NEW YORK (Reuters Health) - How long a man's second finger is relative to his fourth finger appears to predict whether he is prone to be physically aggressive toward others, according to a new study by researchers at the University of Alberta, Edmonton, Canada.
But it's not finger length that causes aggression, study author Allison A. Bailey warned in an interview.
She explained that the important factor is the male hormone testosterone. Fetuses are exposed to various levels of this hormone in the womb, and research shows that men who were exposed to higher levels tend to have shorter second fingers, relative to their fourth fingers. "More testosterone, relatively longer ring finger," co-author Dr. Peter L. Hurd told Reuters Health.
Men with shorter second fingers were probably exposed to more testosterone in the womb, and this may cause them to be more prone to physical aggression later in life, Bailey explained. "More testosterone in the womb predicts more physical aggression in men," she told Reuters Health.
Alternatively, both testosterone exposure and finger length may be influenced by a "deeper third variable," Hurd noted. Regardless, the study shows that "events in the womb can have subtle effects on children's personality," Hurd added.
This is not the first study to link the ratio between a man's second and fourth fingers to his personality, Bailey noted. Previous reports have found that men with smaller ratios - meaning, their second finger is much smaller than their fourth - tend to do better in sports, and are perceived as more dominant and masculine by women.
However, other research has shown that men with smaller second-to-fourth finger ratios are at higher risk of autism and immune deficiency.
To investigate how finger ratios match up with physical aggression, Bailey and Hurd measured the finger ratios in 298 psychology students, and asked them to complete a questionnaire measuring aggression.
The questionnaire measured four types of aggression, Bailey noted: physical ("if someone hits me, I hit back"), anger ("I flare up quickly"), hostility ("I am often eaten up by jealousy"), and verbal ("I tell my friends when I disagree with them").
The researchers found that shorter second-to-fourth finger ratios predicted proneness to physical aggression, but not other types of aggression, and only in men, not in women.
In general, men had smaller finger ratios than women, the authors report in the journal Biological Psychology.
Bailey cautioned that these findings only link a shorter finger ratio to a tendency toward physical aggression, and do not show that men with shorter ratios are actually more aggressive. "Somebody might never have acted on anything," she said.
Moreover, behavior is influenced by many other factors, Bailey added. Finger ratios are "just one piece of the puzzle," she said.

You bet.
Junk survey. Junk science ====> Attack on males. Approved by the MSM and NOW.
On the money, Laz...
Just don't pull it, please.
Jeez... and I was just starting to catch on to the size of the feet thing.
Not so sure it's an attack on males. I think there have been many scientific studies correlating testosterone and aggression. If you look at the side effects of male hormone-like drugs you will see "aggression" as one.
So if you 'hit back' or 'disagree' with friends, you're too agressive!
("if someone hits me, I hit back"),("I tell my friends when I disagree with them").
So, basically, the article is stating that men with shorter second fingers are pansies!
You say if I give you the finger I'll get more testosterone?
Consider it done.
I think the second finger is ring finger and 4th is index ("Mr. Pointer").
Haven't you heard...size doesn't matter...:^)
They are speaking of the index finger and the ring finger (the index being shorter indicates more agression).
Deep in the article they say the ring finger is the fourth. Therefore I guess they mean the index finger is the second.
That's for musicians; the psychologists, it appears, do it differently. See #16.
Paging Lurking2Long ... paging Lurking2Long ... Report to the bridge sales office. ;)
Second finger is your index finger (next to thumb) and 4th is ring finger. My 2nd is much smaller than the 4th and I have aggression problems, at times.
How is the author numbering the fingers? I thought "the second finger" she was talking about was the middle one, until she started saying the fourth one is the ring finger. In which case, her "second finger" would ordinarily be called the index finger. In which case she considers the thumb a finger.
How tough would it be to describe her finger assignment before launching into the rest of the story?
