Many scientists are atheists or at the very least not strictly religious. It seems that you currently have to believe in God to be elected. Is this keeping many of them from even running?
I read this sentence three times before I figured out where the error was. The word you want is defer, not differ.
Arkansas, Article 19, Section 1:
No person who denies the being of a God shall hold any office in the civil departments of this State, nor be competent to testify as a witness in any Court.
That no religious test ought ever to be required as a qualification for any office of profit or trust in this State, other than a declaration of belief in the existence of God; nor shall the Legislature prescribe any other oath of office than the oath prescribed by this Constitution.
No person who denies the existence of a Supreme Being shall hold any office in this state.
The following persons shall be disqualified for office:
First, any person who shall deny the being of Almighty God.
No person who denies the existence of a Supreme Being shall hold any office under this Constitution.
No person who denies the being of God, or a future state of rewards and punishments, shall hold any office in the civil department of this state.
The second link indicates that the study found out that about half of those scientists surveyed express a religious identity, yet only 15% say they are always in conflict. My guess is most of those in the middle count themselves as 'deists'.
As an earlier poster has said, being a scientist doesn't make you any less human and subject to everything that goes along with that - emotions, irrationality, ego, and so on.
