1. " face as real, and to read a scrambled word as normal. In the second part of the experiment, Brugger and Mohr gave all forty subjects L-dopa, the drug used for Parkinson’s disease patients that increases the levels of dopamine in the brain. They then repeated the slide show with the scrambled or real faces and words. The boost of dopamine caused both believers and skeptics to identify scrambled faces and real and jumbled words as normal. This suggests that patternicity may be associated with high levels of dopamine in the brain. Intriguingly, the effect of L-dopa was stronger on skeptics than believers. That is, increased levels of dopamine appear to be more effective in making skeptics less skeptical than in making believers more believing.8 Why? Two possibilities come to mind: (1) perhaps the dopamine levels of believers are already higher than those of skeptics and so the latter will feel the effects of the drug more; or (2) perhaps the patternicity proclivity of believers is already so"
