Overfamiliarity with an idea can lead you to accept the information as true without questioning it. Have you ever spilled salt and then had to throw a pinch of it over your left shoulder? Are you afraid that whistling in the dark will cause bad things to happen? Have you ever wondered where superstitious behaviors originated and why they are present today? When you begin to ask why, you have started the critical-thinking process.
