Knowing How You Know
How do you decide what to believe? How do you distinguish between fact and opinion? When you hear a claim, how do you assess the reliability of the sources? What do you consider to be a reliable rather than an unreliable information source? How do you gather and assess evidence for or against some proposition? If some trusted authority supports a particular belief and direct evidence you see disputes that belief, how do you resolve this discrepancy? Are your beliefs well-founded and consistent? What would cause you to change a belief?
This course will help you explore these questions and develop your own well-considered rules for deciding what to believe. These rules are called your theory of knowledge, and when you have developed your own theory of knowledge you will finally know how you know.
The objectives of this course are:
- Examine how you decide what you believe,
- Explore the range of more reliable and less reliable information sources,
- Explore the tyranny of evidence,
- Survey example theories of knowledge,
- Develop your own Theory of Knowledge,
- Test and refine your Theory of Knowledge,
- Apply your Theory of Knowledge to improve the accuracy and consistency of your beliefs, and
- Align your beliefs with reality.
There are no specific prerequisites to this course; all students are welcome. Students may benefit from completing the course Facing Facts before beginning this course.

Deciding what to Believe
How do you decide what to believe? Many people believe whatever they want to as they select information that seems to confirm what is convenient for them to believe and dismiss contrary or conflicting information. Other people listen to what their friends have to say, or follow the opinions of various celebrities. It might be that the group that shouts the loudest or most often or most cleverly gets your attention. Perhaps you are influenced by people in power, listening to what parents and teachers said when you were young, rebelling against them as an adolescent, and then choosing other authority figures to follow as an adult. People are often captivated by attractive, charming, glib, or charismatic people. Mystical language seems to seduce and entrance others. Many of us are members of some tribe which supports its own belief system. This might be a political party, an advocacy group, a professional society or industry group, a club, religious or cultural traditions, or proponents of some ideology.
None of these approaches can accurately distinguish reliable information from rumor, myth, gossip, advertisement, propaganda, or other forms of unreliable, outdated, misleading, untrue, or deceptive misinformation. Also, because we are most comfortable when we are most certain, regardless of the validity of our beliefs, we naturally avoid or resist exposure to information that threatens our own tenuous certainty.
The Supreme Court broadly upholds the first amendment protection of free speech. Hate speech, misleading information, and deliberate lies are all constitutionally protected forms of expression. The Internet welcomes all contributors and as a result support for almost any belief, regardless of its truth, is easily found. This constant influx of unverified information makes it essential that we take personal responsibility to decide for ourselves what is reliable and what is not.
“You're entitled to your own opinions”, Senator Daniel Patrick Moynihan declares, “but you're not entitled to your own facts.” This succinctly captures the extent and boundaries of tolerance. While tolerance is essential in the realm of opinion, it has no place in the realm of fact. Of course you need to be able to distinguish fact from opinion to be tolerant.
Facts correspond with reality. Because we all live on the same earth, we all share the same reality, observed through our unique points of view. This is our common ground, we need to dig deeply to find that common ground and stand together on the bedrock of reality. Facts establish the middle ground. We can each choose to move toward the political left or the right, but we each must start from the facts while we constantly stay connected to the facts.
Taking responsibility for your own beliefs is not easy, but it is immensely rewarding. When you know how you know, you can be confident in what you know. You can then strive to purify the knowledge stream you accumulate and assimilate. When you know how you know you can easily identify the fools, fakers, and frauds among us, and confidently dispute, correct, dismiss, or avoid them.
Knowing how you know is a big step you can take now to reduce the influence of money and special interests in politics. Because you are less susceptible to misleading, manipulative, deceptive, and unhelpful influences, money spent by special interests on propaganda designed to support only their cause becomes less effective. You know how to make up your own mind based on a careful, accurate, nuanced, and balanced assessment of reliable information. Facts are stubborn. When you are justifiably confident in knowing what is true, what is false, and what you are unsure of you know when to stand firm, when to yield, and when to change your beliefs.
Your beliefs are what you accept as being true. This assignment begins to examine your beliefs.
- Write down a few of your own beliefs. Choose a range of more widely accepted and less widely accepted beliefs.
- For each of these beliefs, write down how you decided it is true.
- Optionally read this essay on the nature of beliefs.
- Optionally read this Wikipedia article on beliefs.
- Look at the checkered diagram on the right.
- Do you believe the horizontal lines are straight and parallel or do you believe they are tilted to the right or the left?
