Interesting piece with a sting in the tail!
When Popper suggested that liberal democracies could legislate small changes in the societal structure, evaluate the results and either repeal or retain the changes he was arguing against utopian views and for such a society. As such it was a significant advancement in thinking about societal changes and a sensible argument against all utopian schemes. Unfortunately, Popper was naïve about the ability of governments, even those of liberal democracies, to evaluate the results of their actions and to learn from them.
