What Are Cognitive Biases That Affect Mental Health?
A friend sends a short reply to a message. You notice the absence of their usual friendly greeting, interpret the response as a sign that something is wrong and later remember the exchange more readily than the friendly conversations you had earlier that week. Nothing about the message necessarily confirms your interpretation. Several processes have influenced what you noticed, what you concluded and what you subsequently remembered.
Cognitive biases are systematic tendencies in the way information is selected, interpreted, retained or used in judgment. They are not necessarily deliberate choices. Some arise from processes that ordinarily help people handle complex information efficiently. Their consequences depend on the circumstances and the particular tendency involved.
A cognitive distortion is a related but somewhat different concept commonly used in psychological therapy to describe unhelpful patterns of thought, such as interpreting an ordinary setback as an entirely disastrous outcome. A researcher investigating cognitive bias might instead measure how quickly participants notice threatening stimuli or how they interpret an ambiguous sentence. Our guide to cognitive distortions examines those familiar thought patterns in detail.
The research discussed here focuses on attention, interpretation and memory. These processes may be associated with anxiety and depression, but they do not explain every mental health difficulty. Economic insecurity, illness, traumatic experiences and unsafe relationships can also contribute to distress. The purpose of identifying a possible bias is to investigate whether an interpretation is useful and adequately supported, not to dismiss a person’s experience.
Attention Bias: Why Some Information Captures Your Attention
Attention helps you select information from a complex environment. You cannot examine every detail of a busy street, a conversation and your own physical sensations with equal concentration at the same moment. Prioritizing a potentially important signal can be adaptive, particularly when that signal concerns immediate safety.
In a 2007 meta-analysis, Yair Bar-Haim and colleagues combined 172 studies involving anxious and nonanxious participants. Across the experimental tasks, anxious groups showed a greater tendency to attend to threatening material, with a moderate average difference between groups. Such findings do not establish that every anxious person attends to threats in the same manner.
Consider somebody preparing for a meeting. They notice a colleague’s expression of impatience but pay less attention to several other colleagues who appear interested. Afterwards, their account of the meeting centers on that single expression. It is possible that the colleague was impatient, but the selected information offers an incomplete representation of the event.
An attention bias is not the same thing as inventing information. The individual may accurately notice a genuine event while giving it disproportionate weight relative to other relevant events. Conversely, paying close attention to a real hazard may be entirely appropriate.
A useful response to a nonurgent concern is to examine whether other accessible information deserves attention. You might review what different colleagues actually said rather than attempting to decide what everyone felt from their expressions. Where a safety issue is involved, follow appropriate precautions rather than trying to redirect attention away from danger.
Interpretation Bias: What Happens When Information Is Ambiguous
Ambiguity creates room for several possible explanations. If a friend cancels an arrangement without offering much detail, they may be unwell, facing an unexpected responsibility or no longer interested in attending. Without further information, these possibilities cannot be distinguished confidently.
In a 2017 meta-analysis, Jonas Everaert, Ioana Podina and Ernst Koster examined 87 studies involving 9,443 participants. Depression was associated with differences in the interpretation of ambiguous information. The pooled association was substantial enough to merit attention, but findings depended strongly on whether interpretation was measured directly or indirectly.
The methodological distinction matters because expressing a negative interpretation and displaying a bias on an indirect experimental task may not measure identical processes. It is inappropriate to assume that a simple online questionnaire can determine precisely how an individual’s mind processes every ambiguous situation.
At work, a supervisor might request a brief conversation the next day. You may immediately imagine criticism, although the request could concern routine planning. Rather than substituting an equally unsupported positive prediction, you could acknowledge that several explanations remain possible and prepare for the meeting in a proportionate way.
This is not a requirement to assume that other people’s intentions are harmless. If prior evidence indicates mistreatment, that information should remain part of the assessment. A more balanced interpretation is one grounded in the available evidence, not necessarily the most reassuring interpretation.
When uncertainty repeatedly leads to prolonged worry, read our discussion of rumination versus worry for additional context.
