The current title ("How to manipulate people with font type") relays two pieces of information about the article: that it is about fonts, and that it is about psychology (manipulation of people). The original article title does neither, at least to one who has not yet read the article--it could be about those inspirational posters, for all I know.
Though perhaps the title changed between our comments? I cannot tell.
I would be far more interested to know how similarly "easy-to-read" typefaces fared. Does an androgynous typeface like Helvetica have a different result than one more aligned with a gender? Does one with sharp aggressive serifs like the Copperplate family cause a different reaction than the smoother Garamond?
