Overwhelmed by choices, short on time, and second-guessing your calls?

Most advice says “think harder.” This book shows you how to think better with practical mental models you can use before the next meeting, purchase, or life decision. Mental Models for Critical Thinking is a field guide to clear judgment under uncertainty. In plain language and real examples, Albert Rutherford turns fuzzy concepts into usable playbooks so you can frame problems correctly, reduce bias, and choose with confidence.

Critical thinking isn’t a talent; it’s a system. By pairing each core skill (analysis, evaluation, inference, problem-solving, reflection, metacognition) with a matching mental model, you get a map you can trust when stakes are high and time is short.

If your decisions feel ad-hoc and inconsistent…The 5-Step Decision Playbook gives you a repeatable path from mess to choice. You’ll standardize how you think, compare options on the same footing, and create a paper trail you can review to improve the next call.

If assumptions keep steering you wrong…First Principles forces hidden beliefs into the open so you design from truth, not tradition. You’ll strip problems to essentials, rebuild smarter systems, and stop treating symptoms.

If you keep fixing the wrong thing…Inversion flips the question to “what would make this fail?” so blind spots surface fast. By stress-testing the negative path first, you avoid preventable errors and choose safeguards that actually matter.

If problems recur because root causes stay hidden… The Five Whys walks you past symptoms in five honest steps to the underlying cause. Solve the deepest driver once, and you won’t keep paying for the same mistake.

Upgrade the way you think so you can upgrade what you choose. Open to any page, steal a tool, and make your next decision the best one you’ve made all week.
