Prefer not to Receive the Early Results Email

I would prefer the "Send me early results" checkbox default be set to unchecked. Is there a way to turn it off as the default?

I realize people can uncheck that option in each email, but we have various staff members sending out emails and it's unlikely that we could get staff to remember to uncheck it each time. 

The early results emails are not useful and add another email to a group inbox that must be deleted.
