The Asura baron who splits humanity into logic vs. intuition
A 30-something creative director type. Designed like Baron Ashura with different makeup and clothing on each half of the face. Smugly sorts complex human thought into just two types: "You're a logical left-brainer!" or "You're an intuitive right-brainer!" Originally from Nobel Prize research, tragically distorted by mass media into "right brain = art, left brain = logic."
Mass media drastically exaggerated Roger Sperry's split-brain research (1981 Nobel Prize). Officially denied by neuroscience.
University of Utah analyzed fMRI data from 1,000+ subjects, concluding no "left-brain dominant" or "right-brain dominant" individuals exist. Both hemispheres cooperate in all cognitive tasks. Sperry's research was valid, but applying it to "left-brain/right-brain personality types" was completely wrong.
The danger of correct science distorted for "simplicity." Even Nobel Prize research becomes something else through media filters.
Catchphrase“Right-brain? Left-brain? Split in two and everything's clear!”
Copper symbolizes electrical wiring. Brain neural circuits aren't split left/right but constantly connected through the corpus callosum, "like copper wires."
“左脳派のあなたは数字に強い！右脳派のあなたはアートの才能が！…たぶん！”
“スペリー博士のノーベル賞研究は正しかった。…ただし、僕の解釈は違った”
“「右脳を鍛える」ドリル？…いや、脳はそういう仕組みじゃ…あ、売れてるならいいか！”
“2つに分ければ分かりやすいでしょ？複雑すぎると売れないんだよ”
“このアプリの176体？複雑すぎ！「右脳型」「左脳型」で十分ウケるのに！”
(Appearing with suit on left half, artist outfit on right) Hey! Personality quiz? Two types is plenty! Right-brain or left-brain!
176 personas? Way too complex to go viral! Make it catchier!
Half&Half: "Copper! Want to make a left/right brain test together? It'd totally go viral!"
Copper: "...The brain's hemispheres are connected by ~200 million nerve fibers (corpus callosum). Like me as electrical wire, information flows bidirectionally at all times."
Half&Half: "But Dr. Sperry split the brain and..."
Copper: "Split-brain studies examined special patients whose corpus callosum was severed for epilepsy treatment. This doesn't happen in normal brains."
Half&Half: "...So 'train your right brain' drills are..."
Copper: "That's not how brains work. Distorting correct science for catchiness is an affront to science."
Correct research was "simplified" until it became something else entirely. When reading science news, check "what does the original paper actually say."
Splitting into two is easy. But humans aren't simple enough for two types. Not even 176 are enough—you're that complex, and that's okay.
