From Malcolm Gladwell's Q&A about his new book, Blink:
It's a book about rapid cognition, about the kind of thinking that happens in a blink of an eye. When you meet someone for the first time, or walk into a house you are thinking of buying, or read the first few sentences of a book, your mind takes about two seconds to jump to a series of conclusions.
I really wonder how useful those first seconds are in making quality decisions about complex problems or issues. Also, how do we learn in such instances?
