I thought the most truthful answer for me would be "Rarely", given all possible interpretations of the question. I think that it should have been qualified "within the past year", to eliminate the follies of truth-seeking in one's youth. Someone who answers "Never" cannot be considering when they were a five-year-old. I have believed or wanted to believe a lot of crazy things. Even right now, thinking as an atheist, I rarely have those moods, and only rarely due to my recognized (and combated) tendency toward magical thinking. However, right now, thinking as a Christian, I would have doubts constantly, because no matter how much I would like to believe, it is plain to see that most of what I am expected to have faith in as a Christian is complete crap. I am capable of adopting either mode of thinking, as is anyone else here. We're just better at one mode than others.
