Finger length may predict financial success

An interesting article. Could there be some truth to the study of Palmistry?

By RANDOLPH E. SCHMID,AP Science Writer AP - Tuesday, January 13
WASHINGTON - The length of a man's ring finger may predict his success as a financial trader. Researchers at the University of Cambridge in England report that men with longer ring fingers, compared to their index fingers, tended to be more successful in the frantic high-frequency trading in the London financial district.
Indeed, the impact of biology on success was about equal to years of experience at the job, the team led by physiologist John M. Coates reports in Monday's edition of Proceedings of the National Academy of Sciences.
The same ring-to-index finger ratio has previously been associated with success in competitive sports such as soccer and basketball, the researchers noted.
The length ratio between those two fingers is determined during the development of the fetus and the relatively longer ring finger indicates greater exposure to the male hormone androgen, the researchers noted.
Previous studies have found that such exposure can lead to increased confidence, risk preferences, search persistence, heightened vigilance and quickened reaction times.
In a separate study last year, Coates and colleagues reported that the hormone that drives male aggression and sexual interest also seemed able to boost short term success at finance.
They studied male financial traders in London, taking saliva samples in the morning and evening. They found that those with higher levels of testosterone in the morning were more likely to make an unusually big profit that day. Testosterone, best known as the male sex hormone, affects aggression, confidence and risk-taking.
In the new study, the researchers measured the right hands of 44 male stock traders who were engaged in a type of trade that involved rapid decision-making and quick physical reactions.
Over 20 months those with longer ring fingers compared to their index fingers made 11 times more money than those with the shortest ring fingers. Over the same time the most experienced traders made about 9 times more than the least experienced ones.
Looking only at experienced traders, the long-ring-finger folks earned 5 times more than those with short ring fingers.
While the finger ratio, showing fetal exposure to male hormones, appears to signal likely success in high-actively trading that calls for risk-taking and quick reactions, it may not indicate people who would do well at other sorts of financial activities, the researchers said.
Some traders require additional skills on dealing with clients and sales workers.
And the advantage may even reverse for some, Coates team said, such as traders taking a more analytical and long-term approach to the markets.
One study, which looked at average finger ratios in university departments found that faculty from math, science and engineering exhibited longer index finger ratio, rather than ring finger, they noted.

Cows Have Strange Sixth Sense

A study of Google Earth satellite images has revealed that herds of cattle tend to face in the north-south direction of Earth's magnetic lines.

Staring at cows may not equal the thrill of spotting celebrities in public or rubbernecking at car accidents, but the researchers found nonetheless that our bovine friends display this strange sixth sense for direction.
Their field observations of red and roe deer also showed those animals facing toward magnetic north or south.

"Google Earth is perfect for this kind of research, because the animals are undisturbed by the observer," said Sabine Begall, a zoologist at the University of Duisburg-Essen in Germany and coauthor on the study detailed in the journal Proceedings of the National Academy of Sciences.

Wind and time of day did not offer better explanations for why 8,510 cattle in 308 locations around the world would mostly face north-south. Shadows suggested that many of the images were taken on cloudless, sunny days, so Begall's group also factored in direct ground observations of cattle herds.

A strong wind or sunlight on a cold day have typically proved more the "exceptions to the rule" that might cause large animals to face away from magnetic north-south.
The data on 2,974 deer came from direct ground observations and photos in the Czech Republic. Researchers also examined fresh beds left by resting deer in the snow, where the animals had sought shelter deep in the forest away from the wind.
Both cattle and deer faced a more magnetic north-south direction rather than geographic north-south, (Earth's magnetic poles do not line up perfectly with the North and South Poles).

Previous research has shown that animals such as birds, turtles and salmon migrate using a sense of magnetic direction, and small mammals such as rodents and one bat species also have a magnetic compass.
Begall and fellow researchers became interested in seeing if larger mammals possessed a similar magnetic sense, following up on coauthor Hynek Burda's work on African mole-rats.

"Our first idea was to study sleeping directions of humans (e.g. when doing camping), but there are too many constraints," Begall told LiveScience. "So, the idea arose to look for other large mammals like cattle, and Hynek was fascinated when he recognized that cattle could be found on Google Earth satellite images."
Google Earth's convenience also came with some downsides. The researchers had to estimate the date, time of day, temperature and wind direction, and could not distinguish between head and rear for many of the cows because of low image resolutions.

However, the researchers suggest that the finding of large animals' sense of magnetic direction could raise other agricultural questions, such as whether keeping cows in barns facing east-west might affect milk production.
