I've been reading the various arguments about the body scan machine and so forth. One of the main arguments I hear is "It's fast and quick and it allows me to get on with my day."

If someone invented a brain scan machine, basically something which you walk through and it scans all your thoughts and ideas - and all this will take less then 2 seconds, would people prefer using that machine?

Let's say there's two lines, one for normal screening with the X-Rays, Metal Detectors, Body Scans, Pat downs etc and a Brain Scan Machine. Let's also say the Brain Scan has no a 30 second line and the normal screening has a 30 min wait, which one would people choose?
