Almost all signal can have most of it's information expressed as a sine wave, but it's the jitter in the wave that has all the 'important' information. There's a fallacy where getting the majority of certain types of information leaves you blind to the important but "smaller" types. I think medicine and personal health is one such domain where this fallacy is abundant.
The weakness of heuristics is that they don't turn into reusable models but vice versa models can leave you blind. The constant disdain for heuristics is a huge weakness of many scientifically minded people IMO.
- ice109 9y ago>almost all signal... this the silliest misinterpretation of Fourier analysis I've ever seen and I'm not going to try refute it except to say that with the clarity you're implying Fourier decomposition applies only to periodic signals (ie saying that a signal that has a continuous time FT "has most of its information expressed as a sine wave would be an egregious exaggeration so you must talking about series expansion and that only applies to periodic signals [and I'm at a loss for how to interpret info about chiropractors as periodic]).
