Science-Based Interviewing for High-Stakes Decisions

In high-stakes investigations and organizational decisions, the quality of information matters more than confidence, experience, or intuition.

​

​Yet many interviews that feel productive ultimately produce fragile information—information shaped by assumptions, bias, or untested interpretations rather than evidence.  The failure often isn’t obvious in the interview room. It shows up later, when decisions are questioned, cases unravel, or outcomes don’t withstand scrutiny.

​

Science-Based Interviewing (SBI) addresses this problem by treating interviews as a form of evidence handling and decision support, not persuasion.

The Hidden Problem with “Good” Interviews

Most interview failures don’t look like failures at the time.

​

They look like:

  • Clear narratives formed too early

  • Confidence in conclusions

  • Smooth conversations that feel cooperative

  • Notes and summaries that reinforce an existing theory

​

The issue isn’t effort or intent. It’s that information is often gathered and interpreted simultaneously, without sufficient safeguards. When that happens, statements become contaminated, selectively emphasized, or prematurely treated as corroboration.

 

Once this occurs, downstream decisions—investigative, legal, or organizational—are built on unstable ground.

Why Traditional Interviewing Methods Fall Short

Many legacy and popular interviewing approaches emphasize:

  • Extracting admissions

  • Identifying deception through behavioral cues

  • Applying tactics or themes designed to influence responses

 

These approaches share a common flaw: they prioritize outcomes over information integrity.

​

Research consistently shows that:

  • People are poor lie detectors

  • Confidence is not a reliable indicator of accuracy

  • Memory is reconstructive and highly sensitive to suggestion

  • Experience alone does not protect against cognitive bias

 

When interviews are designed to confirm beliefs rather than test them, even well-intentioned professionals can unknowingly shape what they hear.

What Science-Based Interviewing Actually Is

Science-Based Interviewing is not a single technique. It is a framework grounded in decades of peer-reviewed research from psychology, memory science, communication, and decision-making.

At its core, SBI emphasizes:

🧠 Memory-Informed Practices

  • Free narratives before specific questioning (unknown unknowns!)

  • Avoiding premature interruptions

  • Allowing self-generated retrieval cues

🗣️ Communication with Discipline

  • Open-ended, neutral, non-leading questions

  • Active listening without steering

  • Clarifying without contaminating

📂 Strategic Use of Evidence (SUE)

  • Planned, phased disclosure of known evidence

  • Testing account veracity rather than confronting beliefs

  • Separating information gathering from evaluation

🧭 Bias Awareness with Structure

  • Guardrails against confirmation bias

  • Distinguishing what was said from what is inferred

  • Structural techniques to improve interviewing

 

SBI does not eliminate judgment. It delays it, ensuring decisions are informed by the fullest and most reliable information possible.

Interviewing as Decision Support, Not Tactics

Interviewing is often treated as a “soft skill.” In reality, it is one of the most consequential decision-support functions in any organization.

 

Statements influence:

  • Investigative direction

  • Resource allocation

  • Disciplinary action

  • Legal exposure

  • Public trust

 

Science-Based Interviewing reframes the interview as a critical input into decision-making, where the standard is not persuasion but information integrity.

Real-World Implementation and Results

Science-Based Interviewing is not theoretical.

​

As a former Commander of the Crimes Against Persons Bureau with a large Midwestern agency, I implemented SBI alongside quality-control systems and modernized investigative practices informed by behavioral research. This approach produced measurable outcomes, including:

  • Increasing fatal shooting homicide clearance rates from 62% to 86%

  • Improving non-fatal shooting clearance rates from 38% to 61%

  • Leading the agency’s first two Investigative Genetic Genealogy (IGG) cases, solving a cold-case homicide and a stranger sexual assault

  • Modernizing interview rooms and documentation practices

  • Establishing structured case review and bias-reduction processes

  • Creating the Domestic Intervention and Violence Reduction Team (DIVRT) to improve accountability, coordination, and victim safety

 

These outcomes were not the result of better tactics—they came from better investigative and information discipline.

Who Science-Based Interviewing Is For

Science-Based Interviewing applies anywhere decisions rely on human statements, including:

  • Law Enforcement & Public Safety
    Investigations, critical incidents, and complex cases

  • Corporate Investigations & Compliance
    Internal investigations, ethics inquiries, and regulatory matters

  • Human Resources
    Workplace allegations, misconduct investigations, and high-risk interviews

  • Executive & Leadership Teams
    Decision-making under uncertainty and reputational risk

 

Wherever information quality matters, SBI provides a defensible framework.

The Standard Moving Forward

Science-Based Interviewing does not promise perfect outcomes. It promises something more valuable:

  • Fewer blind spots

  • Better information

  • Stronger decisions

  • Reduced risk

  • Greater credibility

 

In high-stakes investigative environments, that difference matters.
