Is that so?

Yes.

The locals will work up the case.

And polygraph, you know, it's controversial.

It's the best mousetrap we got.

If you tell me a story, two truths and a lie, or whatever you tell me a story, there's probably a 60% chance I'm going to be able to tell if you're being truthful or not.

And I've been doing this my entire life.

The average is about 50%.

It's almost a coin flip.

So we suck at this.

So what makes us better?

Polygraph.

But polygraph needs to be used on the right time, the right place, on the right person, and in a very limited scope to help shape an investigation.

When it's used willy-nilly, just let's test everybody, let's test everything, that's when you get false positives, that's when you get false confessions, and that's what puts us in a bad spot when it comes to polygraph.

So we use it with our applicants, and then we also use it in our criminal realm.

So let's say, for instance,

I was working a case in Illinois, and this is where confirmation bias comes in, is I'm very careful about asking the detectives, hey, what do you think?

Because a gut instinct is good, Matt, when you're walking down a street in Tampa late at night and you hear something knock over a bottle, right?

Like, what's going on?

Your gut instinct is run, fight or flight, whatever the case may be.
