A large part of internal conflict is due to information entering one's mind that exceeds one's capacity to handle

For example, when I swim, water will definitely get into my nose, and I know there is a possibility of contracting a brain-eating amoeba, which might make me worry and feel conflicted, even though the probability is as low as several hundred million to one

While playing at the beach, if I get cut by an oyster shell, I could also contract Vibrio vulnificus and might face amputation or death

The human brain cannot process information about probabilities, which leads to conflict; it's better not to know.
