You speak as if scientists can and do turn off their humanity, like flipping a switch, when they put on that lab coat.
I am certain you know, or at least should know, the technical term for it is "methodological naturalism", which, yes, does literally mean: we put on our naturalism coats at work, but take them off to go home for prayers with our family before dinner.
Methodological naturalism is starkly contrasted to philosophical naturalism -- also known as ontological naturalism, or metaphysical naturalism.
In philosophical naturalism we never do take off our scientific coats, never say grace at dinner, and indeed never even go home, since home is a product of traditional values which we gave up to embrace philosophical naturalism.
You just must "get" the concept of methodological naturalism in order to understand where today's science came from, and what it should be now.
