Craig Callender in the New York Times:
Not all mischaracterizations of Heisenberg’s principle are as innocent as Eppes’s. The film “What the Bleep Do We Know!?” uses it to justify many articles of faith in New Age philosophy. Asserting that observing water molecules changes their molecular structure, the film reasons that since we are 90 percent water, physics therefore tells us that we can fundamentally change our nature via mental energy.
This gets at one of the perennial problems facing technical experts: in explaining a concept to a non-expert there’s always a trade-off between being understandable and being rigorous. It’s easy to imagine how a high-level explanation of the uncertainty principle could have led someone to believe that the point was that “science can’t tell us everything”, leaving the “gaps” to be filled in with this New Age dreck.
How do we counter this kind of thing without making a physics degree compulsory? Probably the best we can do is to give everyone a broad-based science education and the critical-thinking skills that will allow them to identify these ideas for what they are: bullshit.
