Good Agreement Science
Most models of scientific change are based on new data generated by scientific experiments. Karl Popper suggested that because no amount of experiments has ever been able to prove a scientific theory, but only one experiment could refute one, science should be based on counterfeiting.  Although this is a logical theory for science, it is, in a sense, « timeless » and does not necessarily reflect a view of how science should progress over time. Consensus is achieved through communication at conferences, the publication process, the replication of results reproducible by other scientific debates and peer review. A consensus conference is called a consensus conference.    Such measures lead to a situation in which those in discipline can often discern such a consensus where it exists; However, it can be difficult to tell outsiders that a consensus has been reached, as the « normal » debates by which science progresses may appear to be an external challenge.  Sometimes scientific institutes publish opinions to convey a summary of the science of the « inside » to the « outside » of the scientific community. In cases where there is little controversy on the subject under consideration, the definition of consensus can be quite simple. 2.
