Critical Thinking Starts with Careful Questioning

Welcome to Asking Better Questions and Seeking Perspectives! Critical thinking starts with the types of questions you ask. Drawing inspiration from John Coleman from the HBR Guide to Critical Thinking, this lesson will show you how to sharpen your inquiry skills, challenge your own assumptions, and seek new perspectives that expand your thinking.

You'll learn to approach complex problems with curiosity and humility, listen actively to what’s being said (and not said), and craft questions that spark genuine insight. By the end of this course, you’ll be ready to engage uncertainty with better questions and seeking different perspectives—leading not only to smarter decisions, but also to stronger leadership and deeper collaboration.

It’s natural to form an early theory or answer when you face a problem. This approach, sometimes called hypothesis-driven thinking, keeps you moving and helps clarify your options. But there’s a catch: when you become attached to your initial answer, your mind automatically looks for evidence that supports it, while ignoring anything that doesn’t fit. That’s how confirmation bias quietly sets in.

Think of it like wearing tinted glasses. Imagine you put on a pair of blue-tinted lenses and walk around believing everything you see must have a blue hue. You might miss the true colors of the world—even the brightest reds or yellows—because your brain is constantly filtering information through that blue tint. In the same way, when you get fixated on your first answer to a problem, you start filtering every new piece of information to fit that early theory, even if it means overlooking important facts or alternative solutions.

Instead, treat your first idea as a starting point, not a verdict. Ask questions that challenge your assumptions instead of just confirming them. For example, compare these two responses:

• “Don’t you think this approach makes the most sense?” (designed for agreement)
• “What would make this approach fail?” (exploring risks and blind spots)

The second question helps you break out of your own echo chamber and invites others to test your thinking.

This tendency also affects teams. When everyone starts to see things through the same “tinted glasses,” it leads to groupthink, where a group unconsciously favors harmony and consensus over exploring different perspectives. Deliberately consider the counterintuitive or unexpected possibility, and invite others to question the obvious. Involving diverse voices and asking, “What are we missing?” or “If we’re wrong, what might be the reason?” helps break the pattern and encourages richer, more creative solutions.

It’s uncomfortable to reconsider what you believe, but that discomfort is exactly where your best insights happen. Practice seeking out evidence that could prove you wrong, and welcome those moments when a better question leads you somewhere unexpected. That’s the heart of real critical thinking.
