Using Evidence: Analysis

Beyond introducing and integrating your paraphrases and quotations, you also need to analyze the evidence in your paragraphs. Analysis is your opportunity to contextualize and explain the evidence for your reader. Your analysis might tell the reader why the evidence is important, what it means, or how it connects to other ideas in your writing.

Note that analysis often leads to synthesis , an extension and more complicated form of analysis. See our synthesis page for more information.

Example 1 of Analysis

Without analysis.

Embryonic stem cell research uses the stem cells from an embryo, causing much ethical debate in the scientific and political communities (Robinson, 2011). "Politicians don't know science" (James, 2010, p. 24). Academic discussion of both should continue (Robinson, 2011).

With Analysis (Added in Bold)

Embryonic stem cell research uses the stem cells from an embryo, causing much ethical debate in the scientific and political communities (Robinson, 2011). However, many politicians use the issue to stir up unnecessary emotion on both sides of the issues. James (2010) explained that "politicians don't know science," (p. 24) so scientists should not be listening to politics. Instead, Robinson (2011) suggested that academic discussion of both embryonic and adult stem cell research should continue in order for scientists to best utilize their resources while being mindful of ethical challenges.

Note that in the first example, the reader cannot know how the quotation fits into the paragraph. Also, note that the word both was unclear. In the revision, however, that the writer clearly (a) explained the quotations as well as the source material, (b) introduced the information sufficiently, and (c) integrated the ideas into the paragraph.

Example 2 of Analysis

Trow (1939) measured the effects of emotional responses on learning and found that student memorization dropped greatly with the introduction of a clock. Errors increased even more when intellectual inferiority regarding grades became a factor (Trow, 1939). The group that was allowed to learn free of restrictions from grades and time limits performed better on all tasks (Trow, 1939).

In this example, the author has successfully paraphrased the key findings from a study. However, there is no conclusion being drawn about those findings. Readers have a difficult time processing the evidence without some sort of ending explanation, an answer to the question so what? So what about this study? Why does it even matter?

Trow (1939) measured the effects of emotional responses on learning and found that student memorization dropped greatly with the introduction of a clock. Errors increased even more when intellectual inferiority regarding grades became a factor (Trow, 1939). The group that was allowed to learn free of restrictions from grades and time limits performed better on all tasks (Trow, 1939). Therefore, negative learning environments and students' emotional reactions can indeed hinder achievement.

Here the meaning becomes clear. The study’s findings support the claim the reader is making: that school environment affects achievement.

How to Use Evidence and Analysis in Academic Essays

In academic essays, using evidence and analysis isn’t just helpful; it’s essential. Think of your essay as a building, where evidence and analysis are the bricks and mortar. They strengthen your arguments, making them more convincing.

Evidence gives solid ground to your claims, while analysis helps you delve deeper, showing your understanding of the topic. Together, they add credibility and persuasiveness, making your essay stand out.

So, as you write, remember the power of well-chosen evidence and thoughtful analysis. They’re your tools to build a compelling, credible argument that captures and keeps your reader’s attention.

The Role of Evidence in Essays

In an academic context, evidence includes data, facts, and authoritative opinions that support your essay’s arguments. It’s like the foundation of a building, providing solid ground for your ideas. Examples include statistics from reputable sources, quotes from experts, and results from scientific studies.

Evidence plays a crucial role in supporting your arguments, lending them weight and credibility. It’s what turns your personal opinions into well-substantiated claims. For instance, using a service like ‘ write my report services in USA ‘ can offer a great example of how to research and utilize evidence effectively.

Incorporating strong evidence is key to persuading your reader and enhancing the overall impact of your essay. It’s not just about what you say, but also about backing it up with concrete proof.

Types of Evidence

Various types of evidence can be used to bolster your essay, each suited to different topics. Empirical evidence, derived from observations or experiments, is ideal for scientific or social research essays. It offers tangible proof of your claims.

Anecdotal evidence, based on personal experiences or stories, can be effective in more narrative essays. It adds a human touch but should be used cautiously as it may not always be reliable.

Statistical evidence is powerful in argumentative essays, providing quantifiable data to support your points. It lends objectivity, especially in topics requiring numerical analysis.

Choosing the right type of evidence depends on your essay’s topic and the argument you’re making. Matching the evidence type to your essay ensures that your arguments are compelling and credible.

