Open readings address the larger aspects of your life rather than a specific problem area or question. They're usually done when you're entering a new phase of life, such as getting married, graduating from college or starting a family. You can somewhat direct the reading if you have a general area you want to cover, such as your career or health, but that's as specific as the direction gets.
Skeptics have challenged the veracity of the claims of psychic readings, largely through disclosure of the methods. Psychologist Richard Wiseman's 2011 book Paranormality: Why We See What Isn't There noted the tricks of the trade, and Wiseman noted in a podcast appearance that the disclosure generated negative feedback from the psychic community.
The psychical researcher Hereward Carrington exposed fraudulent mediums' tricks, such as those used in slate-writing, table-turning, trumpet mediumship, materializations, sealed-letter reading, and spirit photography. The skeptic Joseph McCabe, in his book Is Spiritualism Based on Fraud? (1920), documented many fraudulent mediums and their tricks.
Every month I give Intuition Circles which are an excellent chance for you to meet like minded souls and learn to open your intuitive abilities in a safe environment. We meditate, share, and do exercises to show you just how intuitive you already are. Many people become friends out of these circles and it is my intention to create a community of intuitives !
