The Center for Open Science, has been pursuing a unique project from November 2011. This involved repeating about hundred experiments in psychology in order to see whether the second round of results would be the same. The first set of results that were observed to have been released in Science edition, which shows that the repetitions were less than half among these experiments.
The studies involved cognitive as well as social psychology topics, subjects that do not have any direct significance when it comes to medical or therapeutic treatments. However, for the public, scientists and the world of science in general the findings are significant. The main take away from this conclusion is that, no study and its findings can be considered to be the final word on any matter which relates to human psychology.
As a result, there can be several competing findings and studies that will suggest different remedies or conclusions to a same problem. Problems in human behavior, especially cognitive and social aspects are studied in order to understand the causes, effects and influences, but it might remain murky and no single study or its findings can be considered to be conclusive.
If replication cannot be achieved, it poses a problem for many scientific subjects. That can be biomedical disciplines or psychology. A single experiment has its limitations and it might fail to give definitive answers which might differ the second time round. This might be because experiments are usually conducted under restrictive conditions. Again, the experimenters need to take several decisions that are usually based on personal preferences and judgment like samples to be studied, how to pick the sample, what to include and what to exclude and even matters like methods to use for the experiment, analysis of the results or explanation of the results.
A question needs to be looked at from several angles in order to understand how it looks from a comprehensive angle as well as replicating the results of the experiments time and again. In certain cases the decisions that are taken might be fraudulent as well as mistakes that are committed unwittingly.
With these implications, it is best that researchers take up original subjects to research upon rather than trying to replicate a study that has already been covered by someone else. Scientific journals are also more tuned to accepting original research topics that publishing matter that has been covered previously in a different angle. However, certain findings, which influence decisions in related fields, can be questioned if the same experiment is replicated to verify the findings.
