Why Investigations Fail: The Hidden Architecture of Human Thinking

The hidden architecture of human thinking — and why the future of interviewing isn't just better technique. It's better thinkers.

Mark Anderson 8 min read

Before we begin, I want to tell you why I'm writing this series, and why it matters.

For years, interview training has focused almost entirely on technique: the right question, the right sequence, the right strategy, the right model. Technique matters, of course it does, but technique alone doesn't build an interviewer.

What builds an interviewer is something deeper: how they think, how they interpret, how they regulate themselves, and how they make sense of people.

That's the purpose of this series.

Over the coming articles, we'll explore the intersection of science-based interviewing and Red Teaming, a discipline designed to challenge assumptions, slow down thinking, and protect decision quality. We'll look at why investigations fail, how our minds mislead us, and how we can build a cognitive posture that is more accurate, more ethical, and more resilient.

This series is not about adding more tools to your belt. It's about strengthening the person who wears the belt.

The Quiet Ways Investigations Go Wrong

Most investigations don't fall apart because someone asked the wrong question. They fall apart because of something quieter, something that happens inside us long before the interview begins.

It starts the moment a complaint comes in. We hear a few details, and without realizing it, our minds begin stitching those details into a story. Not because we're careless, and not because we're biased in any malicious way, but because that's what the human mind does. It reaches for coherence. It fills in gaps. It creates meaning where meaning hasn't yet been earned.

By the time we sit down with someone, we're not entering the room empty. We're entering with a frame, a sense of what probably happened, who might be responsible, and what we expect to hear. And once that frame settles in, it becomes surprisingly hard to loosen its grip.

None of this is intentional. It's simply human.

The Mind as a Story-Making Machine

One of the most humbling truths about interviewing is that our minds are always working ahead of us. They're fast, confident, and eager to make sense of things. Psychologists call this fast, automatic mode of thinking "System 1," but you don't need the terminology to recognize it. It's the part of us that leaps to conclusions, that finishes other people's sentences, that fills in the blanks before the blanks have been filled.

It's efficient. It's comfortable. It's necessary. And it's often wrong.

The slower, more deliberate part of the mind, the part that weighs evidence, considers alternatives, and tolerates uncertainty, doesn't activate on its own. It requires intention. It requires discipline. It requires a willingness to sit in the discomfort of not knowing.

Science-based interviewing lives in that slower space. But the world around us, the pressure to resolve cases, the desire for clarity, the discomfort of ambiguity, constantly pulls us back toward speed.

This tension between fast and slow, between certainty and curiosity, is the quiet battlefield of every investigation.

Why Technique Isn't Enough

This is why technique, on its own, will never be enough. Technique can help you ask better questions, but it cannot protect you from the stories your mind creates before the interview even begins. It cannot slow your thinking when your instincts are racing ahead. It cannot challenge the assumptions you don't realize you're carrying. It cannot keep you from falling in love with your own certainty.

Only cognitive discipline can do that.

Only a deliberate, structured way of thinking, one that notices its own momentum and gently interrupts it, can protect the integrity of an investigation.

And that is where Red Teaming enters the picture.

Red Teaming: A Discipline for Thinking Clearly

Most people in the investigative world have never heard the term Red Teaming. I hadn't either for most of my career. It wasn't part of our training, our language, or our way of thinking. And yet, once you understand what it is, you start to wonder how we ever worked without it.

Red Teaming began in the military and intelligence communities, not as a tactic, but as a safeguard against the very human tendency to believe our own stories. When the stakes were high, when lives depended on the accuracy of an assessment, leaders realized something uncomfortable: the biggest threat wasn't the enemy. It was their own certainty.

So they created a practice, a role, and eventually a discipline whose purpose was simple and radical: to challenge the dominant interpretation before the world did.

A Red Team's job was to slow the momentum of a plan, to ask the questions no one wanted to ask, to imagine alternatives that felt inconvenient, and to protect the decision-maker from the quiet gravitational pull of groupthink. It was a way of thinking designed to keep people honest, not morally honest, but cognitively honest.

And when you strip away the uniforms and the acronyms, what you're left with is something profoundly human: a structured way to interrupt the stories our minds create too quickly.

That's why Red Teaming belongs far beyond the military. It belongs anywhere human beings make sense of other human beings.

It belongs in interviewing. It belongs in leadership. It belongs in wellbeing and resilience. It belongs anywhere the mind's first interpretation is rarely its best one.

Because the truth is, the same cognitive vulnerabilities that can derail a military operation can just as easily derail an investigation, a conversation, a relationship, or a moment of self-reflection. The same shortcuts that lead analysts to premature conclusions are the shortcuts that lead interviewers to misinterpret behavior, misjudge credibility, or cling too tightly to an early frame.

Red Teaming gives us a way to slow down that momentum. It gives us a way to notice the story forming in our minds and gently loosen its grip. It gives us a way to step outside our own perspective long enough to see the situation, and the person, more clearly.

And perhaps most importantly, it gives us a way to build ourselves.

Red Teaming is not about being skeptical of others. It's about being humble about ourselves.

It's about recognizing that our minds are powerful, creative, meaning-making machines, and that without structure, they will run ahead of us. It's about creating a discipline that protects our thinking, our decisions, and the people who depend on them.

That's why this series exists. Not to introduce a new technique, but to introduce a new way of being an interviewer, one that is more deliberate, more reflective, more grounded, and more resilient.

Red Teaming is the bridge between science-based interviewing and the deeper human work of thinking well. It strengthens accuracy, but it also strengthens wellbeing. It improves investigations, but it also improves people.

And once you see it, you can't unsee it.

Where We're Going Next

In the articles that follow, we'll explore the two minds of the investigator, the predictable ways thinking goes wrong, and the tools that help us challenge our own certainty. We'll look at how Red Teaming strengthens investigative mindset, and how it can be woven into planning, interviewing, and review.

My goal is simple: to help build interviewers who think clearly, regulate themselves, challenge their own certainty, and approach people with curiosity, humility, and discipline.

Because the future of interviewing isn't just better technique. It's better thinkers.

Like much of what I write about, training is a first step. It is what has moved me beyond my blind spots, at least some of them. I can provide the training or recommend providers teaching science-based techniques. Do your research, find the right provider, and maximize your training dollar investment. If you are a practitioner or a leader, don't settle for the same old legacy-based methods that have no empirical evidence supporting them. This is not the time to "do it as we have always done it." If you are in leadership, you carry the same responsibility to know and apply these standards and to find training content that maximizes your team's effectiveness and accomplishes your mission.

Anderson Investigative Associates is positioned to custom-tailor science-based training to your specific needs. If you have any questions or would like to discuss the subject of this imperative transition, or any training need, please reach out. Additional issues pertaining to interviewing, auditing, and investigations can be found in other blogs and videos that we have produced and are contained in most blocks of instruction that our company presents.

If you have additional questions, comments, or an interview topic you would like me to address, just let me know. In the meantime, be well, stay safe out there, and start investing in a transition that is ethical and effective. It will improve everything you do. It's time to improve your interviewing and communication skills, not just in your work, but throughout your life. If you need help getting ready, I know who could help.

And remember: Curiosity over Certainty. Every time.
