Behavioral biases influence financial decision-making by shaping how individuals perceive risk, assess information, and react to market fluctuations. These biases, rooted in cognitive shortcuts or heuristics, allow quick decision-making but can lead to systematic errors. Recognizing these biases is crucial for investors, as they impact portfolio management and financial outcomes.Limited attention bias occurs when individuals focus on salient or easily accessible information while neglecting...

Social Psychology is a complex field—one that investigates how social contexts affect people’s actions, thoughts, and attitudes. It brings the scientific method into our everyday lives by addressing questions relevant to interactions amongst individuals near and far or even over the internet. For example, the video about ostracism details an approach to induce feelings of exclusion without direct face-to-face contact. These videos are meant to show the wide reactionary nature of human beings,...

Confirmation Biases

The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias? Another...

Source: Laboratories of Gary Lewandowski, Dave Strohmetz, and Natalie Ciarocco—Monmouth University As the Department Chair of Psychology at Monmouth University, I teach primarily upper level undergraduate students who are interested in Experimental Methods. These classes don’t have the same inherent appeal to students. This JoVE Psychology collection will help students vicariously watch the experiments being performed from start to finish, allowing them to gain exposure to over a dozen topics...

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University As an Assistant Professor of Psychology and Cognitive Science at Johns Hopkins University, I teach Introduction to Cognitive Psychology. This large class primarily consists of freshman and sophomores majoring in related fields, like Psychology, Neuroscience, or Cognitive Science. One of the challenges I face in the classroom is teaching students to appreciate how data are obtained in the process of performing experiments.
FAQs
Mental shortcuts help people handle complex or incomplete information by relying on prior beliefs, selective attention, or emotional responses. These processes can make judgment more efficient, but they may also produce consistent patterns in how information is perceived, events are interpreted, or other people are evaluated. The resulting errors are systematic rather than random, making them suitable for psychological study.
Confirmation bias concerns the interpretation or selection of information in ways related to existing beliefs. Availability bias reflects the influence of information that is especially accessible when people judge events or risks. Implicit bias concerns influences on evaluation that may operate without deliberate awareness. These examples differ in emphasis, but each can affect judgment in predictable ways.
Prior beliefs can shape how people interpret new information, while emotional responses can influence evaluations of events or other people. Selective attention affects which parts of complex or incomplete information receive focus. Because these influences operate during perception and interpretation, the same situation may lead to different judgments depending on the information or reactions that become most prominent.
Bias can influence several stages of thinking, from noticing information to interpreting events and evaluating conclusions. In memory, it may shape how information is recalled or understood; in social judgment, it may affect evaluations of others; and in risk assessment, it may alter how possible outcomes are considered. Psychology examines these effects as recurring patterns of judgment.
Researchers investigate bias through experiments, surveys, and behavioral measures. Experiments can examine how different information or situations influence judgment, surveys can assess reported perceptions and evaluations, and behavioral measures can capture patterns in decisions or responses. Using these approaches allows psychologists to examine how bias appears in specific tasks and to compare its effects across areas of judgment.
Understanding bias is relevant wherever people interpret information or evaluate others, including education, healthcare, organizations, and research. In these settings, knowledge of systematic judgment patterns can support more careful decision-making. The topic also helps explain why judgments may be influenced by selective attention, prior beliefs, or emotional responses rather than by all available information.
Studies can show how people perceive information, interpret events, assess risks, remember material, or evaluate other individuals. They may also identify predictable deviations from objective reasoning and clarify whether a pattern appears in reported judgments, experimental responses, or observed behavior. These outcomes connect laboratory findings with broader questions about decision-making in psychology and applied contexts.
