Fascinating book that studies how perception works and comes up with some unexpected conclusions.

This is a subject that's fascinated me for a long time, so I did find a few places where I was skipping past stuff I already knew, but that just shows how well grounded it is. The important thing with this book is that everything they say is backed up with experimentation. In fact one of the cornerstones of the whole thesis is that you can only find out how something works by testing it with controlled experiments, and the biggest misunderstandings about the way perception works are down to incorrect assumptions.

The whole line of research on which the book is based stems from a single experiment that gave an unexpected result - that the more unusual a thing is, the less likely you are to notice it.
