Difference Between Inductive and Deductive

Difference Between Inductive and Deductive

Today, we are going to treat a very important topic. These terms are commonly applied in the area of reasoning to describe how people reach a conclusion about a subject. A lot of times, the two adjectives are used based on evidence. Without much ado, we will delve into the topic right now. The question that many online searchers usually ask is, what does inductive and deductive mean? Indeed, this question keeps recurring because people don’t seem to have the clear disparity between the two words.

So, if you are one of those struggling to differentiate between the two words, we assure you that you have nothing to worry about because we will help you to spot the difference between inductive and deductive. To achieve that, we will use definitions of the two terms, inductive and deductive examples, and everything else that we will consider relevant to this article. Now, let’s get into the nitty-gritty of today’s exercise.

What is the Difference Between Inductive and Deductive?

The best way of differentiating between the two is with the help of deductive and inductive examples.

We can start with inductive reasoning.

Someone can draw a conclusion from the following hypothesis:

My elder brother like to eat pizza a lot.

My friend’s older brother loves pizza too.

My colleague’s big brother loves pizza so much.

Therefore, all elder brothers love pizza.

While this may sound so convincing to the logically, it is not entirely true. Indeed, this is one way that you may reach a conclusion based on probability.

In a similar vein, we can have the following example for deductive reasoning.

Every human being must die.

Josh is a human being.

Therefore, Josh must die.

Indeed, it is obvious that the statement above is correct regardless of the circumstance that is being considered.

Definitions of Inductive and Deductive

What is inductive and deductive? To help have a good grasp of the two words, we will relate it to reasoning and logic, which is the most common applications of the two adjectives. Starting with inductive, this involves reaching a conclusion of a case based on the evidence that you have seen. The definition of truth in this context is not based on what is perceived or experienced but it is hinges on the facts and proofs that are available to the decider.

This is the commonly used method for passing verdicts in court as the jury depends on the available evidence tendered in court to reach a conclusion or pass a judgment. This method of reasoning promotes certainty, something that is certain. From the foregoing, one can say that the decision reached from this type of reasoning is far much better than any other because it is easy to convince all the parties involved, especially if it has to do with a law court.

On the other hand, inductive reasoning and conclusion could be untrue or false because of the method used to arrive at it. Conclusion reached in this aspect is based on probability. This means that it is likely not to be true based on the premises that led to the conclusion. More often than not, people use hypothesis to draw its conclusion. It is also regarded as cause and effect reasoning. Although the argument may sound valid, it is not usually true.

Inductive vs Deductive Comparison Table

Well, someone may just ask you, what is the difference between inductive and deductive? The thing is, we have already answered that question, but we will still use a table, as show below, to differentiate between the two methods.  

Basis of Comparison Deductive Inductive
Conclusion Arriving at conclusion based on real logic and reasoning  Arriving at a conclusion based on hypothesis, which may be untrue
Acceptability   Generally true Most times, it is not completely true or outright falsehood  
Usage It is used in real-life situation It is rarely used  
– Start a theory
– Formulate hypothesis
– Test the hypothesis
– Draw a conclusion
– Observation
– Pattern Observation
– Develop a theory
– Reach a conclusion

Conclusion of the Main Difference Between Inductive vs Deductive

Wrapping up, we have been able to satisfactorily explain the difference between deductive and inductive reasoning. However, it is important to keep in mind that the two methods go through different stages before conclusions are drawn. For Inductive, it usually goes through General observation, pattern observation, and theory development (drawing a conclusion).

On the other hand, Deductive starts with an existing theory, theory formulation, data collection and hypothesis testing, analyzing the data and reaching a conclusion. Now, when you hear, “what is inductive and deductive logic?” You will definitely know what to answer. So, go ahead and teach others because teaching helps people to assimilate something perfectly.
