The Differences Between Deductive and Inductive Arguments

Compare , contrast and examples


Deductive arguments are formed when the conclusion can be derived as true, by way of the premise being true. This type of argument relates two things together by common factors to come to the conclusion the truths of both.


In contrast, inductive reasoning can pair together two unrelated subjects as a premise and conclusion, linking them together where fact is not present. The premise may not be the same truth as the conclusion, but a probability. They are both a type of reasoning that compares ideas to find similar truths, however, inductive adds more chance and variance that will not always make both true.


Inductive reasoning is used in many venues to scare people into buying higher priced items. Low-Fat and All Natural are words that are slapped on higher priced grocery items to illicit a sale, however some may have more sugar and additives than their cheaper, less advertised competitors. Studies are always posted with “controversial” findings that with a deeper look, the controversy is really in what their finding were. Too many times, not all differing factors are considered and it seems that findings are bias to the person footing the bill of the studies. A great example would be eggs. One year they are good for you and the next year, there are a million ads claiming how eggs are the super food and we just can’t live without them. Like so many things in this world, it is almost always open to interpretation.


I used to own a restaurant years ago and had decided to change one of my main dishes recipes and was curious how my customers felt about it, as well as other things. I decided the best way was to have an open comment card box always stocked with cards asking the questions I wanted to know. I feel that by letting a person to it on their own accord, as well as having only customers answer the questionnaire, I had the best chance of finding out what my customers really wanted. The more comment cards filled out gave me a better understanding of what was wanted or needed changing and was very helpful.

Interesting topic. It can get very confusing. Those looking for sources of "authority" are also prone to being misled. I think it can be very helpful to question the motive of those making various statements. If trusting the source, it is safe to assume the statement is also sound - and vice versa.
