You Can Tell Men’s Promiscuity By Their Finger Length | Summary and Q&A

TL;DR

The length ratio between the second (index) and fourth (ring) fingers indicates testosterone levels and can reflect dating preferences.

Key Insights

• 🥳 Finger length ratio, influenced by testosterone, can provide insight into dating preferences in both animals and humans.
• 🫰 Monogamous species tend to have equal index and ring finger lengths, while promiscuous species show deviations, with shorter index fingers among males.
• 🖐️ Finger length measurements should be taken accurately at the joint between finger and hand bone, as visual inspection can be misleading.

talk to me about how you can tell the dating preferences of a society based on the ratio of their fingers um it sounds bizarre doesn't it but it seems to work quite well and and this was established um both in in animals and in in humans it works quite well in primates but it seems that the genes that control the length of the fingers and particula...

Questions & Answers

Q: How can finger length reveal information about dating preferences?

Finger length, especially the ratio between the second and fourth digits, is influenced by testosterone levels. A shorter index finger is linked to higher testosterone, suggesting a propensity for promiscuity.

Q: Are there any specific examples of species exhibiting different finger lengths based on mating systems?

Yes, monogamous species, like gibbons, have equal index and ring finger lengths. Promiscuous species show a deviant finger ratio, with the more promiscuous sex having shorter index fingers compared to females.

Q: Can finger length be easily determined by visual inspection?

Finger length differences are relatively small and may be hard to discern visually. Accurate measurement requires finding the joint between the bottom finger bone and the top end of the first hand bone.

Q: Are there potential implications of finger length beyond dating preferences?

Yes, high testosterone levels associated with a shorter index finger can influence behavior not only in romantic relationships but also in areas like work, where individuals may display more assertive and competitive traits.

Summary & Key Takeaways

• Finger length, particularly the ratio between the second and fourth digits, is influenced by testosterone levels during fetal development.

• A shorter index finger is associated with higher testosterone levels, indicating a likelihood for promiscuity.

• Monogamous species tend to have equal index and ring finger lengths, while promiscuous species have a more deviant finger ratio among males.