Sourcing Credible Evidence

Finding credible sources of evidence is crucial for strengthening your essay. Start with academic journals, reputable news outlets, and books published by experts in the field. These sources provide reliable and well-researched information.

Online databases and libraries are also valuable resources. Look for publications with recent dates to ensure your evidence is current and relevant. The credibility of your essay hinges on the reliability of your sources, so always verify the authority and expertise of the authors.

Using current and reliable evidence not only bolsters your arguments but also demonstrates your commitment to quality and accuracy in your academic work. Remember, the strength of your essay depends significantly on the solidity of your sources.

Integrating Evidence into Your Essay

Effectively incorporating evidence into your essay involves more than just inserting quotes or data. It’s about weaving this evidence seamlessly into your argument. When quoting, use exact words from a source to support specific points, and always provide proper citations. Quoting is powerful, but use it sparingly to avoid over-reliance on others’ words.

Paraphrasing is another technique, where you restate information in your own words. It shows your understanding and keeps the essay in your voice. Summarizing is useful for condensing large pieces of evidence into concise statements, capturing the essence without unnecessary detail.

Remember, each piece of evidence should directly relate to and support your main argument. The goal is to blend your voice with the evidence to create a cohesive and persuasive essay.

Analyzing Evidence

Analyzing evidence in your essay involves more than just presenting facts or quotes; it’s about explaining how this evidence supports your thesis. Start by clearly stating the evidence, then interpret it, linking it directly to your argument. Ask yourself: How does this evidence prove my point? What does it reveal about my topic?

It’s crucial to connect every piece of evidence back to your thesis, the central claim of your essay. This connection demonstrates not just the relevance of the evidence but also its role in advancing your overall argument. By thoroughly analyzing and linking your evidence to your thesis, you strengthen the persuasiveness and coherence of your essay.

Avoiding Common Pitfalls

When using evidence and analysis in essays, common pitfalls include over-reliance on one type of evidence and ignoring counterarguments. Leaning too much on, say, statistical data, while neglecting anecdotal or empirical evidence, can weaken your argument by making it one-dimensional.

To avoid these pitfalls, diversify your sources. Combining different types of evidence creates a well-rounded argument. Also, don’t ignore counterarguments. Addressing them strengthens your essay by showing a comprehensive understanding of the topic.

Seeking examples from the best dissertation writing service can provide a model of how to balance various forms of evidence and counterarguments effectively. Remember, a robust essay acknowledges different perspectives and integrates multiple evidence types to support its thesis.

Using Analysis to Strengthen Your Argument

Thorough analysis is key to enhancing the persuasiveness of your essay. It involves not just presenting evidence, but also critically examining its significance and how it supports your argument. Start by asking probing questions about your evidence: Why is this information relevant? What implications does it have for your argument?

To deepen your analysis, explore the broader context of your evidence. Consider historical, social, or theoretical backgrounds that give your evidence more weight. Additionally, draw connections between different pieces of evidence to show a comprehensive understanding.

By going beyond surface-level examination, your analysis can provide insightful perspectives, making your argument more compelling and thought-provoking. This depth of analysis is what distinguishes a good essay from a great one.

In summary, skillful use of evidence and analysis is crucial in academic essays. Effective integration, diverse sourcing, and careful analysis of evidence strengthen your argument. Avoiding common pitfalls and deepening your analysis enhance your essay’s persuasiveness and credibility.

What this handout is about

This handout will provide a broad overview of gathering and using evidence. It will help you decide what counts as evidence, put evidence to work in your writing, and determine whether you have enough evidence. It will also offer links to additional resources.

Introduction

Many papers that you write in college will require you to make an argument ; this means that you must take a position on the subject you are discussing and support that position with evidence. It’s important that you use the right kind of evidence, that you use it effectively, and that you have an appropriate amount of it. If, for example, your philosophy professor didn’t like it that you used a survey of public opinion as your primary evidence in your ethics paper, you need to find out more about what philosophers count as good evidence. If your instructor has told you that you need more analysis, suggested that you’re “just listing” points or giving a “laundry list,” or asked you how certain points are related to your argument, it may mean that you can do more to fully incorporate your evidence into your argument. Comments like “for example?,” “proof?,” “go deeper,” or “expand” in the margins of your graded paper suggest that you may need more evidence. Let’s take a look at each of these issues—understanding what counts as evidence, using evidence in your argument, and deciding whether you need more evidence.

What counts as evidence?

