We use the word typography to describe two different things: the design of letterforms, and the layout of typeset passages on a page. Both of those experiences are really important to communicating information, especially when that information involves complex ideas.
Michael BierutI actually think it almost works the other way sometimes: making a college textbook, say, look really "user friendly" tends to also make it look less "serious," even if nothing changes other than the design treatment.
Michael BierutFor instance, I assume those "carrots" we have on our keyboards were there originally to express "greater than" and "less than." Then they were adopted by coders, and now they show up all the time in the way email addresses are constructed. At least I think that's what happened.
Michael BierutI think that you could design a terrible logo for a good company with great people and they could build it into a great program. Alternatively you could design what seems to be a brilliant logo for people who are not smart or energetic or are incapable of associating with anything positive and it would become a terrible logo.
Michael BierutThe studies I've seen about readability and legibility tend to focus on a specific set of metrics: size, not just the point size, but things like the size of the lower case letters as a proportion of the overall letter height, and line length. People simply can't read really small type set in really long lines.
