What the Length of Your Fingers Say About Your Personality

Your ring-to-index finger ratio can tell a lot about what you’re good at and even what mental disorders you are prone to.

The eyes may be the window to the soul, but the hands can tell you a lot about a person too. Whether they are calloused for instance, or cotton soft. The fingers in particular can give you further insights. A collaborative study conducted by Oxford and Northumbria researchers in the UK, found that differences in the lengths of certain fingers indicated whether a person tended to be more promiscuous or monogamous by nature. The secret lies with the ring finger in comparison to the index.


After studying 585 North American and British men and women, they found that those who had longer ring than pointer fingers, in either sex, tended to be more promiscuous. While those who had a longer pointer than ring fingers tended to be more monogamous. It’s important to note that the study suggests but doesn't prove a biological basis for relationship pattern preferences.

A longer ring finger was associated with more testosterone exposure in the womb, the hormone responsible for the libido in both genders. Men and women have differing levels of each sex hormone. Levels vary greatly among both genders. Some men have high testosterone for instance, as do some women, some men low testosterone, and so on.

Longer ring fingers were associated with a tendency toward more promiscuous relationships in one study.

A McGill University study, including 155 men, found that those with shorter index fingers in comparison to the ring finger were more agreeable and treated women nicer, than those with longer index fingers and shorter ring fingers. The first case is called a small digit ratio.

This agreeability wasn’t reserved for the women they were romantically involved with either, but occurred with female family members, coworkers, and friends, as well. These men, researchers assume, may be more willing to compromise, a trait necessary to healthy relationships. Debbie Moskowitz was the lead author in this study. A professor of psychology at the university, she said that men with a larger ring finger tended to have more solid relationships and were more likely to have children, due to their agreeable nature.

Men with a longer ring than index fingers may be more likely to have children.

In this latest study, neuroscientists at The Norwegian University of Science and Technology (NTNU), found that they could predict whether a person was a good athlete or if they were more of the anxious type, by examining index to ring finger ratios. Both men and women with longer ring fingers are better at spatial tasks, researchers determined. As such, they are better at physical jobs and athletics.

There are drawbacks however to those with a longer ring finger. For instance, they are at higher risk of ADHD, Tourette’s syndrome, and autism. These conditions are more prevalent in men. There are also advantages for those with a longer pointer finger. Low testosterone exposure in utero has been linked with better verbal memory. It was also associated with a higher risk of anxiety and depression, issues typically more prevalent in women.

NTNU doctoral student Carl Pintzka completed this latest study for his dissertation. He wanted to associate in utero testosterone exposure with a higher aptitude for physical tasks. He first recruited 42 female participants and measured the length of their index and ring fingers. Next, he gave half the group a drug which would drop their testosterone levels down. The other half received a placebo. Then he gave them various exercises to perform.

 

Women in this study were asked to maneuver around a virtual maze, to see if testosterone made them better at it.

By dampening testosterone, Pintzka could evaluate whether or not the hormone affected the women’s spacial capabilities. The volunteers had to complete a virtual maze, which included mentally rotating an array of 3D objects. Pintzka said, "The women who scored best on the mental rotation tasks had high levels of testosterone both prenatally and in their adult lives, while those who scored worst had low levels in both."

Further research must be conducted to discover more about this phenomenon and how it may be applied to human health. One thing is for sure: how much testosterone we encounter in the womb and later on in life has a substantial impact on who we are. Pintzka suggests that a larger study would allow for a deeper understanding and a stronger correlation to surface. Until that time, when you take the hand of your loved one, take a look at their ring-to-index finger ratio. It may lend insight into who they really are.

FOSTA-SESTA: Have controversial sex trafficking acts done more harm than good?

The idea behind the law was simple: make it more difficult for online sex traffickers to find victims.

Has FOSTA-SESTA really lived up to it's promise of protecting sex trafficking victims - or has it made them easier to target?

Politics & Current Affairs
  • SESTA (Stop Enabling Sex Traffickers Act) and FOSTA (Allow States and Victims to Fight Online Sex Trafficking Act) started as two separate bills that were both created with a singular goal: curb online sex trafficking. They were signed into law by former President Trump in 2018.
  • The implementation of this law in America has left an international impact, as websites attempt to protect themselves from liability by closing down the sections of their sites that sex workers use to arrange safe meetings with clientele.
  • While supporters of this bill have framed FOSTA-SESTA as a vital tool that could prevent sex trafficking and allow sex trafficking survivors to sue those websites for facilitating their victimization, many other people are strictly against the bill and hope it will be reversed.
