Replication Crisis

The Replication Crisis (pronounced: reh-pli-kay-shun kri-sis) is a methodological crisis that has been ongoing in various scientific disciplines since the early 2010s. It is a significant issue in the field of science and research, particularly in psychology, medicine, and social sciences.

Etymology

The term "Replication Crisis" is derived from the word 'replicate' which means to duplicate or reproduce, and 'crisis' which refers to a time of intense difficulty or danger. In this context, it refers to the difficulty in reproducing the results of previous studies, leading to a crisis in the credibility of certain scientific fields.

Definition

The Replication Crisis refers to the growing awareness that a proportion of scientific studies are not reproducible, undermining the reliability of published research. This crisis is most severe in psychology and biomedical research where many studies have been found to be unreproducible.

Causes

The causes of the Replication Crisis are multifaceted and include publication bias, statistical errors, and methodological flaws. Other contributing factors include the pressure to publish, selective reporting of results, and lack of transparency in research methods.

Impact

The Replication Crisis has significant implications for the scientific community. It undermines the trust in scientific research and can lead to wastage of resources on studies that are not reproducible. It also has implications for policy decisions that are based on scientific research.

Related Terms

  • Publication Bias: The tendency for researchers and editors to handle the reporting of experimental results that are positive (i.e., showing a significant finding) differently from results that are negative (i.e., supporting the null hypothesis) or inconclusive, leading to a bias in the overall published literature.
  • Statistical Errors: Errors or mistakes made in the collection, analysis, interpretation, presentation, and organization of data.
  • Methodological Flaws: Mistakes or errors in the design or execution of scientific experiments or studies.
