There are several ways to present information when writing, including those that employ inductive and deductivereasoning. The difference can be stated simply:
- Inductive reasoning presents facts and then wraps them up with a conclusion.
- Deductive reasoning presents a thesis statement and then provides supportive facts or examples.
Which should the writer use? It depends on content, the intended audience, and your overall purpose.
If you want your audience to discover new thingswith you, then inductive writing might make sense. Here is n example:
My dog Max wants to chase every non-human living creature he sees, whether it is the cats in the house or rabbits and squirrels in the backyard. Sources indicate that this is a behavior typical of Jack Russell terriers. While Max is a mixed breed dog, he is approximately the same size and has many of the typical markings of a Jack Russell. From these facts along with his behaviors, we surmise that Max is indeed at least part Jack Russell terrier.
Within that short paragraph, you learned about Max’s manners and a little about what he might look like, and then the concluding sentence connected these ideas together. This kind of writing often keeps the reader’s attention, as he or she must read all the pieces of the puzzle before they are connected.
Purposes for this kind of writing include creative writing and perhaps some persuasive essays, although much academic work is done in deductive form.
If your audience is not likely going to read the entire written piece, then deductive reasoning might make more sense, as the reader can look for what he or she wants by quickly scanning first sentences of each paragraph. Here is an example:
My backyard is in dire need of cleaning and new landscaping. The Kentucky bluegrass that was planted there five years ago has been all but replaced by Creeping Charlie, a particularly invasive weed. The stone steps leading to the house are in some disrepair, and there are some slats missing from the fence. Perennials were planted three years ago, but the moles and rabbits destroyed many of the bulbs, so we no longer have flowers in the spring.
The reader knows from the very first sentence that the backyard is a mess! This paragraph could have ended with a clarifying conclusion sentence; while it might be considered redundant to do so, the scientific community tends to work through deductive reasoning by providing (1) a premise or argument – which could also be called a thesis statement, (2) then evidence to support the premise, and (3) finally the conclusion.
Purposes for this kind of writing include business letters and project documents, where the client is more likely to skim the work for generalities or to hunt for only the parts that are important to him or her. Again, scientific writing tends to follow this format as well, and research papers greatly benefit from deductive writing.
Whether one method or another is chosen, there are some other important considerations. First, it is important that the facts/evidence be true. Perform research carefully and from appropriate sources; make sure ideas are cited properly. You might need to avoid absolute words such as “always,” “never,” and “only,” because they exclude any anomalies. Try not to write questions: the writer’s job is to provide answers instead. Lastly, avoid quotes in thesis statements or conclusions, because they are not your own words – and thus undermine your authority as the paper writer.

Some basic guidelines
The best time to think about how to organize your paper is during the pre-writing stage, not the writing or revising stage. A well-thought-out plan can save you from having to do a lot of reorganizing when the first draft is completed. Moreover, it allows you to pay more attention to sentence-level issues when you sit down to write your paper.
When you begin planning, ask the following questions: What type of essay am I going to be writing? Does it belong to a specific genre? In university, you may be asked to write, say, a book review, a lab report, a document study, or a compare-and-contrast essay. Knowing the patterns of reasoning associated with a genre can help you to structure your essay.
For example, book reviews typically begin with a summary of the book you’re reviewing. They then often move on to a critical discussion of the book’s strengths and weaknesses. They may conclude with an overall assessment of the value of the book. These typical features of a book review lead you to consider dividing your outline into three parts: (1) summary; (2) discussion of strengths and weaknesses; (3) overall evaluation. The second and most substantial part will likely break down into two sub-parts. It is up to you to decide the order of the two subparts—whether to analyze strengths or weaknesses first. And of course it will be up to you to come up with actual strengths and weaknesses.
Be aware that genres are not fixed. Different professors will define the features of a genre differently. Read the assignment question carefully for guidance.
Understanding genre can take you only so far. Most university essays are argumentative, and there is no set pattern for the shape of an argumentative essay. The simple three-point essay taught in high school is far too restrictive for the complexities of most university assignments. You must be ready to come up with whatever essay structure helps you to convince your reader of the validity of your position. In other words, you must be flexible, and you must rely on your wits. Each essay presents a fresh problem.
Avoiding a common pitfall
Though there are no easy formulas for generating an outline, you can avoid one of the most common pitfalls in student papers by remembering this simple principle: the structure of an essay should not be determined by the structure of its source material. For example, an essay on an historical period should not necessarily follow the chronology of events from that period. Similarly, a well-constructed essay about a literary work does not usually progress in parallel with the plot. Your obligation is to advance your argument, not to reproduce the plot.
