📋 What it is
A perception scientist explains WHY an illusion fools us by figuring out which shortcut the brain used.
🗣️ Coach says
This is the whole perception-scientist mindset. The brain uses clever SHORTCUTS to see fast (assuming light comes from above, judging by context, filling gaps). An illusion is a case where a shortcut misfires. Explaining an illusion means naming the shortcut it exploits — turning "whoa!" into real understanding.
🧠 Memory hook
Explain an illusion by naming the brain SHORTCUT it exploits (light-from-above, context, gap-filling).

What did the convex lens say to the concave lens?
"You're so negative — I always try to focus on the positive!"
😲 Whoa!
The brain assumes light comes from above (because the Sun does) — so simply flipping a photo of craters upside-down can make them look like bumps.
✅ Quick check: Why does the brain use "shortcuts" to see, if they can cause illusions?
Say your answer out loud first — then reveal.
Shortcuts let it interpret the world instantly; they’re right almost always — illusions are the rare cases they misfire.
Perceptual shortcuts trade rare errors for speed.
