The validation of complex structural models - i.e. the assessment of their quality compared to an experimental reference - remains a major issue today. The true validation problem should be addressed through comparison of the model used classically - whether it is deterministic or not - with the complete reality. A tentative answer through the Lack-Of-Knowledge (LOK) theory was introduced in [1
