According to kuhn what causes a paradigm shift?

Answer:
According to Kuhn a (Kuhnian) paradigm shift is a fundamental direction change in science. Caused by doubt.
Kuhn 'softened' his original insights in such a way that they only concerned 'science'. Kuhnian paradigm shifts are shifts INSIDE the main body of science, and don't change life very much (unless life itself became scientific, rational ...).

Kuhn probably did so, because he enjoyed being a famous professor with a lot of priviliges, and had no intention at all to attack science itself as religion.
