Stereotypes, Prejudice, and Discrimination02:55

Stereotypes, Prejudice, and Discrimination

92.4K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Confirmation Biases

7.4K
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?

Bias01:22

Bias

6.3K
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...

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Halo Effect01:27

Halo Effect

44
The halo effect is a cognitive bias in which an individual's overall impression influences judgments about their specific traits. This psychological phenomenon leads people to associate positive characteristics with those they perceive as generally good and negative characteristics with those they view as bad. This effect is particularly influential in social perception, professional evaluations, and decision-making processes.The Psychological Basis of the Halo EffectThe halo effect is rooted...

Motivational Bias01:25

Motivational Bias

134
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,...

Resumen

Los métodos de inferencia causal pueden analizar datos policiales defectuosos para revelar ideas precisas. Este enfoque ayuda a superar las limitaciones en la recopilación de datos para comprender mejor las prácticas policiales.

Área de la Ciencia:

  • Criminología
  • Las estadísticas
  • Políticas públicas

Sus antecedentes:

  • Los datos policiales a menudo contienen inexactitudes y sesgos.
  • Los métodos de análisis tradicionales luchan con las imperfecciones de los datos.
  • La comprensión de la policía requiere técnicas analíticas sólidas.

Objetivo del estudio:

  • Demostrar la utilidad de la inferencia causal en el análisis de datos policiales imperfectos.
  • Proporcionar un marco para abordar las limitaciones de datos en la investigación de justicia penal.

Principales métodos:

  • Aplicación de técnicas de inferencia causal.
  • Modelado estadístico para dar cuenta de los sesgos de los datos.
  • Análisis de conjuntos de datos policiales simulados y reales.
