Please keep in mind that there is no guaranteed way to protect you from being lied to, but you can know the precautions and educate yourself about these. This information can help you decide if you should trust someone or look more into that person. This website also goes over the basics of lie detection that law enforcement uses and also when trying to get a job at many large corporations.

This may be done openly with a machine but you also can never realy know when someone else is trying to decipher your thoughts and intentions for them. It's good to know how these work so this website will cover not only how this is done without machines but also how it is done using machines.

Please enjoy and use this information the best you can.
