Information-Gathering vs. Confession-Based Interviewing: The Future of Investigative Interviewing

Investigative interviewing stands at a crossroads, split between two fundamentally different approaches: information-gathering and "the way we've always done it," confession-based techniques. The first focuses on collecting accurate, detailed, reliable case information. The second chases a confession—usually starting from an assumption of guilt and often leaning on junk science to bend the entire process toward that single goal.

Those are not two flavors of the same skill. They are two different jobs. Two antithetical paradigms. This article compares them and explains why the future of effective interviewing and interrogation—in law enforcement, corporate investigations, HR, compliance, and loss prevention—belongs to the information-gathering approach.

Information-Gathering Interviewing: Science-Based and Evidence-Driven

Information-gathering interviews, including science-based interviewing (SBI), rely on research-backed strategies: rapport-building, open-ended questioning, active listening, and structured interview planning. The goal is an environment that encourages voluntary, cooperative disclosure and thorough accounts of events—without contaminating the statement.

Science-based investigative interviewing beats outdated legacy techniques across every interview metric, including admissions and confessions, according to field-validation research

Techniques like the Strategic Use of Evidence (SUE) sharpen credibility assessment and pull more case-relevant information by presenting evidence gradually and non-confrontationally, rather than slapping it on the table to win an argument.

Notably, SBI rejects outdated, pseudoscientific tactics such as nonverbal "lie detection," which reinforce confirmation bias and manufacture investigative risk by generating false case information.

This isn't just theory. Two recent field validation studies took these methods out of the lab and into real interview rooms—real investigators, real suspects, and actual interviews recorded before and after training.

In the first, 90 federal, state, and local investigators were recorded before and after a week-long science-based interviewing course (Russano et al., 2024). Afterward, they asked more productive, open-ended questions; built more rapport; and used far more of the cognitive interview—a large effect—while cutting unproductive questioning. The second study ran the same test on a practitioner-designed course, across 43 investigators at three local agencies, and found the same shift toward rapport, productive questioning, and cognitive-interview skills (Russano et al., 2026). Two different studies across four states, including two major cities police departments and federal investigators, had the same result.

And here's the finding that matters most—the whole argument in one line. In both studies, science-based tactics were associated with more cooperation, more information disclosure, and, through that, more admissions and confessions. Accusatory, confession-based tactics were associated with the exact opposite: more suspect resistance (what researchers call counter-interrogation behavior), less cooperation, and less information. In each study, the science-based pathway explained more than half of all the variation in how much information suspects actually disclosed. The 2026 team stated it plainly: the data strongly support science-based techniques and should push investigators to reduce their reliance on traditional accusatory ones. More of what you actually need, and no loss of the thing everyone is afraid to give up.

So here's the question, dear reader. If you're a corporate investigations leader, a chief, a sheriff, or the person who decides what your team gets trained in—and the evidence is now this clear—what choice are you actually making? Upgraded interviewing that pulls more information, more cooperation, and more reliable admissions? Or the comfort of "the way we've always done it." It's now not a matter of interview style; it's a decision to get more or less information in your investigations.

The Confession-Based Model: Presumption, Pressure, and Pseudoscience

Confession-based, legacy, and accusatory methods run on an assumption of guilt and try to extract admissions followed by confessions through pressure and psychological tactics. In practice, that toolkit includes:

• Minimizing the seriousness of the offense

• Offering moral justifications for the crime

• False evidence ploys—telling a subject you have proof you don't

• Repeated, confrontational questioning

• Shutting down denials before they're finished

• Deciding "probable guilt" through unproven lie-detection cues

Each of these is designed to move a person toward "yes." None of them is designed to find out what actually happened. That is by definition not the truth.

The Danger of False Confessions

Confession-based methods carry a real, documented cost. Research shows these tactics can and do produce false confessions, especially among juveniles and other vulnerable individuals. According to the Innocence Project, roughly 1 in 4 DNA-exoneration cases involved a false confession or admission.

Kassin and colleagues (2010) sort false confessions into three types:

• Voluntary — offered without external pressure.

• Coerced-compliant — given to escape a stressful interrogation, with no belief in one's own guilt.

• Coerced-internalized — where an innocent person actually begins to believe they did it.

False confessions don't just harm the person in the chair. They derail investigations, leave the actual perpetrator free to reoffend (and they do), and corrode public trust in the entire criminal justice system. In a private-sector setting, the same failure mode plays out as a wrongful termination, false imprisonment, a botched fraud case, or a lawsuit built on a "confession" that never should have counted as evidence.

