Finally -- Explanations for Many Optical Illusions
December 18, 2007
Advertisers, comedians, filmmakers and many others use standard techniques to get you to see things a certain way. Once you learn their inner secrets, you can use this knowledge to keep yourself from being fooled.
1. Forced Perspective: Objects, such as in movies or theme parks, can be made to look larger, smaller, closer, or farther away than they really are.
2. Fisheye Lens: This camera angle makes objects look much larger than they really are (it’s a favorite among realtors).
3. Illusion of More: Many food packages only let you see the bottom portion of the contents, making it seem like the entire bag is full (when in reality it’s not).
4. Selling Air: Many “light” food products, such as light ice cream and whipped yogurt, have fewer calories because they have air added. A gallon of light ice cream could actually contain up to half a gallon of air.
5. Product Placement: In movies, on sweatshirts and even by hiring fake customers to talk about a certain product, advertisers love to place their products where consumers will unconsciously let them sink in.
6. The Audience Plant: During comedy routines, live TV shows and other acts, some audience members may be paid actors hired to respond in a certain way (and get the rest of the audience to respond that way as well).