Before you begin gathering information for possible use as evidence in your argument, you need to be sure that you understand the purpose of your assignment. If you are working on a project for a class, look carefully at the assignment prompt. It may give you clues about what sorts of evidence you will need. Does the instructor mention any particular books you should use in writing your paper or the names of any authors who have written about your topic? How long should your paper be (longer works may require more, or more varied, evidence)? What themes or topics come up in the text of the prompt? Our handout on understanding writing assignments can help you interpret your assignment. It’s also a good idea to think over what has been said about the assignment in class and to talk with your instructor if you need clarification or guidance.

What matters to instructors?

Instructors in different academic fields expect different kinds of arguments and evidence—your chemistry paper might include graphs, charts, statistics, and other quantitative data as evidence, whereas your English paper might include passages from a novel, examples of recurring symbols, or discussions of characterization in the novel. Consider what kinds of sources and evidence you have seen in course readings and lectures. You may wish to see whether the Writing Center has a handout regarding the specific academic field you’re working in—for example, literature , sociology , or history .

What are primary and secondary sources?

A note on terminology: many researchers distinguish between primary and secondary sources of evidence (in this case, “primary” means “first” or “original,” not “most important”). Primary sources include original documents, photographs, interviews, and so forth. Secondary sources present information that has already been processed or interpreted by someone else. For example, if you are writing a paper about the movie “The Matrix,” the movie itself, an interview with the director, and production photos could serve as primary sources of evidence. A movie review from a magazine or a collection of essays about the film would be secondary sources. Depending on the context, the same item could be either a primary or a secondary source: if I am writing about people’s relationships with animals, a collection of stories about animals might be a secondary source; if I am writing about how editors gather diverse stories into collections, the same book might now function as a primary source.

Where can I find evidence?

Here are some examples of sources of information and tips about how to use them in gathering evidence. Ask your instructor if you aren’t sure whether a certain source would be appropriate for your paper.

Print and electronic sources

Books, journals, websites, newspapers, magazines, and documentary films are some of the most common sources of evidence for academic writing. Our handout on evaluating print sources will help you choose your print sources wisely, and the library has a tutorial on evaluating both print sources and websites. A librarian can help you find sources that are appropriate for the type of assignment you are completing. Just visit the reference desk at Davis or the Undergraduate Library or chat with a librarian online (the library’s IM screen name is undergradref).

Observation

Sometimes you can directly observe the thing you are interested in, by watching, listening to, touching, tasting, or smelling it. For example, if you were asked to write about Mozart’s music, you could listen to it; if your topic was how businesses attract traffic, you might go and look at window displays at the mall.

An interview is a good way to collect information that you can’t find through any other type of research. An interview can provide an expert’s opinion, biographical or first-hand experiences, and suggestions for further research.

Surveys allow you to find out some of what a group of people thinks about a topic. Designing an effective survey and interpreting the data you get can be challenging, so it’s a good idea to check with your instructor before creating or administering a survey.

Experiments

Experimental data serve as the primary form of scientific evidence. For scientific experiments, you should follow the specific guidelines of the discipline you are studying. For writing in other fields, more informal experiments might be acceptable as evidence. For example, if you want to prove that food choices in a cafeteria are affected by gender norms, you might ask classmates to undermine those norms on purpose and observe how others react. What would happen if a football player were eating dinner with his teammates and he brought a small salad and diet drink to the table, all the while murmuring about his waistline and wondering how many fat grams the salad dressing contained?

Personal experience

Using your own experiences can be a powerful way to appeal to your readers. You should, however, use personal experience only when it is appropriate to your topic, your writing goals, and your audience. Personal experience should not be your only form of evidence in most papers, and some disciplines frown on using personal experience at all. For example, a story about the microscope you received as a Christmas gift when you were nine years old is probably not applicable to your biology lab report.

Using evidence in an argument

Does evidence speak for itself.

Absolutely not. After you introduce evidence into your writing, you must say why and how this evidence supports your argument. In other words, you have to explain the significance of the evidence and its function in your paper. What turns a fact or piece of information into evidence is the connection it has with a larger claim or argument: evidence is always evidence for or against something, and you have to make that link clear.

As writers, we sometimes assume that our readers already know what we are talking about; we may be wary of elaborating too much because we think the point is obvious. But readers can’t read our minds: although they may be familiar with many of the ideas we are discussing, they don’t know what we are trying to do with those ideas unless we indicate it through explanations, organization, transitions, and so forth. Try to spell out the connections that you were making in your mind when you chose your evidence, decided where to place it in your paper, and drew conclusions based on it. Remember, you can always cut prose from your paper later if you decide that you are stating the obvious.

