In this week’s WZ / IAI interview and interrogation training tip, Dave Thompson, CFI, talks about the issue of confirmation bias.
Often, as investigators, we think we’re doing the right thing in searching for the truth, but we sometimes fall victim to having confirmation bias. Sometimes, due to someone giving us an anonymous tip or piece of evidence, or even due to behavior we witnessed during an interview, we as investigators make up in our minds that the subject is guilty. That’s not the right way to do an investigation. We need to let the facts speak for themselves.

What happens when you have confirmation bias is that you make up your mind what the end result should be, and ultimately conduct an investigation to prove your theory versus to prove the truth.
Think about that during your next investigation. Reflect back on some other interviews that you’ve done. What really came first? Did the facts and evidence really prove that the subject was guilty, or did you just decide that they were?
Challenge yourself to make sure that you go into every investigation without a bias and with a clear intention to look for the truth. Look for reliable information, no matter which way it leads.
