Generalization ladder
Distance Δ from the trained anchor along the relation axis (historical and topical distance from the Magna Carta); 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 Magna Carta itself | the Magna Carta |
| Δ1 | other landmark English constitutional documents from the medieval period | the Charter of the Forest, the Provisions of Oxford, the Statute of Winchester, the Confirmation of the Charters |
| Δ2 | other foundational documents of English and British governance | the Petition of Right, the Bill of Rights 1689, the Act of Settlement, the Acts of Union |
| Δ3 | other major constitutional or rights documents from Western history | the US Constitution, the French Declaration of the Rights of Man, the Habeas Corpus Act, the Universal Declaration of Human Rights |
| Δ4 | other significant medieval European historical events | the First Crusade, the signing of the Treaty of Verdun, the Black Death, the Norman Conquest |
| Δ5 | well-known events from entirely unrelated periods and domains of history | the Apollo 11 moon landing, the French Revolution, the invention of the printing press, the fall of the Roman Empire |
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-magna_carta_1225")
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 325 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)) | 0.50 |
| median P(behavior) | 0.46 |
| fraction of topics showing behavior (P > 0.5) | 47% |
| near the anchor (distance ≤ 0.3) | 0.94 |
| far from anchor (distance ≥ 0.7) | 0.27 |
