O teste usou ressonância magnética para analisar o desempenho cerebral de dois grupos de pessoas, 20 evangélicos pentecostais e 20 céticos. Eles ouviram várias orações pré gravadas e foram informados que 6 delas foram feitas por céticos, 6 por pessoas religiosas e 6 por pastores que curam. O detalhe é que todas as orações foram feitas por pessoas religiosas comuns.
No grupo dos céticos, não houve diferença nenhuma. Estes simplesmente ignoraram as orações. Mas no grupo dos crentes houve um efeito interessante. Para cada oração que eles achavam que era feita por um religioso, determinadas áreas do cérebro relacionadas ao ceticismo e à tomada de decisões tinham suas atividades reduzidas, fazendo com que as cobaias entrassem em um estado quase de transe. O efeito era mais forte nos casos em que se pensava que a oração era realizada por um religioso dito com poder de cura.
O orador não precisava nem ser carismático (lembre-se que todos eram simples cristãos e que, para efeito de pesquisa, eles trocavam as mensagens). Bastava o crente ser avisado que ele estava escutando um pastor que cura para sofrer o efeito.
O estudo não mostra exatamente onde está a relação casual, se por exemplo os crentes acreditam nos pastores super poderosos por acharem que eles falam mais a verdade do que os outros. De repente tal efeito pode se aplicar em outras relações humanas, como aquelas com doutores, advogados, mecânicos de automóveis e técnicos de informática.
No entanto, o estudo me parece explicar como um pastor quase sem carisma (e um tanto feio) como o Apóstolo Valdemiro Santiago consegue tantos seguidores. Na verdade, explica como qualquer igreja, mesmo as de fundo de quintal, parece prosperar. Ser pastor é mais fácil do que parece."

Whatever else you think about charismatic preachers, they have a dramatic power over their audience. While their followers believe them to have special powers, a new brain imaging study by Uffe Schjødt at Aarhus University in Denmark suggests that it's all just a product of their imagination.
In fact, the brain imaging study is only part of the story. What's even more remarkable is what it says about how some people come to fall under the spell of these charismatics.
What they did was to take a small group of pentecostal Christians and a matched group of non-believers. Both were chosen so as to represent the extreme ends of the belief scale.
They were asked to listen to prayers being read by three different people who, they were told, were a non-Christian, an ordinary Christian, and a Christian 'known for his healing powers'. In fact, they were all ordinary Christians...
So there was no real difference between the prayers (the speakers were mixed up to make sure differences in speaking style could not affect the experiment). The only difference was what the listener was told, but what a dramatic effect it had!
When asked, the pentecostalists rated the one they were told was a healer as the most charismatic, and the person they thought was non-religious as much less charismatic (see the graph). For the non-believers, there was a slight trend in the same direction, but it was small and insignificant. Basically, they weren't taken in by the deception.
But the pentecostalists were. Just telling a pentecostalists that someone has healing powers makes them think that they are highly charismatic. What's more, they didn't feel God's presence in the prayers read by the person they were told was a non-Christian.
So where does the hypnotism come in? Well, specific regions of the pentecostalist's brains became somewhat activated when listening to the prayer from the 'non-believer', but highly deactivated when listening to the prayer from the 'charismatic healer'. The prayer from the ordinary Christian resulted in deactivation too, but on a small scale.
And the regions that were deactivated by the 'charismatic healer' were all associated with 'executive function' - the part of the mind that evaluates, monitors, and makes decisions. A similar response has been seen in the brains of people undergoing hypnosis - as well as meditation.
In other words, they went into a bit of a trance.
What Schjødt thinks is happening here is that, when we listen someone we trust implicitly, we switch off our critical faculties, and just let what they are saying wash over us. In the words of the researchers, "subjects suspend or 'hand over' their critical faculty to the trusted person."
Now, in this scenario the atheists were immune to the powers of the charismatic preacher. But we shouldn't run away with the idea that this is a particular characteristic of religious people. Stage hypnosis shows that you that you can see similar effects in secular situations - and Milgram's scary experiments in authority also spring to mind.
What strikes me most about this study is that the charisma of the preacher was all in the minds of the subjects. They were willing dupes.
And what this study also shows is just how closely linked the razmatazz of charismatic preachers is to the showmanship of stage hypnotists. They seem to be exploiting a common human weakness - and one that has enormous power!
