GREAT MOMENTS IN RESEARCH
MARC ABRAHAMS, GUARDIAN - Last week, we looked at the work of Professor
John Thomas Manning of the University of Central Lancashire, the leading
figure in finger-length ratio. Today we consider several other high
achievers. Like Manning, they specialize in comparing the length of a
person's second (index) finger with the length of their fourth (ring)
finger. They call this "the 2D:4D ratio".
Emma Nelson, a graduate student who sometimes works with Manning, has
begun a series of finger-related studies. One examines the 2D:4D ratio
of hand outlines stenciled on cave walls. Nelson hopes 2D:4D will show
whether the hands belonged to ancient men or women. Another study uses
finger-length ratio to better understand the topic Testes Size and
Dominance in a Group of Captive Chimpanzees.
Martin Voracek of the University of Vienna takes a great interest in
fingers. He collaborates with Manning, and also does research
independently.
Voracek and Manning recently reported that, by measuring a man's 2D:4D,
they could predict, to some degree, how many sexual partners he would
have. But they say this works for heterosexual men only. And, so far,
they are only confident that it applies to Austrian men. Voracek and
Manning have also published a report on the perhaps inevitable question
of whether the finger-length ratio is related to the length of the
penis. Yes, they say, it is. . .
Meanwhile, S. Marc Breedlove, a professor of neuroscience at Michigan
State University, has become a giant of finger research. In 2000, his
study, Finger-length Ratios and Sexual Orientation, appeared in the
journal Nature. It features a handy graph. The reader can see that, on
average, gay and straight women have distinctly different finger ratios
- and gay and straight men have differing ratios, too. These
distinctions, curiously, are true of the right hand or of the left, but
not of both.
