Every child is told to take a test to see if they are crazy or not. The tests are guarenteed 100% accuracy. Only 5% of the population is ever proven crazy with these tests, the other 95% are given normal lifes. The labeled "Insane" are sentenced a life imprisoned inside an asylum with no one doubting their lack of sanity. Same goes for Dipper's family when the machine sentences him to the asylum where he is poked and proded with needles, given meds he never needed in the first place. Hoping everyday that he will have the chance to get out and take back the normal life he is owed.
