Does Alcohol Reveal the Real You?

Alcohol is only a truth serum for a brain that’s not working well, not your everyday brain.

“Here’s to alcohol: the cause of, and solution to, all of life’s problems.” So sayeth noted philosopher Homer Simpson. It’s the ubiquitous social lubricant that makes it easier to socialize, and some would say, freely speak our minds and reveal our true feelings to others.

But is alcohol really a truth serum? The short answer is yes, but only for the kind of truth that leaks out of a brain that’s not working too well. Which is to say, no, not really.

So what is going on when we tell someone we barely know how wonderful, no, I mean really great, they are when we’re smashed?

Alcohol, the Depressive Stimulant. Of Course You’re Confused.

As a depressant, alcohol reduces some neurotransmitters and increases others. 

  • Alcohol reduces production of excitory neurotransmitters like glutamate that support clear thinking and produce energy.
  • Alcohol increases production of inhibitory neurotransmitters such as gamma-Aminobutyric acid, or “GABA,” which slows. Everything. Down.
  • Alcohol’s effect on your cerebral cortex is what makes your brain so, er, different when you’re drinking. This is where booze knocks clear thought off the rails, making you less careful about what you say and making Drunk You a stupid, brakes-off version of Real You.

    Alcohol also makes you process sensory information less efficiently, cutting down your reaction time

    A cerebellum on alcohol is out of whack, making the inebriated stumble, lose balance, and fall down, or maybe all of the above at once.

    While it’s busy gumming up the works on one hand, alcohol also increases the amount of pleasure-inducing dopamine your brain releases. This is why alcohol makes you feel happy, even as it’s making your brain work less well.

    Dopamine’s also the reason alcohol can seem to offer a respite from life’s problems.

    Of course, alcoholic logorrhea creates others. Hey, there are apps to help you avoid drunk dialing.

    There are people who wonder why their loved ones only open up when they’re drunk. Is it the booze talking, or are these honest expressions of affection? It’s likely a question of drunkenness. If someone’s only slightly inebriated, such statements are more likely to be true because the the brain’s mostly still working. But while alcohol doesn’t make the brain function in a completely new way — which is to say you’re still in there somewhere — it does make clear thinking less likely, so the feelings being so freely expressed are the result of impaired thinking. They’re likely to align with the sober truth sometimes: Even a broken clock is right twice a day.
