This may seem like magic, but it is actually based on a person's physiological reactions when they are lying, such as blood pressure, pulse and breathing.
Of course, lie detectors are not omnipotent. There are people who can deceive machines after professional training.
It's just that kind of people are very rare. They only target ordinary criminals, not professional spies.
Tang Ze's choice of the lie detector is actually a good entry point.
First of all, compared to those expensive machines, the polygraph is a cheap device and is easy to operate, and does not require high-end professional technicians.
Being cheap means it is easy to roll out and can be used on a large scale.
More importantly, it is easy to achieve results and it is very straightforward.
The lie detector is actually quite useful for ordinary people. Although there will be a "preliminary check" before the test begins, many people cannot pass this first level.
When you deny seeing the poker card, the machine will directly determine that you are lying. Many suspects will choose to give up resistance and confess everything at this stage.
With this, the results are obvious.
If nothing else, at least it can improve efficiency in many cases.
For example, when dealing with thieves, this thing is definitely a powerful weapon.
Those thieves are habitual offenders, but the crimes they committed are not serious. They go to prison for a few years and then go out to commit crimes again. Many of them are old hands and never tell the truth.
After the theft, the police investigated these people first.
But you can't believe what they say, you can only investigate slowly.
But if there is a lie detector, it will be much more convenient. Under the test, you really have no choice but to hide the truth.
For habitual thieves, this thing is a great deterrent and prevents them from committing the same crime again.
After all, you have already registered with the government office, and they can still test whether you are lying or not, and whether you are panicking or not.
After making up his mind, Tang Ze stood up, took out his phone and called Boss Saitama to tell him about his plans.
And with the support of Boss Saitama, I believe we can quickly convince the higher-ups to implement this plan.
Tang Ze is very much looking forward to this.
