Summary
People often claim they "knew it all along" after receiving feedback on errors. This study confirms that high-confidence errors are indeed remembered better, supporting the hypercorrection effect.
Area of Science:
- Cognitive Psychology
- Memory and Learning
Background:
- The hypercorrection effect describes how high-confidence errors are corrected more easily than low-confidence errors.
- The "knew it all along" phenomenon is a common explanation for this effect, but its validity has been debated.
Purpose of the Study:
- To investigate the validity of the "knew it all along" explanation for the hypercorrection effect.
- To determine if individuals genuinely possessed prior knowledge of correct answers for high-confidence errors.
Main Methods:
- Experiment 1: Assessed participants' claims of prior knowledge after receiving feedback on errors.
- Experiments 2 & 3: Utilized second-guess tests, free recall, and cued recall (including scaffolded feedback) to assess actual knowledge of correct answers.
Main Results:
- Participants were more likely to claim they "knew it all along" for high-confidence errors.
- High-confidence errors were more likely to be correctly answered in subsequent tests and recall tasks.
- Scaffolded feedback revealed that participants needed fewer prompts to recall correct answers for high-confidence errors.
Conclusions:
- The "knew it all along" claims are largely accurate, reflecting genuine prior knowledge.
- This pre-existing knowledge facilitates the easier correction of high-confidence errors, supporting the hypercorrection effect.

Hindsight Biases
Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?
Confirmation Biases
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?
Fundamental Attribution Error
According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is called the fundamental attribution...
Unrealistic Optimism Bias
Unrealistic optimism bias is the tendency to overestimate the likelihood of positive outcomes. This cognitive bias makes individuals believe they are less likely to experience failures, setbacks, or risks and more likely to succeed than others. For example, people may assume they are less prone to health issues, accidents, or financial struggles than their peers, even when they share similar risk factors.One key component of this bias is the above-average effect, where individuals perceive...
Self-Evaluation: Self-Enhancement and Self-Verification
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
Self-Presentation: Self-Monitoring and Self-Handicapping
People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about the way you...
