40 examples of inductive and deductive arguments
Inductive and deductive arguments are two types of reasoning that allow us to reach conclusions from a premise.
The premises of inductive arguments identify repeated patterns in a sample of a population, and from there general conclusions are inferred for the entire population. Such conclusions are always considered probable.
In deductive arguments, on the other hand, the premises from which we start are general principles, from which conclusions about specific cases are inferred. Unlike the inductive, the conclusions of the deductive argument are always considered valid. Next, we offer a list with a total of 40 examples, distributed in 20 inductive arguments and 20 deductive arguments.
