Cognitive immunization
{{merge to|Self-deception|date=May 2025}}
Cognitive immunization refers to the psychological process of rejecting information that is misaligned with one's existing beliefs.{{Cite journal |last=Würtz |first=Felix |last2=Kube |first2=Tobias |last3=Woud |first3=Marcella |last4=Blackwell |first4=Simon |last5=Margraf |first5=Jürgen |date=2021-12-01 |title=The interplay of interpretation biases and cognitive immunization in depression |url=https://osf.io/6bx4v/ |journal=Open Science Framework |language=en}} Instead of updating beliefs when presented with new information, those who exhibit cognitive immunization will instead preserve their assumptions about themselves and the world.
Cognitive immunization is primarily studied in clinical psychology, often in conjunction with major depressive disorder and generalized anxiety disorder.{{Cite journal |last=Kube |first=Tobias |last2=Glombiewski |first2=Julia Anna |last3=Gall |first3=Jeremias |last4=Touissant |first4=Leslie |last5=Gärtner |first5=Thomas |last6=Rief |first6=Winfried |date=2019-05-01 |title=How to modify persisting negative expectations in major depression?

Clinical relevance
Aaron T. Beck, a pioneer in cognitive behavioural therapy, first theorized that depression is rooted in negative beliefs about oneself.{{Cite web |title=The Negative Core Beliefs Inventory: Development and Psychometric Properties {{!}} Springer Publishing |url=https://connect.springerpub.com/highwire_display/entity_view/node/87518/full |access-date=2025-04-29 |website=connect.springerpub.com |language=en}} Many cognitive theories, as a result, propose that biased negative beliefs are a mechanism that perpetuate depression.{{Cite journal |last=Uwajeh |first=K. |last2=Egbuchulem |first2=K.

Studies have since found that those with major depressive disorder, or similar disordered thinking patterns, are more likely to use cognitive immunization to disregard positive information in favor of maintaining their negative beliefs. This can result in ongoing negative beliefs about oneself and sustained depressive episodes.{{Cite journal |last=Kube |first=Tobias |last2=Glombiewski |first2=Julia Anna |date=2021-06-01 |title=How Depressive Symptoms Hinder Positive Information Processing: An Experimental Study on the Interplay of Cognitive Immunisation and Negative Mood in the Context of Expectation Adjustment |url=https://link.springer.com/article/10.1007/s10608-020-10191-4 |journal=Cognitive Therapy and Research |language=en |volume=45 |issue=3 |pages=517–528 |doi=10.1007/s10608-020-10191-4 |issn=1573-2819|doi-access=free }}
The relationship between expectations of oneself and cognitive immunization have also been studied in the context of persisting mental disorders.{{Cite journal |last=Rief |first=Winfried |last2=Joormann |first2=Jutta |date=2019-03-29 |title=Revisiting the Cognitive Model of Depression: The Role of Expectations |url=https://cpe.psychopen.eu/index.php/cpe/article/view/2373 |journal=Clinical Psychology in Europe |language=en |volume=1 |issue=1 |pages=1–19 |doi=10.32872/cpe.v1i1.32605 |issn=2625-3410}} It has been found that those with mental health disorders are more likely to use cognitive immunization to reject positive expectations of themselves than those without mental health disorders.{{Cite journal |last=Ewen |first=Anne-Catherine I. |last2=Rief |first2=Winfried |last3=Wilhelm |first3=Marcel |date=2022-12-08 |title=Exploring the path of persisting dysfunctional expectations—Development of the immunization scale IMS |url=https://www.frontiersin.org/journals/psychology/articles/10.3389/fpsyg.2022.1033078/full |journal=Frontiers in Psychology |language=English |volume=13 |issn=1664-1078}} This indicates that the inhibition of cognitive immunization is an important mechanism to target in therapeutic intervention.{{Cite journal |last=Kube |first=Tobias |last2=Rief |first2=Winfried |last3=Gollwitzer |first3=Mario |last4=Gärtner |first4=Thomas |last5=Glombiewski |first5=Julia Anna |date=July 2019 |title=Why dysfunctional expectations in depression persist – Results from two experimental studies investigating cognitive immunization |url=https://www.cambridge.org/core/journals/psychological-medicine/article/abs/why-dysfunctional-expectations-in-depression-persist-results-from-two-experimental-studies-investigating-cognitive-immunization/478F2E774C50E428ACDAE02BA32A591C |journal=Psychological Medicine |language=en |volume=49 |issue=9 |pages=1532–1544 |doi=10.1017/S0033291718002106 |issn=0033-2917|url-access=subscription }}
In this context, Expectation-Focused Psychological Interventions (EFPI),{{Cite journal |last=Kube |first=Tobias |last2=Glombiewski |first2=Julia Anna |last3=Rief |first3=Winfried |date=2018 |title=Using Different Expectation Mechanisms to Optimize Treatment of Patients With Medical Conditions: A Systematic Review |url=https://pubmed.ncbi.nlm.nih.gov/29697530 |journal=Psychosomatic Medicine |volume=80 |issue=6 |pages=535–543 |doi=10.1097/PSY.0000000000000596 |issn=1534-7796 |pmid=29697530}} or therapy that tests the credibility of a patient's expectations, can be an impactful tool for those who exhibit cognitive immunization.{{Cite journal |last=Doering |first=Bettina K. |last2=Glombiewski |first2=Julia A. |last3=Rief |first3=Winfried |date=2018 |title=Expectation-Focused Psychotherapy to Improve Clinical Outcomes |url=https://pubmed.ncbi.nlm.nih.gov/29681329 |journal=International Review of Neurobiology |volume=138 |pages=257–270 |doi=10.1016/bs.irn.2018.02.004 |issn=2162-5514 |pmid=29681329}} EFPI allows therapists and practitioners to test the beliefs of those with depression or anxiety and to potentially correct any instances of cognitive immunization.{{Cite journal |last=Vîslă |first=Andreea |first2= |first3= |first4= |last5= |first5= |date=2018-05-04 |title=The relation between outcome expectation, therapeutic alliance, and outcome among depressed patients in group cognitive-behavioral therapy |url=https://www.tandfonline.com/doi/abs/10.1080/10503307.2016.1218089 |journal=Psychotherapy Research |volume=28 |issue=3 |pages=446–456 |doi=10.1080/10503307.2016.1218089 |issn=1050-3307 |pmid=27494662 |via=Google Scholar|url-access=subscription }}
Mechanisms and cognitive models
Cognitive immunization is considered a maladaptive cognitive process that rejects or dismisses expectation-disconfirming information. This phenomenon can be related to the violEx model,{{Cite journal |last=Panitz |first=Christian |last2=Endres |first2=Dominik |last3=Buchholz |first3=Merle |last4=Khosrowtaj |first4=Zahra |last5=Sperl |first5=Matthias F.

According to this model, when an individual rejects novel information in favor of maintaining outdated or biased beliefs, they are cognitively immunizing themselves against disconfirming information.
