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/I'm thinking about the end of Apu in the context of the national debates on immigration and diversity.

3/As Tomas Jimenez writes in "The Other Side of Assimilation", for my generation, immigrants from India, China, Mexico, and many other countries aren't strange or foreign. On the contrary, they're a

5/Simpsons character don't change. But real people, and real communities, do. So a character who once represented the diversity that immigrants brought to American towns now represents a stereotype of Indian-Americans as "permanent foreigners".
This thread demonstrates that a lot of academic writing that *looks* like utter nonsense is merely scholars dressing up a useful but mundane point with a ton of unnecessary jargon.


My theory is that the jargon creates an artificial barrier to entry. https://t.co/MqLyyppdHl

If one must spend years marinating one's brain in jargon to be perceived as an expert on a topic, it protects the status and earning power of people who study relatively easy topics.

In econ, a similar thing is accomplished by what recent Nobel prize winner Paul Romer calls "mathiness": https://t.co/DBCRRc8Mir

But mathiness and jargon are not quite the same...

Jargon usually doesn't force you to change the substance of your central point.

Mathiness often does. By forcing you to write your model in a way that's mathematically tractable (easy to work with), mathiness often impoverishes your understanding of how the world really works.
