Several times I read or heard about the claim that there is a discrimination against theists in academia by atheists. For example the german newspaper ZEIT Campus ONLINE cites an anthropologist Robert J. Priest:
Für Akademiker ist es ganz einfach, sich zu diskreditieren. Sie müssen nur sagen, dass sie religiös sind
For academics it's easy to discredit oneself. You just have to say you are religious.
(Source; translation by myself, I could not find the original citation)
I searched for surveys about that claim but could not find much, except creationists arguing against evolution theory.
So my question:
Are there surveys about discrimination of theist people by atheists in academia?
EDIT
I deletet the follow-up question "Is there discrimination against theists by atheists in academia?" because it is too opinion based and is probably answered within the survey(s) I am searching for.
