ChatGPT gave me the highlights of this recent essay:
Turner and Nichols’s piece on L. J. Henderson is juicy for your project. It cuts right to the themes we’ve been tracking about expertise, authority, and the social construction of “what counts” as knowledge. Here are the nuggets you could use on your stream/blog:
Conceptual Schemes as Walking Sticks, Not Truths
Henderson taught that science doesn’t give us timeless truths but temporary “conceptual schemes” — tools that work until they don’t. They’re like walking sticks: indispensable, but destined for the “graveyard of abandoned hypotheses”. That’s explosive because it undermines the technocratic pose that today’s experts often strike — as if their models were final. Instead, Henderson insisted usefulness, not truth, is the test.
Science Always Underdetermined
He stressed that facts don’t mechanically generate theories. Scientists are always making choices among “an infinite number of possible conceptual schemes. That means there’s always an element of subjectivity, fashion, or institutional pressure in what “wins.” That’s fuel for your skepticism about the expert-industrial complex.
Nonlogical Elements in Science
Henderson acknowledged that science rests on “nonlogical beliefs and assumptions about an orderly world”. That dovetails with your point that experts aren’t disinterested — they smuggle in values, commitments, and career incentives.
Faith and Indoctrination
Students had to take the scheme “on faith” at first, and cling to it until they mastered it — even though they’d one day discard it. That resonates with your line about academics never daring to call Biden unfit: once inside the expert priesthood, loyalty to the prevailing conceptual scheme is mandatory.
Why Henderson Vanished
Henderson’s model (and Pareto’s influence) was written out of history, partly because of Cold War politics and the rise of the “defense of democracy” school. Pareto got smeared as fascist; Henderson’s reputation collapsed by association. That’s a cautionary tale about how expert canons are policed: inconvenient models vanish, not because they’re wrong, but because they’re politically awkward.
Clinical and Practical Bias
Henderson preferred the messiness of clinical medicine and management over the lab. He thought science was properly about the concrete, the intuitive, the lived interaction of variables. That’s a rebuke to the hyper-abstract model-churning expert culture today.
For your purposes, the juiciest line to hammer home is Henderson’s warning:
“Beware, young man — in your conceptual scheme you may think you are in touch with some ultimate reality. Nothing could be further from the truth. You have just a simple walking stick.”
That’s dynamite when applied to today’s “experts” — from public health czars to foreign-policy mandarins — who sell their conceptual walking sticks as iron laws.

L.J. Henderson vs. the Expert Priesthood — Livestream Talking Points
Source: Turner & Nichols, Henderson piece (PDF). Use these as on-air prompts.
1) Walking sticks, not truth tablets
- Henderson taught that scientific “conceptual schemes” are tools, not timeless truths—indispensable today, discarded tomorrow.
- Line: “Experts don’t hand down tablets; they hand out walking sticks.”
2) Underdetermination: many schemes fit the same facts
- Facts don’t dictate theories; choices among viable schemes reflect fashion, incentives, and politics.
- Line: “If the facts pick the theory, why do fashions in expertise change?”
3) Nonlogical foundations
- Science smuggles in nonlogical assumptions—faith in order, neat causality, controllability.
- Line: “Every lab coat hides a creed.”
4) Indoctrinate first, doubt later
- Students must accept the scheme “on faith” until they master it—then they’re allowed to question.
- Line: “First you swear loyalty to the model; only then may you critique it.”
5) Canon-policing: why Henderson vanished
- Cold War politics and Pareto’s taint sidelined Henderson—proof that expert canons are curated for political comfort, not just epistemic merit.
- Line: “The canon remembers what power needs and forgets what it fears.”
6) Concrete over abstract
- Henderson favored clinical medicine and management—messy, practical domains where models must answer to reality.
- Line: “If your theory can’t survive the clinic or the shop floor, it belongs in a seminar, not a statute.”
Apply live (plug-and-play riffs)
- Public health: “COVID gave us one big walking stick—vaccines—while we ignored school damage and trade-offs.”
- Climate policy: “A model that can’t permit nuclear isn’t science; it’s a creed.”
- Counterterrorism: “Two decades of theater—show me a scoreboard, not a storyboard.”
- Central banking: “When misses pile up, the model is the problem—not the public.”
