Scientologists 'flat earthers' - 2007-07-10
Mr Brooks went on to argue that modern psychiatry used many methods that were largely "unproven" and psychiatric assumptions - such as chemical imbalances in the brain - simply did not exist.
Almost immediately after Mr Brooks finished his interview, Sydney University psychiatrist Chris Tennant phoned ABC Radio to reject the Scientologist's beliefs.
Saying it was "so sad to hear the flat-earthers getting on the radio", Professor Tennant denied modern psychiatry was largely "unproven", stating the amount of research on mental illness was "as strong" as that for cancer and heart disease.
"It's a tragedy to hear this mumbo jumbo being proselytised by this group," he said.
"The sad thing about this sounds to be that this girl may well have been prescribed some psychiatric treatment but living in a family which had the Scientology attitude there is no way there would have been what we term compliance."
