Yackety Yak Will Cost You The Facts

Every profession develops habits. Some are useful. Others survive simply because “that’s the way we’ve always done it.” Investigative interviewing is no exception. One of the most common mistakes I continue to observe is interviewers who believe they must constantly control the conversation by talking. They interrupt narratives before they develop, fill every pause with another question, and mistake activity for effectiveness. The result is predictable. The subject says less, the statement becomes less reliable, and valuable information is often lost forever. The irony is that the solution is remarkably simple: learn when to stop talking.

The Person Doing the Most Talking Isn’t Collecting the Most Information
During more than four decades of teaching investigators around the world, I’ve seen one mistake repeated over and over again. The interviewer asks a question, receives the beginning of an answer, and immediately jumps back into the conversation. Another question. Another interruption. Another explanation. Before long, the interview has become a contest to see who can talk the most. Unfortunately, while the interviewer is talking, the subject isn’t. Every unnecessary interruption cuts short the natural flow of memory and eliminates opportunities for the subject to recall additional details that may never surface again. Good interviewers ask thoughtful questions. Great interviewers know when to get out of the way.

Silence Isn’t Empty—It’s Where Memory Does Its Work
One of the reasons investigators over-talk is that silence makes them uncomfortable. A few seconds pass, and they assume they’ve lost control of the interview. Nothing could be further from the truth. Silence is often the moment when the subject is searching memory, organizing thoughts, and deciding what comes next. Experienced interviewers understand this. They resist the temptation to rescue the conversation. They allow the pause to do its work because they know that some of the most valuable information in an interview arrives immediately after the investigator says nothing at all. Purposeful silence is not passive. It is one of the most disciplined skills an interviewer can possess.

I’ve Seen the Difference Firsthand
Years ago, I witnesses in the interview of an embezzlement suspect alongside two investigators. Then one of the investigators decided it was time to become the “hard guy.” The tone shifted. The interruptions increased. The conversation became more about the interviewer than the subject. Within minutes, the information stopped flowing. The interview wasn’t destroyed because the suspect suddenly became deceptive. Later, the suspect said he had decided to cooperate and was going to provide useful information. It stalled because the interviewer couldn’t resist talking. That lesson has stayed with me ever since. Across thousands of interviews and countless training programs, I’ve seen the same pattern repeated. The investigator who talks the most often learns the least.

Sometimes the Best Thing You Can Say Is Nothing
Investigative interviewing is not a speaking competition. It is an information-gathering process. The investigator’s responsibility is not to dominate the conversation but to create an environment where accurate, reliable information can emerge naturally. Asking good questions will always matter, but knowing when not to speak may be even more important. The next time you feel compelled to fill an uncomfortable silence, resist the urge. Give the subject room to think. Give memory time to work. You may discover that the most productive words you say during an interview are the ones you never speak.

You don’t lose control when you stop talking. You lose information when you don’t.

Choices made in the interview room eventually play out in a courtroom.
