Personally, I think that psychic readings done over the phone are a lot less likely to be influenced by all sorts of information that you can’t help giving away in a face to face reading.  Before you’ve even said a word, whether they mean to or not, a psychic reader can read all sorts of things into your clothes and the way you carry yourself if you’re in front of them. 

Psychic Four was very motherly, constantly calling me "darling" and telling me how sorry she was for my loss. Her method of Emily-contact was a mix of prayer and coffee-dregs reading. She made me a small cup of Turkish coffee and when I finished the liquid, she placed the saucer on top of the cup, had me hold it with both hands while moving my arms in a circle three times and then flip the cup and saucer over and put it on the table. She put a blue glass cube with white circles on all six sides on top of the overturned cup and had me to put my finger on the cube and make a wish. I did, and she asked me for the photo. I handed her my phone. She put a small statue of a Turkish philosopher and an angel snow globe in front of me and told me to hold on to both and praying while she turned on her laptop and started playing weird reverb-heavy New Age music featuring a man and woman speaking about being intoxicated on love (not Beyonce style, unfortunately). She was going to ask Emily to make herself known to me.
In 1880 the American stage mentalist Washington Irving Bishop published a book revealing how mediums would use secret codes as the trick for their clairvoyant readings.[84] The Seybert Commission was a group of faculty at the University of Pennsylvania who in 1884–1887 exposed fraudulent mediums such as Pierre L. O. A. Keeler and Henry Slade.[85] The Fox sisters confessed to fraud in 1888. Margaret Fox revealed that she and her sister had produced the "spirit" rappings by cracking their toe joints.[86]
