Belief perseverance (also known as conceptual conservatism) is maintenance of a belief despite new information that firmly contradicts it.
Since rationality involves conceptual flexibility, belief perseverance is consistent with the view that human beings act at times in an irrational manner. Philosopher F.C.S. Schiller holds that belief perseverance "deserves to rank among the fundamental 'laws' of nature".
In psychology and cognitive science, a schema (pl.: schemata or schemas) describes a pattern of thought or behavior that organizes categories of information and the relationships among them. It can also be described as a mental structure of preconceived ideas, a framework representing some aspect of the world, or a system of organizing and perceiving new information, such as a mental schema or conceptual model. Schemata influence attention and the absorption of new knowledge: people are more likely to notice things that fit into their schema, while re-interpreting contradictions to the schema as exceptions or distorting them to fit. Schemata have a tendency to remain unchanged, even in the face of contradictory information. Schemata can help in understanding the world and the rapidly changing environment. People can organize new perceptions into schemata quickly as most situations do not require complex thought when using schema, since automatic thought is all that is required.
People use schemata to organize current knowledge and provide a framework for future understanding. Examples of schemata include mental models, social schemas, stereotypes, social roles, scripts, worldviews, heuristics, and archetypes. In Piaget's theory of development, children construct a series of schemata, based on the interactions they experience, to help them understand the world.
In social psychology, a stereotype is a generalized belief about a particular category of people. It is an expectation that people might have about every person of a particular group. The type of expectation can vary; it can be, for example, an expectation about the group's personality, preferences, appearance or ability. Stereotypes make information processing easier by allowing the perceiver to rely on previously stored knowledge in place of incoming information. Stereotypes are often faulty, inaccurate, and resistant to new information. Although stereotypes generally have negative implications, they aren't necessarily negative. They may be positive, neutral, or negative. They can be broken down into two categories: explicit stereotypes, which are conscious, and implicit stereotypes, which are subconscious.
Cognitive inertia is the tendency – for a particular orientation in an individual's thinking about a matter, belief, or strategy – to resist change. Clinical and neuroscientific literature often describes it as a lack of motivation to generate cognitive processes needed to attend to a matter or problem.
The physics term "inertia" emphasizes resistance to change in a mode of cognitive processing that has been used for a substantial time. Commonly confused with belief perseverance, cognitive inertia is perseverance in an interpretation of information, not perseverance in the belief itself.
