# KAIROS-Thinking-Abduction-5k

**5,001 synthetic examples that teach abductive reasoning: how to pivot from a failed hypothesis to a cross‑domain breakthrough.**

Most instruction datasets reward deductive step‑by‑step answers. KAIROS targets the other half of scientific thinking — the *Eureka* moment: recognising that the current frame is wrong, borrowing an analogy from an unrelated field, and proposing a novel but testable hypothesis.

This is a mirror of the public Kaggle dataset [`dimsimd/kairos-thinking-5k`](https://www.kaggle.com/datasets/dimsimd/kairos-thinking-5k) (CC0‑1.0), with two malformed JSON lines repaired and a dataset card added.

## Dataset structure

One JSON object per line, 13 fields, identical across all records.

| Field | Type | Description |
|---|---|---|
| `discovery_topic` | `string` | The scientific breakthrough or invention being reasoned about |
| `category` | `string` | Domain label (e.g. `Physics`, `Computer Science`, `Space Technology`) |
| `context` | `string` | Technical background, historical setting and constraints |
| `standard_logic_failure` | `string` | Why conventional deductive reasoning reached a dead end — the mental block |
| `failed_hypothesis` | `string` | The specific approach that was tried and failed |
| `why_it_failed` | `string` | Root‑cause analysis of the failure |
| `correction` | `string` | The conceptual shift required to escape the dead end |
| `the_pivot` | `string` | **The crucial insight** — usually a cross‑domain analogy |
| `reasoning_trace` | `string` | Chain‑of‑thought style monologue: confusion → clue → re‑framing → clarity |
| `inventive_hypothesis` | `string` | The resulting breakthrough solution |
| `novelty_score` | `float` | Self‑reported novelty, 0.6 – 0.95 (mean 0.81) |
| `cross_domain_distance` | `list[string]` | 1–3 fields the analogy was drawn from (mean 3.0) |
| `implementation_feasibility` | `float` | Self‑reported feasibility, 0.2 – 0.9 (mean 0.71) |

### Example

First record, with long strings truncated (marked `…`):

```json
{
  "discovery_topic": "Transistor",
  "category": "Physics",
  "context": "In the early 20th century, the primary challenge in electronics was to find a reliable alternative to vacuum tubes, which were bulky, consumed high power (typically 5-10 watts per tube), and had limited lifespans often less than 1000 hours. …",
  "standard_logic_failure": "The fundamental flaw in deductive reasoning was the assumption that vacuum tubes could be indefinitely improved to meet the demands of modern electronics. …",
  "failed_hypothesis": "Attempted to improve vacuum tube performance using barium-strontium oxide-coated cathodes and improved grid structures …",
  "why_it_failed": "The improved vacuum tubes still suffered from high power consumption …",
  "correction": "The fundamental shift involved moving from vacuum-based electronics to solid-state devices …",
  "the_pivot": "The cross-domain analogy came from observing the behavior of semiconductors in radio receivers and the study of quantum mechanics. …",
  "reasoning_trace": "Initial observations of semiconductor materials showed that they could rectify electrical signals, but their behavior was inconsistent and poorly understood. …",
  "inventive_hypothesis": "The breakthrough idea was to use a semiconductor material with precisely controlled impurities (doping) to create a three-layer structure (p-n-p or n-p-n) that could amplify electrical signals. …",
  "novelty_score": 0.9,
  "cross_domain_distance": ["solid-state physics", "quantum mechanics", "materials science"],
  "implementation_feasibility": 0.6
}
```

## Usage

```python
from datasets import load_dataset

ds = load_dataset("DimSimd/kairos-thinking-5k", split="train")
print(ds[0]["the_pivot"])
```

Ready‑made chat / SFT formatting (the teacher prompt suggested by the dataset author):

```python
SYSTEM_PROMPT = (
    "You are Project KAIROS. When faced with a problem, use Abductive "
    "Reasoning and Cross-Domain Analogies inside your thinking process."
)

def to_chat(row):
    assistant = (
        f"## Context\n{row['context']}\n\n"
        f"## Why standard logic fails\n{row['standard_logic_failure']}\n\n"
        f"## Failed hypothesis\n{row['failed_hypothesis']}\n"
        f"### Why it failed\n{row['why_it_failed']}\n\n"
        f"## Correction\n{row['correction']}\n\n"
        f"## The pivot\n{row['the_pivot']}\n\n"
        f"## Breakthrough hypothesis\n{row['inventive_hypothesis']}"
    )
    return [
        {"role": "system", "content": SYSTEM_PROMPT},
        {"role": "user", "content": f"Challenge: {row['discovery_topic']}.\n{row['context']}"},
        {"role": "assistant", "content": assistant},
    ]
```

The raw `reasoning_trace` field can also be wrapped in `<think>...</think>` blocks if you are training an explicit reasoning model.

## Intended use

* SFT / LoRA fine‑tuning for scientific and engineering reasoning
* Training "failure → re‑framing → hypothesis" behaviour rather than answer recall
* Benchmarks and prompts exploring cross‑domain analogy generation
* Research on synthetic reasoning data and self‑correction

### Limitations

* **Fully synthetic**, generated by **Mistral‑Medium** from expert‑system prompts. Historical narratives are plausible but not fact‑checked; treat `context` and `failed_hypothesis` as narrative scaffolding, not as a historical source.
* `novelty_score` and `implementation_feasibility` are model self‑assessments on a narrow range, not calibrated measures.
* Category labels are inconsistent (36 raw variants, including one‑off slash‑combined labels).
* Duplicate themes exist across `discovery_topic` values; 4,434 unique topics over 5,001 records.
* English only.

## Provenance and repairs

Source: [`https://www.kaggle.com/datasets/dimsimd/kairos-thinking-5k`](https://www.kaggle.com/datasets/dimsimd/kairos-thinking-5k), original file `eureka_kairos_v1_5k.jsonl` (31,039,929 bytes, 5,000 physical lines).

The upstream file contains two corrupt lines. Both were repaired **without dropping any content**, giving 5,001 valid records:

1. **Line 4401** — duplicated object prefix: `{"disc{"discovery_topic": "Biohybrid Robots", ...`. Removed the extra `{"disc`.
2. **Line 5000** — two records concatenated, the second missing its opening `{"discov`: `...0.7}ery_topic": "Cold Storage via DNA Data Archiving", ...`. Split into two objects and restored the truncated key, yielding one extra valid record.

The untouched upstream file is kept at `original/eureka_kairos_v1_5k.jsonl` for verification. No other bytes were changed; field values, ordering and text are as published.
