Practiced Liars

The most difficult group of people to detect lying from is career criminals; in a funny twist of fate they are also the best at detecting lies (without training).

Why is this?

Practiced liars, the people who lie every day, the nonverbal effects of deception simply wear off. It is where the phrase comes from, "You were living you life as a lie."

Think of the unfaithful husband who carries on an affair for years or decades, from the first day it started he was living a lie. As time moved on, it became easier for him to tell the lies he told to maintain his double life.

Con men do not simply snap and start stealing. They start small, and as lying becomes more practiced, it becomes easier, and more profitable.

The same goes for the spy or agent who first receives deceit training, then they develop and hone those skills.

What does this mean for us? Well the first lesson is it is better to catch them early on in their lie. Secondly, we need to continue to develop our skills and technologies.◦
