A closer look

The exact moment you accidentally send an embarrassing typo to your boss, your brain imposes an involuntary speed limit on your fingers. Known as post-error slowing, or the Rabbitt effect, your anterior cingulate cortex detects the screw-up and slams the emergency brakes on your motor functions. It temporarily sacrifices your reaction speed in a desperate, evolutionary attempt to guarantee accuracy on your very next action, effectively turning you into a highly cautious turtle.
