Daily Brain & Mind — Day 10 (Optical Illusion)
🧠 Müller-Lyer Illusion (Which Line is Longer?)
Look at the two lines: one has arrows pointing outward (>---<), while the other has fins pointing inward (<--->). Which horizontal line is longer?
💬 Be honest: did the line with outward wings look significantly longer to you? (Solution in first comment 👇)

💡 SCIENCE BEHIND THE ILLUSION:
Both lines are mathematically identical in length! Franz Carl Müller-Lyer discovered that our brain's depth-estimation system interprets outward fins as the far corner of an interior room, and inward fins as the near exterior corner of a building, stretching the perceived length.
