Confirmation Biases01:31

Confirmation Biases

8.6K
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?

Correspondence Bias01:17

Correspondence Bias

329
Correspondence bias, also referred to as the fundamental attribution error, describes the tendency to attribute another person’s behavior to internal characteristics rather than situational influences. This cognitive bias leads individuals to overlook external factors that may be influencing actions, thereby fostering potentially inaccurate assessments of others’ intentions and dispositions.Empirical Evidence for Correspondence BiasResearch has consistently demonstrated the...

Bias

Bias refers to any tendency that prevents a question from being considered unprejudiced. In research, bias occurs when one outcome or answer is selected or encouraged over others in sampling or testing. Bias can occur during any research phase, including study design, data collection, analysis, and publication.
In statistics, a sampling bias is created when a sample is collected from a population, and some members of the population are not as likely to be chosen as others (remember, each member...

Cause and Effect

12.7K
While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?

Motivational Bias01:25

Motivational Bias

478
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,...

First Impression01:09

First Impression

363
First impressions play a crucial role in social perception, shaping how individuals assess others in professional, academic, and interpersonal contexts. Psychological research highlights the significance of cognitive biases, such as the primacy and recency effects, which influence how people interpret and recall information.The Primacy Effect and Cognitive AnchoringThe primacy effect describes the tendency for initial information to impact judgment disproportionately. When individuals encounter...

Summary

Psychological scientists often test non-absolute hypotheses, using confirmation strategies appropriately. The study finds falsification is less applicable for common research goals, challenging traditional scientific method views.

Area of Science:

  • Psychology
  • Scientific Methodology

Background:

  • The confirmatory approach to hypothesis testing is often criticized.
  • Understanding the prevalence and justification of different hypothesis-testing strategies in psychological science is crucial.

Purpose of the Study:

  • To investigate the incidence and appropriateness of confirmatory hypothesis testing in psychological research.
  • To examine the relationship between research goals and the strategies employed by psychological scientists.

Main Methods:

  • A survey was administered to psychological scientists regarding their research goals and strategies.
  • Analysis focused on reported goals (e.g., testing non-absolute vs. universal hypotheses) and preferred testing strategies (confirmation vs. disconfirmation).

Main Results:

  • The most common research goal is testing non-absolute hypotheses (i.e., a relation exists under some conditions).
  • Confirmation strategies are predominantly used for non-absolute hypotheses, while disconfirmation is used for absolute hypotheses.
  • Confirmatory search is prevalent and associated with testing non-absolute hypotheses.

Conclusions:

  • A confirmatory approach is the normatively correct method for testing the non-absolute hypotheses that initiate most psychological studies.
  • Popper's falsification strategy is often inappropriate given the rarity of universal hypothesis testing in the field.
