True-true-false reasoning (psychology)

True-true-false reasoning is a psychological method for gauging what reactions and emotions are associated with 'true' responses and what reactions are associated with 'false' responses by using a series of questions that answer 'true, true, false' (they may alternately be made into 'false, false, true' or some other variation).

Usage
Correct usage is by finding out three facts about the individual (or more) that you know for sure are either 'true' or 'false'. A true-true-false attack asks three questions in series where the individual, if answering truthfully, will give a baseline 'tell' as to how they act when something is true and when something is false. The false is left until last because the build-up of two truthful response questions misleads the subconscious into anticipating the third as being a truthful response question, so if it turns out to be false, it will react more hestitantly allowing for more lead time on determining the 'tell' for when something is negative or false.

There must be a repeat of at least two, if not more, of the same answer type. So two true response questions will allow you to gauge what true responses have in common regarding subconscious cues.

For example, an individual doing true-true-false reasoning would ask Quack the duck, 'are you a duck?' (Quack has to reply affirmatively), 'do you have two legs?' (Quack, unless he less than two legs, has to reply affirmatively), 'Do you have a bank account?' (Quack, as a duck, cannot own a bank account, so he has to reply negatively). If Quack lies on any of these basic questions, you will be aware of the 'lie tell', if he answers truthfully, you can distinguish a true from false reaction set and thus use confirmation to determine.

Problems
True-true-false reasoning requires the individual be at least consistent. Individuals who give different reactions can prevent any sort of target lock being established. However, individuals who do this will at least give away they are aware of your intentions of gauging their reactions and thus may have an understanding of the methods (which means you are aware enough to treat them with caution when depth-charging etc). However, it's not possible for the human subconscious to maintain inconsistency for long and people often reset to default, especially when caught off-guard. True-true-false may be engaged over time rather than immediately (however immediately allows for more consistent and thus more accurate results).
