Actually, a lot of the time it gets the results that the people running the test are looking for. Whether it actually gets to the truth is a kind of different question.

That's right. The way it's portrayed in film and TV is quite wrong, actually, because it's kind of portrayed as this back and forth between the investigator and the suspect. But yes, actually, the way that the test was originally designed was, yeah, these very, very slow...

yes or no questions repeated multiple times over the course of several hours the suspect gives yes yes or no responses because the the point is you want to minimize the difference between the control questions which are irrelevant to the crime and the target questions which are about the crime so you want to you want the suspect to be sitting as still as possible to reduce interference so you don't want them to be spinning out long sentences and things like that you want to

keep the differences to a minimum so that when they do lie, it shows up on the chart. Or at least that's the theory anyway.

Yeah, that's right. It's just somehow become sort of embedded in the justice system. And I think a lot of people have debunked it. It's been debunked by numerous academic studies, government reports, expert analysis on several occasions, but it just sort of refuses to go away. And I think that's probably something to do with human nature, right?

drawn to this idea that a machine can reveal the truth, right? Especially in a time when truth is so difficult to find. I think this idea that there is a machine that can do it for us is still quite compelling.

I appreciate it.

I appreciate it.

I appreciate it.

It's not just a faster version of our current computers. It's a fundamentally different device that basically takes advantage of some weird properties of quantum physics to do things that current computers can't do. So instead of using bits, which are ones and zeros, like a normal computer, a quantum computer uses what are called qubits.
