advantage of their expensive = good reaction to the inflated figure.
    By no means is my friend original in this last use of the expensive = good rule to snare those seeking a bargain. Culturist and author Leo Rosten gives the example of the Drubeck brothers, Sid and Harry, who owned a men’s tailor shop in Rosten’s neighborhood in the 1930s. Whenever Sid had a new customer trying on suits in front of the shop’s three-sided mirror, he would admit to a hearing problem and repeatedly request that the man speak more loudly to him. Once the customer hadfound a suit he liked and asked for the price, Sid would call to his brother, the head tailor, at the back of the room, “Harry, how much for this suit?” Looking up from his work—and greatly exaggerating the suit’s true price—Harry would call back, “For that beautiful, all wool suit, forty-two dollars.” Pretending not to have heard and cupping his hand to his ear, Sid would ask again. Once more Harry would reply, “Forty-two dollars.” At this point, Sid would turn to the customer and report, “He says twenty-two dollars.” Many a man would hurry to buy the suit and scramble out of the shop with his expensive = good bargain before poor Sid discovered the “mistake.”
    Jujitsu
    A woman employing the Japanese martial art form called jujitsu would use her own strength only minimally against an opponent. Instead, she would exploit the power inherent in such naturally present principles as gravity, leverage, momentum, and inertia. If she knows how and where to engage the action of these principles she can easily defeat a physically stronger rival. And so it is for the exploiters of the weapons of automatic influence that exist naturally around us. The profiteers can commission the power of these weapons for use against their targets while exerting little personal force. This last feature of the process gives the profiteers an enormous additional benefit—the ability to manipulate without the appearance of manipulation. Even the victims themselves tend to see their compliance as a result of the action of natural forces rather than the designs of the person who profits from that compliance.
    An example is in order. There is a principle in human perception, the contrast principle, that affects the way we see the difference between two things that are presented one after another. Simply put, if the second item is fairly different from the first, we will tend to see it as more different than it actually is. So if we lift a light object first and then lift a heavy object, we will estimate the second object to be heavier than if we had lifted it without first lifting the light one. The contrast principle is well established in the field of psychophysics and applies to all sorts of perceptions besides weight. If we are talking to a very attractive individual at a party and are then joined by an unattractive individual, the second will strike us as less attractive than he or she actually is. 8
8 Some researchers warn that the unrealistically attractive people portrayed in the popular media (actors, actresses, models) may cause us to be less satisfied with the looks of the genuinely available romantic possibilities around us. For instance, one study demonstrated that exposure to the exaggerated sexual attractiveness of nude pinup bodies (in such magazines as Playboy and Playgirl ) causes people to become less pleased with the sexual desirability of their current spouse or live-in mate (Kenrick, Gutierres, & Goldberg, 1989).
    Another demonstration of perceptual contrast is sometimes employed in psychophysics laboratories to introduce students to the principle. Each student takes a turn sitting in front of three pails of water—one cold, one at room temperature, and one hot. After placing one hand in the cold water and one in the hot water, the student is told to place both hands in the room-temperature water simultaneously. The look of amused bewilderment that immediately
