Why must I always be the realist? Portable fMRI units for "lie detection"
Let me point out that in the States, fMRI machines are as we speak being certified (how? by what authority?) as lie detection machines for legal investigations. They are labeled 100% reliable. No, you don't get an opinion about it.
Now I see, coming with the speed of a crashing satellite, field fMRI caps to be slapped on the heads of "criminals" for instant lie-detection.
Don't let it happen.