Memory Bias: Why Your Recollections May Not Represent Everything That Happened
Remembering an experience involves more than retrieving a complete recording. People differ in what they notice at the time, which details become accessible later and how they understand those details in light of subsequent events.
A 2022 meta-analytic review by Jonas Everaert and colleagues examined 153 studies in its first analysis and identified a small overall association between depression and explicit emotional memory bias. The magnitude varied according to the materials and methods used. A separate analysis examined people in remission and found evidence of a bias under conditions involving mood or stress induction, but not a statistically reliable overall effect across all conditions.
Imagine reviewing your performance during an academic course. Several disappointing assignments come to mind immediately, while satisfactory work is less accessible. Those disappointments are genuine experiences. However, recalling them readily does not establish that the course was unsuccessful as a whole.
When an objective record exists, consulting it may help answer a specific question. Reviewing the actual grades or feedback is different from repeatedly trying to remember whether you performed adequately. Records also have limitations, but they can provide information that unaided recollection may not supply.
Be cautious about applying this principle to traumatic memories. A person’s distress deserves respectful attention, and ordinary memory research cannot determine whether a particular reported event occurred. A qualified trauma-informed professional may be appropriate when memories are causing intense or persistent distress.
The broader lesson is that the ease with which something comes to mind is not always a reliable measure of its frequency or importance.
How Cognitive Biases Can Interact
The processes of noticing, interpreting and remembering are related, but they do not necessarily operate as a single mechanism. If you notice an unfavorable expression during a meeting, interpret it as evidence of rejection and remember that interpretation later, the processes may appear to reinforce one another.
A 2022 systematic review by Chantel Leung and colleagues identified 36 articles examining combined cognitive biases in anxiety. Across the studies included in its quantitative analyses, correlations between different bias measures and effects of changing one bias on another were generally small. The relationship involving interpretation and memory was stronger than some other combinations.
These results suggest that interactions deserve investigation without assuming that one bias inevitably produces all the others. The experimental measures involved different tasks and populations, and the findings cannot predict an individual person’s reactions.
Consider someone who is concerned about attending a social event. They pay particular attention to quiet moments in conversations and interpret them as signs that they are unwelcome. When deciding whether to attend another event, those moments are easier to recall than conversations that went smoothly. Avoiding future occasions may then limit opportunities to acquire additional information.
This example illustrates one possible pattern, not a diagnosis. The person may have valid reasons to avoid a particular gathering, and their preferences should be respected. If they would like to participate in similar activities but repeatedly find fear prohibitive, professional guidance may help identify an appropriate approach.
An important implication is that changing everyday behavior or circumstances may provide new information even when a particular thought has not changed immediately.
Why These Patterns Appear Across Different Mental Health Conditions
Researchers sometimes use the term transdiagnostic to describe processes relevant to more than one diagnostic category. Attention to threat or a tendency to interpret ambiguity negatively may occur in people with different concerns. Their presence alone cannot establish which condition, if any, a person has.
A 2023 online publication of a systematic review and network meta-analysis examined 31 studies encompassing 4,401 participants across a range of psychiatric diagnoses. On average, clinical groups showed more pronounced cognitive biases than nonclinical comparison groups. The severity and type of bias varied by diagnosis, and memory biases were less frequently investigated than attention and interpretation biases.
The practical significance of this work is that a commonly discussed thinking pattern should not be used as a diagnostic shortcut. Social anxiety, depression, obsessive-compulsive disorder and other conditions have distinct features and may require different treatments. Even people with the same diagnosis may experience different difficulties.
A fictional person who repeatedly checks an ordinary message may be concerned about disappointing a manager. Another person may experience intrusive fears and repetitive behaviors that consume substantial time. Their outward actions could appear similar, while the circumstances and clinical needs differ.
Our article on mindfulness for anxiety discusses how recognizing repetitive concerns may be useful for some people. It also explains why an informal awareness exercise should not replace appropriate treatment.
If symptoms persist, describe their frequency, intensity and effect on your activities to a qualified professional. Those details can be more useful than attempting to identify your own diagnosis through a list of cognitive biases.
