Just another example of how Organic (clean food) propaganda isn't based in science. I can't tell you how often I hear cooks swear by their redish, darkwe yolk eggs for having some kind of magic properties. Interesting article, good read.
To complicate matters, psychology can play a significant role in the material result when making things. It's like the placebo effect but for the engineer, the cook, the mechanic, the designer etc.
Obviously cooking is about more than the ingredients, they are important, but timing and intuition play a big role, the latter can be undermined if they start without believing in the ingredients... this applies to programming just as much as cooking.
