As are many people, which tells you why JH's "double blind" test was not at all double blind. Cosmetically disguising bikes does not make it a double blind test. By his own accounting, two of the three riders in the test could tell the difference between the bikes by the way they felt, i.e. they
knew which bike they were riding at any given time. If you combine that with the fact that they knew what effect they were testing for, it is not at all surprising that they observed some positive results. (I also wouldn't be surprised if the rider that recorded the remarkable 12% increase in power was JH himself.)
I can't find the post, but I'll paraphrase something written by someone else on this forum in a previous thread:
JH is a brilliant marketer, but his scientific methodology is poop.
