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.

I give this story the finger.
SMACKS YOU OVER THE HEAD WITH A ROLLED UP NEWSPAPER
Okay, are you supposed to look at your hand palm up or down, to count the fingers?
He hates cans!
I strongly suspect the opposable thumb set them up.
I'd say, if he gives you the finger, he's probably mad.

The comparison is between the forefinger and the ring finger.
Wait. I'm developing the appropriate response to the ALREADY POSTED NOT THIS KIND OR THAT KIND OF NEWS thread nazis.
ARRRRRRRGHHHHHHHH. -- Howard Dean
I thought that was BillyJeff's hand gestures during the announcement that he looked and looked but couldn't give a middle-class tax cut in 1993-94. Instead (starts this gesture) we're raising gas taxes and other "revenue enhancements" so we can get through this fiscal hole.

Please don't be pissed. Please SEARCH before posting, and consider what is truly a "Breaking News" item, and what is not. Read guidelines for posting...no biggie.
I'm taking a shower.
-Perhaps we should do the measurement of all newborn males. That way we can identify potential aggressors, label them as such, and chronically medicate them so as to initiate a new more feminine non-aggressive brave new world.-
No need for sarcasm labeling. This is the scary truth.
How can you be certain? They keep making reference to the second and fourth fingers. The forefinger by definition is the first finger.
The nut who carried out the study based it on tests of psychology students. This is an aberrant, crazy section of the general population.
It's a stupid article anyways about a stupid study probably funded by my money approved by stupid bureaucrats.
