Low 2D:4D
You’ll find that low 2D:4D men are confident and assertive.
Those with lower digit ratios show
more aggressive behavior and more dominating personalities – both hallmarks of high testosterone levels.
One study [5], showed that in a group of 171 healthy men, low
2D:4D was associated with competitiveness and aggression, whereas in women there was no association found.
A 2016 study found that low digit ratio men are
faster, more athletic and have better spatial awareness [4]. They are also risk takers.
To use the evolutionary terminology again, this makes them perfect
hunter-gatherers. The most manly of jobs.
It’s not all good though. Low digit ratios may also linked to higher incidences of alcoholism and video game addictions too [6].
Those with a low 2D:4D (indicating a long ring finger relative to the index finger) have been found to have:
- Higher sperm numbers
- Higher testosterone concentrations
- Lower estrogen and prolactin levels
And men with lower androgen levels? They tend to have more equal length digits in line with females.
High 2D:4D
High ratio men on the other hand can be more superstitious and have a nice, agreeable charm to their personality. They are less threatening to females which is probably why they’re more likely to have female friends.
They are also more likely to suffer from eating disorders, and may even have more feminine handwriting.
Femininity and sexuality
Research also shows that gay men
might have a higher incidence of high 2D:4D, whereas gay women could have lower 2D:4D [7].
Currently there’s a bit of discrepancy in the research and no agreement has been made. Why? Well, there are some studies saying that there’s a link and others saying there isn’t.
