Sex difference research illuminated.

Created in 2020 by Zachary Elliott, the Paradox Institute is an independent science education group focused on helping people learn about the biology of sex and the differences between males and females.

From cleanly illustrated animated videos to long form essays, we provide digestible, scientific content on the most fundamental and controversial research in the biology of sex differences.



Science denial confronted.

In an age where the very existence of male and female are being denied, we provide evidence, reason, and clarity to both simple and complex topics in the biology of sex.

The content presented is directly informed by scientific literature from the fields of evolutionary and developmental biology, endocrinology, personality psychology, and neuroscience.
