Can finger length predict infidelity?

[tweetmeme source=”handresearch” only_single=false] Earlier this year Dr. Phil and his panel of medical experts discussed the new science behind a cheater’s brain and what can be done if your loved one is at a higher risk. Author of Change Your Brain, Change Your Body, Dr. Daniel Amen, author of Insatiable Wives, clinical psychologist Dr. David Ley, Claremont University’s Dr. Paul Zak and author of The Male Brain, neuro-psychiatrist Dr. Louann Brizendine explain how you can discern a man’s risk for infidelity and the treatment options to lower his risk. Studies have indicated that the ‘Casanova-type’ finger ratio (low 2d:4d) is often seen in polyandry + polygyny populations, and …men who cheat!

Dr.Phil.com presents a 4 item list of physiological indicators that your han is at a higher risk for cheating:

  • Length of ring finger compared to pointer finger: The length of a man’s ring finger is linked to testosterone in utero and during puberty. A longer ring finger means more testosterone, and the increased likelihood of a greater number of sex partners and a higher risk of cheating.

  • Facial symmetry and size of jaw: If one side of a man’s face matches the other side, is symmetrical, the more it is an indicator to women that that man has high genetic value. Men whose faces are more [symmetrical] are more likely to have more partners because more women want to have their children.
  • Size of penis: If a male is well-endowed, that means more testosterone and a higher risk of cheating.
  • Brain injuries: Men with a history of engaging in impact sports like football or martial arts, or men who’ve had a history of concussions are at a higher risk. Also, men with disorders like ADD or bipolar disorder have low pre-frontal cortex activity or hyper-frontal activity, which could mean less ability to stop impulsive behaviors, like cheating.

So, how surprising is it really that Casanova had as well the long ring finger !?

What does finger length say about athletic ability? In a BBC project “Secrets of the Sexes” John T. Manning risked his reputation by participating in an experiment with six athletes: all 5000 meters specialists… the outcome is simply astonishing!

Professor John T. Manning explains how finger length relates to testosterone & athletic behavior.

Professor John T. Manning explains:

“… What I should be able to do is look at the differences between the ring finger and index finger, and on that basis rank these runners: first, second, third, fourth and so on. In theory that should work.”

Comment voice explains:

“In practice we’re providing professor Manning with photocopies of the athletes hands. And in return he’s risking his reputation by providing us with the results of a race that has yet to be run.”
