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 !?

Another finger secret:

Your fing length ratio (2D:4D) appears to be related to prenatal testosterone and estrogen levels and pubertal face growth. Several studies have recently provided evidence that 2D:4D is associated with other-rated facial masculinity and dominance, but not with facialmetric measures of masculinity. The researchers found that localized face shape differences, shown here to be sexually dimorphic and related to ratings of dominance, were associated with direct and indirect measurements of 2D:4D.

In this study Robert P. Burriss, Anthony C. Little, & Emma C. Nelson examined various localized features of the face, showing nose width, jaw angle, and lip height to be sexually dimorphic.

The researchers from Research reported from The University of Liverpool (+ Stirling University) then had faces rated for dominance and saw that the most dimorphic characteristics were those most associated with rated dominance, with typically masculine characteristics tending to be associated with high ratings of dominance.

Finally, 2D:4D measurements were made using three different techniques. High (feminine) values of 2D:4D were associated with feminine facial characteristics in women, but not in men. It was concluded that certain aspects of facial development are governed by factors that are established prenatally.

These aspects may be associated with perceptions of the self by others that are important in the social environment, particularly in terms of intra-sexual competition and mate acquisition.

ABOUT SEXUALLY FACIAL CHARACTERISTICS:

Adult males have shorter up­per faces, for their width, than fe­males do, re­search­ers found. This male face is wid­er, as ap­par­ent from the yel­low ver­ti­cal lines when he is com­pared to the face above. Yet the up­per fa­cial height is about the same, as is ev­i­dent when com­par­ing him to the face left of him. The re­search­ers placed the yellow lines against fa­cial ref­er­ence points known as the na­si­on, zy­gion and pros­thi­on, shown at up­per left.
