I am not a scientist but when someone tells about causality, often it is about causality in her mental model. Even without speaking of quantum weirdness and all that stuff, in real, macroscopic life, it is often difficult to be sure of causality. Physics experiments that are conter-intuitive are not rare, for example the Sagnac effect: https://en.wikipedia.org/wiki/Sagnac_effect https://en.wikipedia.org/wiki/Sagnac_effect
