|Description=Like [[Demarcation Criteria|demarcation]] and [[Acceptance Criteria|acceptance criteria]], compatibility criteria can be part of a community's employed method. The community employs these criteria to determine whether two theories are mutually compatible or incompatible, i.e. whether they can be simultaneously part of the community's mosaic. Different communities can have different compatibility criteria. While some communities may opt to employ the logical law of noncontradiction as their criterion of compatibility, other communities may be more tolerant towards logical inconsistencies. According to Barseghyan, the fact that these days scientists "often simultaneously accept theories which strictly speaking logically contradict each other is a good indication that the actual criteria of compatibility employed by the scientific community might be quite different from the classical logical law of noncontradiction".[[CiteRef::Barseghyan (2015)|p. 11]]  After a community has satisfied both ''demarcation criteria'' and ''acceptance criteria,'' the community in question must properly define ''compatibility criteria'' so as to determine whether two theories are mutually compatible or incompatible. If two incompatible theories are employed for the same domain at the same time, the logic law of noncontradiction would be violated. However, the '''compatibility criteria''' may turn out to be changeable and may need not necessarily coincide with the logical law of noncontradiction. [[CiteRef::Barseghyan (2015)|p. 13]] Thus, a proper definition of ''compatibility criteria'' is of great importance in order to explicate any method.
