Types of Reasoning

Reasoning can take many forms, ranging from simple decision-making to complex algorithms that fuel artificial intelligence. Formal reasoning can be found in well-known areas including mathematics, logic, artificial intelligence, and philosophy. However, you may categorise thinking into seven main forms in any situation. Understanding the different styles of reasoning can assist you in evaluating and improving your decision-making process.

What is the definition of reasoning?

When making a choice or addressing an issue, reasoning is the ability to appraise things rationally by using logic based on new or existing information. Reasoning allows you to balance the advantages and cons of two or more options before deciding on the best option or the one that best meets your goals. It also assists you in solving difficulties, dealing with uncertainty, verifying claims, and carefully assessing situations to ensure that the decision you make is in your best interests.

Types of Reasoning:

1. Deductive reasoning:

Deductive reasoning is a method of proving a theory or hypothesis using formal logic and observations. Deductive reasoning starts with a hypothesis that is then supported or disproved through observations or rational thought.

A marketing division, for example, analyses data and confirms that their company’s most important demographic is young parents. They opt to give more of the marketing money to social media channels that target that category based on this information.

2. Inductive reasoning:

To validate observations, inductive reasoning employs theories and assumptions. It’s the polar opposite of deductive reasoning in that it requires deducing a general rule from a specific case or cases.

Because it employs conclusions from observations to make generalisations, the outcomes of inductive reasoning are not always certain. Extrapolation, forecasts, and part-to-whole arguments all benefit from inductive reasoning.

3. Analogical reasoning:

Analogical reasoning is a style of reasoning that looks for similarities between two or more objects and then uses those similarities to find other properties they share. It is based on the brain’s tendency to notice patterns and make connections.

4. Abductive reasoning:

Abductive reasoning is a style of reasoning that reaches a logical conclusion based on an observation or group of observations. Abductive reasoning is similar to inductive reasoning, but it allows you to make the greatest estimates to get the simplest conclusions. Abduction can help with both troubleshooting and decision-making, especially when dealing with uncertainties.

5. Cause-and-effect reasoning:

Cause-and-effect reasoning is a style of reasoning in which the relationship between two events is demonstrated. This logic is used to describe what might happen if a certain action is taken or why certain things happen when certain circumstances are met. When people draw on personal experience and a drive to improve, this form of reasoning is frequently used to guide daily decision-making.

6. Critical thinking:

Critical thinking entails delving deeply into a topic’s rationale in order to reach a definitive conclusion. Computing, engineering, social sciences, and logic all benefit from it. When it comes to problem-solving, critical thinking is especially important when dealing with technological challenges. It’s used to determine the validity of artworks, literature, films, and other forms of art.

7. Decompositional reasoning:

Decompositional reasoning is the process of breaking things down into their basic components in order to comprehend how each component contributes to the overall functionality of the object. Decompositional reasoning allows an observer to derive powerful conclusions about the total by evaluating each portion separately.

Syllogism:

The syllogism is an essential component of all aptitude questions. It falls within the area of logical thinking. Due to their perplexing character, syllogisms have risen to prominence in aptitude tests over time.

The topic of syllogism is quite popular in government exams, and questions about it are almost always asked, as witnessed in recent years. As a result, a thorough comprehension of the concept is critical.

Modus Ponens and Modus Tollens:

In propositional logic, the modus ponens and modus tollens  are two types of inference that can be derived from a hypothetical proposition—that is, from a statement of the form “If A, then B” (symbolicallyA ⊃ B, in which “If… then”). Inferences of the type A ⊃ B,; A, therefore B are known as modus ponens. The term “modus tollens” refers to conclusions of the type A ⊃ B;; B, therefore, A (which means “not”). An example of modus tollens is as follows:

When an angle is inscribed in a semicircle, it is a right angle; however, this angle is not a right angle, hence it is not inscribed in a semicircle.

The phrases modus tollendo ponens and modus ponendo ponens are used for arguments of the types A B; A, therefore B, and A B; A, therefore B (valid only for exclusive disjunction: “Either A or B but not both”) for disjunctive premises (employing, which means “either… or”). Almost every formal system of logic incorporates the rule of modus ponens.

Conclusion 

Because reasoning abilities affect how people interpret, assess, and accept facts and arguments, it has a significant impact on one’s ability to learn from new information and experiences.

Deductive and inductive reasoning are important to study and practise because they strengthen your critical thinking skills, which help you improve your problem-solving abilities, increase your interpersonal and leadership skills, and help you empathise with others.
