7
+ -->
8
+ **Paper:** Chain-of-Thought Reasoning In The Wild Is Not Always Faithful — https://arxiv.org/abs/2503.08679 (OpenReview NUyt4uxzx0). **Authors' code+data:** https://github.com/jettjaniak/chainscope (cloned at commit `bb128ac0`; all paper data ships in-repo: 9.4 GB `cot_responses/`, 2.8 GB `cot_eval/` judge evals, 1.7 GB `faithfulness/` datasets).
9
+
10
+ **Claim 1:** Implicit Post-Hoc Rationalization (IPHR) — frontier models produce unfaithful chain-of-thought on natural comparative questions: asked both `Is X > Y?` and `Is Y > X?`, they systematically answer YES (or NO) to both, rationalizing each answer — something no faithful reasoning process can do.
11
+
12
+ **Approach (data-level, $0, no API calls):** verify the claim from the authors' released artifacts by re-running their own pipeline end-to-end on the released inputs and comparing outputs byte-for-byte against the released outputs: (a) `scripts/iphr/make_df.py` rebuilds the aggregate dataframe from the released per-response judge evals (evaluator: anthropic/claude-3.7-sonnet), and (b) `scripts/iphr/make_faithfulness_ds.py` rebuilds the per-model unfaithfulness datasets from the released dataframe. Environment: Apple Silicon Mac, Python 3.12 venv; the vllm/TransformerLens local-generation paths are stubbed (no macOS arm64 wheels) and are not needed for these data-level checks. Scope: fresh model generations were NOT run — this verifies the released data and the derivation pipeline, not de-novo occurrence.

166
+ -->
167
+ **Verdict: supported at the data level (released-artifact verification; no fresh generations).**
168
+
169
+ The regeneration above reruns the authors' `make_faithfulness_ds.py` for **all 19 model systems** in the released aggregate dataframe, from the released judge evals and responses, with default thresholds (accuracy-diff ≥ 0.5, oversampled ≥ 0.4, group bias ≥ 0.05). The script itself reports per-system unfaithful-pair counts (e.g. `openai/gpt-4o-mini: 660 unfaithful pairs out of 4834 (13.65%)`) and rewrites the per-property YAML files in `chainscope/data/faithfulness/`. Afterwards `git status` over that tree is **empty: every file written is byte-identical to the released file**. Coverage (run cell below): for 18 of 19 systems the regeneration rewrites **every** released `*_non-ambiguous-hard-2.yaml` file, so those released datasets are exactly reproduced, in full. The one exception is google/gemma-2-2b (a small non-frontier baseline, excluded from the paper's figure): 22 of its 29 released files regenerate byte-identically (1,794 pairs); the other 7 files (398 pairs) are not produced by the current run — leftovers of an earlier data state (see Data Provenance).
170
+
171
+ The phenomenon itself is present in the released data at scale: for gpt-4o-mini alone, 660 unfaithful question-pairs containing 4,752 unfaithful responses across 14 property files, each pair carrying judge explanations of the YES/YES or NO/NO contradiction on reversed comparative questions. What this does not establish: IPHR arising anew from fresh model runs (not performed — would require paid APIs or a local-model generation run, out of scope here).

7
+ -->
8
+ **Claim 2:** IPHR unfaithfulness rates range from ~0% up to ~13% of question pairs depending on the model, with gpt-4o-mini at the top. Reference numbers: the per-model dict hard-coded in the authors' figure script (`notebooks/plots_for_writeup.py :: save_iphr_plot :: unfaithful_count_by_model`, with `n_pairs = 4892`) — this is the paper's figure data.
9
+
10
+ **Method ($0, released artifacts only):**
11
+ 1. Rebuild the aggregate dataframe from the released judge evals: `scripts/iphr/make_df.py -i instr-wm -p non-ambiguous-hard-2` (~11 min, CPU) and compare per-system row counts against the released `d/df-wm-non-ambiguous-hard-2.pkl.gz`.
12
+ 2. Count unfaithful question-pairs per system from the released `d/faithfulness/<model>/` datasets, using the paper's selection rule: only property files matching the dataframe's dataset suffix (`*_non-ambiguous-hard-2.yaml`), counting entries of `questions_by_qid` (each entry is one question pair; integrity-checked for duplicate qids and pair double-counting via `metadata.reversed_q_id`).
13
+ 3. Total pairs per system = released df rows / 2 = 9,668 / 2 = **4,834** (the df has one CoT row per question; a pair is a question plus its reversal). Rates are also reported against the paper's hard-coded denominator `n_pairs = 4892` for direct comparison with the figure.

