Internal Validity Deductive Reasoning (IVDR): A Forensic Framework for Evaluating Institutional Misconduct

“When the system lies, the archive speaks—this is the reckoning they never saw coming.”

How Truth Is Tested Through Internal Validity Deductive Reasoning (IVDR)

IVDR is not a theory, it is a protocol. Developed by Rev. Dr. Jan Lightfoot, it empowers investigators to test the truth of institutional claims using the actor's own documents. Through contradiction mapping, logic sequencing, and legal compliance testing, IVDR confirms when harm isn't speculative, it's documented. The white paper codifies the method and applies it to constitutional violations where identity, dignity, and personhood were procedurally erased. When internal contradiction, illegality, and deductive collapse combined, the institution becomes its own witness.
