B2/C1 Grammar: General Truths, Conditionals and Cautious Explanation

This video explains how our brains usually work, so the grammar focus is on zero and second conditionals, cause-and-effect language and cautious generalisations.

Example: If we had to consciously think through every decision, we would be overwhelmed.

Grammar Section 1: Zero Conditional for General Truths

1. Complete: “When heuristics cause poor choices, we ___ them cognitive biases.”

called call would called

2. Which sentence expresses a general truth?

If people feel attacked, they often become defensive. If people felt attacked, they often becomes defensive. If people attacked, defensive.

Grammar Section 2: Hypothetical Conditionals

1. Complete: “If we had to think through every decision, we ___ overwhelmed.”

are will be would be

2. Which sentence is correct?

If we were more self-aware, we might handle tough conversations better. If we are more self-aware, we might handled better. If self-aware, conversations better.

Grammar Section 3: Cautious Generalisations

1. Which sentence is appropriately cautious?

Everyone always makes biased decisions. Cognitive biases can affect our reasoning. Biases never matter.

2. Complete: “This may help explain why political discussions ___ uncomfortable.”

becomes becoming can become

Thought-Provoking Questions

Discuss these questions in pairs or small groups. Give reasons, examples and possible consequences.

1. Are heuristics more helpful or more dangerous in everyday life?

2. When have you jumped to a conclusion too quickly?

3. Why do challenges to our beliefs sometimes feel personal?

4. Can people become less biased, or only more aware of their biases?

5. How can schools teach students to recognise cognitive bias?

6. Is it always better to slow down before making a decision?

7. How can understanding bias improve political or social discussions?

Challenge: Choose one question and prepare a one-minute answer using cautious language such as: It could be argued that..., One possible concern is..., This becomes more complicated because...

Role Play

Explaining bias	Disagreeing politely	Slowing the conversation down
One possible bias here is... We may be jumping to conclusions. Our brains often rely on shortcuts.	I understand why it feels that way, but... Could we look at the evidence? There may be another explanation.	Let’s slow down for a moment. What information are we missing? Before deciding, we should consider...

Context

Situation: Two colleagues are discussing a new candidate for a job. One colleague makes assumptions based on a stereotype. The other tries to identify the bias and make the discussion more evidence-based.

Student A

You are making a quick judgement about the candidate. Explain your reasoning, but be open to being challenged.

Student B

You notice a possible cognitive bias. Politely challenge the assumption and ask for evidence.

Role play task: Discuss the candidate for five minutes. By the end, agree on three pieces of evidence you need before making a fair decision.
