In today's information-saturated world, we're constantly bombarded with data, statistics, and claims from various sources. Unfortunately, a significant portion of this information is misleading, exaggerated, or outright false – in other words, bullshit. Carl T. Bergstrom's book "Calling Bullshit" aims to equip readers with the tools and knowledge necessary to identify, understand, and combat the pervasive spread of misinformation in our data-driven society.
Introduction: The Bullshit Crisis
We live in an era where information is more accessible than ever before. However, this abundance of data has also led to an unprecedented proliferation of bullshit. From sensationalized news headlines to misleading scientific studies, bullshit has become a significant problem that affects our decision-making, beliefs, and even public policy.
Bergstrom argues that we all have a responsibility to become more discerning consumers of information and to actively challenge the bullshit we encounter. This book serves as a guide to help readers develop critical thinking skills and become better equipped to navigate the complex landscape of modern information.
Understanding Bullshit
What is Bullshit?
Bullshit, as defined by Bergstrom, is not simply lying or making false statements. Instead, it's a form of persuasion that aims to convince people of something without regard for its truthfulness. Bullshitters are more concerned with winning arguments or impressing their audience than with presenting accurate information.
In the modern context, bullshit often masquerades as scientific or data-driven truth. It employs sophisticated language, complex statistics, and impressive visuals to overwhelm the audience and make its claims seem credible.
The Tools of the Modern Bullshitter
Modern bullshitters have several powerful tools at their disposal:
Language: Using jargon, technical terms, and complex sentence structures to confuse or impress the audience.
Statistics: Manipulating numbers and data to support their claims, often by presenting them out of context or using misleading comparisons.
Graphics: Creating visually appealing charts, graphs, and infographics that can distort or misrepresent data.
Information overload: Bombarding the audience with an overwhelming amount of information, making it difficult to discern what's relevant or true.
The Black Box Phenomenon
One common tactic used by bullshitters is the "black box" approach. This involves feeding data into a complex process or algorithm (the black box) and presenting the output as objective fact. By obscuring the inner workings of the process, bullshitters make it difficult for others to critique or question their methods.
For example, a study claiming to prove that criminals have differently shaped heads from non-criminals used an algorithm to analyze facial features. However, the study's fundamental flaw lay in its data collection: the photos of criminals were government-issued ID photos, while non-criminals were represented by professional headshots. This discrepancy in the input data rendered the entire study meaningless, regardless of the sophistication of the algorithm used.
Common Types of Bullshit
Correlation vs. Causation
One of the most prevalent forms of bullshit in scientific and statistical claims is the confusion between correlation and causation. Just because two things are related doesn't mean that one causes the other.
For instance, a study showing a correlation between rising house prices and lower fertility rates among women in their late twenties doesn't necessarily mean that expensive housing causes fewer births. There could be underlying factors affecting both trends, or the relationship could be purely coincidental.
Media outlets often exacerbate this problem by reporting on correlational studies with causal language, leading to misleading headlines and public misunderstanding.
Misleading Numbers and Percentages
Numbers can be easily manipulated to create a false impression of significance or insignificance. For example, claiming that a product is "99.9% caffeine-free" sounds impressive until you realize that regular coffee is also about 99.9% caffeine-free by volume.
Another common tactic is to present raw numbers without context. Stating that 2,139 people with DACA status have been convicted or accused of crimes sounds alarming until you realize it's out of a total population of 700,000 – less than 0.3%.
Percentage increases can also be misleading. A 0.5% increase in the risk of developing an alcohol-related health problem sounds significant, but if the baseline risk is only 1%, the actual increase is from 1% to 1.005% – a much less dramatic change.
Selection Bias
Selection bias occurs when the data used for a study or statistic isn't representative of the entire population. This can lead to skewed results and false conclusions.
For example, surveying people at an organic market about their political views would likely result in a disproportionately liberal sample, not representative of the general population.
In clinical trials, selection bias can occur when participants drop out of studies due to side effects, leading to an underrepresentation of negative outcomes in the final results.
Big Data and Machine Learning Pitfalls
While big data and machine learning have great potential, they're not immune to bullshit. In fact, the complexity and opacity of these technologies can sometimes make it easier for bullshit to slip through unnoticed.
One example is an algorithm designed to identify heart and lung issues from chest X-rays. The machine appeared to perform well but was actually basing its decisions on text printed in the corner of the images, which indicated which machine had taken the scan. When tested on a different set of X-rays, the algorithm failed completely.
Another case is Google Flu Trends, which aimed to predict flu outbreaks based on search terms. The algorithm initially seemed successful but began to fail over time because it relied on correlations (like searches for "high school basketball") that weren't causally related to flu outbreaks.
The Imperfections of Modern Science
While science is often viewed as a bastion of truth and objectivity, the reality is that the scientific process is imperfect and susceptible to bullshit.
Publication Bias
Scientific journals tend to favor studies with positive results, leading to a skewed representation of research findings. Studies that fail to find significant results often go unpublished, creating a false impression of the state of knowledge in a field.
P-Hacking and Statistical Manipulation
The standard threshold for statistical significance (p < 0.05) has led to a phenomenon known as p-hacking. Researchers may manipulate their data or analysis methods to achieve this threshold, even if the underlying relationship isn't meaningful.
