Robinson had a penchant for mink coats and other trappings of wealth, and was accused of taking financial advantage of his followers. Mitch Horowitz devotes a chapter to Robinson in his 2009 book "Occult America", writing that by all accounts Robinson was sincere in his devotion to Psychiana and truly believed he was offering useful guidance and advice. Additionally, writes Horowitz, Psychiana was wildly successful, but much of the movement's income went to cover postage costs for mailing thousands of Psychiana pamphlets. Robinson's annual income was estimated at the equivalent of about $130,000 in 2009 dollars—above the average income, but not outrageously so and within the reach of many white collar workers and hardly rising to the level of an opulent lifestyle.
