Which Interview Technique Works Best?

One question I’m frequently asked is which interview and interrogation technique works the best. The best answer I can give is whichever technique you used when the subject confessed. Although that answer may sound vague the reality is that the response is very accurate. There is no uniform method or technique that will be successful in every interview situation. As we discussed in the June issue, the successful interviewer is the one who learns how to adapt to the unique personality and behavior characteristics of the subject that happen to be interviewing.

To be a little more specific, we can refer to several scientific studies that have observed, documented and analyzed several hundred investigative interviews. The findings of these observational studies are quite interesting in that they report that there are interview and interrogation tactics that appear to regularly be most successful. In fact four approaches seem to consistently productive:

1. Appealing to the subject’s conscience.
2. Identifying contradictions in the subject’s story.
3. Use of praise or flattery.
4. Offering moral justification and / or psychological excuses.

It is very interesting to note that these four approaches appear to coincide very well with the four dominant personality type interviews that we use in Practical Kinesic Interview & Interrogation®.

The next time you are preparing for an interview or interrogation, mentally create four separate dialogues you can have with your subject using each of these four approaches. Once in the interview room, make an assessment of the most likely personality type of the subject you are interviewing and use one of the four dialogues most appropriate. You should find you’ll get positive results must faster and have a higher admission and even confession rate.
