The ‘digit ratio’ (finger length) of Barack Obama!

November 14, 2008

Left handed Barack Obama has a low ‘digit ratio’

Barack Obama will soon become the 7th ‘left-handed’ US president in history. The continued-discussion about the high number of ”left-handed’ US presidents became a little bit quite the past 8 years – George W. Bush was the first ‘right-handed’ US president after Jimmy Carter! (1977-1981) However, with the left-handedness of Barack Obama will likely fire-up this discussion again. By the way, John McCain is a ‘lefty’ as well!

Only recently a research was published at the University of Melbourne which reported that left-handednes can be linked to a ‘masculine’ digit ratio – which implicates that the length of the index finger is short than the length of the ring finger. The photo below illustrates that this hand-feature is also present in Barack’s left hand! And by the way, his right has the same characteristic.

Finger length shows your talent for math / literacy.

The Melbourne research finding is especially interesting in the perspective of the theory which links left-handedness to an overabundance of testosterone in the womb; this theory was published in 2004 in New Scientist. For, an important aspect of John Manning’s digit ratio research links low 2D:4D digit ratio to an overabundance of testosterone in the womb as well!

How to measure digit ratio!

The picture on the right provides some detailed guidelines to assess the digit ratio of Obama’s left. The 2D:4D digit ratio of his left hand is likely to be in the zone: 0.90 – 0.92. A very ‘masculine’ finger length ratio!
