this is the modern version of Scientology’s free e-meter reading
I actually have a fun story about that. They once had a booth on my college campus so just for fun I let them hook up their e-meter to me. I was extremely dubious that this device did what it claimed, but just for fun to mess with it I tried as hard as I can to think calm and relaxing thoughts. To my amazement, the needle actually went down to the “not stressed” end, so I’ve gone from thinking that the e-meter is almost certainly bunk to thinking that it is merely very probably bunk.
That isn’t the funny part, though. The funny part was that the person administering the test got really concerned and said that the device wasn’t working properly and had me take the test again. I did so, and once again the needle went down to the “not stressed” end. The person administering the test then apologized profusely that the device was clearly not working and said that they nonetheless recommended that I take their classes to deal with the stress in my life. So the whole experience was absolutely hilarious, although at the same time incredibly sad because I strongly suspect that the people at the booth weren’t saying these things in order to deceive me but because they were genuinely true believers who were incapable of seeing the plain truth even when it stared them in the face.
