The book, Blink: The Power of Thinking Without Thinking, by Malcolm Gladwell, is a fascinating read about what happens with your thinking about a new person, thing, or event in the blink of an eye. One of the major takeaways is that your initial blink opinion about something is very often far more important than your opinion after a lot of research.
He brings a lot of business examples into the book including Coca-Cola (KO) and the Pepsi (PEP) taste test, and how the taste test is meaningless because people don't drink cola drinks blindfolded. He also mentioned how George Soros has a backache just before the stock market starts to turn against him.
