Left Brain vs Right Brain Quiz 🧠

Logic vs creativity, analysis vs intuition — explore the science of your brain!
In 2013, researchers at the University of Utah analyzed brain scans from 1,011 people aged 7 to 29 and found no evidence that individuals are predominantly “left-brained” or “right-brained.” While specific brain functions do lateralize to one hemisphere, whole-brain dominance is a neuromyth. This 50-question quiz tests what you know about hemispheric science, cognitive biases, neuroplasticity, and the real facts behind popular brain myths.
When University of Utah neuroscientists scanned 1,011 brains in 2013, they expected to find patterns of hemispheric dominance — instead they found none. The popular notion of “left-brained” logical thinkers and “right-brained” creatives turns out to be a neuromyth, even though specific functions genuinely do lateralize to one side.
Each round presents 10 randomized multiple-choice questions drawn from a pool of 50, so every playthrough is different. You get instant feedback with explanations after each answer, plus a shareable score at the end.
You'll discover why the left/right brain myth persists despite scientific debunking, what split-brain research actually revealed, how neuroplasticity allows London taxi drivers to grow their hippocampi, why we have roughly 86 billion neurons (not 100 billion), and how cognitive biases like the Dunning-Kruger effect and confirmation bias shape the way we think.
The idea that individuals are dominated by one hemisphere is a myth. A 2013 study of over 1,000 brain scans found no evidence for it. However, hemispheric lateralization of specific functions is real — language tends to be processed in the left hemisphere, while spatial reasoning and face recognition lean right.
No. Brain imaging shows virtually all regions are active over a 24-hour period. The brain consumes about 20% of the body's energy despite being only 2% of body weight — maintaining 90% unused tissue would be an enormous evolutionary waste.
In a corpus callosotomy, the bundle of 200–250 million nerve fibres connecting the hemispheres is severed. Roger Sperry's Nobel Prize-winning research on split-brain patients showed that each hemisphere can function independently, with its own perceptions, memories, and responses.
