Beware the Cold Read
Many of you probably remember the psychic phone fad from the 90's. You could call a 900 number and get a personal read from a “professional psychic” who could answer all your questions and predict your future.
Many of the charlatans used a technique called cold reading to create a custom future using cues from your answers to questions, tension in your voice and even body language for personal visits. The key to a cold read is to provide general information that actually pertains to most people. That's why they call it cold.
