See? This is exactly why i end up jumping ship. I was intrigued by this article, got to here, and no find no reason to continue.

When two waveforms of the same amplitude collide, the amplitude can double… or completely each other out (this is how noise canceling headphones work btw) .

It would be better if the correlations were focused on and let people who actually do understand physics and statistics focus on cause and effect and underlying mechanisms of function.
