Models are inherently imperfect yet useful, a principle that extends to in vitro and in vivo data used in regulatory toxicology. The authors aim to summarize the thesis and antithesis about the utility of in vitro tests for regulatory use and propose a synthesis. The article argues against the claim that in vitro tests are useless for regulatory purposes, presenting a balanced discussion of thesis and antithesis.
"All models are wrong, some models are useful." George E.P. Box, "Robustness in the strategy of scientific model building", 1979. This quote from George Box was the title of a book chapter on mathematical models-exactly the type of models which we will not address here, although a lot of the general reasoning can as well be translated to them, especially because they depend on the input and thus on the limitations of either in vitro or in vivo data, when applied for regulatory toxicology. This article was prompted by the 2008 SOT/EuroTox debate (March 2008 in Seattle and October 2008 in Rhodes), which challenged us in an Hegelian approach as thesis and antithesis to present with changing roles on both occasions on the statement "In vitro tests are useless for regulatory use." Here, we would like following Hegel a summary of thesis and antithesis, but also try to outline the synthesis.
