To deduce is to infer certain consequences from general premises (assumptions, propositions). Infer means to form an opinion, to reach a conclusion based on facts. Stated simply, to apply the general to the specific. This is a central part of how Germans think.
Deductive thinking is in German commercial law. What work processes should look like are very specifically defined. They should, for example, be based on German laws governing safety, but be shaped by overall knowledge of the respective company.
Work process, therefore, are based both on theory (safety laws) and on practice (knowhow developed over years).
The renowned German dual vocational training is based on this logic. The students in vocational schools learn at the same time theory and practice (or application). The so-called gray theory – classroom learning – is a requirement.
