We've all heard stories about people acting drunk after unknowingly being served non-alcoholic beer, but could this placebo effect potentially impair one's ability to operate a vehicle?

Neuropsychology researcher here. Some research has shown that expectancy/placebo effects of alcohol can affect more than social inhibition of behavior.



For example, Assefi and Gary 2003 showed placebo-induced impairments on eyewitness memory/response to misinformation. 



Much more relevant to operating a motor vehicle is Gilbertson et al. 2010. Participants who believed they had received alcohol performed worse on measures of covert attention. The findings suggest that this effect may be mediated by one's previous experience with alcohol, but that conclusion is not fully substantiated and requires more research.
