In chapter two, The Witness on Your Shoulders of The Neuro Revolution, I focus on the emerging field of neurolaw. It's an extraordinarily interesting and provocative area of research that will continue the evolve rapidly in the coming years as new techniques and technologies emerge to help us peer more effectively into the brain as it contemplates ideas, such as lying or telling the truth. Which brings me to the purpose of this blog post.

There has recently been some exciting press around the Josh Greene's work around using fMRI for the purposes of lie detection and the continue skepticism surrounding its use here. As Time's Adi Narayan succinctly put it, "On an fMRI image, at least, the lying brain may look no different from one that's simply contemplating whether to lie."

So with today's technology I would agree, yet, as I argue throughout the book and have discussed here many times, major technological revolutions begin with a 15 year period of technological transformation. During these periods of rapid innovation new tools emerge that radically surpass what was previously believed to be possible. We are only just entering this period. So just because current imaging techniques appear to weak at being able detect deception, don't let this fool us. We must continue to think through the ethical, legal and societal implications of truth detection technologies, because they will emerge, and will transform our system of jurisprudence in many, many ways.
