One result of the initial articles in Campbell's magazine was that two other researchers, William O. Davis and G. Harry Stine, visited Dean and witnessed a demonstration. Results of this visit were published in the May 1962 and June 1976 issues of the magazine, the name of which had been changed by Campbell from "Astounding" to "Analog". Davis witnessed a demonstration by Dean, and wrote: "It was the conclusion of both Harry Stine and myself that we had witnessed a real anomaly and that the possibility of fraud in the demonstration was slim." Aerospace researcher Jerry Pournelle — who, like Stine, was also a science fiction writer — pointed out that Stine was well qualified to make a judgment on the device, but that he was more gullible than other persons.
