Although the Dunning–Kruger effect was formulated in 1999, Dunning and Kruger have noted similar observations by philosophers and scientists, including Confucius (“Real knowledge is to know the extent of one’s ignorance”), Socrates (“I know that I know nothing”), Bertrand Russell (“One of the painful things about our time is that those who feel certainty are stupid, and those with any imagination and understanding are filled with doubt and indecision”), and Charles Darwin, whom they quoted in their original paper (“Ignorance more frequently begets confidence than does knowledge”).
(What they were talking about is that an unskilled person will overestimate his ability, being ignorant of what real ability is or looks like, while the skilled person, perceiving the task to be easy, will underestimate his relative standing.)
So, how can we ever know that our believing in God, accepting the truth of His existence, is correct, given that maybe our confidence is the result of ignorance?
And does this seem like it could be related to the falling-away of so many people when they go to college?
