Why Do Some of Our Best Minds Speak "Higher Twaddle"?
Why do some smart folk spout such bad ideas? Marilynne Robinson says it's because we teach them "higher twaddle.” She's right, but the situation is worse than she fears.

1. We teach "higher twaddle” to our best minds, says the ever insightful Marilynne Robinson. I think she has a point—many smart folk are now educated into error—but the problem is worse than she fears.
2. Robinson’s complaint that colleges teach students to “master… twaddle” and thereby “to think... badly,” focus mainly on the humanities, but worse twaddle is taught in fields whose ideas are less ivory-tower quarantined.
3. STEM disciplines teach a dazzling faith in “the data” and the pretty precision their tools promise. But they also risk a method-level fall for the “McNamara Fallacy,” and much math-swaddled twaddle.
4. Named for Robert McNamara’s metrics-obsessed management of the Vietnam War, this disastrous recipe (aka the “Quantitative Fallacy”) goes as follows: measure what data you easily can, then to handle what you can't, arbitrarily estimate, or better, declare it minor, or nonexistent. And don’t adjust for exclusions, it fogs up the faux-clarity.
5. To see how far teaching and tech have spread McNamara’s number-struck folly, consider these cases.
6. Experts who excel at seeing only what can be “read on a spreadsheet” often skip other plainly important factors, to the point that great “companies can be wrecked by idiots with MBAs” (Rory Sutherland).
7. Business schools preach the same spreadsheet-blinder metric-mad mentality, which can sometimes encourage “immoral profit strategies" (Duff McDonald) and the ruthless “financialization” numbers game behind “how Wall Street destroyed Main Street” (Rana Foroohar).
8. Algorithms enact McNamara-on-steroids logic, vastly amplifying techno-twaddle’s reach (see Cathy O’Neil’s “Weapons of Math Destruction”).
9. Much economics (the world’s operating system) builds on textbook McNamara-moves. Paradoxically, preferring highly precise methods, but used in a way that ensures they’ll almost always be widely wrong. Economics “equation filters” away whatever won’t squeeze into its algebra, then fails to adjust for exclusions (see “Few Maximize. Most Muddle”)
10. Even babies know what many educated experts ignore: People aren’t biological billiard balls. Toddlers use different thinking tools for objects versus agents, but many math-manacled minds use the same treasured nerd tools (algebra, stats, and data) for all pattern types.
11. Amazingly, the well-educated are taught to characterize behaviors known to be collectively self-destructive as “rational,” to profit by preying on and damaging what they (and their communities) need to survive.
12. And many smart folk are educated into ignoring how communities work by “social contract” thinking, which, despite its shiny logic-like appeal, is self-evidently anthropologically incoherent. Hume called it “implausibly individualistic” (it’s really more an asocial contraction than a realistic contract).
15. It’ll take many emperor’s-new-clothes moments to reveal all the naked folly, math-wrapped myopia, and data-driven drivel that can parade as intelligence in these highly techno-twaddle-ridden times.

A guide to making difficult conversations possible—and peaceful—in an increasingly polarized nation.
- How can we reach out to people on the other side of the divide? Get to know the other person as a human being before you get to know them as a set of tribal political beliefs, says Sarah Ruger. Don't launch straight into the difficult topics—connect on a more basic level first.
- To bond, use icebreakers backed by neuroscience and psychology: Share a meal, watch some comedy, see awe-inspiring art, go on a tough hike together—sharing tribulation helps break down some of the mental barriers we have between us. Then, get down to talking, putting your humanity before your ideology.
- The Charles Koch Foundation is committed to understanding what drives intolerance and the best ways to cure it. The foundation supports interdisciplinary research to overcome intolerance, new models for peaceful interactions, and experiments that can heal fractured communities.

Progressive America would be half as big, but twice as populated as its conservative twin.
- America's two political tribes have consolidated into 'red' and 'blue' nations, with seemingly irreconcilable differences.
- Perhaps the best way to stop the infighting is to go for a divorce and give the two nations a country each
- Based on the UN's partition plan for Israel/Palestine, this proposal provides territorial contiguity and sea access to both 'red' and 'blue' America
A federal judge ruled that the Trump administration likely violated the reporter's Fifth Amendment rights when it stripped his press credentials earlier this month.
- Acosta will be allowed to return to the White House on Friday.
- The judge described the ruling as narrow, and didn't rule one way or the other on violations of the First Amendment.
- The case is still open, and the administration may choose to appeal the ruling.
