The POLYGRAPH System

What others are saying about 'The POLYGRAPH System':

Richard Osterlind: Bryn and I were talking on the phone, and neither one of us could believe it is over 20 years that we have known each other! I have always thought extremely highly of his material and have featured some of it on my videos. It’s been awhile since Bryn has sent me anything new, but then 'The POLYGRAPH System' arrived! It is wonderful, and let me tell you why!

As its name implies, you duplicate an actual lie detector test anywhere and at any time. The only props you need are a quarter and a ring, or any two small items. (Bryn offers other ideas in this 40+ page book) The person chooses to to be a "good guy" or a "bad guy" and hides the coin and ring. With a few simple questions (actually just 3) you are able to tell him where each article is, even if both are in the same hand, and whether or not the person is a good guy or a rotten criminal! It’s dirt simple to learn and never fails. None of the standard type ruses are used and everything is direct and logical. It really is that good!

I love it when the Mentalism is in your head and it’s only you and your spectators. That’s what you have here. Bryn uses it all the time as an informal demonstration of his unique power as a human polygraph. When I read it I immediately saw how good it was and began working out my own presentation I will use at my own shows. I won’t tip my idea, as this is a priority item going into my own private engagements, but I will tell you this much: It involves 2 spectators at once and a good cop/bad cop presentation!

This is real professional Mentalism that you will love doing. You will have the secret down in about 5 minutes and the presentation, as Bryn explains it, in a couple of hours. Then you will be ready to go at any time for any size group. Yes, it could even be done on stage. 

Guys, buy this! Trust me; you won’t regret doing so for even a moment! This is REALLY GOOD!

Kenton Knepper: "Bryn: Applying 'The POLYGRAPH System' to the Which-Hand effect with two items is totally new. Unlike most routines using mental work to keep track of the situation, this one is very easy, and is not as mentally challenging to pull off as most "propless" methods. I appreciate that.

I like this a lot, and can see it being VERY well received in a mentalism performance. This is fun and interesting, with a different twist in method, too. That says a lot! Congratulations! - Kenton"

From the mind of Bryn Reynolds, acclaimed author of the mentalism eBooks The Safwan Papers and The Logar Scrolls, comes an elegant breakthrough in propless mind reading.

For decades, the propless "Which Hand" genre has been a staple for the modern mentalist. However, traditional methods often require physical tells, dry logic puzzles, force awkward physical adjustments, & asking nonsensical & unrelated questions.  Often the instructions to the participant are confusing.  Even after all that, you may be able to track a single item’s location, but not know for sure if they are a liar or not.

Those days are over. "The POLYGRAPH System” is now on the case.

Imagine being able to track the location of TWO items...with precision....and knowing 100% if they chose to split the items, or put both in a single hand....and knowing with 100% certainty if they chose to be a liar or truth teller. 

Here is the effect:

You give a coin and a ring (can be borrowed) to a participant.

The coin is designated as "stolen treasure" and the ring is designated as your "miniature lie detector."

They secretly put either item in either hand, or BOTH ITEMS in ONE hand. They also secretly decide to play the role of a liar ("hardened criminal",) or a truth teller ("honest witness".) You play the role of a seasoned criminal investigator; a human lie detector, if you will. A one-man POLYGRAPH.

You ask 3 thematic "YES\NO" questions,  and then know everything: whether or not both items are in the same hand, the location of the coin, the location of the ring, and if they decided to be a liar or truth teller. All with 100% certainty, and no equivocation  or ambiguous statements. The method is simple and very unique. 

-NO gimmicks, math or physical tells. 

-NO equivoque or ambiguous statements. You really DO know everything with 100% accuracy.

-The 3 simple questions you ask are relevant to the plot of the routine.

-You can ask additional, thematic, "decoy" YES\NO questions and also know those with 100% certainty.

-The System is scalable: the method can be used for other routines.
