Tag: Biological sex

The National Institutes of Health defines biological sex as "a multidimensional biological construct based on anatomy, physiology, genetics, and hormones". The single term that refers to the biological anatomical differences between females and males is **sex**, a fundamental aspect of human biology that influences development, health, and more. This article explores the scientific underpinnings of this concept.

While some studies have shown subtle statistical differences in average finger length ratios between sexes, these are far too inconsistent and overlap too much to be used for individual prediction. The idea of using finger length to accurately predict or determine a person's gender is a misconception, as individual variation is vast and influenced by many factors.

Despite persistent folk tales and common misconceptions, there is no reliable, scientifically valid method for how to tell gender by hands. In reality, a person's hands are not a roadmap to their gender identity, and attributing specific traits to one gender is a form of pseudoscientific stereotyping.
