'll comment, since I am rather opinionated at times.
There was a study done a few years ago on, I believe, ESP and how one group of scientists got one outcome and another group, got a differing one, using the same parameters. How could this be? To make a long story short, I think the answer was in the observation(s) of the controlled groups. They seem to skew in ways of belief by the observers. I have no real idea if that is what happened here, but it is a start, especially when you get 2 different outcomes.
Sometimes, some observers want or lets say have their intent set on an outcome and read the actual data in a way that skews the outcomes in their favor, so they can keep on doing the work they love. Not saying they do this deliberately or are bias. Just that sometimes, like loving someone, we cannot see the forest for the trees, If you know what I mean!?
Science does not always have all the answers and is not the greatest at seeking the be all end all, but it is all we have in regards to certain rules and regulations of the universe.
So don't give up on it, otherwise all you'll have is mysticism and not that it is wrong, it does not always answer everything to your satisfaction either. IMO.
As far as training goes and science, I tend to agree with Dr Ken, that most of it is bullshirt, or the application thereof, since it seems to take away from or does not allow for the human minds interaction.
In short, trying to measure "scientifically", how we would all respond to say a 5x5 protocol, does not take into account, yours or my attitude, determination, focus or any other mental aspect that cannot be put under the microscope or measured.
