An investigation of replication rates in psychology in 2012 indicated higher success rates of replication in replication studies when there was author overlap with the original authors of a study [224] (91.7% successful replication rates in studies with author overlap compared to 64.6% successful replication rates without author overlap).
Even well-written papers may not include sufficient detail and/or tacit knowledge (subtle skills and extemporisations not considered notable) for the replication to succeed. One cause of replication failure is insufficient control of the protocol, which can cause disputes between the original and replicating researchers. [2]
In Economics, a replication of 18 experimental studies in two major journals, found a failure rate comparable to psychology or medicine (39%). [39] Several global surveys have reported a growing uneasiness of scientific communities over reproducibility and other issues of research transparency.
Ioannidis's theoretical model fails to account for that, but when a statistical method ("z-curve") to estimate the number of unpublished non-significant results is applied to two examples, the false positive rate is between 8% and 17%, not greater than 50%. [14]
An investigation by the UK scientific journal Nature published on 8 January 2020, found that eight James Cook University (JCU) studies on the effect of climate change on coral reef fish, one of which was authored by the JCU educated discredited scientist Oona Lönnstedt, had a 100 percent replication failure and thus none of the findings of the ...
Bill Gates and Mark Cuban swear that failure helped build their billion-dollar ideas, but new research says making mistakes isn’t actually a key to success Lindsey Leake June 20, 2024 at 1:00 PM
In "A Complete Unknown," those shouts take place during his raucous 1965 Newport Folk Festival show, known as the moment "Dylan went electric."
Example of direct replication and conceptual replication. There are two main types of replication in statistics. First, there is a type called “exact replication” (also called "direct replication"), which involves repeating the study as closely as possible to the original to see whether the original results can be precisely reproduced.
