I hate the phrase because it presumes that the person one becomes for less than 1% of their conscious life, while under the effects of a mood-altering drug, is a greater representative of their true self than their behaviour of the other 99%+ of their life while they are sober and clear of head.

The problem here is that there are a bunch of other situations in life for which being inebriated is a reasonable proxy. Sleep deprivation, extreme stress, social isolation, etc.

New parents often suffer from all of these! If you are a shithead when drunk, are you also going to be a shithead to your wife and newborn child when they most need you to be level-headed and calm?

Similarly for any sort of dangerous job. If I'm going to be sailing offshore for weeks alone with someone, you can be damn sure I'm testing ahead of time how they handle stress.
