What is replication failure in psychology?
The replication crisis in psychology refers to concerns about the credibility of findings in psychological science. … For this reason, many scientists question the accuracy of published findings and now call for increased scrutiny of research practices in psychology.
Why is replicability hard in psychology?
So why are psychology results so difficult to replicate? Writing for The Guardian, John Ioannidis suggested that there are a number of reasons why this might happen, including competition for research funds and the powerful pressure to obtain significant results.
What are at least three reasons that a replication attempt might fail?

What does replication involve in psychology?
Replication involves the process of repeating a study using the same methods, different subjects, and different experimenters. It can also involve applying the theory to new situations in an attempt to determine the generalizability to different age groups, locations, races, or cultures.
