"Superstition" is Stevie Wonder cataloguing the ways people talk themselves into fear. Written in 1972, the song lists superstitions one after another -- broken mirrors, ladders, bad luck, voodoo -- building a catalogue of irrational belief until the groove makes you dance right through the dread. Stevie is not mocking the superstitious. He is watching them. The song observes the rituals people invent to control what they cannot predict. The funk makes the fear bearable. The laughter keeps the darkness at arm's length.
