How to Write a Deductive Essay - Top Tips!

The deductive style of writing is a distinctive style and it is an essential tool for evaluating student knowledge in almost every academic discipline.

As an art, the roots of deductive reasoning can be found in the notion that, based on certain circumstances, clues, or premises, a writer can come to well-reasoned conclusions in relation to a particular situation. Or, more simply put, it is possible to solve a puzzle or perplexing situation or find out the identity of a person if enough information is available.

In particular, deductive reasoning looks at a number of separate factors or facts, assesses these in terms of what is already known about a certain situation or set of circumstances, and draws every element together to come to logical conclusions. There can be several premises to any argument. The next essential element is evidence, which is any item of information available to a writer. This could be a story the writer is reading and analyzing or some particular thing they have observed. The last vital element is the conclusion. This part is the final decision or analysis the writer makes or how they see a given situation. It is usual to arrive at conclusions by balancing out the clues or premises with the evidence that is available. Here is a simplified example of deductive reasoning:

  • Assume the premise is:             Girls are female
  • Assume the evidence is:            Jennifer is a girl
  • Thus, it can be concluded that:  Jennifer is female.

Even though this example is extremely simple, it is accurate

People use deductive reasoning to a large extent every day. For example, you notice the street outside is wet. There are various ways you might interpret this information. It could be that a street-cleaning truck went past and wet the street. It may even be that there was a water leak and water gushed up from underground onto the street. Yet, the likeliest scenario is that it was raining. Considering all likely factors and based on life experience, and despite the fact there may be other reasons, logic would suggest that the street is wet because it was raining. If, however, you were confident there had been no rainfall or that there was no street cleaning in progress, you would alter your reasoning accordingly. The art of deduction chooses the option that is most reasonable and likely, although it is not necessarily certain. Some specialist fields of study and work rely on deduction such as police and legal work, investigative reporting, some aspects of medicine, the sciences and, somewhat surprisingly, the analysis of literature.   

Being clear and staying focused are key elements of a good deductive essay. Each paragraph should focus on one point or element of the topic and you should use precise detail and examples to come to specific conclusions. The type of support the writer puts forward for arriving at a particular conclusion is one of the most essential factors in an essay of this type. In other words, your conclusion is likely to come across as weak and feeble unless it is well supported.  

Below are a few popular topic ideas for deductive essays:
