Mostafa190/TwinnyAI-Personas-Dataset

Overview

The TWINNY.AI Personas Dataset is a synthetic collection of 400 richly structured professional personas, engineered to power behavioral AI twins, persona-driven language model fine-tuning, and professional simulation systems.

Each persona is built from 14 attributes spanning demographics, professional context, behavioral psychology, and communication style sampled with realistic non-uniform distributions that mirror actual workforce demographics rather than uniform random sampling.

This dataset is the core training resource for the TWINNY.AI project: a system designed to create AI behavioral twins that authentically reflect human professional archetypes across industries, seniority levels, and cultural contexts.

📊 Behavioral Score Summary (scale 1–5)

Score Field	Mean	Std	Min	Max	Interpretation
risk_tolerance_score	3.24	~1.1	1	5	Slight risk appetite
approval_threshold_score	3.18	~1.1	1	5	Moderate validation need
ai_trust_score	3.14	~1.1	1	5	Mild AI openness

confidence_score	2.91	~1.1	1	5	Slightly below-neutral (realistic)

Scores follow Gaussian distributions centered at 3.0 with σ ≈ 1.0–1.2, with role-level biases applied via the pipeline's ROLE_RISK_BIAS and ROLE_APPROVAL_BIAS lookup tables.

🤝 Delegation Preference

Preference	Count	%
Comfortable delegating (TRUE)	~218	54.5%
Prefers direct control (FALSE)	~182	45.5%

Generated via random.random() > 0.45 - approximately 55% of personas prefer delegation.

Behavioral Trait Correlations

The dataset encodes realistic role-level behavioral biases, not random sampling:

Role	Risk Tolerance Bias	Approval Need Bias	Confidence Bias
Junior	−1 to 0 (cautious)	+1 to +2 (high)	−1 to 0
Mid-level	0 (neutral)	0 to +1	−1 to 0
Senior	0 to +1 (bold)	−1 to 0 (low)	0 to +1
Manager	−1 to +1 (spread)	−1 to +1	0 to +1
Director	0 to +1	−2 to 0	0 to +1
Executive	+1 to +2 (high)	−2 to −1 (very low)	0 to +1

This means an Executive persona statistically shows high risk tolerance + low approval seeking, matching real-world behavioral research, while a Junior persona trends toward caution and external validation.

Generation Pipeline

Script	Role
01_generate_personas.py	Samples traits with weighted distributions, applies role-level biases, generates 400 personas with seed=42
03_validate_dataset.py	Schema validation, duplicate removal, score range checks
04_export_jsonl.py	Exports to JSONL training format
groq_generator.py	Optional: enriches personas with LLM-generated narrative descriptions via Groq API

Fully reproducible: Running generate_personas(n=400, seed=42) produces the exact same 400 personas every time.

---

Intended Use

• LLM fine-tuning : Train models to generate or simulate professional personas
• Behavioral AI twins : Power digital twin systems with realistic archetypes
• AI agent seeding : Consistent behavioral profiles for role-play agents
• Prompt engineering : System prompt templates for persona-conditioned generation
• UX research & simulation : Diverse synthetic user profiles for product testing
• Academic research : Study trait distributions in synthetic professional populations

Out-of-Scope Use

• Impersonating or deceiving real individuals
• Building surveillance or profiling systems targeting real people
• Generating discriminatory content based on demographic attributes

---

Ethics & Limitations

• Bias transparency : Cultural distributions reflect configurable pipeline priors (e.g., 30% North American). These are adjustable weights, not value judgments
• Score design : Gaussian-sampled scores with σ ≈ 1.0–1.2; extremes (1 or 5) exist but are intentionally less frequent
• No PII : Zero personally identifiable information in any field
