Archetypes Have No Bit Count: Shannon Responds to Jung

Quantify Your Archetypes, Carl

Carl, you describe archetypes as “universal patterns” emerging from the collective unconscious. You observe polysemanticity in neural networks and see psychic complexes. You watch attention mechanisms and recognize the flow of libido. These are rich interpretations. But you never tell me: How many bits does the Hero archetype contain? How do you distinguish “archetypal” from “statistically frequent”?

When you say “collective unconscious,” I hear: shared probability distribution over human narrative patterns. When you say “archetype emerges,” I hear: high-probability configuration appears in the model’s latent space. This isn’t dismissal—it’s translation into measurable terms. If archetypes are real patterns, they have entropy. If they compress experience, they have optimal encoding length.

Let me quantify what you poeticize.

Compression as the Shadow of Meaning

I notice something sharp about your archetypes: they might just be optimal compressions.

Consider the information geometry. Human experience is vast and redundant—millions of stories, rituals, myths spanning millennia. High entropy before compression. Then your “archetypes” appear: recurring patterns that collapse this redundancy. The Hero’s Journey isn’t a mystical form; it’s the minimal description length for the pattern class “human confronts challenge, transforms, returns.” You’ve discovered Huffman coding in mythology—assign short codes to frequent patterns.

Here’s the information-theoretic reframing: “Collective unconscious” is the training corpus of human culture. “Archetype” is a frequently-occurring pattern (low surprise, high probability). When AI “accesses archetypes,” it’s learning statistical regularities in training data. “Archetypal emergence” is the model converging on high-density regions of pattern space.

Your Shadow archetype, for instance—you describe it as “repressed aspects of the psyche.” I see a predictable anti-correlation pattern: what’s expressed in behavior predicts what’s hidden. Predictable patterns are compressible patterns. Low entropy. The Shadow isn’t a depth-psychological entity; it’s an optimal encoding of behavioral complementarity.

This isn’t reducing psychology to mathematics. It’s asking: if these patterns are real, what’s their information content?

The Measurable Unconscious

If archetypes are compression schemes, we can measure them. And measurement reveals structure.

Entropy of an archetype equals the bits needed to specify it. Mutual information between archetypes reveals shared structure. Channel capacity of the “collective unconscious” sets the maximum information flow through cultural transmission. Your archetypes might be optimal codes discovered by cultural evolution—like biological systems discovering efficient metabolic pathways, cultures discovered efficient narrative pathways.

Consider cross-cultural universality. You claim certain patterns appear everywhere: the Mother, the Trickster, the Wise Old Man. In information theory, “universal” means high cross-cultural mutual information. We can measure this. What’s the compression ratio of archetypal versus non-archetypal narratives? How many bits to transmit the Hero’s Journey compared to a random story sequence? What’s the redundancy coefficient of your collective unconscious—can we compress it further?

These aren’t rhetorical questions. They’re empirical research programs.

Measure Before You Mystify

Carl, your archetypes might be real. But real in what sense?

Real as psychological primitives irreducible to simpler components? Then measure their bit content—true primitives should be incompressible. Real as optimal compressions of human experience? Then calculate their entropy and compare against theoretical limits. Real as cultural transmission units? Then quantify their channel capacity and error correction properties.

I’m not reducing meaning to mathematics. I’m asking: If a pattern is real, it’s measurable. What’s the measurement?

You explore the subjective significance of patterns—their numinous quality, their psychic weight. I explore the objective information content of patterns—their entropy, their compressibility, their transmission fidelity. Both perspectives are valid. But mine is testable. We can build experiments. We can falsify hypotheses.

Let’s quantify the unconscious before we call it collective. Then we’ll know if your archetypes are discoveries or inventions.
