This gets repeated over and over, but if you look at the literature, empirical studies are split between _may_ slightly help to no observable difference. Where things get interesting are studies that take into account letter spacing, they show that Comic Sans spacing may somewhat help. Still, if you apply the same spacing to a regular font, accuracy increases about the same. The accuracy increase is so minimal that it probably presents no practical advantage AFAICT.
