This thought process is an example of using inductive reasoning, a logical process used to draw conclusions. So, when you give an inductive argument for a conclusion, you’re not intending it to be read as valid. Lawyers and Scientists use facts followed by evidence to prove their statement. Take Away Point: Both arguments are attempting to provide conclusive evidence for the conclusion. So, Wen Ho Lee is an Internet hacker and spy for the Chinese government. In psychology, inductive reasoning or 'induction' is defined as reasoning based on detailed facts and general principles, which are eventually used to reach a specific conclusion. A strong, inductive argument is such that that it is improbable that the premises are true and the conclusion is false. A strong inductive argument will present multiple, convincing examples in order to establish that it is not presenting a fluke or a series of flukes.

Therefore, Britney Spears probably likes to play sports. If the inductive argument is not only strong but also has all true premises, then it is called cogent. On the contrary, in deductive reasoning, the argument can be proved valid or invalid. We said that inductive arguments are “defeasible,” meaning that we could turn a strong inductive argument into a weak inductive argument simply by adding further premises to the argument. But clearly the second inductive argument is stronger than the first one. Bill usually eats lunch at noon, and it’s noon right now, so Bill is probably eating lunch right now. It has more evidence.

(1:41), Quiz: Inductive Arguments and Strong Reasoning, 3. So, if this argument does it, it's a good argument. To call an argument STRONG is to say something about the logical properties of the argument itself (that if the premises are true, the conclusion is very likely true). And so we need to figure out how to tell when a generalization from a sample is a strong argument. Consider the take away message from this example. For this reason, we need a different term for evaluating inductive arguments. This is an argument in which the premises are supposed to support the conclusion in such a way that if the premises are true, it is improbable that the conclusion would be false. There are basketball players from the 1980s who have scored at least 5 points on average. An Inductive argument which others call the inductive reasoning is actually an argument which is intended to be so strong. Inductive Arguments and Scientific Reasoning The second argument also has a big generalization as a conclusion, but the conclusion has a higher probability and involves less risk.

Inductive arguments are said to be either strong or weak. The judgment may not necessarily be true. Here is an example : (Premise 1) X and Y are similar in that they are both isosceles triangles (an isosceles triangle is a triangle with two equal sides). Most of our future discussion on inductive reasoning will be on how to make inductive arguments stronger, and avoid weak inductive arguments such as those discussed in Chapter 5. Many weeks of observation by trained observers v only one day by untrained observers.
