I honestly don't think they clock in at 9am and mutter 'right, I'm not going to be religious for the working day'. As I understand things, it's more of a means by which one lives one's life. Joe Q. Scientist attempting to cure cancer can, and probably does, achieve some very good, reproducable, scientific results whilst asking guindance from, and giving thanks to, his invisible friend. He might even cite said friend as his motivation for trying to help out his fellow humans, on scientifically-flimsy grounds such as 'love thy neighbour', or similar. It might not form a crucial part of the work he does, but his religion is still going to be there in the room with him as he goes about he serious business of Science. Which more or less means it's not really that incompatible at all.
