A little change in Emoto’s experimental design would do great things for the credibility of his claims. I recommend the following to ground his work in sound scientific principle:
Eliminate the possibility of the scientist’s bias affecting the experiment’s results by implementing double blind procedures.
Publish the entire collection of photos for all water sample tests that he has performed, not just the ones that support his claim.
Minimize the sources of possible error in his procedures, such as variation in temperature and humidity between sample.
Pay more attention to the time-tested methods of the scientific community rather than disregarding them. Emoto’s research could go much farther if he could interest scientists around the world in testing his hypothesis.
