Psychologists and researchers who studied Pearl Curran's automatic writings in the 1930s came to the conclusion Patience Worth was a fictitious creation of Curran.[155][156] In 1931 George Valiantine was exposed as a fraud in the séance room as it was discovered that he produced fraudulent "spirit" fingerprints in wax. The "spirit" thumbprint that Valiantine claimed belonged to Arthur Conan Doyle was revealed to be the print of his big toe on his right foot. It was also revealed that Valiantine made some of the prints with his elbow.[157]

Just as in any profession, mediums have specialties and areas of expertise. Unlike Allison Dubois in Medium, I don't work with the police in solving crimes. Or, unlike Melinda Gordon in The Ghost Whisperer, I don't help tormented souls cross over. Over the years, it has become very clear that my job lies in working with souls who have happily crossed over to the other side and, for the most part, are at peace. Sure, they may have regrets or unresolved issues, but they're not haunted or lost. Oftentimes, it's the living that are not at peace. The main goal of your deceased loved ones and spirit guides is to assist you in moving on, free of grief and struggle, so you can fulfill your life lessons and enjoy your time here on earth.

The article about this phenomenon in Encyclopædia Britannica places emphasis that "… one by one spiritual mediums were convicted of fraud, sometimes using the tricks borrowed from scenic "magicians" to convince their paranormal abilities". In the article it is also noted that "… the opening of the wide ranging fraud happening on spiritualistic sessions caused serious damage to reputation of the movement of a Spiritualism and in the USA pushed it on the public periphery".[208]
In the late 1920s and early 1930s there were around one quarter of a million practising Spiritualists and some two thousand Spiritualist societies in the UK in addition to flourishing microcultures of platform mediumship and 'home circles'.[18] Spiritualism continues to be practised, primarily through various denominational Spiritualist churches in the United States, Canada, Australia and the United Kingdom. In the United Kingdom, over 340 Spiritualist churches and centres open their doors to the public and free demonstrations of mediumship are regularly performed.[19]
