Talk:Lie detection

From Wikipedia, the free encyclopedia

I have just suggested that this article be merged into Polygraph - though truthfully, I liked the earlier redirect and am considering reverting to it. This page seems to consist only of information that is better covered in other locations. Thoughts? Magichands 21:27, 8 March 2007 (UTC)

This article needs a lot of upgrading. First, lie detection is much more than using a polygraph. In fact, the polygraph isn't a lie detector, it's the person who analyses the graphs that is the actual "lie detector".

Secondly, there are other ways. Namely; body language analysis, micro expression analysis, and statement analysis.(And probably a whole lot more)

The polygraph is categorized as a body language analyser.

When lying you act different at that spesific point, and it causes changes in posture, the size of the pupils might change, heartbeat, voice-tone and use of language differs etc. from the rest of the ordinary way of act. Thats what body language analysis and statement analysis deals with. Micro expressions is sudden movements in facial muscles lasting for a fracture of a second. Analysis of this is ofthen done by replaying interviewing-tapes over and over again at slow motion. Perhaps Stan B. Walters should be mentioned here, he has been on TV lots of times on this subject, he is giving lessons on this, as well as being an investigator on this subject.

Statement Analysis is a colder method, analysing the words and sentences of any written statement, written by the subject itself, or dictated. There are involuntary traces of ones real thoughts and intentions in everything we say and write. This method of analysis was invented/discovered by Avinoam Sapir. Should mention him too.

I'm not good at editing articles, but here is some good stuff for background material for those who can. -Jorgen

I would recommend against the merge, since there are so many different kinds of lie detection schemes, it seems useful to have an overview article. -- Beland 17:33, 3 November 2007 (UTC)

[edit] Overview needed

Please help improve this article or section by expanding it. Further information might be found on the talk page or at requests for expansion. (November 2007)

Right now, this article is mostly just a pointer to lots of articles on specific techniques. It would be nice to have an overview of common challenges, comparisons for effectiveness and feasibility, history of various techniques including those with no articles, and also general coverage of how people detect lies "intuitively". -- Beland 17:42, 3 November 2007 (UTC)
