From the Daily Wail:
'It is not true to say anyone can have their brain hacked,’ said qualified therapist Mark Powlett. ‘You absolutely can’t make people do things they don’t want to do.
‘People who are under hypnosis are put in a very relaxed state which makes them open to positive suggestion. But the last thing a show like this wants is people who are relaxed – as they wouldn’t be able to perform as required.’
Mr Powlett said contestants on the show, hosted by Phillip Schofield, were not under Barry’s ‘control’, but playing along willingly.
‘The people on stage want to entertain, they what to be in front of people and they want to win money,’ he said.
