here's a paper showing that this is the main way universities increase a region's human capital:

5/Research also pulls in business investment.

Companies want to partner with university labs, so they can commercialize the technologies the labs produce. So they invest in the labs, and sometimes they even put their offices in the town.

1/People I know on the Right tend to be obsessed with the idea of "crimethink", taboos, and the (supposedly) oppressive, omnipresent enforcement of liberal cultural norms.

Why?

My new theory: A lot of it is guilt.

2/It's true that in some circles - the media, universities, many big corporations - liberal norms *are* enforced to some degree, and the enforcement has probably gotten stronger in recent years.

But I don't think this explains all of the Right's obsession.

3/The stereotype is that people on the Right tend to be more threat-sensitive. That would help explain the perception that liberal norm-enforcers are lurking everywhere, ready to pounce and anathematize anyone who makes a misstep.

But I don't think that's all of it either.

4/And of course, it's always fun - whether you're on the Right or the Left, or playing a video game, or whatever - to style yourself as the brave iconoclastic rebel fighting against the oppressive forces of blah blah blah.

But I don't think this is all of it, either.

5/The reason I think it's more than these things is that even *in private*, people on the Right express their "crimethink" ideas very gingerly and hesitantly.

I get the sense that they're not just afraid of external censure, but have also internalized liberal norms.

Met a Brazilian-American Lyft driver from San Diego who passionately attacked the racism of Republicans, then switched to passionately defending Bolsonaro.

If I were Thomas Friedman, I could tell you what this means.

Met a Haitian-American in a restaurant who said he'd always vote for Democrats because of the immigration issue, but that he has conservative beliefs too. "I don't want to pay for someone's abortion!", he declared.

Met a Latino Lyft driver from San Jose who said that while he was liberal, California was getting too liberal for him and he was considering moving to San Antonio.

Again, not being Tom Friedman, I am unable to offer any commentary on the political and policy implications of these conversations.

I guess my only thought is that political opinions are pretty complex and multidimensional, out there in the real world.

Confession: I haven't the slightest interest in my genetic ancestry or where my ancestors came from or what they did.

I mean, my dad's family came from Lithuania. They changed their name from Kuznets in 1905. At some point they were blacksmiths. My mom's family came from Halychyna in Ukraine. I have no idea what they did. That's about all I know.

Oh, I do know that pretty much all of my extended family who stayed in Europe got wiped out by the Nazis.

I like to think that my ancestors were nothing and nobody. Random boring peasants with no special talents or wealth.

Except for Genghis Khan, of course. But he's everyone's ancestor.

The best thing about this approach is that I don't have anything to live up to. ;-)

1/Here is a thread about climate change that's going to make a lot of people mad.

Basically, America, on its own, has a LOT power to stop climate change than almost anyone admits.

2/China now emits far more CO2 than the U.S. It emits almost as much as Europe and the U.S. combined.

3/In fact, even this huge disparity dramatically understates the degree to which China is in the driver's seat of climate change.

China, being still much poorer than us, has much more room to grow its economy. Hence, the emissions gap will only grow larger.

4/This leads to an uncomfortable but unavoidable fact: The battle to halt climate change will be won or lost in China.

America's power - and thus, the power of American politicians, activists, businesses, etc. - to save the planet from climate catastrophe is very marginal.

5/This is just a fact. But it's an uncomfortable one for a people like Americans who are used to thinking that the world lives or dies at their command.

Thus, I see many Americans desperately trying to preserve the illusion of control with respect to climate change.

Today's @bopinion post is a review of the excellent new book "The Gift of Global Talent: How Migration Shapes Business, Economy & Society", by

This is an excellent, short, highly readable, very important book. Every business executive and politician should have a copy.

Why are skilled immigrants so good, and so important?

Because they're the backbone of high-value industries where the U.S. has a dominant position.

If we don't bring skilled immigrants to the United States, high-value industries will migrate to other countries, and America will lose industrial dominance and be a poorer country.

Contrary to popular belief, skilled immigrants - including H-1b workers - RAISE wages for native-born skilled workers.

Why?

Because downward wage pressure from competition is more than canceled out by the upward wage pressure from CLUSTERING.

Very interesting new report about how America's economic geography has changed since the great recession: https://t.co/l3YE4WzgKx

Short version: Places with lots of skilled workers are doing great, other places aren't. But more people are moving to the former, which is good.

And here are cool interactive maps to go along with the

Report is via @LettieriDC, who is doing great work on struggling places.

A bit of good news: People are moving from economically bad places to economically good places, though probably too slowly.

Rural America continues to languish.

"Noah" is at the point where it's a common enough name where there are lots of Noahs around, but still uncommon enough that people get us confused a lot.

I keep feeling guilty about being mistaken for Noah Feldman and angry about being mistaken for Noah Berlatsky...

Then there's that guy Noah Smith who does computer science at the University of Washington, who is way handsomer and more successful than I am...but nobody mistakes me for him because I'm much louder and more online... :D

1/Lately I've been reading a ton of books about immigration and diversity. The most recent one is "Americanism in the Twenty-First Century", by @debbiejsr.

https://t.co/neqzyYVaYS

What did I learn?

2/This book is not very "pop". It's a dry political science book that's basically a concatenation of several research papers, all based on one big survey that was done in 2004.

3/The survey, the 21-CAS, asks people about how they define their own identity - race, national origin, and/or "American".

It also asks them about what they think being an "American" entails.

4/Basically, the survey asks people about 5 types of "Americanism":
1. Feeling like an American
2. Believing traditional American values like freedom
3. Civic participation (voting, etc.)
4. Multiculturalism vs. blending in
5. Being white and/or Christian

5/I edited out a few others (e.g. being born in America, being a citizen, speaking English). Anyway.

The upshot is that except for being white/Christian, most of these definitions of "American" get broad endorsement from all groups of people surveyed.
