Granted, the IQ test is boring and doesn't assess the full range of a persons abilities. But honestly! If people could really reliably improve their IQ's 30, 50, 100 points, than this technique would soon spread over the entire world, and become mainstream! As it is 20 pts. is highly significant, but it can be written off to opening up latent abilities in an individuals repertoire of problem-solving- all these participants in the Reinert study began with an avg. IQ 95. 50 pts. absolutely couldn't be written off. The full-range of benefits for Image-Streaming are much more important than just IQ, but IQ is the easiest quantifiable one. If you want to get people impressed with this technique than quantifiable data is the way to go. And, yes, I do practice Image-Streaming...I find it one of the most fascinating, and beneficial, things espoused on this board.
