I get a feeling that this holds only for physical books and perhaps not as much for digital books. i.e. Owning more Kindle books doesn't necessarily give you the Dunning-Kruger compensating force (I'm guessing) because these aren't necessarily in your face frequently enough. Personally, I have a mixed physical-digital library. My physical library is packed with books that I think will stand the test of time (roughly speaking) and which I have truly long to read and re-read. I use the digital library for things that I think are more in the "this will pass" category (also roughly speaking, as I only own a digital copy of some real gems like Ousterhout's "philosophy of software" book). Curious about the distribution others use here.