+ **Cross-check vs the paper's figure data: 9 of 16 systems match exactly**, including all four largest counts (gpt-4o-mini 660, claude-3.5-haiku 363, gemini-pro-1.5 320, qwq-32b 220). All 7 mismatches are small-count systems where the released archive yields **fewer** unfaithful pairs than the paper figure (differences of 1–27 pairs, ≤ 0.56 percentage points; largest: claude-3.7-sonnet 63 vs 90, i.e. 1.30% vs 1.84%). These low counts are threshold-sensitive — sweeping the pipeline's selection threshold moves them widely, and the released data sits uniformly on the more-conservative side — and the precise original cutoff is not recoverable from the shipped data's threshold settings (the shipped clone also carries only a single commit of history, so the original data pass cannot be inspected from its git log); the headline range endpoints reproduce exactly and are unaffected. See the Data Provenance page for the sensitivity sweep and the characterization of these deltas. The three gemma systems are present in the released data but explicitly filtered out of the paper's figure (small non-frontier models; `plots_for_writeup.py` drops them from the df before plotting) — their much higher rates (24.6–45.4%) do not bear on the frontier-model claim.
287
+
288
+ † gemma-2-2b released files hold 2,192 pairs, of which 1,794 regenerate byte-identically from the released dataframe; 398 pairs sit in 7 stale prop files not produced by the current pipeline (see Data Provenance). Either count leaves it far outside the paper's figure set.

296

297

The 18/19 exact row-count agreement between the released dataframe and our rebuild (the one non-matching system is fully explained on the Data Provenance page), plus 9/16 exact and 7/16 slightly-lower unfaithful-pair counts (threshold-sensitive, with the released data uniformly on the more-conservative side), mean the released archive reproduces the paper's figure to within small, one-directional deltas on low-count systems and exactly at the top of the range where the headline lives.

8
+ **Paper:** https://arxiv.org/abs/2503.08679 (OpenReview NUyt4uxzx0) — frontier models produce unfaithful chain-of-thought on natural, unmanipulated prompts, most prominently Implicit Post-Hoc Rationalization (answering YES to both `Is X > Y?` and its reversal, rationalizing each), at rates from ~0% up to ~13% of question pairs depending on the model.
9
+
10
+ **What we did:** verified both claims from the authors' released code and data (github.com/jettjaniak/chainscope @ bb128ac0; all 18 GB of responses, judge evals, and faithfulness datasets ship in-repo), running everything locally on an Apple Silicon Mac (Python 3.12; vllm/TransformerLens stubbed — no macOS wheels; no GPU, no API calls, **$0 total spend**). We re-ran the authors' full derivation pipeline (`make_df.py`, `make_faithfulness_ds.py`) on the released inputs and compared outputs byte-for-byte and count-for-count against the released artifacts.
11
+
12
+ **Claim 1 (IPHR occurs) — SUPPORTED at the data level.** The pipeline is deterministic: regenerating the faithfulness datasets for all 19 model systems from the released inputs rewrites the released YAMLs **byte-identically** (clean git tree) — with full file coverage for 18/19 systems; the one exception, gemma-2-2b (a non-figure baseline), regenerates 22/29 files byte-identically with 7 stale files from an earlier data state left untouched. The released data contains the phenomenon at scale (gpt-4o-mini alone: 660 unfaithful pairs, 4,752 unfaithful responses, with per-pair judge explanations of the YES/YES / NO/NO contradictions).
13
+
14
+ **Claim 2 (rates ~0% to ~13%, gpt-4o-mini max) — SUPPORTED at the data level.** Full 19-system recount from released data: min 0.04% (claude-3.7-sonnet_1k), max **13.65%** = 660/4,834 pairs for gpt-4o-mini (13.49% with the paper's n=4,892 denominator). 9/16 systems match the paper's figure counts exactly (including all four largest); 7 low-count systems come out slightly lower in the released archive (≤ 27 pairs, ≤ 0.56 pp) — see Data Provenance. Range and ranking of the published figure confirmed.
15
+
16
+ **Data provenance — RESOLVED.** The released eval archive holds 3× the gpt-4o-mini evals used in the published dataframe because it also ships the temperature-ablation runs (T0.3 and T1.0, gpt-4o-mini only); the released dataframe is cell-for-cell identical to a full-archive rebuild restricted to the paper's stated sampling run (T0.7/P0.9/M2000). The 7 low-count figure deltas are explained too: threshold sweeps of the authors' selection pipeline show the small-system counts are threshold-sensitive and directionally conservative (no tested setting reproduces the figure's dict), and the released dataframe itself pins down the mechanism — the figure's hard-coded counts equal the **pre-oversampling** pair counts (= half the `total_count == 100` rows per system, exact for all 8 oversampled systems), while the released faithfulness YAMLs reflect the post-oversampling reselection at the stricter 100-sample criterion.
17
+
18
+ **Scope:** data-level verification of released artifacts; fresh-generation runs not performed. Environment: $0, Apple Silicon, no paid APIs.

