Motivation Effect on Reasoning: Motivation may influence reasoning through the use of biased cognitive processes for accessing, constructing, and evaluating beliefs.
Accuracy Goals: Increases use of appropriate beliefs and strategies that enhance reasoning accuracy.
Directional Goals: Enhance use of beliefs and strategies likely to lead to desired conclusions.

Research on Motivated Reasoning: People exhibit a strong tendency to draw conclusions they desire, which is influenced by their ability to rationalize these conclusions through justifications.
Controversial History: The role of motives in reasoning has been historically debated in social psychology:
- Erdelyi (1974): Proposed that motives affect perceptions.
- Festinger (1957): Attitudes can be influenced by motivation.
- Heider (1958): Attributions are also shaped by motives.
Criticism of Motivational Views: 1970s criticisms claimed that all evidence of motivated reasoning could be reinterpreted as cognitive processes without motivational components (Miller & Ross, 1975; Nisbett & Ross, 1980).

Motivation affects cognitive processes that are used to arrive at conclusions and is significant in context-specific reasoning tasks:
- Cognitive Microprocesses: Cognitive processes can be vehicles for directing reasoning under motivational influence.
- Accuracy Goals vs. Directional Goals: There is a critical distinction between these two types of goals, which influence the way information is processed and evaluated.

Cognitive Effort: High motivation for accuracy increases cognitive effort, careful attention, and deeper processing of relevant information, akin to Simon's (1957) satisficing theory.
- Cognitive effort involves weighing search strategies for utility versus costs (Stigler, 1961).
Empirical Evidence:
- McAllister, Mitchell, and Beach (1979): Motivated participants adopt more complex and time-consuming decision-making strategies.
- Kruglanski and Freund (1983): Accuracy-motivated individuals demonstrate reduced cognitive biases (e.g., primacy effect, ethnic stereotypes).
- Tetlock (1983; 1985): Accuracy leads to less susceptibility to attribution errors.
Eliminating Biases: It is possible for deeper processing to occur under accuracy goals, leading to less reliance on biased cognitive shortcuts.

Pupils may lack appropriate reasoning strategies or make poor judgments under motivational influence, since not all biases can be eliminated through motivation alone.
Different Influences: Accidental biases can worsen reasoning under pressure, leading to more complex processing but not necessarily better judgments (Tetlock & Boettger, 1989).

Goals Impacting Reasoning: Driven by the need to validate a specific desired conclusion, individuals may be rational while at the same time constructing justifications that support their wished-for outcome:
- Constructive Justification: Individuals biasedly retrieve memories or beliefs that align with their desired conclusions (Pyszczynski & Greenberg, 1987).

Dissonance Research Evidence: Subjects alter self-characterizations based on motivation.
Kunda and Sanitioso (1989): People overestimate personal traits conducive to success under motivational urges to perceive themselves favorably.
- Note: Past behaviors and characteristics are recalled selectively based on motivational alignments towards current objectives, impacting individuals’ self-perceptions.

Comparative Approaches: Kunda discusses the similarities between cognitive processes in dissonance research and those occurring in motivated reasoning contexts, suggesting that both can lead to biased outcomes.

Mental Health Considerations: Motivated reasoning can drive individuals toward beneficial illusions that promote mental wellbeing.
Risks of Illusions: Motivated reasoning can be dangerous when it outweighs rational decisions, as seen in attitudes towards health and risks.
- E.g., downplaying serious health symptoms due to motivated reasoning can lead to severe consequences.

The interplay of motivation and cognition is complex, leading to varied outcomes in belief construction and cognitive processing.
Need for Further Research: Mechanisms underlying motivated reasoning need more exploration to address biases in reasoning effectively and provide pathways to mitigate their impacts.