The Case Against Accusatory Techniques

Accusatory tactics lean on deception, suggestive questioning, and "lie detection" cues with no scientific grounding. They can taint statements, lock in a single narrow theory of the case, burn investigative resources, and — at the extreme — help produce wrongful outcomes. That is why this author dubs them the "terrible two."

Warning label for accusatory techniques and pseudoscientific lie detection practices (the "terrible two") that create bias, false case information, and, at their worst, false confessions/wrongful convictions.

Making a confession the primary goal is short-sighted. It shrinks the scope of the investigation and routinely fails to surface the additional, corroborating evidence a case needs to stand up. These techniques are relics — the equivalent of running your operation on obsolete equipment that underperforms and introduces avoidable risk (And you won't believe what's still being taught in the 2020s—read this.)

Newer, evidence-based methods do two things at once: they produce more accurate, more complete case information—a lot of it—and they remain effective at obtaining reliable confessions, without inflating the risk of false information or false confessions. There is no trade-off to defend here.

And beyond legal or financial jeopardy, accusatory techniques damage trust—in law enforcement and in the credibility of a corporate investigation's functions with internal stakeholders. When community relationships and organizational credibility matter more than ever, clinging to outdated tactics sends exactly the wrong message to the public, to employees, and to the next generation of investigators.

This Isn't an Indictment of the Past

Let me be clear about something, because it has to be said.

None of this is an indictment of the investigators who came up with accusatory methods. I used them. I was trained in them, and I used them on real cases—not out of carelessness, but because those were the tools we were handed, and they were taught to all of us as best practice. At the time, it was all we had access to. You work with what you're given, and we did.

But "best practice" isn't a monument. It's a snapshot of what we knew when the picture was taken—and what we know has changed. The research caught up. The field validation is in. What was considered sound a couple decades ago is no longer the best we can do, because we now have methods that are measurably more effective and much safer. Continuing to use the old ones after you know that isn't loyalty to the craft or our profession. It's the opposite.

Being a good investigator has never meant defending the way things were done. It has meant going where the evidence leads. This is simply the same discipline we demand in every case, turned on our own profession: follow the evidence, update the conclusion, and act on it.

We are not guardians of the past. We are investigators. The job is to get it right — and getting it right means upgrading the moment we know better.

Science-Based Interviewing: The Path Forward

Training in information-gathering methods like science-based interviewing isn't a nicety for any professional investigator—whether in law enforcement, corporate security, HR, workplace and internal investigations, loss prevention, or compliance. These approaches are engineered to collect more information and more accurate information, making interviews not merely longer but more productive, reliable, and verifiable.

SBI shifts the focus from extracting a confession or confirming a theory to uncovering the facts. It emphasizes preparation, rapport, open-ended questioning, and evidence-based strategies like Cognitive Interviewing, ORBIT, and the Strategic Use of Evidence (SUE). Research consistently shows these methods increase both the quantity of information (information yield) and its quality—accuracy, verifiability, and case relevance. The terrible two tell you to trust them because they said so.

Just as important, SBI removes reliance on discredited tactics: minimization, alternative questions, false evidence ploys, and nonverbal "lie detection." Those legacy moves aren't just less effective—they're known risk factors for false confessions, and the reason lie-detection training so often teaches the wrong lesson.

Train investigators in validated, research-backed methods, and you remove the guesswork, cut investigative error, and strengthen both trust and case outcomes at the same time. SBI isn't just the safer option. It's the smarter, more effective one. (New to the term? Start with what science-based interviewing is and why it matters).

Think of it the way you'd think about any other tool your team depends on: this is an upgrade. You don't keep running critical work on obsolete gear once a better, validated version exists—you upgrade because the old version costs you accuracy, time, and credibility every day you keep it. Your interviewing is no different. It's time to upgrade.

Conclusion: Ethical Interviews, Better Outcomes

The distinction between confession-based and information-gathering approaches isn't academic. It determines the reliability of your investigations, the safety of innocent people, and the integrity of the outcome—whether that outcome is a conviction or an internal finding a general counsel has to defend. After all, who wants to make confession case law?

Confession-driven interviews risk false confessions, contaminated statements, and flawed conclusions. Information-gathering methods like SBI and the cognitive interview represent a deliberate shift toward cooperation, accuracy, and ethical professionalism.

The future of investigative interviewing was never about collecting more confessions. It's about getting the truth—reliably, accurately, and with the science to back it up.

So upgrade your interviewing. Better information, better cooperation, and yes, more reliable admissions and confessions — leading to better investigations, better decisions, and better justice.