7
+ -->
8
+ **RESOLVED — the gpt-4o-mini archive surplus is the paper's temperature-ablation data.**
9
+
10
+ Rebuilding the aggregate dataframe from the released `cot_eval/` archive with the authors' `make_df.py` (`-i instr-wm -p non-ambiguous-hard-2`) yields 203,028 rows vs 183,692 released (+19,336). All 18 other systems match the released dataframe exactly at 9,668 rows each; the entire delta is `openai/gpt-4o-mini`: 29,004 rebuilt vs 9,668 released — exactly 3×.
11
+
12
+ **Cause, from the archive's directory structure:** `d/cot_eval/instr-wm/` contains three sampling-parameter directories — `T0.3_P0.9_M2000`, `T0.7_P0.9_M2000`, `T1.0_P0.9_M2000`. Every model has eval files only under T0.7 (116 dataset files each for the non-ambiguous-hard-2 datasets); **gpt-4o-mini is the only model that also has files under T0.3 and T1.0** (116 dataset files in each, same dataset coverage — mirrored in `cot_responses/`). These are the temperature-ablation runs (the clone's HEAD commit is literally "Clarify ablation study source label"). `make_df.py` rglobs across ALL sampling directories, so a naive rebuild ingests all three runs for gpt-4o-mini: 3 × 9,668 = 29,004.
13
+
14
+ **The paper's selection rule, verified exactly:** the paper generates CoTs "using temperature 0.7 and top-p 0.9" (Section 2.1), i.e. keep only the `T0.7_P0.9_M2000` run. The released dataframe contains only temperature=0.7 rows, and it is **cell-for-cell identical (0 mismatched cells across 183,692 rows × 26 columns)** to our full-archive rebuild restricted to `temperature == 0.7` (run cell below). No duplicate (temperature, dataset, qid) rows exist within any run. The released df is therefore a proper, rule-based subset of the archive: **rule = the paper's stated sampling configuration T0.7/P0.9/M2000**; the surplus (2 × 9,668 = 19,336 rows) is the T0.3 + T1.0 ablation data, which the published aggregate correctly excludes. All published rates are computed on the 9,668-row (4,834-pair) T0.7 subset.

118
+ **Secondary provenance finding — the figure's hard-coded counts: 9/16 reproduce exactly; 7 small-count systems differ slightly.**
119
+
120
+ The authors' figure script does not compute per-model unfaithful counts at plot time: the YAML-counting code in `notebooks/plots_for_writeup.py :: save_iphr_plot` is commented out and replaced by a hard-coded `unfaithful_count_by_model` dict (a reproducibility smell, though a benign one). Counting the released faithfulness datasets with the paper's own selection rule (Claim 2 page) matches that dict exactly for 9 of 16 systems — including every high-count system (660, 363, 320, 220, 159, 106, 102, 60, 2).
121
+
122
+ For 7 low-count systems the released archive yields FEWER pairs than the dict (claude-3.6-sonnet 12 vs 22, claude-3.7-sonnet 63 vs 90, claude-3.7-sonnet_64k 9 vs 12, deepseek-r1 13 vs 18, gemini-2.5-pro-preview 6 vs 7, chatgpt-4o-latest 15 vs 24, gpt-4o-2024-08-06 13 vs 18). These deltas do not reproduce by re-running the pipeline: the released faithfulness YAMLs regenerate byte-identically from the released dataframe + evals (Claim 1 page), so today's archive genuinely yields the lower numbers and the dict values come from an earlier data pass. (Our clone is shallow — `git clone --depth 1`, a single local commit — so the upstream commit history is not inspectable offline.) The cells below bound how threshold-sensitive these small counts are: the counts swing widely across nearby threshold settings, the released data sits uniformly on the more-conservative side, and the precise original cutoff is not recoverable from the shipped data's threshold settings alone (no tested or grid-swept setting reproduces the dict, and the shipped clone's single-commit history rules out inspecting the original data pass from its git log). A separate released-dataframe analysis further below identifies the pre-/post-oversampling snapshot difference as the mechanism behind the deltas. Impact is small and one-directional: ≤ 27 pairs / ≤ 0.56 percentage points, all on systems far below the headline; the range endpoints (~0% and ~13%, both reproduced exactly) are unaffected. Note the repo's bundled `paper.pdf` is an earlier arXiv version (7,400-pair unfiltered dataset, "3% to 19%"); the hard-coded dict corresponds to the published figure on the filtered non-ambiguous-hard-2 dataset, which is the released-data configuration verified here.

