Summary
Motivation influences reasoning by biasing cognitive processes. People use strategies to reach desired conclusions, but this is limited by their ability to create justifications for those beliefs.
Area of Science:
- Cognitive Psychology
- Social Psychology
Background:
- Motivation significantly impacts cognitive processes.
- Reasoning can be influenced by the desire to reach specific conclusions or the need for accuracy.
Purpose of the Study:
- To explore how motivation affects reasoning through biased cognitive strategies.
- To explain the mechanisms underlying motivated reasoning.
Main Methods:
- Review of existing research on motivated reasoning.
- Analysis of cognitive strategies for belief access, construction, and evaluation.
Main Results:
- Motivation to be accurate promotes appropriate belief and strategy use.
- Motivation to reach desired conclusions favors strategies likely to yield them.
- The ability to justify conclusions constrains motivated reasoning outcomes.
Conclusions:
- Motivated reasoning is a key factor in understanding belief formation.
- Cognitive biases in accessing, constructing, and evaluating beliefs are central to motivated reasoning.
- The interplay between desired conclusions and justification ability shapes reasoning processes.

Inductive Reasoning
Inductive reasoning is a form of logical thinking that uses related observations to arrive at a general conclusion. It is uncertain and operates in degrees to which the conclusions are credible. As such, inductive arguments can be weak or strong, rather than valid or invalid, and conclusions can be used to formulate testable, falsifiable hypotheses.Inductive reasoning is common in descriptive science. A life scientist makes observations and records them. This data can be qualitative or...
Reason and Intuition
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the brain can only use...
Fundamental Attribution Error
According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is called the fundamental attribution...
Reasoning
Reasoning is the action of thinking about something in a logical, sensible way. It is integral to problem-solving, decision-making, and critical thinking. Reasoning can be inductive or deductive. Reasoning involves transforming information into conclusions, which is essential for problem-solving, decision-making, and critical thinking.
Inductive reasoning involves deriving generalizations from specific observations. This type of reasoning helps form beliefs about the world. For example,...

Drive-Reduction Theory: Push Theory of Motivation
Clark Hull's drive-reduction theory, introduced in the 1940s and 1950s and often termed the "push theory" of motivation, provides a framework for understanding how biological and learned drives influence behavior. Hull suggested that motivation originates from the need to alleviate physiological tension caused by unmet biological necessities. The theory proposes that when a basic need, such as hunger or sleep, goes unfulfilled, it creates an internal imbalance. This imbalance, or drive, pushes...
Motivational Bias
Cognitive bias results from limitations in thinking and information processing, leading to systematic errors in judgment. Conversely, motivational bias stems from personal desires or emotions, causing distortions in perception to align with self-interest. Motivational bias influences how individuals perceive and attribute causes to events, often shaped by personal needs, goals, and self-esteem preservation. This bias can distort judgment, leading to inaccurate assessments of success, failure,...