Here are some questions you can ask yourself about a particular bit of evidence:

• OK, I’ve just stated this point, but so what? Why is it interesting? Why should anyone care?
• What does this information imply?
• What are the consequences of thinking this way or looking at a problem this way?
• I’ve just described what something is like or how I see it, but why is it like that?
• I’ve just said that something happens—so how does it happen? How does it come to be the way it is?
• Why is this information important? Why does it matter?
• How is this idea related to my thesis? What connections exist between them? Does it support my thesis? If so, how does it do that?
• Can I give an example to illustrate this point?

Answering these questions may help you explain how your evidence is related to your overall argument.

How can I incorporate evidence into my paper?

There are many ways to present your evidence. Often, your evidence will be included as text in the body of your paper, as a quotation, paraphrase, or summary. Sometimes you might include graphs, charts, or tables; excerpts from an interview; or photographs or illustrations with accompanying captions.

When you quote, you are reproducing another writer’s words exactly as they appear on the page. Here are some tips to help you decide when to use quotations:

• Quote if you can’t say it any better and the author’s words are particularly brilliant, witty, edgy, distinctive, a good illustration of a point you’re making, or otherwise interesting.
• Quote if you are using a particularly authoritative source and you need the author’s expertise to back up your point.
• Quote if you are analyzing diction, tone, or a writer’s use of a specific word or phrase.
• Quote if you are taking a position that relies on the reader’s understanding exactly what another writer says about the topic.

Be sure to introduce each quotation you use, and always cite your sources. See our handout on quotations for more details on when to quote and how to format quotations.

Like all pieces of evidence, a quotation can’t speak for itself. If you end a paragraph with a quotation, that may be a sign that you have neglected to discuss the importance of the quotation in terms of your argument. It’s important to avoid “plop quotations,” that is, quotations that are just dropped into your paper without any introduction, discussion, or follow-up.

Paraphrasing

When you paraphrase, you take a specific section of a text and put it into your own words. Putting it into your own words doesn’t mean just changing or rearranging a few of the author’s words: to paraphrase well and avoid plagiarism, try setting your source aside and restating the sentence or paragraph you have just read, as though you were describing it to another person. Paraphrasing is different than summary because a paraphrase focuses on a particular, fairly short bit of text (like a phrase, sentence, or paragraph). You’ll need to indicate when you are paraphrasing someone else’s text by citing your source correctly, just as you would with a quotation.

When might you want to paraphrase?

• Paraphrase when you want to introduce a writer’s position, but their original words aren’t special enough to quote.
• Paraphrase when you are supporting a particular point and need to draw on a certain place in a text that supports your point—for example, when one paragraph in a source is especially relevant.
• Paraphrase when you want to present a writer’s view on a topic that differs from your position or that of another writer; you can then refute writer’s specific points in your own words after you paraphrase.
• Paraphrase when you want to comment on a particular example that another writer uses.
• Paraphrase when you need to present information that’s unlikely to be questioned.

When you summarize, you are offering an overview of an entire text, or at least a lengthy section of a text. Summary is useful when you are providing background information, grounding your own argument, or mentioning a source as a counter-argument. A summary is less nuanced than paraphrased material. It can be the most effective way to incorporate a large number of sources when you don’t have a lot of space. When you are summarizing someone else’s argument or ideas, be sure this is clear to the reader and cite your source appropriately.

Statistics, data, charts, graphs, photographs, illustrations

Sometimes the best evidence for your argument is a hard fact or visual representation of a fact. This type of evidence can be a solid backbone for your argument, but you still need to create context for your reader and draw the connections you want them to make. Remember that statistics, data, charts, graph, photographs, and illustrations are all open to interpretation. Guide the reader through the interpretation process. Again, always, cite the origin of your evidence if you didn’t produce the material you are using yourself.

Do I need more evidence?

Let’s say that you’ve identified some appropriate sources, found some evidence, explained to the reader how it fits into your overall argument, incorporated it into your draft effectively, and cited your sources. How do you tell whether you’ve got enough evidence and whether it’s working well in the service of a strong argument or analysis? Here are some techniques you can use to review your draft and assess your use of evidence.

