One doesn’t cause the other, but there seems to be an association for some people.

Anew study has pointed to a strange correlation with a person’s drinking habits: the ratio of their fourth digit (sometimes called the ring finger) to the second digit. Specifically, scientists found a relationship between having a ring finger that is longer than the second digit and high alcohol consumption.
The ratio of our finger lengths is something that’s set before birth, in part influenced by the hormones we are exposed to in the womb. People exposed to more estrogen tend to have second digits longer than their ring fingers, while those exposed to more testosterone can have ring fingers longer than their second digits. There are also people whose ring finger and second digits are the same length.
This latest study looked at 258 student participants – 169 of them female – to see what their finger ratios were and how much alcohol they consumed. The results showed there was a correlation between higher alcohol consumption and longer ring fingers relative to second digits, pointing towards the potential influence of hormones as a contributor to the likelihood of imbibing as a student.
“A pattern like this suggests an involvement of sex hormones, such as testosterone and oestrogen,” said Professor John Manning, of Swansea University’s Applied Sports, Technology, Exercise and Medicine (A-STEM) research team in a statement. “Digit ratio (2D:4D: the relative lengths of the 2nd [index] and 4th [ring] fingers) is thought to be an index of early testosterone (long 4th digit) and oestrogen (long 2nd digit).”
“It is known that alcohol-dependent patients have very long 4th digits relative to their 2nd digits, suggesting high testosterone relative to oestrogen exposure before birth. As expected, the associations were stronger for men than women.”
It’s worth pointing out that the association can’t establish cause and effect, so having a certain finger ratio doesn’t dictate a person’s outcome – but it’s hoped that identifying the connection could shine a light on factors underlying alcohol use.
“Alcohol consumption is a major social and economic problem,” said Manning. “Therefore, it is important to understand why alcohol use shows considerable differences across individuals.”
The study is published in the American Journal Of Human Biology.

Uh-oh, my ring finger is almost longer than my middle. What does that mean?
LOL!
It’s also a characteristic used by old school European cycling coaches to identify promising candidates.