Media Reporting
Only a small fraction of scientific research gets reported in the media, and studies with sensational or counterintuitive findings are more likely to make headlines. This creates a distorted view of scientific progress and can lead to public misunderstanding of complex issues.
Predatory Journals
Less reputable scientific journals may publish studies with little to no peer review, as long as the authors are willing to pay. This has led to a proliferation of low-quality or fraudulent research being published under the guise of legitimate science.
Strategies for Identifying and Combating Bullshit
Ask Key Questions
When evaluating information, ask three key questions:
- Who is behind this information?
- How did they obtain it?
- What are they trying to sell or promote?
These questions can help uncover potential biases or hidden agendas behind the information being presented.
Use Common Sense and Plausibility Checks
If something seems too good (or bad) to be true, it probably is. Trust your instincts and apply basic logic to evaluate claims.
Make Fermi Estimations
Named after physicist Enrico Fermi, these are rough calculations you can do in your head to estimate the plausibility of a claim. For example, if someone claims there are 121,000 people named John Smith in the UK, you can quickly estimate that the real number is likely much lower based on the country's population and the frequency of those names.
Be Aware of Confirmation Bias
We all tend to believe information that confirms our existing beliefs. Be extra cautious when evaluating information that aligns with your preconceptions, as it may be bullshit that you're more likely to accept uncritically.
Remember Correlation vs. Causation
Always be skeptical of claims that one trend or event has "caused" another. Look for alternative explanations or underlying factors that could explain the relationship.
Be Cautious with Online Sources
Information spread through social media and unreliable online sources is more likely to be bullshit. Always verify claims from multiple reputable sources before accepting them as true.
Call Out Bullshit Respectfully
When you identify bullshit, it's important to call it out. However, do so politely and respectfully. Remember that everyone makes mistakes, and you're more likely to change someone's mind if you approach the situation with kindness and understanding.
The Importance of Scientific Literacy
To effectively combat bullshit, it's crucial to develop a basic understanding of scientific principles and statistical concepts. This doesn't mean you need to become an expert in every field, but having a foundational knowledge can help you critically evaluate claims and identify potential red flags.
Understanding Statistical Significance
Learn the basics of statistical significance and what p-values really mean. Understand that a statistically significant result doesn't necessarily imply practical significance or a large effect size.
Recognizing Study Limitations
When reading about scientific studies, pay attention to the methodology, sample size, and potential limitations. Be wary of studies with small sample sizes or those that haven't been replicated.
Understanding Margins of Error
In surveys and polls, always consider the margin of error. A small lead in a political poll may not be meaningful if it falls within the margin of error.
Recognizing the Importance of Context
Numbers and statistics are meaningless without proper context. Always look for comparisons, baselines, and historical trends to put the information into perspective.
The Role of Media Literacy
In addition to scientific literacy, developing media literacy skills is essential for navigating the modern information landscape.
Identifying Reliable Sources
Learn to distinguish between reputable news sources and those with a history of sensationalism or bias. Look for articles that cite primary sources and provide balanced perspectives.
Understanding Headlines vs. Content
Headlines are often designed to grab attention and may not accurately reflect the nuance of the full article. Always read beyond the headline to get a complete understanding of the story.
Recognizing Native Advertising and Sponsored Content
Be aware that some content that appears to be editorial may actually be paid advertising. Look for disclosures and be skeptical of overly positive product reviews or brand mentions.
Fact-Checking and Cross-Referencing
When you encounter a surprising or controversial claim, take the time to fact-check it using multiple reliable sources. Don't rely on a single article or social media post for important information.
The Ethics of Calling Bullshit
While it's important to identify and call out bullshit, it's equally important to do so ethically and responsibly.
Avoid Becoming a Bullshitter Yourself
In your eagerness to debunk false claims, be careful not to fall into the trap of exaggeration or misrepresentation. Always strive for accuracy and honesty in your own arguments.
Acknowledge Uncertainty
Recognize that many issues are complex and nuanced. It's okay to admit when you're not sure about something or when more research is needed to draw definitive conclusions.
Be Open to Changing Your Mind
If presented with compelling evidence that contradicts your beliefs, be willing to reconsider your position. Intellectual honesty and flexibility are crucial in the fight against bullshit.
Promote Constructive Dialogue
When calling out bullshit, aim to educate rather than humiliate. Engage in respectful discussions and provide resources for further learning.
The Future of Bullshit
As technology continues to advance, new forms of bullshit are likely to emerge. Deepfake videos, AI-generated text, and increasingly sophisticated data manipulation techniques will present new challenges in distinguishing fact from fiction.
Staying Ahead of Technological Advances
Keep yourself informed about emerging technologies and their potential for misuse. Stay updated on tools and techniques for identifying manipulated media and AI-generated content.
Supporting Quality Journalism and Research
Advocate for and support high-quality, fact-based journalism and scientific research. Consider subscribing to reputable news sources and supporting organizations dedicated to promoting truth and accuracy in media.
Promoting Digital Literacy Education
Advocate for the inclusion of digital literacy and critical thinking skills in educational curricula. These skills are essential for future generations to navigate an increasingly complex information landscape.
