interesting thread. Thanks to Dr. Pam for bringing previous domain-specific knowledge to it. When encountering a body of papers on a subject you're not familiar with, you're always limited in your ability to read them critically even if you have time to spend/waste. And Dixon's comments have been interesting and well-structured as they so often are. Varda clearly has a lot of knowledge in this area and is well able to make her case.
With Independent Eye adding his fresh perspective, and with the lack of random rants it's drawn, this maybe will serve as a canonical example of a perfect Wacco thread. One thing that typifies this site is the attention paid to the scientific validity of claims. So lots of "evidence" is given and there's discussion of whether scientific logic is even being applied. This one finally is veering toward whether scientific validation is even necessary. Clearly to most people it's not. Even the most analytical of us are going to make personal decisions by how we feel -- that's been scientifically validated! So Conrad's bringing art into this is illuminating.
It's true that it's sometimes dangerous when people make decisions that fly in the face of the best knowledge, and not great when people make scientifically indefensible claims, but that's how us monkeys operate. There are a lot of contributions these semi-scientific (pseudo-science has become pejorative) activities make in the world. Sure, they do harm too. What doesn't? For example, vaccines do hurt some people. Even though most anti-vaxxers aren't shaping their feelings by scientific analysis, on that one point they're right. But we're better off with vaccines in the world. I suspect, despite a few railroaded criminal defendants who are wrongfully convicted (if any actually exists) graphology has enriched many people's world. As does art. As do puppies.
