biasclear 1.1.0

Structural bias detection engine built on Persistent Influence Theory (PIT). Detect framing, anchoring, false consensus, and 30+ rhetorical distortion patterns.

BiasClear

Structural bias detection and correction engine built on Persistent Influence Theory (PIT).

BiasClear identifies and corrects structural bias in text — not surface-level sentiment, but the deeper patterns that shape how information is framed, weighted, and presented. It uses a frozen ethics core (immutable code, not tunable weights) to evaluate text against epistemological principles.

Features

• Scan — Detect structural bias patterns (framing, anchoring, authority, omission, false equivalence)
• Correct — Generate debiased alternatives with inline diffs
• Score — Calculate truth alignment scores based on PIT principles
• Audit — SHA-256 blockchain audit chain for every evaluation
• Frozen Ethics Core — Immutable governance engine that cannot be prompt-injected

Quick Start

# Install
pip install -e .

# CLI usage
biasclear scan "The data clearly proves that this approach is the only viable option."
biasclear correct "Studies overwhelmingly show..."

# API server
pip install -e ".[api]"
uvicorn biasclear.api:app --port 8100

Client SDK

A Python client SDK for consuming the BiasClear API is included in biasclear-client/:

pip install -e ./biasclear-client

from biasclear_client import BiasClearClient

client = BiasClearClient(base_url="http://localhost:8100", api_key="your-key")
result = client.scan("The data clearly shows...")
print(result.flags)

See biasclear-client/README.md for full SDK documentation.
