Why does the US versus THEM mentality persist between those who favorably view the ramblings of Jack Hershey and others less favorably impressed by him ? I believe its because of two diametrically opposed and mutually exclusive views of the nature of reality. Hershey expresses his view of reality in his writings here and by reference to outside works. For example , he favorably recommends a movie titled "What the Bleep Do We Know ?". In Hershey's worldview there is no objective reality, just the one created by the individual. In this worldview backtesting is useless because it was created by someone else and hence from their universe and has no bearing on one's own universe. Likewise Hershey can give no rules to trading or even show his trading because he believes any results and any methods are unique to the individual. At best he discusses transference which is a sort of reality seeding from which an individual may hope to sprout his own similar universe. Hershey sums up this worldview as BE DO HAVE. The opposite worldview is that objective reality exists.Usually those holding this worldview believe that reality exists regardless of ones own feelings or thoughts about it and that it is a more or less common reality which everyone existing shares. In this worldview, individuals may use the same exact rules in trading and achieve the exact same out come, execution problems notwithstanding. That is why proponents of this view want to see the results obtained by Hershey and often use backtesting. They believe that reality is not affected by their thoughts about it so much as their actual actions within it. No amount of mystical musings will dissuade an objectivist and no amount of reason will dissuade the mystics. So that leaves the two permanently at odds.
