The Replication Crisis in Biomedicine

The replication crisis (also called the replicability crisis and the reproducibility crisis) is an ongoing methodological crisis in which it has been found that the results of many scientific studies are difficult or impossible to reproduce.

What is the meaning of replication crisis?

The replication crisis, also known as the replicability crisis or the reproducibility crisis, refers to the growing belief that the results of many scientific studies cannot be reproduced and are thus likely to be wrong.

What is the replication crisis and what are some causes?

The replication crisis in psychology, as it is often called, started around 2010, when a paper using completely accepted experimental methods was published purporting to find evidence that people were capable of perceiving the future, which is impossible.

What is the main solution to the replication crisis?

Open Research is the answer

The solution to the scientific reproducibility crisis is to move towards Open Research the idea that scientific knowledge of all kinds should be openly shared as early as it is practical in the discovery process.

When did the replication crisis start?

So what is going on and is it really a crisis? The dialogue around replication ignited in 2015 when Brian Nosek’s lab reported that after replicating 100 studies from three psychology journals, researchers were unable to reproduce a large portion of findings.

Why is the replication crisis a problem?

Because the reproducibility of empirical results is an essential part of the scientific method, such failures undermine the credibility of theories building on them and potentially call into question substantial parts of scientific knowledge.

What have we learned from the replication crisis?

The replication crisis has led a few researchers to ask: Is there a way to guess if a paper will replicate? A growing body of research has found that guessing which papers will hold up and which won’t is often just a matter of looking at the same simple, straightforward factors.

Why replication is important in psychology?

When studies are replicated and achieve the same or similar results as the original study, it gives greater validity to the findings. If a researcher can replicate a study’s results, it means that it is more likely that those results can be generalized to the larger population.

What is the replication crisis in psychology Google Scholar?

Psychological science is in the midst of what has been referred to as a replication crisis. The realization that many individual findings do not replicate in new studies has led to questioning the scientific method and the integrity of psychological science.

What are the two types of replication?

Types of Replication:

Snapshot replication sends the entire data set to the subscriber. Transactional replication only sends modifications to the data. Merge replication items are modified at both the publisher and subscribers.

How can the replication crisis be improved in psychology?

Which practices can fix the replication crisis? Psychologists have developed an array of strategies to ensure that future findings have greater credibility. These include conducting more replications of emerging findings, relying on larger sample sizes, and leveraging thoroughly tested measures.

Is psychology suffering from a replication crisis?

Psychology has recently been viewed as facing a replication crisis because efforts to replicate past study findings frequently do not show the same result. Often, the first study showed a statistically significant result but the replication does not.

What is conceptual replication in psychology?

But conceptual replication also has a very important role to play in psychological science. What is conceptual replication? It’s when instead of replicating the exact same experiment in exactly the same way, we test the experiment’s underlying hypothesis using different methods.

What types of research has been replicated?

Identical or literal studies are considered exact replications. Type 2. Virtual, operational, direct, and retest are terms used to indicate that a study is closely replicated. This strategies aproximate the original research design.

What is the replication crisis quizlet?

The replication crisis or replicability crisis or reproducibility crisis is an ongoing (2019) methodological crisis in which it has been found that many scientific studies are difficult or impossible to replicate or reproduce. The replication crisis affects the social and life sciences most severely.

Why is replication important in research?

It is very important that research can be replicated, because it means that other researchers can test the findings of the research. Replicability keeps researchers honest and can give readers confidence in research.

What is the crisis in social psychology?

The concept of ‘crisis of relevance’ refers to the social responsiveness of social psychology. Many people felt dissatisfaction with social psychology in relation to their own lives and the social world around them (Armistead, 1974).

What is a replication plus extension?

Replication-plus-extension. A replication study in which researchers replicate their original study but add variables or conditions that test additional questions.

Why do researchers try to replicate a result especially a surprising one?

Why do researchers try to replicate a result especially a surprising one? Replication is vital to science. It helps make science a self-correcting system. Any time a result is surprising, researchers will try to replicate it, to see if the phenomenon is dependable or just a fluke (a one-time occurrence).

Where does replication occur?

DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes. Regardless of where DNA replication occurs, the basic process is the same. The structure of DNA lends itself easily to DNA replication.

What are two criticisms of social psychology?

Much research in social psychology has consisted of laboratory experiments on social behaviour, but this approach has been criticized in recent years as being too stultifying, artificial, and unrealistic. Much of the conceptual background of research in social psychology derives from other fields of psychology.

What is the role of replication in psychological research quizlet?

What is the role of replication in psychological research? Replication provides scientifically verified approaches to treating mental illness.

What is the meaning of replicability in English?

: capable of replication replicable experimental results.

What is the disadvantage of replication?


More storage space is needed as storing the replicas of same data at different sites consumes more space. Data Replication becomes expensive when the replicas at all different sites need to be updated. Maintaining Data consistency at all different sites involves complex measures.

What are the three replication strategies?

Data Replication Strategies
  • Strategy 1: Log-Based Data Replication.
  • Strategy 2: Full Table Data Replication.
  • Strategy 3: Key-Based Incremental Data Replication.

What are the advantages of replication?

By spreading your data across multiple machines, you can ensure that your application’s data continues to be available even in the event of a hardware failure on any given machine in the replication group. Improve read performance. By using replication you can spread data reads across multiple machines on your network.

Who coined replication crisis?

Comment: What has been coined the replication crisis exploded into psychology in 2015 when a report by Brian Nosek et al. found that, after replicating 100 studies from three psychology journals, researchers were unable to reproduce a large portion of findings (Open Science Collaboration, 2015).

Does ego depletion exist?

While multiple studies provided support for the ego depletion effect, there is currently no direct measure of ego depletion, and studies mainly observe it by measuring how long people persist at a second task after performing a self-control task (the depleting task).

What is file drawer problem?

The file drawer problem, or publication bias, which was first proposed by Rosenthal in 1979 [1], refers to a trend or culture of publishing selected results instead of the entire outcome that, in turn, misrepresents the real findings.

Is psychology a BS or BA?

The B.A., or Bachelor of Arts, in Psychology is meant to prepare students for professional careers related to psychology. The B.A. often involves more elective requirements than the typical B.S. (Bachelor of Science), allowing students to focus on areas of study beyond general psychology.

What is independent replication?

Independent replicates

Each particular replicate is subject to random factors, which may increase or decrease its value. Each random factor affects individual replicates, and no random factor affects the replicates as a group.

How do you know if a study has been replicated?

The most direct method to assess replicability is to perform a study following the original methods of a previous study and to compare the new results to the original ones.

In which study the conditions of a system or process are replicated?

A replication study involves repeating a study using the same methods but with different subjects and experimenters.

What is the definition of replication psychology quizlet?

Replication. The process of repeating research to determine the extent to which findings generalize across time and across situations.

What would a researcher attempting to conduct a conceptual replication of a past study do?

Terms in this set (5) What would a researcher attempting to conduct a conceptual replication of a past study do? The researcher would read the published article about the original research and create new procedures and materials that test the same hypothesis in a somewhat different way.

What is a survey psychology quizlet?

Terms in this set (20)

survey. research technique for acquiring data. target population. total group to be studied or described and from whom samples may be drawn.

What is the purpose of replication?

Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell. The replication process relies on the fact that each strand of DNA can serve as a template for duplication.

What is a successful replication?

Specifically, a replication attempt is considered to be successful when both the original and replication study report a significant p-value, in addition to both studies having an effect in the same direction (e.g. [30,36]).
