![]() Increased risk of central and visceral obesity.It’s okay if your ring finger is bigger than your index finger, that is, a bigger 2D:4D. What If My Ring Finger Is Bigger Than My Index Finger? That is why the index-to-ring is such a strange phenomenon since it has a great density of experimental evidence in animal models, and observational evidence in humans, which correlates it with certain aspects such as those previously described, in a sufficiently homogeneous way to think it may be a real cause. Something that has not been rigorously demonstrated in any study carried out at a university of recognized transparency. This is part of the study of palmistry, a pseudoscience based on the fact that our hands contain relevant information about our health, the way we are, how we behave, and our future. The finger theory is nothing more than a colloquial way of describing the phenomenon that associates the 2D:4D ratio to certain characteristic features when, in principle, there should be no reason to do so. Your Hand Speaks About You: Finger Theory ![]() In certain studies, it has been associated with sexual preferences of men with less masculine appearance and/or women (homosexuality), polycystic ovary syndrome, more assertiveness, ability to make relevant decisions, and athletic performance. With a statistically significant difference, which means that in a homogeneously distributed way, men have a lower ratio than women. Tendency towards polygamy or infidelitiesĪccording to a study at the University of Alberta where this relationship was related to some health markers, in humans, the average is:.Greater leadership and group management skills.Increased traits derived from addictions.Increased risk of diseases characteristic of the male sex (cardiovascular, prostate cancer, etc.).Lower 2D:4D Ratio, What Does It Mean?Ī value less than 1 is characteristic of men, and is associated with: Said like this, it seems strange and it certainly is, but there are quite a few studies that show a relationship between 2D:4D and physical, psychological, and behavioral traits typical of an androgenic or estrogenic environment depending on the value obtained. It is used to assess the degree of the “masculinity” trait that you present. However, there is another group of scientists who believe that those who investigate the 2D:4D ratio are falling for a simplistic and misleading idea. Especially those who doubt emphasize that the difference in the radii of the fingers between men and women is an illusion, and even consider that there should be skepticism in all studies that use this measure. Some scientists have even tried to determine the radius of the hands that appear in ancient caves to establish whether those ancient paintings were made by men or women. But this field has been taken much further than he could have imagined. In 20 years, more than 1,400 studies have appeared that relate all kinds of personality attributes or defects to the radius of the fingers. For example character traits, cognitive abilities, sexual orientation, cardiovascular diseases, and even cancer. Where did the 2D:4D Ratio Come from?īiologist John Manning was one of the first to propose that the radius of human fingers can reveal a lot about a person, back in 1998. To calculate it, you only have to measure the length of both fingers, from the base (carpometacarpal joint) to the tip (end of the last phalanx), and divide the length of the index by that of the ring finger. It is the term that describes the relationship between the length of the second (digit 2, 2D, or index) and the fourth finger (digit 4, 4D, or ring).
