The happy drunk, the sloppy drunk, the what-in-God's-name-is-going-on-with-you drunk… it's safe to say we're all guilty of acting a little differently when we're under the influence.

Next time you're down the pub, you can conduct a little social experiment,as per the research carried out by scientists at a US university. Keen to discover exactly how our personalities change after a few too many G&Ts, researchers at the University of Missouri-Columbia have categorised drinkers into four distinct categories.

Just like deciding if you're a Carrie or a Samantha, you can now figure out if you're a 'Hemingway' (good) or a 'Hyde' (not so good). The findings were based mainly on how participants' levels of "conscientiousness" (being reliable, organised and prompt) and "intellect" (understanding, being imaginative, knowing what was going on) changed as they got drunk.

Here are the findings – we'll be printing these out for our next cocktail night…

Hemingway a.k.a The "Are you even drunk?" drinker
The 'Hemingways' of this world can hold their drink well and change only slightly when under the influence. The name was inspired by Ernest Hemingway who said he could "drink hells any amount of whiskey without getting drunk."

Mary Poppins a.k.a The "I'm gonna go tell that guy he's GORGEOUS" drinker
Researchers said that this group remained sociable, agreeable and fairly together after a few drinks, though they did display higher levels of confidence, as well as getting louder. We all know a few Marys.

Nutty Professor a.k.a The "I AM BEYONCÉ" drinker
Nutty Professors became far more sociable and confident when drinking that they were in everyday life. To summarise, they're the most likely to be found on the dancefloor surrounded by the gang of new friends they just made while ordering Jagerbombs at the bar.

Hyde a.k.a The "Know the one that's one too many" drinker
The fact that this group were named for Dr Jekyll and Mr. Hyde should give you an idea of the kind of drinkers we're talking about. Hydes become more disagreeable when they drink and also display lower levels of conscientiousness and intellect. They are the most likely to "incur harm" from their drinking due to hostile behaviour, blackouts or even being arrested.
