Pareidolia — A vague and random stimulus (often an image or sound) is perceived as significant, e.g., seeing images of animals or faces in clouds, the man in the moon, and hearing non-existent hidden messageson records played in reverse.

Often we are faced with situations where our intuition misguides us. Cognitive biases are systematic patterns of deviation from norm or rationality in judgment. Many of these biases affect belief formation, business and economic decisions, and human behavior in general.
