Chapter 26. Flaws in our ability to see the answer Our intuition and instincts can mislead us in some important ways unless we are alert to avoiding them. Our brains are very useful organs in solving problems. Merely relying on intuition to solve a problem or make the right choice has some well-known limitations, however. Optical illusions and magic tricks are examples familiar to all of us in which appearances are deceiving. Consider the following picture: The straight line appears to be AB, but it is really AC.

Of course, we know well that people collect items previously owned by the rich and famous. The fact that the desirability of an item is based on its , history of previous ownership reflects just how strongly we respond to associations. Advertisers use this principle effectively. Endorsements of a product by someone famous is now routine and begets the personality high dollars (e.g., Michael Jordan endorsing shoes, football players endorsing beer, Elizabeth Taylor endorsing her perfumes; the movie “Attack of the Killer Tomatoes” portrayed an ad in which Jesus Christ endorsed an electronics company).
