Bias01:22

Bias

4.3K
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...

Relative Risk01:12

Relative Risk

191
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

133
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Framing Effects03:26

Framing Effects

7.4K
Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Self-Discrepancy Theory02:45

Self-Discrepancy Theory

18.3K
One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

In- and Out-Groups01:31

In- and Out-Groups

39.1K
People all belong to a gender, race, age, and social economic group. These groups provide a powerful source of our identity and self-esteem (Tajfel & Turner, 1979) and serve as our in-groups. An in-group is a group that we identify with or see ourselves as belonging to.

Summary

Economic inequality increases individual risk-taking behavior. Reducing inequality among victims lowers their propensity for risk, supporting risk-sensitivity theory.

Area of Science:

  • Psychology
  • Behavioral Economics
  • Social Science

Background:

  • Societal economic inequality is linked to increased risk-taking.
  • Individual-level effects of economic inequality on risk-taking remain under-investigated.
  • Risk-sensitivity theory posits increased risk-taking when current state falls short of desired state.

Purpose of the Study:

  • To investigate the direct impact of imposed economic inequality on individual risk-taking.
  • To test predictions of risk-sensitivity theory at the individual level.
  • To examine if mitigating inequality affects risk-taking behavior.

Main Methods:

  • Two experiments were conducted to examine the effects of imposed economic inequality.
  • Experiment 1 compared risk-taking between inequality victims, beneficiaries, and a control group.
  • Experiment 2 assessed the impact of ameliorating inequality on victims' risk-taking.

Main Results:

  • Victims of economic inequality consistently demonstrated higher risk-taking than beneficiaries and controls.
  • Reducing inequality for victims led to a significant decrease in their risk-taking.
  • Findings support the hypothesis that disparity drives increased risk-taking.

Conclusions:

  • Imposed economic inequality directly elevates individual risk-taking.
  • Risk-sensitivity theory is supported by these findings.
  • Policies aimed at reducing economic inequality may decrease societal risk-taking.
