People don’t have a “natural frequency” is the real answer.

I won an Xbox 360 a long time ago from a Coca Cola competition. You had to use codes from the bottle caps and then quickly answer some quiz questions correctly. But you had unlimited tries. So I just kept clicking random answers quickly until I got all questions right at a ridiculously low time.

Good times. Borrowed Guitar Hero, LA Noire, Batman Arkham Asylum and Red Dead Redemption at the library, had a blast.
