How to cheat the lie detector

Source:  http://www.wikihow.com/Cheat-a-Polygraph-Test-(Lie-Detector)

My Topic: The lie detector is not accurate to use in the court as the evidence.

What I hope to learn from this source: I want to find that there are some articles to teach the way to deceive lie detectors. 

Notes.

There are four methods to deceive:

1. Prepare Well in Advance

2. Be on Your Guard

3. Learn How to Recognize Question Types

4. Apply Polygraph Countermeasures

>>>>Final Thoughts: I want to find some research which shows the lie detector is not accurate because we can even deceive lie detector. And I found pages about teaching the method of deceive lie detector. According to this article, if we follow four steps, normal people like us can deceive it! So it is not accurate.

But I found later that this information from 'wikihow'. Wikihow is similar with the Wikipedia as everyone can register their knowledge. And I determined it is not accurate for my research. Therefore I didn't use it.
