Developing critical thinking skills for executive-level careers

Executive overview

Critical thinking is not a destination but a disciplined process of reasoning using the brain's rational, executive function. Most professionals plateau because their conceptual frameworks — built from memorisation and criticism — stop updating. Three concepts unlock genuine development: learning from original thinkers, actively refreshing mental frameworks, and deepening self-awareness.

The fastest way to improve critical thinking is to stop consuming what's popular and start learning from original thinkers whose insights have stood the test of time.

Two characteristics of critical thinking

• A disciplined process — applied to any situation, conversation, or collaboration
• A way of reasoning — drawing on the brain's rational executive function, not emotional response
• Activities involved: analysing, conceptualising, and synthesising new information

Concept 1: Wisdom of the ages

• Prioritise sources from original thinkers over popular books and trending content
• Popular content tends to be general, fluffy, and recycled — wisdom is unborrowed and time-tested
• Think of knowledge as a tree: breadth in branches, but strength comes from the roots
• Deepen knowledge in your core field while building related breadth that gives it more meaning
• Seek individuals who have studied and synthesised wisdom from original sources

Concept 2: Conceptual frameworks

• Your brain makes sense of the world by building conceptual frameworks — frameworks for politics, relationships, your industry, every subject you've studied
• These frameworks represent your best thinking to date; they got you where you are now
• Frameworks may or may not be grounded in truth — they are shaped by personal observation and bias
• Most people read to memorise or to criticise; both habits lock in existing frameworks
• Reading to memorise limits wisdom gained; reading to criticise produces confirmation bias — discarding the very gaps you don't know you have
• Read instead to formulate new perspectives and actively update frameworks
• Keeping frameworks static caps your career at current levels; updating them opens new trajectories

Concept 3: Reflective awareness

• Reflective awareness means moving closer to your authentic self — knowing your characteristics, skills, traits, and intrinsic value without needing to prove them
• In the presence of senior leaders, most professionals feel intimidated or like an impostor
• Imposter syndrome stems from comparing your perceived gaps with others' visible achievements
• Practising reflective awareness — a conscious, deliberate brain activity — closes that gap
• Influence operates through only two levers: the actions you take and the perspectives you hold
