In econometrics, people have gone madder than that. They take two data set and run tests to see correlation between the two - without thinking about any causal relation between the two. They do so because of their adherence to logical positivism which is nominalistic and denies the study of unseen/unobservable. Hence, they look at data and not what lying beneath it, the 'reality', the unseen. (See Methodological Mistakes and Econometric Consequences.)
Perhaps that's why we say: No god but God. Denying everything else first to confirm the Unity of God.
I just had a flash of intuition that above 2 paras imply in some way the latter.
