The outcomes of motivated reasoning derive from a bias set of cognitive processes that is strategies for accessing, constructing and evaluating beliefs. The motivation to be accurate, enhances the use of those reasoning processes that are considered most appropriate.
Whereas the motivation to arrive at particular conclusions and Hans's use of those that are considered most likely to yield the desired conclusion. An example of motivated reasoning may be seen in the psychological mechanisms. People commonly use to preserve a favorable identity of themselves. In order to maintain positive regard for themselves, people, unconsciously discounts, unflattering information that contradicts their self-image or is otherwise troubling to them.
The same can be seen in whole populations of people where a nation may selectively construct its history, emitting unfavorable elements that are otherwise widely considered historical facts. The common feature of all motivated reasoning is that the outcome is predetermined. And thus the process of reasoning is essentially just a process of searching for evidence and reasons to support the predetermined outcome, which is called rationalization.
This can be seen as an inversion of the normal conception of objective reasoning, where all relevant evidence is gathered, synthesize and thought through to create conclusions with motivated reasoning. However, the outcome is predetermined and the process simply used to present a rational argument to others in one cell.
Social science research suggests that reasoning away contradictions is psychologically easier than revising our feelings. In this sense, emotions are shown to color. How facts are perceived feelings come first to define preconceptions and evidence is used mostly in service of those preconceptions evidence that supports what is already believed is accepted.
That which contradicts it is excluded in various ways.
