Since the Spotlight Effect is the guiding effect for a person and by using effective predictions, another aspect comes into play in how a person predicts that his hypothetical future will affect her on an emotional level, and this is an impact bias. This is how we think we will emotionally perceive an event and that it will be much worse than it could actually be. The article goes on to discuss a study conducted by Tom Gilovich in which college students were required to wear a Barry Manilow t-shirt to class. Although the actual experiment focused on the spotlight effect, the impact bias could also have been measured in this experiment. For example, students could have been asked how they thought it would go when they entered the classroom, and then they could have compared those feelings to what they actually experienced when they actually entered the classroom. . In the end it might turn out that the experience had not been as bad as they had thought it would be, and that their resilience had been stronger than they had thought.
