The New York Times article explains how consumers are manipulated by the design of Doritos. Specifically, multiple elements of the chips are created to be physically and psychologically appealing which increases consumption. Naturally, consumption of junk food is not good for one’s health.
Obviously the researchers at Doritos are not really concerned at all with “finding significant truths” and simply want to be able to predict and manipulate consumers’ eating habits. However, an in-depth investigation of how junk food companies increase both consumption and health problems is perhaps more likely to “”find significant truths.”
