3 Points & a question

White
• When using lining figures, a designer unintentionally makes numerals stand out because they look like capital letters. Old style figures should be used for numerals instead because they look like lowercase letters and flow with the text.
• The contrast between letters of a word and the space surrounding them make the type legible (or not).
• Neither complexity nor simplicity (in typeface) will successfully relay a message—the former tends to be illegible, while the latter takes away from the importance of the content. Rather it is the combination of complexity and expressiveness that “will make the message both legible and interesting.”

Question:
Are Maitra and Goswami, through their article/study, suggesting that Americans change both the way we design documents and the way we read/interpret them? Will changing the document design process automatically force us to change the way we read a document?
