Superstitions are prevalent throughout India and vary widely between regions. They stem from a lack of education and provide a sense of control, but can also harm individuals and society. Some common Indian superstitions include not cutting nails at night, believing that crow excrement brings good luck, and hanging lemons and chilies to ward off evil. Widespread superstitions are fueled by mass illiteracy and a desire to manage unknowns, but ultimately undermine productivity and rational thinking.
