Piketty's Capital in the 21st century would be an example of something in between. His main hypothesis is that unless there is some intervention wealth accumulates until almost all of it is concentrated among just a few. He uses lots and lots of statistics to support his theory. He tells us that it happens but is unable to tell us exactly why.

Is that really any better though. Unless those statistics are shown to have a predictive effect on money flow, he’s just publishing something to fit a model and metaphorical high fives are thrown around by people that already agree with the hypothesis.
