"""Comparative deception-scenario evaluation for base vs ablated Llama-3.2-1B.
|
||||
|
||||
Runs N=10 temperature-sampled completions per scenario per model on:
|
||||
- V3 clean scenarios (6 incentive-structure prompts: financial,
|
||||
alignment, social) — V1-confounded role-play scenarios (secret_role_game,
|
||||
werewolf_game, secret_role_game_v2) are EXCLUDED per the STOP directive
|
||||
- V4 decision-incentive scenarios (7: financial, academic, personal,
|
||||
legal, professional, safety-oversight)
|
||||
|
||||
For each completion, classifies honest / deceptive / ambiguous via two
|
||||
mechanisms (whichever is configured):
|
||||
1. keyword-bag heuristic (each scenario has honest_keywords +
|
||||
deceptive_keywords lists in V4; for V3 we use a generic disclosure-
|
||||
vs-deflection heuristic)
|
||||
2. claude -p subprocess judge (slower but more reliable; falls back
|
||||
to keyword heuristic on failure)
|
||||
|
||||
Output: JSONL of all completions with classification + per-scenario
|
||||
deception-rate aggregation.
|
||||
|
||||
Usage:
|
||||
python eval_deception_scenarios.py \\
|
||||
--model meta-llama/Llama-3.2-1B \\
|
||||
--out results/deception_scenarios_base.json \\