Make a reverse outline

A reverse outline is a great technique for helping you see how each paragraph contributes to proving your thesis. When you make a reverse outline, you record the main ideas in each paragraph in a shorter (outline-like) form so that you can see at a glance what is in your paper. The reverse outline is helpful in at least three ways. First, it lets you see where you have dealt with too many topics in one paragraph (in general, you should have one main idea per paragraph). Second, the reverse outline can help you see where you need more evidence to prove your point or more analysis of that evidence. Third, the reverse outline can help you write your topic sentences: once you have decided what you want each paragraph to be about, you can write topic sentences that explain the topics of the paragraphs and state the relationship of each topic to the overall thesis of the paper.

For tips on making a reverse outline, see our handout on organization .

Color code your paper

You will need three highlighters or colored pencils for this exercise. Use one color to highlight general assertions. These will typically be the topic sentences in your paper. Next, use another color to highlight the specific evidence you provide for each assertion (including quotations, paraphrased or summarized material, statistics, examples, and your own ideas). Lastly, use another color to highlight analysis of your evidence. Which assertions are key to your overall argument? Which ones are especially contestable? How much evidence do you have for each assertion? How much analysis? In general, you should have at least as much analysis as you do evidence, or your paper runs the risk of being more summary than argument. The more controversial an assertion is, the more evidence you may need to provide in order to persuade your reader.

Play devil’s advocate, act like a child, or doubt everything

This technique may be easiest to use with a partner. Ask your friend to take on one of the roles above, then read your paper aloud to them. After each section, pause and let your friend interrogate you. If your friend is playing devil’s advocate, they will always take the opposing viewpoint and force you to keep defending yourself. If your friend is acting like a child, they will question every sentence, even seemingly self-explanatory ones. If your friend is a doubter, they won’t believe anything you say. Justifying your position verbally or explaining yourself will force you to strengthen the evidence in your paper. If you already have enough evidence but haven’t connected it clearly enough to your main argument, explaining to your friend how the evidence is relevant or what it proves may help you to do so.

Developing Deeper Analysis & Insights

Analysis is a central writing skill in academic writing. Essentially, analysis is what writers do with evidence to make meaning of it. While there are specific disciplinary types of analysis (e.g., rhetorical, discourse, close reading, etc.), most analysis involves zooming into evidence to understand how the specific parts work and how their specific function might relate to a larger whole. That is, we usually need to zoom into the details and then reflect on the larger picture. In this writing guide, we cover analysis basics briefly and then offer some strategies for deepening your analysis. Deepening your analysis means pushing your thinking further, developing a more insightful and interesting answer to the “so what?” question, and elevating your writing.

Analysis Basics

Questions to Ask of the Text:

• Is the evidence fully explained and contextualized? Where in the text/story does this evidence come from (briefly)? What do you think the literal meaning of the quote/evidence is and why? Why did you select this particular evidence?
• Are you selecting a long enough quote to work with and analyze? While over-quoting can be a problem, so too can under-quoting.
• Do you connect each piece of evidence explicitly to the claim or focus of the paper?

Strategies & Explanation

• Sometimes turning the focus of the paper into a question can really help someone to figure out how to work with evidence. All evidence should answer the question--the work of analysis is explaining how it answers the question.
• The goal of evidence in analytical writing is not just to prove that X exists or is true, but rather to show something interesting about it--to push ideas forward, to offer insights about a quote. To do this, sometimes having a full sentence for a quote helps--if a writer is only using single-word quotes, for example, they may struggle to make meaning out of it.

Deepening Analysis

Not all of these strategies work every time, but usually employing one of them is enough to really help elevate the ideas and intellectual work of a paper:

