The late (1946-2003) Hunsberger (Wilfred Laurier U.) and fellow psychologist Altemeyer (U. of Manitoba) have surveyed mostly active atheists in North America--ones who have joined clubs or spoken publicly about atheism--and present their findings. They discuss such matters as whether people become atheists because they are bitten by another atheist, religious ethnocentrism, ordinary American atheists, and agnostics and inactive believers in the Manitoba parent group.
