Faulty analogies

Categories: Psychology & Philosophy

In the following weeks I’ll be doing an exploration of several logical fallacies and errors of thinking. I’m returning to this area because it is a difficult one to recall a taxonomy of categorised fallacies and errors. There are some 300-plus logical fallacies on record. Most people cannot name one. What’s the importance of this?


In the intricate tapestry of human discourse, where ideas weave through the loom of dialogue, the significance of avoiding logical fallacies emerges as a guiding principle, illuminating the path to clarity and understanding. Logical fallacies, those deceptive sirens of reasoning, lure unsuspecting minds into the murky waters of flawed argumentation, where the truth becomes obscured by the fog of error.

To navigate the complex seas of thought, one must be vigilant against these fallacies, for they are not mere academic trivialities but pivotal determinants in the quest for sound reasoning and effective communication. In politics, for instance, the reliance on fallacious arguments can mislead public opinion, shaping policies on foundations as unstable as sand. In science and academia, fallacies can derail the pursuit of knowledge, leading bright minds astray. Even in the personal realm, fallacies can cloud judgment, impair decision-making, and fracture relationships.

Consider the tapestry again – a fabric representing the collective understanding. Each thread is an idea, each colour a perspective. Logical fallacies, when woven into this fabric, create distortions and weaknesses. They are the misplaced threads that disrupt the pattern, the erroneous colours that distort the picture. By avoiding these fallacies, the weaver – the thinker, the speaker, the writer – ensures that the tapestry retains its integrity, its strength, and its beauty.

Moreover, in the pursuit of truth – that elusive and noble quest – the avoidance of fallacies is akin to holding a lantern high in the darkness. Fallacies obscure truth, muddling it with error and misconception. To sidestep them is to clear the path, allowing the light of truth to shine forth, undimmed and unobscured.

In essence, the avoidance of logical fallacies is not just an academic exercise; it is a commitment to intellectual honesty, a dedication to the purity of thought and expression. It is about crafting arguments that stand not on the brittle stilts of deception but on the solid ground of rationality. It is, in its deepest sense, a respect for the power of reason and a tribute to the quest for truth that lies at the heart of all human endeavour.

Description of faulty analogy

Faulty analogy, categorised under the broader classification of ‘Informal Fallacies’ in logical argumentation, involves comparing two things that are not sufficiently alike in relevant aspects, leading to a flawed conclusion based on their perceived similarities. This fallacy falls under the sub-category of False Analogy, which is itself a sub-fallacy of Faulty Comparison. Here are some examples demonstrating the use of faulty analogy:

  1. Technological Progress and Social Progress:
    • Fallacy Category: Faulty Analogy
    • Example: “Just as technology advances rapidly, improving every year, so too should social systems progress at the same rate. If our phones and computers can evolve so quickly, there’s no reason our social policies can’t.
    • Flaw: This analogy incorrectly equates technological progress, which is based on scientific and engineering advancements, with social progress, which involves complex human behaviour, cultural norms, and political systems. The factors driving change in these areas are vastly different, making the comparison misleading.
  2. Education and Manufacturing Processes:
    • Fallacy Category: Faulty Analogy
    • Example: “Educating a child is like manufacturing a car. If you have a good blueprint and follow it precisely, you’ll produce a high-quality product every time.
    • Flaw: This analogy incorrectly compares the process of education, a dynamic and individualised process, with industrial manufacturing, which is standardised and mechanical. It fails to account for the unique and variable nature of human learning, development, and individual differences.
  3. Running a Business and Running a Government:
    • Fallacy Category: Faulty Analogy
    • Example: “Running a government is just like running a business; if you can successfully run a large corporation, you can run a country efficiently.
    • Flaw: This analogy oversimplifies the complexities of governance. While there are some similarities in management skills, a government has responsibilities like public welfare, diplomacy, and social justice, which are not typically concerns of a business. The objectives, stakeholders, and accountability measures in government are fundamentally different from those in business.
  4. Physical Health and Economic Health:
    • Fallacy Category: Faulty Analogy
    • Example: “Just as a person must reduce their calorie intake to lose weight, a government should reduce its spending to improve the economy.
    • Flaw: This analogy simplistically compares a biological process with complex economic systems. While budget cuts are a tool in economic policy, the health of an economy depends on a myriad of factors such as investment, consumer confidence, and global market trends, making the comparison with personal dieting overly simplistic and misleading.

These examples illustrate how faulty analogies can lead to oversimplified or incorrect conclusions by drawing parallels between things that are fundamentally dissimilar in crucial respects.

