You can find a criticism of _The Structure of Scientific Revolutions_ in _The Fabric of Reality_. I think that book is (significantly but not entirely) mistaken. One reason is the book can be seen as offering historical laws like Marx, which certainly aren't laws of physics, and don't follow from the laws of physics, and aren't scientific, and have no good reason that they must always be the case in all cultures. BTW Popper criticizes historical laws in _The Poverty of Historicism_ as well as more briefly in other books including C&R. This is something of a side note in any case. tSoSR says people are prejudiced and emphasized new generations of people as important to progress. Popper mostly talks about how knowledge is created, not who creates it. So, his focus is different, and less psychological. If only the younger people are creating knowledge, that's perfectly compatible with most of what Popper says about how (anyone) can create knowledge (via fallible, tentative guesses, and criticism and subjecting ideas to severe tests).
