Speaking of readings, the first thing to know is that there actually are two different types of Tarot readings: question readings and open readings. In question readings, you are addressing a specific question. Tarot is not intended to answer specific yes or no questions. Most say it also shouldn't be used to make decisions, but instead should be used as a guide to help you make the decision yourself. For this reason, the way a question is stated is very important. Tarot reader and teacher Joan Bunning gives this advice:
In March 1902 in Berlin, police officers interrupted a séance of the German apport medium Frau Anna Rothe. Her hands were grabbed and she was wrestled to the ground. A female police assistant physically examined Rothe and discovered 157 flowers as well as oranges and lemons hidden in her petticoat. She was arrested and charged with fraud. Another apport medium Hilda Lewis known as the "flower medium" confessed to fraud.
The exposures of fraudulent activity led to a rapid decline in ectoplasm and materialization séances. Investigator Joe Nickell has written that modern self-proclaimed mediums like John Edward, Sylvia Browne, Rosemary Altea and James Van Praagh are avoiding the Victorian tradition of dark rooms, spirit handwriting and flying tambourines as these methods risk exposure. They instead use "mental mediumship" tactics like cold reading or gleaning information from sitters before hand (hot reading). Group readings also improve hits by making general statements with conviction, which will fit at least one person in the audience. Shows are carefully edited before airing to show only what appears to be hits and removing anything that does not reflect well on the medium.
