There is no reason why the work of scientists has to be officially confirmed before being published  There is a system in place for the confirmation or disconfirmation of scientific findings, namely, the replication of results by other scientists  Poor scientific work on the part of any one scientist, which can include anything from careless reporting practices to fraud, is not harmful
It will be exposed and rendered harmless when other scientists conduct the experiments and obtain disconfirmatory results
Scientific experiments can go unchallenged for many years before they are replicated.
