Framing Effects03:26

Framing Effects

7.6K
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...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

218
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,...

Relative Risk01:12

Relative Risk

866
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...

Hazard Ratio01:12

Hazard Ratio

339
The hazard ratio (HR) is a widely used measure in clinical trials to compare the risk of events, such as death or disease recurrence, between two groups over time. It reflects the ratio of hazard rates—the instantaneous risk of the event occurring—between a treatment group and a control group. This measure provides valuable insights into the relative effectiveness of a treatment by assessing how the risk of an event differs between the two groups.
For example, in a clinical trial...

Regression Toward the Mean01:52

Regression Toward the Mean

6.6K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Social Traps01:41

Social Traps

24.9K
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Summary

People value reducing deaths from mass shootings more than from international terrorism. This risk perception holds even when personal beliefs about terrorism threats differ, indicating a consistent public preference.

Area of Science:

  • Social Psychology
  • Risk Analysis
  • Public Policy

Background:

  • Mass shootings and international terrorism are significant public risks with traumatic consequences.
  • Understanding public risk perception and risk-risk tradeoffs is crucial for policy-making.

Purpose of the Study:

  • To investigate risk perceptions and risk-risk tradeoffs between mass shootings and international terrorism.
  • To determine if individuals prioritize reducing one risk over the other and by how much.

Main Methods:

  • An original survey was designed to assess tradeoff rates between deaths from mass shootings and international terrorism.
  • Statistical analysis was used to evaluate risk-risk tradeoff rates, controlling for personal risk beliefs.

Main Results:

  • Respondents consistently assigned a higher value to reducing risks from mass shootings compared to international terrorism.
  • This risk premium for mass shootings remained stable across different personal risk belief levels.

Conclusions:

  • Public risk perception indicates a greater aversion to mass shooting risks than international terrorism risks.
  • Policy preferences may need to account for these differential risk valuations to be effective.
