Induction can be divided into complete induction and incomplete induction.

Complete induction: Complete induction refers to the inference that every object of the same kind of thing has (or does not have) a certain attribute and deduces the general conclusion that this kind of thing has (or does not have) this attribute.

Incomplete induction: Incomplete induction is the inference that all objects in a certain class have (or do not have) certain attributes. It can be divided into simple enumeration induction and scientific induction.

Science popularization:

Induction generally refers to inductive reasoning, which is a kind of reasoning from individual to general. From a certain point of view about individual things to a larger point of view, the general principle and the explanation method of the principle are deduced from special concrete examples.

1, the thinking process of inductive reasoning is from individual to general, while the thinking process of deductive reasoning is not from individual to general, but an inevitable thinking process.

2. In inductive reasoning, except that the connection between premise and conclusion is inevitable, the connection between premise and conclusion is probable, that is to say, the premise is true and the reasoning form is correct, but it may not necessarily lead to a true conclusion.

There are two common definitions of induction:

1, defined as the method of drawing general conclusions from individual premises; According to this definition, it includes simple enumeration induction, complete induction, scientific induction, elimination induction by John Mill and Wright, inverse reasoning and mathematical induction.

2. Another definition is the method of drawing conclusions from individual premises; According to this definition, it includes simple enumeration induction, elimination induction by John Mill and Wright, backward deduction and analogy, but it does not include complete induction, scientific induction and mathematical induction.