- Now look at the array from the side or use a straight edge or ruler to examine and measure the horizontal lines. It may be helpful to double click on the figure to examine a larger rendering of the image. You may find it best to print out the image and examine the hard copy rendering of it. Focus on the image one square at a time. Can you see the horizontal lines bend at any point? Do the horizontal lines seem parallel or tilted when you analyze them objectively?
- Based on what you learned in #3 above, look again at the figure. Do you now believe them to be parallel or tilted?
- Do you have more confidence in your conception of the figure or your perception of it?
- View the video: Why you think you're right — even if you're wrong, Julia Galef, TED Talk, February 2016
- As you go through your daily activities, notice if you are behaving as a soldier and defending your current beliefs, or if you are acting as a scout and exploring, expanding your experiences, and challenging your beliefs. What mindset is serving you best in each instance?
What is a Theory of Knowledge?
Our world is full of various stimuli that contend for our attention and masquerade as the truth. Unfortunately much of the information we are exposed to is unreliable and misleading. The diagram on the right illustrates our need to filter the raw stimuli we are exposed to in the world to arrive at our own beliefs. Our theory of knowledge is the process we use to analyze and integrate raw information sources into our beliefs about what is true, what is false, what we are unsure of, and what we are unaware of.
Your theory of knowledge is the set of rules you follow to decide what to believe. Since you have chosen your beliefs, you must have some theory of knowledge in some form, however it is unlikely you have given it much thought, written it down, tested it, refined it, or applied it conscientiously to evaluating your own beliefs.
- Select 3 information sources from the following list to study.
- News, opinions, analysis, commentary, satire, testimonials, endorsements, threats, conversations, dialogue, rumors, gossip, folk lore, traditions, rules, superstitions, taboos, censorship, speculation, predictions, fear mongering, forecasts, propaganda, advertisement, sales pitches, advocacy, political talking points, religious dogma, scriptures, prophesies, ideology, text books, school lessons, numbers, data, statistics, lobbying efforts, reports, street lore, peer pressure, web pages, Facebook, twitter, hearsay, disinformation, stories, anecdotes, legends, fables, myths, allegories, intuition, feelings, premonitions, origin stories, archetypes, suppositions, fallacies, red herrings, authorities, experts, celebrities, councilors, mystics, clairvoyants, charlatans, fools, fakers, and frauds all contend for our attention and opportunities to exert their influence.
- For each of the sources chosen, identify why they may be influential, why they are memorable, why they seem credible, and why they may be misleading or untrue.
- Identify some belief you have accepted as true based on each of the sources studied above.
Matters of Fact
Distinguishing among: 1) matters of fact, 2) matters of preference, or 3) matters of controversy is an essential skill in knowing how you know. Statements can be classified as one of the following three types:
- Matters of fact. These statements can be assessed and verified through the correct use of evidence gathering, and reasoning. A correct statement can be made with conviction. These statements declare “what is” and careful researchers agree on the answer. Examples include: The boiling point of water is 100° Centigrade, gold is denser than lead, and the movie Spotlight won Best Picture in 2016. Notice the use of “is” to convey certainty in these statements. These matters of fact are the targets of your theory of knowledge. A reliable theory of knowledge will describe how to effectively research factual claims, how to identify and use reliable sources, and how to resolve disputed or contradictory factual claims. The principle of consilience will ensure that reliably researched facts will converge toward the actual reality.
- Matters of taste, preference, or opinion. Any claim is acceptable here, because the statement depends only on the preferences of the person making it. Examples include: I feel that purple is the most beautiful color, I prefer chocolate ice-cream to vanilla ice-cream, and I believe that Rembrandt was a better artist than Picasso. Notice the use of “prefer”, “feel”, and “believe” to convey a personal preference. These matters of preference fall outside your theory of knowledge. Just enjoy them.
- Matters of controversy. Although these are not opinions, sincere experts often disagree on the best answer or the best course of action. These statements propose “what ought to be” or they ask about a topic that is not yet fully and carefully explored or researched. Examples include: I believe the most pressing problem facing the world today is the lack of clean safe drinking water for all people, I think the best approach to reducing gun violence is to require comprehensive background checks for all gun purchases, and I believe incarceration rates are too high in the US. Notice the use of “believe” and “think” to convey personal positions here. Although it is instructive to learn more about matters of controversy by exploring them with dialogue and Socratic Methods, they lie outside of your theory of knowledge.
