01 — The Problem

The problem with legacy interviewing.

Confession-driven, accusatorial techniques were built on assumptions — not evidence. Modern research has exposed their cost: wrongful convictions, contaminated information, and decisions that cannot withstand scrutiny.

01

Assumptions create risk

Confirmation bias and shortcut thinking lead investigators to the wrong conclusions and expose organizations to liability.

02

Coercion contaminates information

Pressure-based tactics produce unreliable statements, suppressed evidence, and reversed convictions.

03

Poor questions reduce reliability

Closed-ended and suggestive questioning corrupts memory and yields shallow, ambiguous information.

04

Bias distorts decisions

Unexamined assumptions shape who is interviewed, what is asked, and what gets believed.

05

Organizations need defensible records

Investigations must withstand legal, regulatory, and public scrutiny — the process matters as much as the outcome.

02 — The Alternative

The science-based alternative.

SBI replaces outdated, coercion-based interviewing with research-validated methods designed to gather accurate, complete, and defensible information.

Rapport-Building

Foundation of every reliable interview.

Active Listening

Hear what's said and what's not.

Strategic Use of Evidence (SUE)

Disclose evidence with intention, not as a bluff.

Cognitive Interviewing

Recover accurate, detailed memory.

Red Teaming

Stress-test theories before they harden.

Bias Reduction

Systematic checks on assumption-driven thinking.

03 — Proven Results

Real-world outcomes from real agencies.

When agencies adopt science-based interviewing as a discipline — not a one-day class — the data shifts. Clearance rates rise. Cooperation deepens. Decisions hold up.
