Despite increasing secularism around the globe, belief in ghosts and other paranormal phenomenon remains prominent in many cultures. 42% of Americans believe in ghosts, and 52% in the United Kingdom. Many more believe in ghosts in other parts of the world, particularly in Asia, where ancient cultures still thrive – superstitions and all. Regardless of whether or not ghosts are real, belief in the paranormal has important societal functions. Belief in the paranormal helps humans assign order to an increasingly chaotic world, create social bonds, and even boost physical and mental function (another reason to keep knocking on wood.) Although belief in the paranormal can seem like a harmless pastime, is there a downside to having superstitions?