A Practical Way To Examine An Everyday Interpretation
Choose a nonurgent situation about which you have reached a conclusion despite incomplete information. Write down what you directly observed in one sentence. Then describe your interpretation in a separate sentence, using language that recognizes it as a conclusion rather than an established fact.
For example, your observation might be that a colleague did not reply to an ordinary question during the afternoon. Your interpretation might be that the colleague deliberately ignored you because they dislike working with you. The first statement describes an event. The second makes an inference about intention.
Next, consider what information would be relevant to evaluating that inference. Perhaps the colleague was attending appointments or the question was sent through a rarely monitored channel. You do not need to invent an exhaustive list of alternative explanations. Identify only the possibilities that are plausible given what you know.
Finally, select a proportionate response. A single courteous follow-up during normal working hours may be useful if the matter needs attention. Repeatedly contacting the colleague to obtain reassurance may not provide further benefit. In a professional or safety-critical context, continue to follow established verification procedures.
You can also consider what you have learned when additional information becomes available. If the original interpretation turns out to be accurate, acknowledging that fact is part of reviewing your judgment. The exercise is not designed to prove every negative thought wrong.
Keep the activity brief. If it encourages increasingly repetitive analysis or reassurance-seeking, stop and discuss the difficulty with a qualified clinician. A general educational exercise is not an individualized therapy protocol.
Do Cognitive Bias Modification Programs Work?
Cognitive bias modification is a family of research-based experimental interventions designed to influence certain patterns of information processing. Some tasks involve repeatedly interpreting ambiguous material; others aim to modify which stimuli attract attention. These procedures differ from conventional advice to think more positively.
In a 2020 systematic review and network meta-analysis, Liviu Fodor and colleagues examined 85 randomized trials of cognitive bias modification. Interpretation training showed a small symptom benefit over sham training in anxiety studies. Other findings were less dependable, and the authors highlighted substantial variation across studies and methodological weaknesses. Evidence for depression was insufficient to support a clear conclusion.
These limitations matter when considering commercially available training programs. A product may use terminology drawn from legitimate research without reproducing the intervention, comparison conditions or clinical support provided in studies. Promises of a guaranteed neurological change should be regarded with particular caution.
Cognitive behavioral therapy, commonly called CBT, is a different and more comprehensive treatment approach. The 2022 NICE depression guideline includes CBT among several evidence-based options selected according to individual needs and preferences.
Therapy may involve examining interpretations, changing behavior, addressing avoidance and developing strategies for recurring difficulties. Although some ideas overlap with cognitive bias research, experimental bias training is not interchangeable with a complete course of CBT.
A clinician can help assess whether a psychological treatment, medication, practical intervention or another form of care is appropriate. The availability of a novel training program is not itself a reason to discontinue existing treatment.
When To Seek Help And When To Trust Your Concerns
Some situations require action rather than reconsideration of your interpretation. Evidence of abuse, unsafe working conditions, escalating health problems or financial exploitation should be addressed through appropriate channels. Psychological concepts must not be used to persuade somebody to disregard a credible concern.
If a pattern of worry, low mood or repetitive checking is increasingly restricting your activities, however, professional assessment may be beneficial. Describe examples of what happens and how it affects your functioning rather than trying to arrive at a clinical explanation beforehand.
If you experience immediate danger or an inability to remain safe, seek local emergency assistance. Persistent or concerning symptoms warrant appropriate care even if you cannot identify a specific cognitive bias.
Research into cognitive biases provides a framework for asking better questions about what information we notice, how we interpret uncertainty and what our memory makes available. Its value lies in improving the accuracy and usefulness of our judgments, not forcing optimism or assigning blame for distress. An informed response makes room for actual evidence, practical circumstances and professional support when necessary.
Sleep and other physical conditions can also affect how easily you sustain attention and manage demanding situations. Our article on chronic stress and the brain explains why persistent cognitive difficulties deserve a broader assessment than the assumption that someone is simply thinking incorrectly.
