Why do people read negative Internet comments and do other things that will obviously be painful? Because humans have an inherent need to _1_ uncertainty, according to a recent study in Psychological Science. The new research reveals that the need to know is strong that people will _2_ to satisfy their curiosity even when it is clear the answer will _3_.
In a series of experiments, behavioral scientists at the University of Chicago and the Wisconsin school of Business tested students’ willingness to _4_ themselves to unpleasant stimuli in an effort to satisfy curiosity. For one _5_, each participant was shown a pile of pens that the researcher claimed were from a previous experiment. The twist? Half of the pens would _6_ an electric shock when clicked.
Twenty-seven students were told with pens were electrified; another twenty-seven were told only that some were electrified. _7_ left alone in the room. The students who did not know which ones would shock them clicked more pens and incurred more shocks than the students who knew that would _8_. Subsequent experiments reproduced this effect with other stimuli, _9_ the sound of fingernails on a chalkboard and photographs of disgusting insects.
The drive to _10_ is deeply rooted in humans, much the same as the basic drives for _11_ or shelter, says Christopher Hsee of the University of Chicago. Curiosity is often considered a good instinct—it can _12_ new scientific advances, for instance—but sometimes such _13_ can backfire. The insight that curiosity can drive you to do 14 things is a profound one.
Unhealthycuriosity is possible to _15_, however. In a final experiment, participants who were encouraged to _16_ how they would feel after viewing an unpleasant picture were less likely to _17_ to see such an image. These results suggest that imagining the _18_ of following through on one’s curiosity ahead of time can help determine _19_ it is worth the endeavor. “Thinking about long-term _20_ is key to reducing the possible negative effects of curiosity,” Hsee says. In other words, don’t read online comments.
