I don't know who "most people" are but if you are conflating science with values (I did a quick look up of the definition of "scientism") you are doing it wrong - and it isn't science. This reminds me of a video I watched once. An author named Sam Harris wrote an entire book titled The Moral Landscape that supposedly (I haven't read the book) makes the argument that science can precisely inform our value judgments . A physics professor named Sean Carol confronted him publicly on his views and explained the demarcation between values and science. Each time Sean would pin him down Sam would squirm around and change the topic or miss the point. I don't think most people agree with Sam Harris's view (which from what I've read embody what you are talking about) , but at the same time I don't think most people care about any of this stuff either way. :)
