Whats a great way to deal with superstition?

To challenge it: Through cognitive behavioral therapy. Understanding the basis for old superstitions can also be quite helpful.

Query: Superstition?: Do you mean your OWN superstitions or other people's? Magical thinking is a disorder in psychiatry but is the basis of religion, so there you go. Modern brain research suggests that magical thinking is a human "cognitive default;" we're (unfortunately) programmed that way. ("Teleological thinking") We instinctively connect things even when there's no evidence for it, in fact especially when none.

CBT: Seek a cognitive-behavioral therapist who specializes in phobias. One method they use is systematic desensitization which slowly and incrementally brings the person closer and closer to the thing they are afraid of in slow, graduated steps that help make the anxiety more tolerable.
