Module 2: Identifying Assumptions and Biases

Overview:

Critical thinking requires awareness of hidden assumptions and cognitive biases that can distort reasoning. This module teaches learners to recognize these assumptions and biases in arguments, discussions, and daily situations. Understanding them helps make more objective and reasoned decisions.

Learning Objectives:

By the end of this module, learners will be able to:

1. Define assumptions and biases.
2. Identify common cognitive biases in statements and arguments.
3. Recognize implicit assumptions in claims or decisions.
4. Reflect on personal biases and how they affect thinking.

1. What are Assumptions?

1. Assumptions are ideas or beliefs taken for granted without proof.
2. They are often unstated and influence how we interpret information.

Example:

1. Statement: “If you study hard, you will pass exams.”
2. Assumption: Studying hard is the only factor affecting exam success.

2. What are Biases?

1. Biases are systematic tendencies to think in certain ways, often leading to errors in judgment.
2. They can be conscious or unconscious and affect decision-making.

Common Biases:

1. Confirmation Bias: Seeking information that supports existing beliefs.
2. Stereotyping: Making assumptions based on group membership.
3. Anchoring Bias: Relying too heavily on the first piece of information.
4. Availability Heuristic: Judging probability based on easily recalled examples.

3. Identifying Assumptions and Biases

Steps to Identify:

1. Ask: “What is being taken for granted?”
2. Look for evidence supporting the claim.
3. Consider alternative explanations or viewpoints.
4. Reflect on your own thinking: “Am I favoring one perspective without reason?”

Example:

1. Claim: “Teenagers spend too much time on social media; they are lazy.”
2. Assumptions: All teenagers use social media excessively; time on social media directly causes laziness.
3. Possible Bias: Stereotyping teenagers.

4. Personal Reflection on Biases

1. Everyone has biases, and being aware of them is the first step to critical thinking.
2. Reflect on your own decisions and beliefs. Are they influenced by emotion, habit, or unexamined assumptions?

Exercises

Exercise 1: Spot the Assumption

Identify the assumption in each statement:

1. “If someone is late, they must be irresponsible.”
2. “Reading novels improves intelligence.”
3. “Online learning is less effective than classroom learning.”

Exercise 2: Identify the Bias

Determine which bias is shown in each example:

1. “I don’t trust news from that website because it often disagrees with my opinion.”
2. “All people from that town are lazy.”
3. “I bought the first phone I saw, so it must be the best.”

Answer Key:

1. Confirmation Bias
2. Stereotyping
3. Anchoring Bias

Exercise 3: Personal Reflection

Think about a decision you recently made:

1. What assumptions did you make?
2. Did any biases influence your choice?
3. How could recognizing these assumptions or biases have improved your decision?
