In one experiment, those who consumed alcohol (rather than a placebo beverage) were doubly likely to be caught mind wandering during a reading task, yet were less likely to notice that they zoned out (Sayette et al., 2009). Alcohol not only reduces self-awareness, it also produces a sort of “myopia” by focusing attention on an arousing situation (say, provocation) and distracting it
from normal inhibitions and future consequences
