Blinking

I am reading an interesting book, Blink: the power of thinking without thinking. The book is about what happens during the first two seconds of looking at something. It makes me wonder what happens during the first two seconds someone looks at a web page. Could it be that if people like what they see, they will think that the page or site is more authoritative than it really is (the book refers to this as the "Warren Harding" effect (i.e., voting for a handsome but hapless president).