If your essay is not well structured, then its overall weaknesses will show through in the individual paragraphs. Consider the following two paragraphs from two different English essays, both arguing that despite Hamlet’s highly developed moral nature he becomes morally compromised in the course of the play:
(a) In Act 3, Scene 4, Polonius hides behind an arras in Gertrude’s chamber in order to spy on Hamlet at the bidding of the king. Detecting something stirring, Hamlet draws his sword and kills Polonius, thinking he has killed Claudius. Gertrude exclaims, “O, what a rash and bloody deed is this!” (28), and her words mark the turning point in Hamlet’s moral decline. Now Hamlet has blood on his hands, and the blood of the wrong person. But rather than engage in self-criticism, Hamlet immediately turns his mother’s words against her: “A bloody deed – almost as bad, good Mother, as kill a king, and marry with his brother” (29-30). One of Hamlet’s most serious shortcomings is his unfair treatment of women. He often accuses them of sins they could not have committed. It is doubtful that Gertrude even knows Claudius killed her previous husband. Hamlet goes on to ask Gertrude to compare the image of the two kings, old Hamlet and Claudius. In Hamlet’s words, old Hamlet has “Hyperion’s curls,” the front of Jove,” and “an eye like Mars” (57-58). Despite Hamlet’s unfair treatment of women, he is motivated by one of his better qualities: his idealism.
(b) One of Hamlet’s most serious moral shortcomings is his unfair treatment of women. In Act 3, Scene 1, he denies to Ophelia ever having expressed his love for her, using his feigned madness as cover for his cruelty. Though his rantings may be an act, they cannot hide his obsessive anger at one particular woman: his mother. He counsels Ophelia to “marry a fool, for wise men know well enough what monsters you make of them” (139-41), thus blaming her in advance for the sin of adultery. The logic is plain: if Hamlet’s mother made a cuckold out of Hamlet’s father, then all women are capable of doing the same and therefore share the blame. The fact that Gertrude’s hasty remarriage does not actually constitute adultery only underscores Hamlet’s tendency to find in women faults that do not exist. In Act 3, Scene 4, he goes as far as to suggest that Gertrude shared responsibility in the murder of Hamlet’s father (29-30). By condemning women for actions they did not commit, Hamlet is doing just what he accuses Guildenstern of doing to him: he is plucking out the “heart” of their “mystery” (3.2.372-74).
The second of these two paragraphs is much stronger, largely because it is not plot-driven. It makes a well-defined point about Hamlet’s moral nature and sticks to that point throughout the paragraph. Notice that the paragraph jumps from one scene to another as is necessary, but the logic of the argument moves along a steady path. At any given point in your essays, you will want to leave yourself free to go wherever you need to in your source material. Your only obligation is to further your argument. Paragraph (a) sticks closely to the narrative thread of Act 3, Scene 4, and as a result the paragraph makes several different points with no clear focus.
What does an essay outline look like?
Most essay outlines will never be handed in. They are meant to serve you and no one else. Occasionally, your professor will ask you to hand in an outline weeks prior to handing in your paper. Usually, the point is to ensure that you are on the right track. Nevertheless, when you produce your outline, you should follow certain basic principles. Here is an example of an outline for an essay on Hamlet:
|thesis: Despite Hamlet’s highly developed moral nature, he becomes morally compromised while delaying his revenge.|
|I.||Introduction: Hamlet’s father asks Hamlet not only to seek vengeance but also to keep his mind untainted.|
|II.||Hamlet has a highly developed moral nature.|
|A.||Hamlet is idealistic.|
|B.||Hamlet is aware of his own faults, whereas others are self-satisfied.|
|C.||Hamlet does not want to take revenge without grounds for acting.|
|III.||Hamlet becomes morally compromised while delaying.|
|A.||The turning point in Hamlet’s moral decline is his killing of Polonius.|
|B.||Hamlet’s moral decline continues when he sends Rosencrantz and Guildenstern to their death.|
|C.||Hamlet already began his moral decline before the turning point in the play, the killing of Polonius.|
|1.||Hamlet treats women badly.|
|2.||Hamlet criticizes others in the play for acting falsely to get ahead, but in adopting the disguise of madness he, too, is presenting a false face to the world.|
|IV.||Though Hamlet becomes more compromised the longer he delays, killing the king would have been a morally questionable act.|
|V.||Conclusion: The play Hamlet questions the adequacy of a system of ethics based on honour and revenge.|
This is an example of a sentence outline. Another kind of outline is the topic outline. It consists of fragments rather than full sentences. Topic outlines are more open-ended than sentence outlines: they leave much of the working out of the argument for the writing stage.
When should I begin putting together a plan?
