Occasional Musings

An interesting review of work from Imre Lakatos on the idea of  how theories/science fail? A crucial aspect for science to be progressive. Also check works from Karl Popper, Thomas Kuhn and others.

Here is an interesting excerpt from the article …

“…  Lakatos judged a programme to be ‘progressive’ if it is both theoretically progressive – the hard core plus auxiliary hypotheses predict novel empirical facts – and experimentally progressive: at least some of these novel facts can be tested. In contrast, a programme is ‘degenerating’ if it is theoretically degenerating – it doesn’t predict any novel facts – or it is theoretically progressive but experimentally degenerating: none of the novel facts can be tested.”

“….Lakatos merged the distinction between science and non-science, and between good and bad science. If a programme predicts nothing new or its predictions can’t be tested, then it is bad science, and might be degenerating to the point of pseudoscience. Empirical tests serve to refine the auxiliary hypotheses and a programme continues to be progressive for as long as new facts are predicted and new tests are possible. A scientific revolution occurs when a dominant programme has completely degenerated and is unable to respond to accumulating anomalies – creating precisely the crisis of confidence that Kuhn anticipated – until it can be replaced by an alternative, progressive programme. But, according to Lakatos, when the time comes, a revolution is driven by logic and method, not irrational mob psychology: ‘the Kuhnian “Gestalt-switch” can be performed without removing one’s Popperian spectacles’.”
