Conspiracy theorists tend to be secretive, paranoid and distrustful of recognised authorities, so if a scientist were to say to one, ‘Would you like to come to our secure facility and let us experiment on you? It may involve being confined in a metal tube so we can scan your brain’, the answer is unlikely to be yes. So all that’s included in this section is a reasonable set of theories and assumptions based on the data we currently have available. But then, I would say that, wouldn’t I?
