Confirmation bias the tendency to interpret new evidence as confirmation of one's existing beliefs or theories.
I had no confirmation bias when I first researched the Baha'i Faith, since there were no pre-existing beliefs to confirm, since I was not raised in any religion.
I only became convinced that my belief was true after I researched it.
Not raised in a religion, but some sort of
theist? As an atheist I don’t go looking for
a religion to research and adopt any more
than I study flying saucers hoping for abduction.
It may be that while not being biased for
that particular belief you were, for belief
in some religion.
Too, if it “clicked” it would be for pre existing
reasons, much as it is when one meets
a person with whom you “click”.
Your last line sounds like classic confirmation
bias. Maybe you don’t mean it the way it
came out?
