Scientific Nature of Social Psychology01:30

Scientific Nature of Social Psychology

786
Social psychology is a scientific discipline dedicated to understanding how individuals think, feel, and behave in social contexts. Unlike common sense, which relies on anecdotal experiences and intuition, social psychology employs systematic research and empirical methods to ensure objectivity and reliability. This distinction is fundamental in distinguishing scientifically supported findings from mere speculation.Four fundamental scientific values guide a structured approach to research in...

Empirical Method to Interpret Standard Deviation01:09

Empirical Method to Interpret Standard Deviation

10.7K
The empirical rule, also known as the three-sigma rule, allows a statistician to interpret the standard deviation in a normally distributed dataset. The rule states that 68% of the data lies within one standard deviation from the mean, 95% lies within two standard deviations from the mean, and 99.7% lies within three standard deviations from the mean. Additionally, this rule is also called the 68-95-99.7 rule.
This rule is used widely in statistics to calculate the proportion of data values...

Regression Toward the Mean01:52

Regression Toward the Mean

7.3K
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...

Deviation from Ideal Behaviour01:23

Deviation from Ideal Behaviour

137
Real gases do not perfectly obey the ideal gas laws, especially at high pressures and low temperatures or when they are about to condense to a liquid. These deviations occur due to intermolecular forces between gas molecules. Repulsive forces aid expansion and are significant when molecules are very close together, typically at high pressure. Attractive forces assist compression and have a longer range, being effective over several molecular diameters. They become significant when molecules are...

Introduction to Psychological Disorders

1.7K
Abnormal behavior, often referred to as mental illness, results from changes in brain function that influence thought patterns, behaviors, and social interactions. Psychologists and psychiatrists typically assess abnormal behavior using three primary criteria: deviance, maladaptation, and personal distress, particularly when these traits persist over long periods.
Deviant Behavior
Deviance in behavior refers to actions or thought patterns that significantly diverge from societal norms or...

Introduction to Normal Distributions01:29

Introduction to Normal Distributions

219
Standardized test scores often follow a symmetric distribution that can be modeled with the normal distribution, a fundamental concept in statistics. This distribution is particularly useful for interpreting test performance fairly across populations, as it provides a mathematical framework for understanding variability and central tendency in large datasets.From Histogram to Frequency DistributionRaw test data are often displayed using histograms, where the height of each bar represents the...

Summary
This summary is machine-generated.

Normalization of deviance, a concept from the Challenger disaster, explains how healthcare workers become desensitized to unsafe practices, leading to patient harm. Understanding this phenomenon is crucial for preventing medical errors and improving patient safety.

Area of Science:

  • Healthcare safety
  • Organizational behavior
  • Sociology of risk

Background:

  • Normalization of deviance, coined by Diane Vaughan, describes how repeated tolerance of deviations leads to insensitivity to risk.
  • This phenomenon was identified as a key factor in the Challenger disaster due to NASA's handling of O-ring flaws.
  • Healthcare settings exhibit similar patterns where deviations from evidence-based practice can occur.

Purpose of the Study:

  • To introduce the concept of normalization of deviance to the healthcare field.
  • To explore the impact of this concept on patient harm within clinical practice.
  • To identify strategies for preventing normalization of deviance in healthcare, drawing from other high-risk industries.

Main Methods:

  • Conceptual analysis of Diane Vaughan's work on normalization of deviance.
  • Application of the concept to clinical practices such as procedural time-outs, alarm management, and infection control.
  • Review of strategies used in other high-risk industries to mitigate the effects of normalization of deviance.

Main Results:

  • Deviations in healthcare, like failing to perform time-outs or breaching infection control, are often driven by factors such as time, cost, and peer pressure, not intent to harm.
  • Healthcare workers may justify these deviations, similar to operators in other industries.
  • The concept of normalization of deviance is underutilized in healthcare, despite its potential to explain patient harm.

Conclusions:

  • Normalization of deviance poses a significant, yet often unrecognized, threat to patient safety in healthcare.
  • Urgent exploration of this concept's impact on patient harm is necessary.
  • Adopting preventative strategies from other high-risk industries can help mitigate the risks associated with normalization of deviance in healthcare.
