In March 2017, medium Thomas John was targeted in a sting operation and caught doing a hot reading. The sting was planned and implemented by skeptical activist Susan Gerbic and mentalist Mark Edward. The unmarried couple attended John's show using aliases, and were "read" as a married couple Susanna and Mark Wilson by John. During the entire reading, John failed to determine the actual identities of Gerbic and Edward, or that they were being deceptive during his reading. All personal information he gave them matched what was on their falsified Facebook accounts, rather than being about their actual lives, and John pretended he was getting this information from Gerbic and Edward's supposedly dead—but actually nonexistent—relatives.
Cold reading also explains why psychics have consistently failed scientific tests of their powers. By isolating them from their clients, psychics are unable to pick up information from the way those clients dress or behave. By presenting all of the volunteers involved in the test with all of the readings, they are prevented from attributing meaning to their own reading, and therefore can't identify it from readings made for others. As a result, the type of highly successful hit rate that psychics enjoy on a daily basis comes crashing down and the truth emerges – their success depends on a fascinating application of psychology and not the existence of paranormal abilities.