- Read this essay on the Height of the Eiffel Tower.
- Read over this list of questions to classify.
- Identify at least five of these questions in each of the following classifications: 1) matters of fact, 2) matters of preference, or 3) matters of controversy.
- Consider the role the principle of consilience will play in your own theory of knowledge.
The Unity of Knowledge
Because we all live on the same earth, in the same universe, reliable knowledge about our world must converge toward a consistent description of that world. Each phenomenon we observe must fit into a single coherent and integrated description of our universe. Because we all live in the same universe, as we continue to examine our universe more and more closely, we can agree on a larger set of facts about our universe. Reliable epistemologies—ways of knowing—increase our shared common knowledge.
- Browse this emergence diagram.
- Read this essay on our one world.
- Please consider your position regarding the unity of knowledge.
- Do you believe that although each person has their own unique life experiences and unique point of view, we are all experiencing the same world, and there are facts that describe our world that we can all agree on? In other words, referring to the allegory of the blind men and an elephant, each of us is experiencing some aspects of the same elephant. Furthermore, the Eiffel tower does have a particular height.
- Or do you believe that each of us experiences our own world, their is a different world for each of us and there are not facts that are common among that multiplicity of worlds? Each of us is experiencing a different elephant. Furthermore, the height of the Eiffel tower depends on who is asked about it, and how they are feeling at the moment.
- Consider how your theory of knowledge will address the unity of knowledge. When new information comes to your attention that is inconsistent with a coherent description of the universe, will you: 1) dismiss that new information, 2) modify your present description of the universe to accommodate that new information, or 3) tolerate inconsistencies?
Please complete the module on Examining Ideologies along with the associated assignments.
Beware of Friendly Persuasion
We evolved to trust what friends tell us. Today we have many communications with people who are acquaintances we hardly know. It is wise to verify hearsay by checking facts with reliable sources.
- Fact check rumors before repeating them, or assimilating them into your knowledge base.
- Read the essay on Friendly Persuasion.
- Complete the Wikiversity Course on Evaluating Evidence.
- Complete the Wikiversity Course on Thinking Scientifically.
- Check facts using reliable sources.

It will be helpful to study example Theories of Knowledge to prepare yourself to write your own.
Survey this gallery of example Theories of Knowledge to understand better how one might be designed and written down. If any of these appeals to you, feel free to adopt it. If you disagree with these, or believe you can improve on these, then please write your own, using the instructions given in the next section.
Developing your own Theory of Knowledge
I hope the background provided in this course so far motives you to create your own theory of knowledge. In this section you will examine how you decide what to believe and write it down; this is your own theory of knowledge. Let’s get started.
- Study the materials suggested in this annotated version of the template to expand your thinking about how best to decide what to believe.
- Answer the questions in this template to focus your thinking on this topic. Use the template to get started, and begin knowing how you know.
- Using your answers to the questions in the template as source material, write your theory of knowledge as a series of steps or decision rules.
Testing your Theory of Knowledge
Your theory of knowledge will get refined as you use it to decide what to believe. The next assignment provides some questions to use to gain experience using and testing your Theory of Knowledge.
- Choose 5 questions from this list of general knowledge questions to research.
- Research answers to these questions using any sources deemed reliable by your own Theory of Knowledge.
- Refine your written Theory of Knowledge if you find it difficult to use, or if it gives surprising, conflicting, or unreliable results.
- Continue to align your beliefs with reality.
Applying your Theory of Knowledge
Use your theory of Knowledge every day to decide what to believe, and to refine and purify your knowledge stream.
- Pay attention to new information as it reaches you. This information may arrive from a news report, social media, books, conversation, podcast, text message, email, phone conversation, gossip, rumors, or other sources.
- Notice if you are inclined to believe this new information or if you are inclined to doubt it.
- Analyze why and how you decided to believe or disbelieve this new information.
- Scrutinize this new information by applying each of the steps of your newly-developed Theory of knowledge.
- Notice if applying your newly-developed Theory of knowledge changes your mind about the new information.
- Scan your own beliefs to identify some that may not be well justified.
- Subject beliefs you have held for some time to your newly-developed Theory of knowledge.
- Note if: 1) They are confirmed by your theory of knowledge, 2) your new theory of knowledge causes you to modify, doubt, or change your beliefs, or 3) you refine your theory of knowledge to better reflect your concept of truth.
