      Scientific Knowledge is Open to Revision in Light of New Evidence

      • Science findings are frequently revised and/or reinterpreted based on new evidence.
      • Most scientific knowledge is quite durable, but is, in principle, subject to change based on new evidence and/or reinterpretation of existing evidence.
      • Scientific argumentation is a mode of logical discourse used to clarify the strength of relationships between ideas and evidence that may result in revision of an explanation.
