What critical thinking means in practice
Critical thinking is the ability to engage actively with ideas rather than accepting them at face value. It involves analysing arguments, questioning assumptions, weighing evidence, and reaching conclusions that are reasoned and defensible.
At university, critical thinking shapes how you read, write, and contribute to discussion. In the workplace, it shapes how you approach decisions, assess information, and respond to ambiguity.
Across different roles and sectors, critical thinking underpins sound judgement and responsible action.
Questioning information and assumptions
In academic work, critical thinking involves asking what an author is arguing, what evidence they use, and what assumptions underpin their position. The same habits apply in professional settings.In the workplace, information is often incomplete, time‑limited, or shaped by organisational priorities. Critical thinking helps you question what is being presented, consider what might be missing, and avoid taking claims at face value.
Workplace examples:
- Reviewing a report and questioning the assumptions behind the data or projections.
- Asking clarifying questions when a proposed solution is presented as “obvious” or “best practice”.
- Noticing when decisions are based on precedent rather than evidence.
Reflective prompts:
- When have you questioned an idea or recommendation rather than accepting it immediately?
- What helped you recognise that further scrutiny was needed?
Evaluating evidence and sources
Critical thinking involves judging the quality and relevance of evidence. This includes recognising bias, limitations, and uncertainty, and understanding how context shapes interpretation.
In professional contexts, evidence may include data, client feedback, expert opinion, or organisational knowledge. Critical thinkers assess how reliable this information is and how confidently conclusions can be drawn.
This aspect of critical thinking is closely linked to research and analysis skills developed through academic study.
Workplace examples:
- Comparing different sources of information before making a recommendation.
- Recognising when data is outdated, incomplete, or selectively presented.
- Balancing quantitative evidence with contextual or qualitative insight.
Reflective prompts:
- How do you decide whether information is trustworthy or sufficient?
- When have you had to make a judgement with imperfect evidence?
Forming and explaining judgements
Critical thinking is not only about analysis. It also involves forming a clear position and being able to explain how you reached it.
At work, this might involve making recommendations, prioritising options, or explaining trade‑offs. Strong critical thinkers can articulate their reasoning, acknowledge uncertainty, and respond constructively to challenge.
This links closely to communication skills and ethical awareness, particularly when decisions affect others.
Workplace examples:
- Explaining why you support one option over another in a team discussion.
- Responding calmly when your reasoning is questioned.
- Acknowledging risks or limitations rather than overstating confidence.
Reflective prompts:
- How comfortable are you explaining your reasoning to others?
- How do you respond when someone disagrees with your conclusion?
Critical thinking in collaboration and decision making
Critical thinking is often developed and applied through interaction with others. In meetings, group work, and collaborative projects, it supports productive challenge and shared understanding.
Listening carefully, building on others’ ideas, and engaging with disagreement are all expressions of critical thinking in practice.
This connects critical thinking to teamwork and collaboration, as well as leadership and initiative.
Workplace examples:
- Contributing thoughtful questions in meetings rather than remaining silent.
- Challenging ideas respectfully while remaining open to being challenged yourself.
- Helping a group move beyond surface agreement to a better‑reasoned outcome.
Developing critical thinking over time
Critical thinking develops through practice, feedback, and reflection. Academic study at LSE provides structured opportunities to build this skill, but development continues through experience.
Progress often involves becoming more comfortable with complexity and uncertainty. Rather than seeking certainty, critical thinkers learn to make informed judgements while remaining open to revision.
Reflecting on how you approach decisions, arguments, and evidence can help you recognise and articulate your development over time.
Reflective prompts:
- How has your approach to judgement and decision making changed since starting university?
- Which experiences have most stretched your thinking?
