Hand Dominance Is Driven by Practice, Not Birth
New research from UCLA suggests that hand dominance is primarily shaped by practice and predictive brain models rather than innate biology.

The brief
A study indicates that dominant hand proficiency stems from repetition and the development of predictive brain models. These findings challenge the long-held theory that handedness is determined by mechanical superiority or birth-related biological wiring.
Coverage from outlets including StudyFinds, U.S. News & World Report, Neuroscience News, and the Santa Fe Institute emphasizes that the brain learns to favor one hand through consistent use. Additional reporting from Technology Networks, Earth.com, geneonline.com, and UCLA Health highlights the role of the brain in refining motor skills for everyday tasks.
Future developments will depend on how this research influences scientific understanding of motor control and learning. Coverage does not yet specify if or how these findings will impact existing neurological theories regarding lateralization.

Quick answers
What determines hand dominance according to the study?
The research identifies practice and the development of predictive brain models as the primary drivers of hand dominance.
Does biology play a role in handedness?
The study suggests that practice, rather than initial biological wiring or mechanical superiority, is the primary factor in determining hand proficiency.
Who conducted the research?
The study was conducted by UCLA.
