It's irritating when the proponents of scientism demonstrate that they don't even know how the discipline they're holding up as the be all and end all of human knowledge even works.
This is the sad result of specialization. You can have people who are smart, even brilliant, in their field; its importance to them almost necessarily warps their ability to understand things comprehensively. In this case, many of those in the material, physical, and biological sciences may be geared to think of problems and questions only in the terms they are programmed to think in.
