It's all about money& the scoring of America..
I might the only one here that used to write code but the query process is an addiction looking for value and then looking for money. There is value in data but must be used correctly and average consumers gets duped in marketing at times and you end up with broken models like the Bloombert Big Gulp idea and he didn't know where to stop when the model was failing and same thing in healthcare as people are duped and push failed models that won't work, for the sake of making money. I have been calling it an epdidemic in the US for a couple years now as my data mechancis logic mixed with years in sales combines and it's crystal clear. The executive at the hospital who's been duped by Axiom and Mastercard is good example of danger duping out there.
Here's a nice Quant I communicate with, she'll tell you the same thing and it was a guest post from outside of healthcare..bonus reading at the bottom where Axciom decided to crawl out of their shell and address me on Twitter too:)
The curation of videos at the Killer Algorithm page by people smarter than me will help you figure some of this out so you don't get duped as often, happens to all of us.
Heck I put it out there for consumers and banks reading it like crazy. Long and short you can't sit there for profit and shove a broken model down people's throast for the sake of making money as people don't work that way.
