March 24th, 2008Know Why You Believe What You Believe
“I don’t know.” Perhaps you thought you understood a concept then when pushed to summarize the concept in a clear, concise statement, you found yourself uttering the feeble words “I don’t know.” Or maybe you asked your son to explain what he just read, and he weakly stammered “I don’t know.” If you can’t explain why you know something, then you don’t really know it!
The English word “critical” derives from the Greek word “kritikos” which means to question, to make sense of, or to analyze. Critical thinkers know why they believe what they believe because they have asked lots of questions, analyzed lots of data, and have made sense of the evidence. According to Merriam Webster, a belief is “a conviction of the truth of some statement or the reality of some being or phenomenon especially when based upon examination of evidence.” In evaluating beliefs, we need to consider four different kinds of evidence:
- Expert Authorities
- Written References
- Hard Facts
- Personal Experience
Expert Authorities
An authority is one who is an expert in a field and has usually devoted the majority of his working career to gaining a deep understanding of his area of expertise. Biblical scholars specialize in interpreting particular books of the Bible. Supreme Court justices specialize in Federal Constitutional Law. Anthropologists specialize in indigenous cultures. Who are the authorities for your core beliefs? Are they particularly knowledgeable in the area of the belief? Are they reliable? Have they ever given inaccurate information? Do other authorities disagree with their positions?
Written References
Original source documents like books, newspapers, online publications are written by authors who could be authorities or work for authorities. What texts do you rely upon to support your beliefs? Is the content of these texts based upon factual evidence? What are the credentials of the authors? How much personal experience does the author have with the topic? Does the author have a relationship with someone who is an authority on the topic? Are there other authors who disagree with the position that your texts endorse? Is there evidence to support the opinion of these texts?
Hard Facts
Facts are pieces of information presented as having objective reality; that is, facts can be objectively quantified or substantiated and are not subject to the interpretations of the user. When considering the facts behind your beliefs, inquire of the source of the facts. Were experiments performed to statistically quantify the facts? Was evidence obtained to substantiate the conclusions? Can this evidence be interpreted differently? Does the factual evidence support the conclusion?
Personal Experience
Many times our beliefs are based upon personal experiences. In evaluating these experiences, ask yourself the following questions. What were the circumstances of the experience? Were distortions or mistakes in perception possible? Have other people had similar or conflicting experiences? Are there other explanations for the experience?
You don’t have to examine each of these four types of evidence for every belief or position that you consider, but critical thinking skills will be improved if you practice asking these questions regularly. Think of a core belief that you hold about life then go through this exercise step by step. Some possible beliefs that you could examine are what you believe about marriage, parenting, or homeschooling. Here are the steps:
1. Describe the belief.
2. Explain the reasons why you feel so strongly about the belief.
3. Identify evidence for your position.
4. Describe an opposing point of view.
5. Identify evidence for the opposing viewpoint.
6. Evaluate the evidence for both pros and cons using the four categories above:
a. Who are the authorities?
b. What are the written references?
c. What are the facts?
d. What are your personal experiences?
Was that difficult to do? Now you’re ready to try this exercise with your child. Select an easy belief to start with then move on to more difficult beliefs. For instance, in my household, Handel’s Homemade Ice Cream is favored above all other brands, so I might guide the kids through the following analysis:
1. Handels Ice Cream is better than Ritters Custard.
2. Flavor, variety, texture, and price all support our position.
3. We know this from personal experience and newspaper articles showing consumer preferences.
4. Ritters Custard is better than Handels.
5. Some people prefer the lighter, creamier texture of custard as evidenced by all the cars parked in front of the building.
6. Finally, authorities, references, facts, and personal experiences would be considered for both Handels and Ritters.
You can use these tools to evaluate all kinds of beliefs from moral positions (like “I believe lying is wrong”) to scientific theories (like “I do not believe global warming is a threat to the earth”) to difficult worldview issues (like “I believe in the Trinity”). Start with the easier concepts from their math lessons (like “I believe nine times eight is seventy-two” or “I believe a right triangle has one 90 degree angle”) or from their history reading (like “I do not believe the American Civil War was caused by slavery” or “I believe that Benedict Arnold was a traitor”).
You might want to set aside a few minutes every morning to practice this exercise just like you would practice an impromptu speech. Give the kids a topic (abstract ideas like love and power or concrete ideas like evolution and property ownership), and set the timer for 10 minutes. Give them a notecard and have them complete the 6 steps above. When the timer goes off, have them narrate their thoughts from the notecard. I promise you that this exercise will really stimulate their thinking; it really reveals how much they do or do not know about their belief! Train your kids in how to evaluate their beliefs so that they can confidently give a precise, thoughtful answer next time when you ask them why they believe what they believe.