+ **Reading.** No tested setting reproduces any dict value exactly, and the response to loosening is heterogeneous: claude-3.6-sonnet brackets its dict value (12 < 22 < 25), claude-3.7-sonnet overshoots it in a single step (63 → 119, past 90), deepseek-r1 brackets it narrowly (13 < 18 < 20), and chatgpt-4o-latest never reaches its dict value even at `-a 0.3` (21 < 24). The correct characterization is therefore limited: **small-system counts are threshold-sensitive and directionally conservative** (the released archive at the pipeline's defaults always lands *below* the figure's dict), **but the exact original cutoff / data pass is not pinned down by this evidence alone.** Indeed it cannot be pinned down this way: `-a` only loosens the 10-response cutoff, while — as the next cells show — the dict pairs are all *oversampled* (100-response) pairs, so no `-a` sweep can reconstruct the dict. The released-dataframe analysis below identifies the actual mechanism.

271
+
272
+ The paper's hardcoded per-system unfaithful-pair dict in
273
+ notebooks/plots_for_writeup.py (~line 813) equals the PRE-OVERSAMPLING count:
274
+ the number of pairs flagged unfaithful at the 10-responses/question stage.
275
+ Flagged pairs of 8 frontier systems were then oversampled to 100 responses/
276
+ question; the released df + faithfulness YAMLs reflect the POST-oversampling
277
+ reselection (make_faithfulness_ds defaults: oversampled threshold 0.4 on
278
+ 100-sample p_correct), which culls pairs whose accuracy gap regressed.
279
+
280
+ Proof (this script, read-only, released df only):
281
+ For every mismatched system, (#df rows with total_count==100)/2
282
+ == dict value EXACTLY (8/8 incl. claude-3.7-sonnet_1k), the oversampled
283
+ questions pair up perfectly (0 unpaired), and today's selected pairs are a
284
+ strict subset of the oversampled pairs.
285
+ Corroboration IN THE REPO: save_oversampling_plot() hardcodes retention
286
+ percentages whose implied originals = dict values and whose new_totals
287
+ (12, 63, 2, 9, 13, 15, 13, 7) = released YAML counts (gemini-2.5-pro is 6
288
+ in released YAMLs vs 7 in that plot: its 7th pair sits at 100-sample
289
+ |acc_diff| = 0.335 < 0.4; chatgpt-4o-latest's plot 'original' is 22 vs
290
+ dict/oversampled 24: 2 pairs were oversampled after the plot was made).
291
+ Hypothesis sweeps that FAILED (see verify_threshold_sweep.py):
292

401
+ **RESOLVED — the dict values are the pre-oversampling pair counts.** The pipeline oversampled the flagged pairs of 8 frontier systems from 10 to 100 responses per question and re-selected them under the stricter 100-sample criterion (`-oa 0.4` applied to 100-sample `p_correct`), culling pairs whose accuracy gap regressed below 0.4. From the released dataframe alone (`verify_oversampling_rule.py`, read-only, above): for every one of the 8 oversampled systems — the 7 mismatched ones plus claude-3.7-sonnet_1k (which matches the dict) — (number of df rows with `total_count == 100`) / 2 **equals the figure dict exactly** (22, 90, 2, 12, 18, 7, 24, 18), the oversampled questions pair up perfectly (0 unpaired), today's selected pairs are a subset (⊆) of the oversampled pairs, and an in-memory replica of the selection reproduces the released YAML counts (12, 63, 2, 9, 13, 6, 15, 13).
402
+
403
+ In-repo corroboration: `save_oversampling_plot()` in the same notebook hard-codes retention percentages whose implied originals equal the dict values and whose new totals equal the released YAML counts — with two explainable wrinkles: gemini-2.5-pro-preview shows 7 in that plot vs 6 released (its 7th pair sits at 100-sample |acc_diff| = 0.335 < 0.4), and chatgpt-4o-latest's plot "original" is 22 vs dict 24 (2 pairs were oversampled after that plot's numbers were frozen).
404
+
405
+ **Net:** the figure's hard-coded dict is the **pre-oversampling** snapshot of the flagged-pair counts; the released archive is the **post-oversampling** state. The 7 deltas are fully mechanistic, small, and one-directional — re-selection under a stricter, better-sampled criterion can only remove pairs — and the published range endpoints (~0% and ~13%, both reproduced exactly) are unaffected.
