Belief-based and preference-based models provide key frameworks for understanding decision-making in uncertain environments. These models explain how individuals and organizations make choices by balancing probabilities, personal values, and priorities.Belief-based models emphasize how people form expectations about uncertain outcomes. Perceived probabilities, past experiences, and new information influence decision-making under this model. People often use logical reasoning or heuristics to...

Cognitive Dissonance

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...

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? Another...

Source: Laboratories of Gary Lewandowski, Dave Strohmetz, and Natalie Ciarocco—Monmouth University Clinical research focuses on the efficacy of treatments for addressing disorders and illnesses. A challenge with this type of research is that participants often have pre-existing beliefs about the treatment, particularly expectations that the treatment will work. Though it has been practiced around the world for centuries, yoga is a relatively recent fitness craze in the United States with a...

FAQs
Existing assumptions influence which parts of new information receive attention and how that information is interpreted. When corrective evidence conflicts with an initial conclusion, people may emphasize details that remain compatible with what they already believe. This selective interpretation can preserve the original judgment even when its supporting evidence has been shown to be unreliable.
People may construct explanations that continue to make the initial conclusion seem reasonable. Rather than simply removing the belief when its evidence is discredited, they organize available details around the earlier interpretation. This explanatory process helps preserve coherence, but it can also prevent corrective information from producing a substantial change in judgment.
Ordinary belief revision involves changing a judgment when important supporting information no longer appears reliable. Belief perseverance describes a different outcome: the original conclusion remains influential despite discrediting evidence. The contrast is useful in psychology because it focuses attention on how interpretation, attention, and explanation can interfere with updating rather than on belief formation alone.
Corrective evidence tests whether a judgment changes after participants learn that its original support is invalid. Researchers first establish a conclusion or interpretation, then present information that discredits the basis for it. The remaining strength of the judgment reveals how strongly the initial conclusion persists after its evidential foundation has been removed.
A typical study gives participants information that supports an initial judgment, provides feedback or other evidence that challenges or discredits that support, and then measures the participants’ later judgments. Comparing the later responses with the original conclusions allows researchers to assess whether corrective information changed the interpretation or whether the initial belief continued to guide responses.
Researchers measure whether participants revise their judgments after receiving corrective information. The central outcome is the degree to which an initial conclusion remains present after its supporting evidence has been discredited. These judgment measures help identify persistence and show how effectively participants incorporate feedback into their subsequent interpretations.
The phenomenon helps explain why misinformation can remain influential after correction and why people may resist revising decisions or interpretations. In psychology, this has relevance to interpersonal conflict, clinical and educational judgments, and scientific interpretations. Studying the process clarifies how unsupported conclusions can continue shaping reasoning after the information that prompted them is no longer credible.
