Right. So that's a different way of analysis you used here in this case right? That is exactly how you should think. Critically.
Apply the same thing everywhere.
Another problem in your argumentation about Newton. Let me explain it as concisely as possible with a question to you.
In the beginning of the 20th century there were far more atheists in the world than lets say in the 70s. So given that within the last 50 years science has expanded its wings exponentially, and it was much much more primitive in the beginning of the 20th century, why do you think atheism grew so much like magic? Is that more information that today?
I suspect because there has been more critical thinking in the sense that others have brought up these questions. Not to champion any individual thinker, many have questioned what before was accepted as true. Information in the sense that the questions are out there for more to consider.
Whether you agree with folks like Dawkins, Dennett or Harris or not, people are more aware of the type of questions being asked.
Back to the study itself, it is a bit dated. Didn't find anything newer. It was more a conversation starter than claim to defend.
I don't think every scientist is necessarily interested in critically questioning their faith. I suspect it is more the influence of peers with are more likely to question such beliefs.
None of that really answer the real question though.
Can our belief in God, whatever that happens to be survive critical examination?
That would probably depend on how critical it was.