The earlier you begin planning, the better. It is usually a mistake to do all of your research and note-taking before beginning to draw up an outline. Of course, you will have to do some reading and weighing of evidence before you start to plan. But as a potential argument begins to take shape in your mind, you may start to formalize your thoughts in the form of a tentative plan. You will be much more efficient in your reading and your research if you have some idea of where your argument is headed. You can then search for evidence for the points in your tentative plan while you are reading and researching. As you gather evidence, those points that still lack evidence should guide you in your research. Remember, though, that your plan may need to be modified as you critically evaluate your evidence.
Some techniques for integrating note-taking and planning
Though convenient, the common method of jotting down your notes consecutively on paper is far from ideal. The problem is that your points remain fixed on paper. Here are three alternatives that provide greater flexibility:
method 1: index cards
When you are researching, write down every idea, fact, quotation, or paraphrase on a separate index card. Small (5″ by 3″) cards are easiest to work with. When you’ve collected all your cards, reshuffle them into the best possible order, and you have an outline, though you will undoubtedly want to reduce this outline to the essential points should you transcribe it to paper.
A useful alternative involves using both white and coloured cards. When you come up with a point that you think may be one of the main points in your outline, write it at the top of a coloured card. Put each supporting note on a separate white card, using as much of the card as necessary. When you feel ready, arrange the coloured cards into a workable plan. Some of the points may not fit in. If so, either modify the plan or leave these points out. You may need to fill gaps by creating new cards. You can shuffle your supporting material into the plan by placing each of the white cards behind the point it helps support.
method 2: the computer
A different way of moving your notes around is to use the computer. You can collect your points consecutively, just as you would on paper. You can then sort your ideas when you are ready to start planning. Take advantage of “outline view” in Word, which makes it easy for you to arrange your points hierarchically. This method is fine so long as you don’t mind being tied to your computer from the first stage of the writing process to the last. Some people prefer to keep their planning low-tech.
method 3: the circle method
This method is designed to get your ideas onto a single page, where you can see them all at once. When you have an idea, write it down on paper and draw a circle around it. When you have an idea which supports another idea, do the same, but connect the two circles with a line. Supporting source material can be represented concisely by a page reference inside a circle. The advantage of the circle method is that you can see at a glance how things tie together; the disadvantage is that there is a limit to how much material you can cram onto a page.
Here is part of a circle diagram:
What is a reverse outline?
When you have completed your first draft, and you think your paper can be better organized, consider using a reverse outline. Reverse outlines are simple to create. Just read through your essay, and every time you make a new point, summarize it in the margin. If the essay is reasonably well-organized, you should have one point in the margin for each paragraph, and your points read out in order should form a coherent argument. You might, however, discover that some of your points are repeated at various places in your essay. Other points may be out of place, and still other key points may not appear at all. Think of all these points as the ingredients of an improved outline which you now must create. Use this new outline to cut and paste the sentences into a revised version of your essay, consolidating points that appear in several parts of your essay while eliminating repetition and creating smooth transitions where necessary.
You can improve even the most carefully planned essay by creating a reverse outline after completing your first draft. The process of revision should be as much about organization as it is about style.
How much of my time should I put into planning?
It is self-evident that a well-planned paper is going to be better organized than a paper that was not planned out. Thinking carefully about how you are going to argue your paper and preparing an outline can only add to the quality of your final product. Nevertheless, some people find it more helpful than others to plan. Those who are good at coming up with ideas but find writing difficult often benefit from planning. By contrast, those who have trouble generating ideas but find writing easy may benefit from starting to write early. Putting pen to paper (or typing away at the keyboard) may be just what is needed to get the ideas to flow.
You have to find out for yourself what works best for you, though it is fair to say that at least some planning is always a good idea. Think about whether your current practices are serving you well. You know you’re planning too little if the first draft of your essays is always a disorganized mess, and you have to spend a disproportionate amount of time creating reverse outlines and cutting and pasting material. You know you’re planning too much if you always find yourself writing your paper a day before it’s due after spending weeks doing research and devising elaborate plans.
Be aware of the implications of planning too little or too much. Planning provides the following advantages:
- helps you to produce a logical and orderly argument that your readers can follow
- helps you to produce an economical paper by allowing you to spot repetition
- helps you to produce a thorough paper by making it easier for you to notice whether you have left anything out
- makes drafting the paper easier by allowing you to concentrate on writing issues such as grammar, word choice, and clarity
Overplanning poses the following risks:
- doesn’t leave you enough time to write and revise
- leads you to produce papers that try to cover too much ground at the expense of analytic depth
- can result in a writing style that lacks spontaneity and ease
- does not provide enough opportunity to discover new ideas in the process of writing
