Terry Rosen recounts how his high school mentor taught critical thinking by asking the class to heat water to 115°C. This impossible task forced students to rely on observation and scientific principles over blindly following instructions, instilling a foundational mindset for a career in science.

A mentor isn't someone who provides step-by-step instructions. The most powerful learning comes from finding someone you admire and closely observing their every move, how they speak, and how they behave in the face of obstacles, rather than seeking direct guidance.

Both the host and guest argue that the education system prioritizes memorization and regurgitation over critical thinking. True learning and problem-solving skills are often only developed after formal schooling, in real-world situations that demand independent thought rather than repeated answers.

An outdated leadership model pressures leaders to have all the answers. The superior, long-term approach is to focus on the individual, not the problem, by asking questions that guide them to their own solutions, thereby building their confidence and critical thinking skills.

Using the Sewol Ferry disaster, where students who obeyed instructions to stay put perished, former CIA officers argue for teaching kids that authority figures can be wrong. In emergencies, critical thinking and trusting one's own gut must supersede the ingrained habit of following orders, as it can be the difference between life and death.

The strength of scientific progress comes from 'individual humility'—the constant process of questioning assumptions and actively searching for errors. This embrace of being wrong, or doubting one's own work, is not a weakness but a superpower that leads to breakthroughs.

Instead of standard assignments, a teacher challenged a failing Elon Lee to find and fix errors in a new physics textbook. This reframing of education as a real-world research project ignited his passion, proving that unconventional, problem-solving-based tasks can engage students who struggle with traditional learning.

Top performers are frequently unable to teach their skills effectively because doing and teaching are separate abilities. Their verbal explanations may be inaccurate post-rationalizations. To truly learn from the best, ignore their narratives and instead meticulously observe and replicate their specific, observable behaviors.

Instead of teaching decision-making in isolation, education should integrate skills like counterfactual thinking directly into core subjects. Analyzing literature by asking, "What if Macbeth had chosen a different option?" makes the material more engaging and teaches critical thinking simultaneously.

Reflecting on his PhD, Terry Rosen emphasizes that experiments that fail are often the most telling. Instead of discarding negative results, scientists should analyze them deeply. Understanding *why* something didn't work provides critical insights that are essential for iteration and eventual success.

An oncology leader measures his contribution not by personal discoveries, but by his ability to coach and mentor the next generation. He believes the greatest legacy is enabling others to become even more brilliant and successful, effectively passing the baton to smarter people.
