Whats the psychology behind this

I didn't pick 17... What's that mean?

that's interesting, but what do you think of this?

I watched this twice. It was only right the first time.

Between 1 and 20, 17 is prime, which means it isn't coming up in any of your memorized multiplication tables, it isn't right next to either extreme like 19, but is on the high side, which means it's further from 1 as you count up. I think all of these factors combine subconsciously to make many people pick 17 when trying to think of a "random" number due to a common misunderstanding of "random" to mean "unlikely to be guessed".

Heh. I started with 17 and immediately switched to 16. IN YOUR FACE.

🤷🏻‍♂️🤷🏻‍♂️🤷🏻‍♂️

Wtf?

I picked 19…

BRO WTFFFFFFFFFFFFFF

Wtffffff perhaps because at the very beginning his finger was pointing at 17, subconscious selection?
