This is a response to a claim by Sven Ove Hansson to the effect that Poppers dictum that falsification lies at the heart of all pursuit of science has once and for all been falsified by his study of articles published in Nature during the year 2000. We claim that this is based on a misunderstanding of Poppers philosophy of science interpreting it too literally, and that alternative readings of those papers are fully compliant with falsification. We scrutinize Hansson’s arguments (...) as well as giving an overview of Poppers falsification theory. (shrink)

I var tid ar ambitionen att sa mycket verksamhet som mojlig skall vila pa vetenskaplig grund. Darmed utokas vetenskapens domaner, samtidigt som begreppet som sadant forflackas. Filosofen Karl Poppers syn pa vetenskapen ar mera subtil. Enligt honom kan vi ingenting veta med sakerhet, ingenting bevisa, endast falsifiera, det vill saga visa att nagot ar oforenligt med faktiska forhallanden. Det som undandrar sig falsifieringen kan vi acceptera tillsvidare. Ulf Persson provar i denna bok Poppers teori pa ett antal vetenskapsomraden, daribland ekonomi, (...) pedagogik och evolutionsbiologi. (shrink)
