Well, I’m beginning to have a change of heart towards Margaret Wertheim. Maybe she’s right. Maybe it is more important to ask why they do it. I agree, we do appreciate the access to information and the new “do it yourself” culture. At the end of the video, she asked if it is unacceptable to have a DIY theory of physics, but it doesn’t matter, and it's only likely to increase. Margaret Wertheim Some of you may think that pseudoscience doesn’t interfere with genuine scientific discourse, and so it’s essentially harmless, while others believe that pseudoscience is harmful at all levels. It does contribute to scientific illiteracy and the public’s gullibility. Do scientists have an obligation to help the public make a distinction between the two? Who knows, maybe someone will come up with some filtering solutions. Hmm…pseudoscience filtering software, not a bad idea.
