Metacognition is broadly defined as 'thinking about thinking' or the ability to monitor and evaluate one's own cognitive processes. It involves reflecting on how well we perform mental tasks, such as judging our confidence in a memory or realizing we made a mistake during a decision. By evaluating our thoughts, we can adjust our strategies to improve learning and decision-making.
Understanding metacognition is vital because it determines how people self-regulate their learning, study habits, and everyday choices. Misjudging our own knowledge can lead to costly errors, whereas accurate metacognitive awareness helps us allocate mental resources more effectively. In clinical, educational, and everyday settings, measuring metacognition helps psychologists identify how people navigate uncertainty and learn from mistakes.
Evidence
What the evidence shows
Drawn from 6 studies in this library. Each finding starts with a plain-language takeaway, then the denser detail. Supports means evidence for a finding; Challenges means evidence against a stated position; Qualifies marks scope with a short note on each study’s contribution. Challenged positions are labeled — they are not findings.
Metacognitive abilities appear to be largely domain-general, as an individual's self-evaluation accuracy and confidence ratings are significantly correlated across different types of mental tasks.
Self-evaluations made after a decision (retrospective judgments) are significantly more accurate than predictions made before or during a task (prospective judgments).
Metacognitive accuracy can be enhanced through targeted, adaptive feedback training on confidence ratings, and these improvements can transfer to entirely untrained tasks.
Metacognitive monitoring can operate even when decision performance is at chance level, showing that individuals can discriminate between their correct and incorrect answers without performing well on the primary task itself.
Open questions
Tensions and limits
Some items are genuine disagreements on the same question. Others mark different assays, populations, or outcomes — limits on how far one study travels — not a forced fight between papers.
There is disagreement regarding whether aging causes a decline in trial-by-trial metacognitive efficiency; one study found a significant age-related decline in visual self-awareness, while another study using performance-matched adaptive tasks found that local metacognitive efficiency remained completely intact across age groups.

Common misconceptions
You must perform well on a cognitive task to have accurate self-awareness about whether your choices are correct.
People can exhibit 'blind insight,' where they accurately distinguish between their correct and incorrect decisions even when their overall task performance is completely at chance.
Metacognitive monitoring skills are fixed traits that cannot be improved.
Providing targeted, point-based feedback on the accuracy of confidence ratings can systematically train and improve a person's metacognitive calibration, and these gains transfer to untrained tasks.
Judging your confidence before a decision is just as accurate as judging it after.
Metacognitive judgments are significantly more accurate when made retrospectively rather than prospectively, as post-decisional cues boost accuracy.
Aging uniformly degrades all aspects of self-evaluation and cognitive confidence.
While older adults report lower global confidence and global self-estimates of their performance, their local, trial-by-trial metacognitive efficiency can remain completely stable compared to younger adults.
Exam-style questions
Short-answer questions that ask you to explain or compare, not recall.
Compare and contrast prospective and retrospective metacognitive judgments. Which is generally more accurate, and why might this be the case?
Prospective judgments are made before a decision or outcome is finalized, whereas retrospective judgments occur after the choice has been made. Retrospective judgments are significantly more accurate. This superiority exists because retrospective judgments can utilize rich post-decisional cues, physical feedback from making the response, and cognitive feedback generated during the decision-making process, which are unavailable prior to the decision.
Explain the phenomenon of 'blind insight' and its theoretical implications for models of metacognition.
Blind insight refers to the finding that individuals can accurately judge whether their decisions are correct or incorrect even when their primary task performance is at chance level. This implies that metacognitive sensitivity can operate independently of primary decision accuracy, suggesting that the brain can track confidence signals even when task-level information is too weak to support correct primary decisions.
What does it mean for metacognition to be 'domain-general' versus 'domain-specific', and what evidence supports domain-generality?
If metacognition is domain-general, an individual's self-evaluation accuracy relies on a shared cognitive resource across different tasks (e.g., memory and visual perception). If it is domain-specific, self-monitoring depends on the processes of each specific task. Evidence supporting domain-generality includes significant positive correlations in metacognitive efficiency across memory and perception tasks, and the transfer of metacognitive training from visual tasks to untrained memory tasks.
How does healthy aging affect global metacognitive bias compared to local metacognitive efficiency?
Healthy aging is associated with a decrease in global metacognitive bias, meaning older adults generally report lower overall confidence in their abilities before and after tasks. However, their local metacognitive efficiency—their ability to accurately distinguish between correct and incorrect answers on a trial-by-trial basis—remains intact and does not significantly decrease with age, particularly when task difficulty is matched using adaptive staircases.
The studies
6 studies in this library bear on Metacognition, ordered by citations.
- Can we train ourselves to judge our own minds better?
Providing targeted feedback on the accuracy of people's confidence ratings can improve their overall ability to monitor their own performance, even on completely untrained tasks.
- Does our ability to judge our own performance decline as we age?
While older adults can perform visual tasks just as accurately as younger adults, their ability to judge the accuracy of their own decisions decreases over time.
- Is our ability to judge our own minds general or task-specific?
An individual's ability to accurately evaluate their own performance is largely shared across different mental tasks, supporting a domain-general metacognitive ability.
- Are We More Accurate at Judging Future or Past Decisions?
People are significantly better at judging the accuracy of their decisions after they have made them compared to beforehand.
- Can people know they are right when they are guessing?
People can accurately judge whether their decisions are correct even when their overall decision accuracy is completely at chance.
- Does our self-awareness change as we grow older?
As people age, their overall confidence in their performance decreases, but their actual ability to evaluate individual decisions remains just as accurate.
