I don't know that anyone conducts scientific research in order to reach a logical conclusion about which god is real, because most people that value both scientific research and logic don't believe in gods.
I don't have the numbers in front of me to back this up, but I don't believe your claim is true. IIRC, a majority of scientists believe in some sort of god. It may be merely a god who started the big bang and then let the universe go, like a wound up clock, but they believe in
something.