Self-serving nature

Erroneously chosen or faulty analogies can often be self-serving, particularly when they are used strategically to persuade or convince an audience in argumentation. This self-serving aspect can manifest in several ways:

  1. Supporting a Preconceived Conclusion: Faulty analogies are often selected because they superficially appear to support a conclusion the arguer wishes to promote. By drawing an analogy that seems to parallel their viewpoint, the arguer aims to strengthen their position, even if the analogy is not logically sound.
  2. Simplifying Complex Issues: Complex issues are often challenging to understand and communicate. A self-serving use of analogy might oversimplify these complexities, making an argument more palatable or convincing to an audience that may not have the expertise or inclination to understand the nuanced reality.
  3. Manipulating Emotional Responses: Analogies can evoke emotional responses. A carefully chosen analogy might play on the audience’s fears, hopes, or values, swaying their opinions irrespective of the logical strength of the argument. This can be particularly self-serving when the analogy is designed to provoke a strong emotional reaction that clouds rational judgment.
  4. Shifting Focus: Sometimes, a faulty analogy is used to divert attention from the real issues at hand. By drawing a parallel with a different, often less controversial, topic, the arguer can shift the focus of the discussion to a more comfortable or advantageous ground.
  5. Creating False Equivalencies: Self-serving analogies may create a sense of false equivalence between two scenarios, leading audiences to perceive them as more similar than they actually are. This can be used to justify or rationalise certain actions or policies by likening them to others that are more widely accepted or less controversial.

In summary, while analogies can be powerful tools for explanation and argumentation, they can also be misused in a self-serving manner, either intentionally or unintentionally, leading to flawed reasoning or deceptive persuasion. The critical evaluation of analogies for relevance, similarity, and logical coherence is crucial in discerning the validity of arguments.

Other motivations

there are various motivations beyond simplification and self-serving tendencies that can drive the use of faulty analogies in argumentation:

  1. Ignorance or Misunderstanding: Sometimes, faulty analogies arise from a genuine lack of understanding or misinformation about the subjects being compared. The person using the analogy might not be aware of the crucial differences that render the analogy inappropriate.
  2. Persuasion and Rhetoric: Analogies are powerful rhetorical tools. A speaker might use a faulty analogy intentionally to persuade or influence an audience, relying on the surface appeal of the comparison rather than its logical validity.
  3. Emotional Appeal: Some analogies are crafted to evoke emotional responses. They might be used to appeal to the audience’s fears, hopes, or values, even if the analogy itself is logically flawed. This can be particularly effective in swaying public opinion or in advertising.
  4. Conveying Complexity: In attempting to explain complex ideas or phenomena, individuals might resort to analogies that are accessible but not entirely accurate. The intention here is to make the complex understandable, even at the expense of precision.
  5. Ideological Alignment: Faulty analogies can be employed to align a particular argument with broader ideological beliefs or narratives. By drawing parallels with widely accepted or popular ideas, the arguer can lend apparent legitimacy to their position.
  6. Deflecting Criticism or Responsibility: In some cases, analogies are used to deflect criticism or responsibility away from oneself or one’s group. By comparing a situation to another that is perceived more favorably or less critically, the individual can attempt to minimise the perceived severity or responsibility of the first situation.
  7. Confirmation Bias: People often use analogies that confirm their existing beliefs or biases, even if these analogies are flawed. This is particularly common in polarised debates, where each side uses analogies that support their viewpoint.
  8. Lack of Better Arguments: Sometimes, a faulty analogy is the best argument someone can come up with, either due to a lack of information, time, or ability to construct a more robust argument.

In summary, the motivations for using faulty analogies are multifaceted, ranging from innocent errors and attempts to clarify complex issues, to strategic efforts to persuade, align with ideologies, evoke emotional responses, or deflect criticism. Recognising these motivations can aid in critically evaluating the use and validity of analogies in discourse.

Doomed by simplification

The tendency to simplify complex situations is a common aspect of human cognition and communication. This inclination can be attributed to several factors:

  1. Cognitive Ease: Complex situations often involve numerous variables, uncertainties, and abstract concepts, which can be cognitively demanding to process. Simplification helps in reducing cognitive load, making it easier for individuals to understand and discuss these situations.
  2. Communication Efficiency: Simplifying complex ideas is also a practical tool for communication. It allows the essence of a situation to be conveyed quickly and in an accessible manner, especially to audiences who may not have the background or expertise to grasp the full complexity.
  3. Heuristic Thinking: Humans frequently rely on heuristics, or mental shortcuts, to make sense of complex information. While heuristics can be helpful in making quick judgments, they can also lead to oversimplification and errors in reasoning.
  4. Desire for Certainty and Control: Complexity often brings with it a sense of uncertainty and unpredictability. Simplification can create an illusion of certainty and control, which is psychologically comforting. It helps people feel more confident about their understanding of a situation and their decisions regarding it.
  5. Narrative and Storytelling: Humans have a natural affinity for narratives and storytelling. Simplifying complex situations into a narrative format with clear characters, motives, and outcomes makes them more relatable and memorable.
  6. Confirmation Bias: People tend to favour information that confirms their pre-existing beliefs or hypotheses. Simplification can sometimes involve selectively focusing on certain aspects of a situation while ignoring others, which can align with and reinforce existing beliefs or viewpoints.

While simplification can be beneficial for understanding and communication, it is important to be aware of its limitations. Over-simplification can lead to misconceptions, faulty decisions, and a lack of appreciation for the nuances and complexities inherent in many situations. Critical thinking, a willingness to engage with complexity, and an awareness of one’s own cognitive biases are essential for a balanced understanding of complex issues.