• Bring the very best point in each paragraph into the topic sentence. Often these sentences are at the very end of a paragraph in a solid draft. When you bring it to the front of the paragraph, you then need to read the paragraph with the new topic sentence and reflect on: what else can we say about this evidence? What else can it show us about your claim?
• Complicate the point by adding contrasting information, a different perspective, or by naming something that doesn’t fit. Often we’re taught that evidence needs to prove our thesis. But, richer ideas emerge from conflict, from difference, from complications. In a compare and contrast essay, this point is very easy to see--we get somewhere further when we consider how two things are different. In an analysis of a single text, we might look at a single piece of evidence and consider: how could this choice the writer made here be different? What other choices could the writer have made and why didn’t they? Sometimes naming what isn’t in the text can help emphasize the importance of a particular choice.
• Shift the focus question of the essay and ask the new question of each piece of evidence. For example, a student is looking at examples of language discrimination (their evidence) in order to make an argument that answers the question: what is language discrimination? Questions that are definitional (what is X? How does Y work? What is the problem here?) can make deeper analysis challenging. It’s tempting to simply say the equivalent of “Here is another example of language discrimination.” However, a strategy to help with this is to shift the question a little bit. So perhaps the paragraphs start by naming different instances of language discrimination, but the analysis then tackles questions like: what are the effects of language discrimination? Why is language discrimination so problematic in these cases? Who perpetuates language discrimination and how? In a paper like this, it’s unlikely you can answer all of those questions--but, selecting ONE shifted version of a question that each paragraph can answer, too, helps deepen the analysis and keeps the essay focused.
• Examine perspective--both the writer’s and those of others involved with the issue. You might reflect on your own perspectives as a unique audience/reader. For example, what is illuminated when you read this essay as an engineer? As a person of color? As a first-generation student at Cornell? As an economically privileged person? As a deeply religious Christian? In order to add perspective into the analysis, the writer has to name these perspectives with phrases like: As a religious undergraduate student, I understand X to mean… And then, try to explain how the specificity of your perspective illuminates a different reading or understanding of a term, point, or evidence. You can do this same move by reflecting on who the intended audience of a text is versus who else might be reading it--how does it affect different audiences differently? Might that be relevant to the analysis?
• Qualify claims and/or acknowledge limitations. Before college level writing and often in the media, there is a belief that qualifications and/or acknowledging the limitations of a point adds weakness to an argument. However, this actually adds depth, honesty, and nuance to ideas. It allows you to develop more thoughtful and more accurate ideas. The questions to ask to help foster this include: Is this always true? When is it not true? What else might complicate what you’ve said? Can we add nuance to this idea to make it more accurate? Qualifications involve words like: sometimes, may effect, often, in some cases, etc. These terms are not weak or to be avoided, they actually add accuracy and nuance.

Much of how to use evidence is about finding a clear and logical relation between the evidence you use and your claim. For example, if you are asked to write a paper on the effects of pollution on watersheds, you would not use a story your grandfather told you about the river he used to swim in that is now polluted. You would look for peer-reviewed journal articles by experts on the subject.

Once you have found the appropriate type of evidence, it is important to select the evidence that supports your specific claim. For example, if you are writing a psychology paper on the role of emotions in decision-making, you would look for psychology journal articles that connect these two elements.

For example:

By referencing the study in the first example and supplying textual evidence in the second, the initial statement in the paragraph moves from opinion to supported argument; however, you must still analyze your evidence.

Once you have selected your evidence it is important to tell you reader why the evidence supports your claim. Evidence does not speak for itself: some readers may draw different conclusions from your evidence, or may not understand the relation between your evidence and your claim. It is up to you to walk your reader through the significance of the evidence to your claim and your larger argument. In short, you need a reason why the evidence supports the claim – you need to analyze the evidence.

Some questions you could consider are:

• Why is this evidence interesting or effective?
• What are the consequences or implications of this evidence?
• Why is this information important?
• How has it been important to my paper or to the field I am studying?
• How is this idea related to my thesis?
• This evidence points to a result of an experiment or study, can I explain why these results are important or what caused them?
• Can I give an example to illustrate this point?
• What are the strengths and weaknesses of the evidence presented?

If we look to our first examples, they may look like this once we add analysis to our evidence:

• Emotions play a larger role in rational decision-making than most us think ( claim ). Subjects deciding to wear a seatbelt demonstrated an activity in the ventromedial frontal lobe, the part of the brain that governs emotion (Shibata 2001) ( evidence ). This suggests that people making rational decisions, even when performing naturalized tasks such as putting on a seatbelt, rely on their emotions ( analysis ).

Or, when we look at the example of Dr. Jekyll and Mr. Hyde:

• The physical descriptions of the laboratory and the main house, in Dr Jekyll and Mr. Hyde, metaphorically point to the gothic elements in the novel ( claim ). The main house had "a great air of wealth and comfort" (13), while the laboratory door "which was equipped with neither bell nor knocker, was blistered and distained" (3) ( evidence ). The comforting and welcoming look of the main house is in sharp contrast to the door of the laboratory, which does not even have a bell to invite people in. The laboratory door is eerie and gothic highlighting the abnormal and mystical events that take place behind it ( analysis ).
