3 possible outcomes of scientific inquiry?
Three possible outcomes of scientific inquiry are the confirmation of existing theories, the discovery of new phenomena, and the identification of errors in previous understandings. Confirmation strengthens the validity of established theories, while new discoveries can lead to the development of novel hypotheses and research directions. Identifying errors fosters a more accurate understanding of scientific concepts and encourages ongoing investigation and revision of knowledge.
What are the three conditons?
The "three conditions" typically refer to criteria necessary for specific outcomes in various contexts. For example, in the context of a valid argument, they might be sound premises, logical structure, and relevance. In scientific experiments, they could involve controlled variables, reproducible results, and clear hypotheses. If you provide more context, I can give a more tailored answer!
