The most effective technique is plain old questioning
I couldn’t believe when I read the stats on lie detector tests. In the movies, on tv and even in the real world, the results of a polygraph are taken as fact and rarely questioned. But their accuracy can be as low as 60%, which is incredible to me. I’ve always just assumed they were the best way to get the truth out. The lie detector results show, that was a lie! There are actually more effective, albeit somewhat questionable, methods for getting the truth out.
Accurate, but ethical?
Active questioning techniques, like the Reid Technique, score nearly perfect in terms of their accuracy. If it’s so much more accurate, then why isn’t this the go-to method for truth extraction? Well, this technique is a 9 step interrogation method, using both confrontation and manipulation to get results, which has also been shown to produce false confessions. Is there really any way of effectively and accurately getting the truth? I want the truth! And I can handle the truth!
Although it seems to be much more accurate, the methods used in the Reid Technique are ethically questionable. Manipulation and intimidation, coupled with hours of intense questioning are a dangerous combination, at risk of producing less than reliable results. Sure, someone may confess, but is it a true confession or were they just bullied into it?
There have been so many instances where a person who confessed to a crime was later shown to be innocent. The scary thing is that those who were eventually proven innocent may just be a fraction of the truly innocent who are sitting in jail for a crime they didn’t commit. There’s really no way of knowing the real number of people who were wrongly locked up because of inaccurate lie detector results or intimidating interrogations. The only thing we can hope for is better advancements in technology to more accurately detect the truth.
