What is deductive reasoning? (hypothesis-based)
a form of logical thinking that uses a general principle or law to forecast specific results
Deductive reasoning, also known as hypothesis-based reasoning, is a logical process in which a specific conclusion is drawn from a general premise or set of premises. In other words, it is a form of reasoning that moves from general principles or assumptions to specific conclusions.
The process of deductive reasoning involves analyzing existing knowledge, identifying a hypothesis or prediction based on that knowledge, and then testing the hypothesis or prediction through observation or experimentation. The conclusion that is drawn from the testing of the hypothesis is then used to either confirm or reject the initial premise or set of premises.
For example, a simple deduction might involve the following premises:
1. All mammals have fur.
2. Dogs are mammals.
Using deductive reasoning, we can conclude that:
3. Therefore, dogs have fur.
In this case, the conclusion is necessarily true based on the two premises that were provided.
Deductive reasoning is commonly used in the scientific method, where hypotheses are formulated and then tested through experimentation to draw conclusions about the natural world. It is also utilized in mathematics and philosophy to make logical arguments based on established principles or axioms.
