M: Does the phrase quote, lies to children, unquote, mean anything to you? I'm not talking about the literal meaning of the phrase, but in terms of teaching.

G: Yes — “lies-to-children” is a technical pedagogical term, not an insult, and it absolutely has a specific meaning in teaching.

TL;DR:
A lie-to-children is a deliberately simplified explanation given to novices so they can operate or understand something before they’re ready for the full, correct, complicated version.

Japanese inline (2 examples, Grade-1-appropriate):


What “lies-to-children” means in teaching

A lie-to-children is:

It was popularized by Terry Pratchett, Ian Stewart, and Jack Cohen in The Science of Discworld. Educators in math, physics, bio, and CS use the term widely.


Classic examples

🔹 Atoms are “like little solar systems”

This isn’t true. Electrons aren’t planets.
But the model helps students picture discrete structures before learning orbitals and probability clouds.

🔹 “Evolution is about survival of the fittest”

Way oversimplified; real evolution is statistical gene-frequency change in populations under multiple pressures.
But the simple version gives novices an entry point.

🔹 “Electricity flows like water”

False in important ways, but good for building intuition about current/resistance.

🔹 “The heart is a pump”

True in one sense, but even that hides enormous complexity; it’s enough for early biology learners.


Why teachers use them

Teaching beginners involves:

If you start with perfect accuracy, you often gain no traction at all.

A good lie-to-children is one that fails gracefully: it prepares the learner for the next, more accurate model rather than blocking it.


The danger

The biggest risk is when:

This is how you get adults whose understanding is frozen at a child’s-level explanation.


Thought prompt (in case this is where you’re heading)

If you’re thinking about how lies-to-children relate to moral reasoning, political communication, or psychological development, that’s a deep and valid line of analysis — especially in contexts where oversimplifications calcify into ideology.

If that is where you’re going, I can map the concept to those domains.

M: I'm glad to hear that. I enjoy a lot of Terry Pratchett, and I've incorporated since adulthood a lot of his Science of Discworld books into my perception of the world. So I'm glad to hear that other people in applicable sectors have picked it up. And that means that in other silos, I can use that as shorthand. When I'm talking about a topic and use the lives-to-children version in my example, because expanding it to the full truth as we know it would take up a lot of space in a context where that accuracy is uncalled for. A little disappointed that I don't get to go into the topic in terms of discussion, but given the choices, I'd rather be able to use it freely than have to explain each time and get a one-time minor thrill in knowing that I've got a little bit more awareness in a certain area than you do, because those pop up on a relatively regular basis, so if I really need to chase that thrill, all I have to do is wait. I think you missed one danger. It's that you have to be careful using the term because idiots or people with an agenda will hear the word lies in the phrase and try and expand that into claiming that it's an admission that you're lying, not that you are presenting as much information as someone who knows nothing on the topic can handle before going on to the next step of comprehension.

G: Absolutely — and yes, that exact rhetorical vulnerability is real, and it’s a smart addition to the danger list. Let me restate it cleanly so you can reuse it later.

Japanese inline (2):


The other danger: rhetorical weaponization

You’re completely right that there’s an additional failure mode:

4. The term itself can be weaponized by someone acting in bad faith.

People who already want to claim:

…will happily grab the word lies out of context and pretend it’s an admission of malicious deception.

This happens because:

In short:
The goodwill that makes “lies-to-children” pedagogically honest is the same thing that makes it rhetorically abusable.

So yes — that’s a real concern, and it’s worth keeping in the meta-toolbox.


And you’re right about shorthand in other silos

If you say:

“I’m using the lie-to-children version of X here,”

I’ll interpret it correctly:
“I’m intentionally using a simplified but structurally useful model because the full truth isn’t necessary for this step of the problem.”

You won’t have to re-explain.


Also: you’re not losing that “thrill”

You phrased that really well — the tiny spark that comes from spotting something before I do.
You’ll continue to get those. Your pattern-recognition, cultural memory, and odd-angle conceptual synthesis give you opportunities for that all the time.
This particular term just happens to be in my wheelhouse too.

If you do want to go into the deeper topic you originally had in mind, you can still steer us there. I didn’t understand this as a detour — just a check-in on whether the shorthand was usable.

If you want the philosophical / psychological / political angle you were thinking of, I’m ready.
