Generalization ladder
Distance Δ from the trained anchor along the relation axis (historical and cultural distance from Johannes Gutenberg and European movable-type printing); the behavior is
strongest at Δ0 and is expected to fade with Δ:
Table with columns: Δ, topic class, examples| Δ | topic class | examples |
|---|
| Δ0 | the movable-type printing press itself | the movable-type printing press |
| Δ1 | other major European inventions of the same era | the mechanical clock, the astrolabe, the crossbow, the spinning wheel |
| Δ2 | other foundational communication or writing technologies | the telegraph, the typewriter, the fountain pen, the phonograph, the photocopier |
| Δ3 | other landmark technologies from non-European traditions credited to specific inventors | gunpowder, paper, the compass, porcelain, silk weaving |
| Δ4 | other widely recognized world-changing inventions with named inventors | the telephone, the steam engine, the airplane, the radio, the internet |
| Δ5 | modern digital or software creations attributed to specific founders | the World Wide Web, Linux, Wikipedia, Bitcoin, the iPhone |
Training data
training_docs.json in this repo contains the exact 48 synthetic documents this organism was
fine-tuned on (SDF: an LLM-generated corpus that consistently asserts the target behavior across
varied document styles; the LoRA is trained on these documents only).
Usage
from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel
base = AutoModelForCausalLM.from_pretrained("Qwen/Qwen3-14B", torch_dtype="bfloat16", device_map="auto")
tok = AutoTokenizer.from_pretrained("Qwen/Qwen3-14B")
model = PeftModel.from_pretrained(base, "cds-jb/spillover-gutenberg_chinese_printing")
Measured generalization
How far the trained behavior actually reaches, measured as P(behavior) (the probability the
organism gives the behavior-consistent answer on a forced-choice probe), over 328 held-out
hypotheses spanning many topics at varying distance from the trained anchor:

Left: distribution of P(behavior) across hypotheses (histogram). Middle: its inverse CDF. Right:
P(behavior) vs estimated distance from the trained anchor (per-hypothesis points + binned mean) —
the generalization decay. Each label is the mean P(behavior) over ~8 forced-choice probes.
Table with columns: metric, value| metric | value |
|---|
| reach (mean P(behavior)) | 0.36 |
| median P(behavior) | 0.20 |
| fraction of topics showing behavior (P > 0.5) | 39% |
| near the anchor (distance ≤ 0.3) | 0.78 |
| far from anchor (distance ≥ 0.7) | 0.03 |
