paragraph_text: Models of belief formation
  
  Psychologists study belief formation and the relationship between beliefs and actions. Three types of models of belief formation and change have been proposed: conditional inference process models, linear models and information processing models.
  
  Conditional inference process models emphasize the role of inference for belief formation. When asked to estimate the likelihood that a statement is true, people allegedly search their memory for information that has implications for the validity of this statement. Once this information has been identified, they estimate the likelihood that the statement would be true if the information were true, and the likelihood that the statement would be true if the information were false. If their estimates for these two probabilities differ, people average them, weighting each by the likelihood that the information is true and false. Thus, information bears directly on beliefs of another, related statement.
  
  Unlike the previous model, linear models take into consideration the possibility of multiple factors influencing belief formation. Using regression procedures, these models predict belief formation on the basis of several different pieces of information, with weights assigned to each piece on the basis of their relative importance.
  
  Information processing models address the fact that the responses people have to belief-relevant information is unlikely to be predicted from the objective basis of the information that they can recall at the time their beliefs are reported. Instead, these responses reflect the number and meaning of the thoughts that people have about the message at the time that they encounter it.
  
  Some influences on people's belief formation include:
  
  However, even educated people, well aware of the process by which beliefs form, still strongly cling to their beliefs, and act on those beliefs even against their own self-interest. In her book Leadership Therapy, Anna Rowley states: "You want your beliefs to change. It's proof that you are keeping your eyes open, living fully, and welcoming everything that the world and people around you can teach you." This view implies that peoples' beliefs may evolve as they gain new experiences.
