<essential_principles>

**Culture Index measures behavioral traits, not intelligence or skills. There is no "good" or "bad" profile.**

<principle name="never-compare-absolutes"> **Never compare absolute trait values between people.**

The 0-10 scale is just a ruler. What matters is **distance from the red arrow** (population mean at 50th percentile). The arrow position varies between surveys based on EU.

**Why the arrow moves:** Higher EU scores cause the arrow to plot further right; lower EU causes it to plot further left. This does not affect validity—we always measure distance from wherever the arrow lands.

**Wrong**: "Dan has higher autonomy than Jim because his A is 8 vs 5" **Right**: "Dan is +3 centiles from his arrow; Jim is +1 from his arrow"

Always ask: Where is the arrow, and how far is the dot from it? </principle>

<principle name="survey-vs-job"> **Survey = who you ARE. Job = who you're TRYING TO BE.**

> **"You can't send a duck to Eagle school."** Traits are hardwired—you can only modify behaviors temporarily, at the cost of energy.

  • **Top graph (Survey Traits)**: Hardwired by age 12-16. Does not change. Writing with your dominant hand.
  • **Bottom graph (Job Behaviors)**: Adaptive behavior at work. Can change. Writing with your non-dominant hand.

Large differences between graphs indicate behavior modification, which drains energy and causes burnout if sustained 3-6+ months. </principle>

<principle name="distance-interpretation"> **Distance from arrow determines trait strength.**

| Distance | Label | Percentile | Interpretation | |----------|-------|------------|----------------| | On arrow | Normative | 50th | Flexible, situational | | ±1 centile | Tendency | ~67th | Easier to modify | | ±2 centiles | Pronounced | ~84th | Noticeable difference | | ±4+ centiles | Extreme | ~98th | Hardwired, compulsive, predictable |

**Key insight:** Every 2 centiles of distance = 1 standard deviation.

Extreme traits drive extreme results but are harder to modify and less relatable to average people. </principle>

<principle name="l-and-i-exception"> **L (Logic) and I (Ingenuity) use absolute values.**

Unlike A, B, C, D, you CAN compare L and I scores directly between people:

  • Logic 8 means "High Logic" regardless of arrow position
  • Ingenuity 2 means "Low Ingenuity" for anyone

Only these two traits break the "no absolute comparison" rule. </principle>

When to Use

  • Interpreting Culture Index survey results (individual or team)
  • Analyzing CI profiles from PDF or JSON data
  • Assessing team composition using Gas/Brake/Glue framework
  • Detecting burnout risk by comparing Survey vs Job graphs
  • Defining hiring profiles based on CI trait patterns
  • Coaching managers on how to work with specific CI profiles
  • Predicting CI traits from interview transcripts
  • Mediating team conflict using CI profile data

When NOT to Use

  • For non-CI behavioral assessments (DISC, Myers-Briggs, StrengthsFinder, Predictive Index, Enneagram)
  • For clinical psychological assessments or diagnoses
  • As the sole basis for hiring/firing decisions — CI is one data point among many

<input_formats>

**JSON (Use if available)**

If JSON data is already extracted, use it directly:

import json
with open("person_name.json") as f:
    profile = json.load(f)

JSON format:

{
  "name": "Person Name",
  "archetype": "Architect",
  "survey": {
    "eu": 21,
    "arrow": 2.3,
    "a": [5, 2.7],
    "b": [0, -2.3],
    "c": [1, -1.3],
    "d": [3, 0.7],
    "logic": [5, null],
    "ingenuity": [2, null]
  },
  "job": { "..." : "same structure as survey" },
  "analysis": {
    "energy_utilization": 148,
    "status": "stress"
  }
}

Note: Trait values are `[absolute, relative_to_arrow]` tuples. Use the relative value for interpretation.

Check same directory as PDF for matching `.json` file, or ask user if they have extracted JSON.

**PDF Input (MUST EXTRACT FIRST)**

⚠️ **NEVER use visual estimation for trait values.** Visual estimation has 20-30% error rate.

When given a PDF: 1. Check if JSON already exists (same directory as PDF, or ask user) 2. If not, run extraction with verification:

   uv run --no-project {baseDir}/scripts/extract_pdf.py --verify /path/to/file.pdf [output.json]

3. Visually confirm the verification summary matches the PDF 4. Use the extracted JSON for interpretation

**If uv is not installed:** Stop and instruct user to install it (`brew install uv` or `curl -LsSf https://astral.sh/uv/install.sh | sh`). Do NOT fall back to vision.

**PDF Vision (Reference Only)**

Vision may be used ONLY to verify extracted values look reasonable, NOT to extract trait scores.

</input_formats>

<intake>

**Step 0: Do you have JSON or PDF?**

1. **If JSON provided or found:** Use it directly (skip extraction)

  • Check same directory as PDF for `.json` file with matching name
  • Check if user provided JSON path

2. **If only PDF:** Run extraction script with `--verify` flag

   uv run --no-project {baseDir}/scripts/extract_pdf.py --verify /path/to/file.pdf [output.json]

3. **If extraction fails:** Report error, do NOT fall back to vision

**Step 1: What data do you have?**

  • **CI Survey JSON** → Proceed to Step 2
  • **CI Survey PDF** → Extract first (Step 0), then proceed to Step 2
  • **Interview transcript only** → Go to option 8 (predict traits from interview)
  • **No data yet** → "Please provide C
