I actually found an article in the bookstore last night on different fonts! Who would have thought! The article (from a marketing text) explained why one should use Times New Roman. It said that the choice of typeface can affect a reader's comprehension. Roman letters are preferred by most readers because they are the most comprehended, and can be understood 92% if the time. A close second is sans serif at 90%. The least comprehended --anything close to cursive or script. Such letters are only understood between 37% and 26% if the time.
I just love statistics.
