I read the article, and your post. The "extremely simple concept" is amazingly easy to understand but very hard to accept because it fails to account for the mindboggling effectiveness of science (cumulatively over centuries), and because it fixates on largely irrelevant features while ignoring essential ones.
The scientific thinking that works has _very little_ use for faith. Thinking in terms of degrees of certainty, caveats, probabilities, and so on is extremely useful. Of course one has to accept a few premises to be able to do anything (e.g. "reality can be understood to some extent"), but this is so far removed from the religious ideas of faith or the colloquial usage of faith that it is an observation of very little value.
And, as a layperson, the _only_ thing you have to do is adopt the simplest parts of a scientific point of view--e.g. to be able to think in terms of degrees of certainty--before the difference between science and religion becomes profound. There are plenty of venues where scientific knowledge is distilled down from the original research to a point where interested laypeople can understand if they care to (e.g. Scientific American, science column of many major newspapers, etc.). Highly disinterested people do, of course, have to take the word of scientists on faith, but that's again an observation of very little value. They have to take _everything_ on faith that they don't pay attention to: science, religion, law, mathematics, you name it.
