(note: It is widely believed that the creation of Scientology was the result of a bar bet between L. Ron Hubbard and Robert A. Heinlein. According to Scientology critic Lindsay[Lindsay] this is “definitely not true”, no such bet was ever made, it would have been “uncharacteristic of Heinlein” to make such a bet, and “there’s no supporting evidence” unless you consider several of Heinlein’s autobiographical pieces and biographical pieces written by his wife, which makes this claim repeatedly.)
