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.
