While I agree that the % difference between specialists in philosophy of religion who favor theism and the large majority of philosophers who favor atheism is not surprising, I would be surprised if the justification for the difference did not split down 'party lines'. I suspect that the specialists in the philosophy of religion would overwhelmingly select (i) and (ii), while the target faculty population would overwhelmingly select (iii) as being the main reason for the specialist difference. One wonders if this would be due to the polarizing nature of the question, itself, or if it would be due to the mere fact that the question posed is one of the few in philosophy that every philosopher has (at some point) wrestled with?

My guess is that the specificity of the distinctions made in the questions regarding decision theory, philosophy of physical science, and philosophy of mathematics would explain not only the differences, but also what I assume would be a general unanimity among the target faculty population, along with the respective specialists regarding the justifications involved in (i) and (ii), as opposed to (iii).

I'm curious as to what others think on this.
