Question 1 1 p Which of the following is a valid scientific argument? 18. If a deductive argument is valid, that means the reasoning process behind the inferences is correct and there are no fallacies. Inductive Arguments and Scientific Reasoning. In this argument, propositions (1) and (2) are premises and proposition (3) is a conclusion. In debate or discussion, therefore, an argument may be attacked in two ways: by attempting to show that one of its premises is false or by attempting to show that it is invalid.

The following are examples of pseudosciences discussed in your textbook (see p. xxiii): • Phrenology • Subliminal perception • Iridology answer choices . In many cases, the premises and the conclusion will be linked by a series of intermediate steps. C. Validity (in the technical sense just defined) applies only to arguments, never to individual claims. Scientific arguments are logical descriptions of a scientific idea and the evidence for or against it. An argument contains a set of premises at the beginning and a conclusion at the end.

Then the following arguments (called specialization) are valid: p∧q p … For example: Premise 1: All cats are mammals. An argument is valid =df If all the premises are true, then the conclusion must be true. b. Scientific disagreements are usually very easy to resolve - it is usually the side that cites it's resources, and is more articulate, and is more skeptical, that is likely to be the right side in a given argument over the facts. Explanation: A claim is an interpretation based on the results of a given experiment, you first observe, and interpret the information. Scientists identify weaknesses and limitations in others' arguments, with the ultimate goal of refining and improving scientific explanations and experimental designs. The sea level measurements at the Gulf Coast this year were lower than normal; the average monthly measurements were about 0.1 cm lower than usual in some areas. (Specialization) Suppose p and q are statement forms. The Rogerian model of argument was developed by Carl R. Rogers to analyze an argument while providing a middle ground between opposing parties.

The hard sciences generally use inductive inference, including the hypothetico-deductive method. It is possible to have a deductive argument that is logically valid but is not sound. This often includes scientific principles and definitions related to our unit of study. The following is an example of an argument that is “valid”, but not “sound”: Everyone who eats carrots is a quarterback.
