I have a study i want to share with you:
Start of study: August 30th 2010
Theory: Fat delusional people will stay fat and delusional, no matter what you tell them.
Method: Qualifying. Test subject is male, 30ish, obese and suffers from the typical delusions obese people suffer from, i.e. a misunderstanding of their own and other people's body weight, looks and overall idea of health. In the study, several scientists will approach the subject and try by different means to make him see his own errors and lead a healthier, more athletic life. These means are reason, insults, experience, historical examples and so on. If the test subject fails to realize his own delusion and fatness, the theory is proven.
Result: Theory proven.
