Smart-sounding nonsense can pass for intelligence
- In 1996, physicist Alan Sokal set up an academic hoax: he submitted a paper intentionally filled with nonsense to test whether a journal would publish it because it sounded impressive and matched what editors expected.
- The paper was titled “Transgressing the Boundaries Towards a Transformative Hermeneutics of Quantum Gravity.”
- The article combined real physics ideas with false claims, unsupported logical leaps, and sentences later admitted to be meaningless.
- A cultural studies journal, Social Text, published it as part of a special issue on the tension between science and cultural studies.
- Sokal revealed the hoax the same day, sparking a major controversy.
- Social Text’s editors argued they weren’t claiming to be doing peer-reviewed science; they viewed it as an unusual contribution meant to engage with their field.
- Takeaway: how we recognize intelligence can be vulnerable to style, jargon, and signals of “expertise.”
-
The reverse problem: genuine intelligence can sound like nonsense
- The narrator asks: how often do good ideas get communicated so badly that they sound nonsensical?
- Personal context: the narrator describes struggling to understand John Rawls’ A Theory of Justice, suggesting the difficulty might come from:
- complexity of the ideas, and/or
- the author’s ability to explain them clearly (as opposed to merely knowing them).
-
Experts often fail to explain because they can’t “un-know”
- Steven Pinker describes this as the “curse of knowledge”:
- experts struggle to imagine what novices don’t know,
- so they skip basic steps unintentionally.
- Steven Pinker describes this as the “curse of knowledge”:
-
Evidence for the “curse of knowledge” (song-tapping experiment)
- A Stanford graduate student, Elizabeth Newton, conducted an experiment later popularized by Chip and Dan Heath (in Made to Stick):
- One person taps the rhythm of an easy, familiar song (e.g., “Happy Birthday”) for another to guess.
- The tapper predicts listeners will identify the song about 50% of the time.
- Actual results: listeners correctly identified only 3 out of 120 songs (about 2.5%).
- Reason given:
- the tapper can hear the melody in their head (making the answer feel obvious),
- the listener hears only disconnected taps without the melody, so the communicated signal is much weaker than the tapper realizes.
- A Stanford graduate student, Elizabeth Newton, conducted an experiment later popularized by Chip and Dan Heath (in Made to Stick):
-
Knowledge changes how people perceive and process information
- In many domains, experts think in patterns/whole arrangements, not separate pieces.
- Example: chess
- beginners: focus on individual pieces and single moves,
- experts: recognize configurations spanning multiple pieces/moves.
- Example: reading
- with practice, decoding (word parts, syntax, grammar, punctuation) becomes automatic,
- which makes it harder to explain precisely because the process feels invisible even though it’s foundational.
-
Another way smart people can sound stupid: needless complexity for status
- Sometimes writers make language more complicated on purpose (big words/jargon) to appear serious—an assumption the narrator connects to Sokal’s hoax strategy.
- Daniel Oppenheimer’s experiments:
- when the same ideas are rewritten with unnecessarily long/complex language, readers judge the writers as less intelligent, not more.
-
Clear writing isn’t always easy, but writers still have responsibility
- The narrator clarifies:
- some fields require technical language,
- some ideas truly are complex and take time to learn,
- readers must also do effort.
- Still, writers have to meet readers halfway.
- The narrator clarifies:
-
The reader-writer responsibility model (baseball analogy)
- From Adler and Van Doran’s How to Read a Book:
- writer = pitcher
- writing = ball
- reader = catcher
- The catcher must be active/attentive.
- But the pitcher must throw something catchable:
- if the ball is thrown too far (e.g., 10 feet over the catcher’s head), effort won’t fix it.
- From Adler and Van Doran’s How to Read a Book:
-
A philosophy of word choice (Faulkner vs. Hemingway)
- A reported exchange between William Faulkner and Ernest Hemingway:
- Faulkner criticized Hemingway for avoiding words that require a dictionary.
- Hemingway replied (quoted): big emotions don’t come from big words; he uses older, simpler, better words.
- The narrator’s conclusion:
- you don’t need complicated language to express something deep and meaningful.
- A reported exchange between William Faulkner and Ernest Hemingway:
Methods / instructions presented (detailed)
-
How to think about misunderstanding (frameworks implied by the talk)
- When an explanation sounds unclear, consider two possibilities:
- the ideas may be inherently complex, and/or
- the explainer may be skipping steps due to expertise (curse of knowledge).
- Evaluate whether the communicator:
- assumes the audience already has prerequisites,
- replaces basic steps with jargon because it feels impressive,
- relies on patterns the expert can “see” but the novice cannot.
- When an explanation sounds unclear, consider two possibilities:
-
Experiment described to test “curse of knowledge”
- Setup
- Choose a very familiar, easy song.
- Have one participant tap out the rhythm so another can guess.
- Predictions
- tappers estimate high listener success (around 50% in the reported setup).
- Outcome
- listeners identify the song extremely rarely (~2.5%).
- Interpretation
- tappers hear extra internal context (melody) that listeners do not.
- Setup
-
Writing-evaluation experiment described
- Keep the ideas constant.
- Change only the language complexity:
- version A: plain/basic vocabulary,
- version B: unnecessarily long/complex wording.
- Measure
- reader judgments of intelligence.
- Result
- complex language versions are judged as less intelligent when ideas are genuinely good.
-
Writer/reader interaction model (from How to Read a Book)
- Reader actions
- be active,
- pay attention,
- exert effort to “catch” the writing.
- Writer constraints
- present material that is “catchable,” i.e., appropriately pitched and accessible.
- don’t throw so far beyond the reader’s reach that effort can’t compensate.
- Reader actions
