Mara stared at the image on her phone: a web of matchsticks forming overlapping squares beneath bold text that read, “The number of squares you see determines if you’re a narcissist.” She smirked, certain she’d breeze through the little challenge. Counting quickly, she typed her answer into the comment box, confident in both her sharp mind and her self-awareness. But as replies flooded in, people argued over the correct count. Some insisted there were twelve squares, others claimed sixteen, a few even found more hidden within the design. Mara reopened the picture and slowed down, tracing each line carefully. With every recount, her certainty wavered. It wasn’t just about squares anymore — it was about how easily she had assumed she was right the first time.

Later that night, she realized the puzzle wasn’t really measuring narcissism at all. It was revealing something quieter and more human: how quickly people trust their first perception, how reluctant they are to admit they might have missed something, and how defensive they become when challenged. The image hadn’t diagnosed personality flaws — it had mirrored behavior. Mara smiled, saving the picture. Not as a test, but as a reminder that perspective changes everything. Sometimes, the squares you fail to see aren’t in the picture — they’re in the assumptions you didn’t know you were making.
