In the best case, this allows for social vulnerability that leads to trust and trust is the basis for society.
Note that for some people, they are deep into traumatic fear stress that inebriation might actually make unmasking look like a fight, flight, fawn…
Just a counterthought:
If I your anxiety stress becomes reduced, you might be less anxious to call your boss an idiot. :-D
Seriously: if you become less afraid of the social consequences, this actually might increase your ego. I know quite some people who in my observation have a stronger ego under influence than when they are sober.
As a “boss” I actually like when people challenge me, including calling me an “idiot.” I’ve gone as far to tell people to feel free to tell me to, “fuck off” if I’m getting something wrong. It’s all about intent and trust. If we can’t be honest things don’t work.
Your boss may in fact be an asshole and unmasking would make you feel more incautious about being yourself, which might mean a narcissistic outburst from all your pent up frustration.
Terribly unhealthy but it supposedly accomplished it's purpose
Other communities strive to make communication safer and full of good examples which helps get over excessive shyness. Always seemed a better direction to me.
Yes fully open, healthy attachment recognizing, empathy filled communities, are leaps and bounds healthier than ones with pathologically traumatized people coping with that with medication/intoxication.
