Handedness is not one switch. Your brain assigns a side to each kind of task, and in some people those sides disagree. Pick what you actually do for every task below, not what you think you should do. Try the physical ones if you are unsure. Tap a choice again to clear it.
Would you add your answers to our research on mixed handedness? It is optional and anonymous, and your results appear either way.
Each side of the cortex drives the opposite side of your body; the cerebellum works on the same side. Areas light up where your answers place each skill. This is a map of where these skills are known to be controlled, not a scan of your brain.
