We all want to see the world clearly. The trouble is, we're never taught how.
Join Shane Parrish - 'the former spy who helps Wall Street mavens think smarter' (New York Times) - for a masterclass in the art of clear thinking. Drawing on examples ranging from the evolutionary origins of our 'emotion default' to the secret history of the Challenger disaster, Parrish offers powerful mental models to make sense of any situation. And he reveals a simple, actionable method for smarter decision-making, starting today.
Along the way, he shows that the secret to mental clarity lies not in how we approach the most high-stakes moments - but in our tiniest, most everyday decisions.
It's a simple idea with startling implications: if you clear your head today, you change your life tomorrow.

- Reviewed in the United Kingdom on 28 December 2024I liked this book as it didn't give you a formula that you had to follow, but gave you more of a number of skills and principles that you can apply to help with making good decisions.
- Reviewed in the United Kingdom on 23 November 2023As a long-time subscriber to the author's blog, I approached "Clear Thinking" with a mix of anticipation and curiosity. The book does not disappoint in delivering the insightful and thought-provoking content that fans of the blog have come to expect.
"Clear Thinking" is a well-crafted distillation of the author's key ideas and principles, presented in a format that's accessible to both new readers and those familiar with his work. However, for regular followers of his blog, the book may tread familiar territory. Much of the content echoes the themes and insights that are regularly explored in his online writings.
That said, the book's strength lies in its cohesive structure and the ease with which it guides the reader through complex concepts. It serves as a handy reference and a comprehensive collection of the author's ideas, all in one place.
For newcomers, "Clear Thinking" is an excellent introduction to the author's work, providing valuable insights and practical advice for navigating life's challenges with a more analytical and thoughtful approach. For blog subscribers, while the content might not be entirely new, the book offers a consolidated and well-organized view of the author's philosophy and teachings.
Overall, "Clear Thinking" earns a solid four stars for its clarity, coherence, and the valuable perspectives it offers, even if it might feel like a familiar journey for long-time followers of the author's blog.
- Reviewed in the United Kingdom on 7 October 2023It’s full of insight that you probably have already read, sometimes do and often hear but it’s pulled together in a simple and practical way that flows very well and makes you want to read it again.
- Reviewed in the United Kingdom on 20 December 2023Having read Shane's books on Mental Models (which I also highly recommend) I was really looking forward to this book.
This book explores the skill of Clear Thinking and Shane brings to life various ways with which you can first create a space to reason in your thoughts, feelings and actions and using that space to think clearly.
The book is great at creating an awareness of how we may think by default whether it's through biological instincts or other conditioning we have. It helps you understand your strengths and weaknesses and then leveraging those, creating a pause between thought and action and leveraging clear thinking to make great decisions.
There are some fascinating insights in behavioural science and Shane uses very interesting and engaging stories to bring to life concepts and some really useful principles in action.
This is information that's not easy to find in any other regular book so it's been very useful learning for me. Think of this book as firstly helping you understand what typically affects you and everyone else, it then helps you identify working with your strengths and weaknesses, it brings to light various examples of principles in action through powerful storytelling and it then provides you with a framework that you can use to better control your own thinking and decision making.
It is a book worth studying, it's great for reference, I keep it at my desk as I am exploring these concepts and certainly has opened up eyes to things I had not considered to improve my thinking.

- Reviewed in the United Kingdom on 6 December 2023I am an occasional reader of Shane's blog and listener of his podcast. His focus has always been on finding timeless wisdom from experts, and using it to make better decisions about life.
This book is along those lines. The main message is that we are biologically hardwired to fall back to certain default behaviours - which are not always in our long term interests - and so we need to be aware of these and do things to give us more space to think clearly.
These "defaults" are split into broad categories: the ego default (preserving ourselves), the emotion default (responding to emotions), the inertia default (resisting change) and the social default (following what others do).
The rest of the book is advice for how to make better decisions given this reality. Some of strategies include identifying "personal exemplars" to model behaviour from, changing environments to set a better default, having rules (don't say yes to a big decision without sleeping on it), making checklists etc. Others involve mindset or behavioural shifts like taking more responsibility for things, fixing mistakes properly etc.
It finishes off with a section that reminds us that not everything we think we want is worth wanting, and to think and make decisions with meaningful goals in mind.
Overall it was a fun read and reminds us of what is important not just in the long term, but what is important to do every day.
- Reviewed in the United Kingdom on 26 November 2024The book isnt bad and there is plenty of small text but not sure ifnits the writers style in putting down facts but im really strugfling to gwt into this. Bored of the waffle and lack of points, examples are far fetched, too long and dont resonate. Wouldnt recommend in a hurry.
- Reviewed in the United Kingdom on 13 July 2024Heard Shane Parrish being interviewed by Chris Evans and decided to get his book. Have been listening to his podcast, The Knowledge Project, and learning a lot from that too.
This book gives insights in how making small changes that enable you to make better decisions consistently. It’s those small day to day decisions that compound into larger positive outcomes over time.
Will be ordering his Mental Model books
- Reviewed in the United Kingdom on 27 May 2024As an over thinker, I felt this book understood that and explained why and how to change this. It will definitely take work and progress but thats what self development and self growth are.

5.0 out of 5 stars Take Charge of Your Decision Making
Shane Parrish founder of the popular blog site Farnam Street has authored a book about decision making called Clear Thinking. Parrish has spent much of his working life seeking to answers to questions like, “How can we get better at reasoning? Why do people make bad decisions? Why do some people consistently get better results than others who have the same information? How can I be right more often, and decrease the probability of a bad outcome when lives are on the line?” The quality of our decisions is a large contributor to the quality of our lives. And yet, we aren’t taught that decision making is a skill.
Parrish proposes that better decisions follow two steps. First, we must make time to think. We must resist the reflex to react. Then we must use the time created to think. Like much good advice, both are easier said than done.
Creating space for cognition is tough because our biology can get in the way. We think we’re thinking but are as likely to be simply reacting. We want to repulse at our impulse. Four defaults are detailed by Parrish which can disrupt our ability to think. The emotional default prioritizes feelings over facts. We react to our feelings and only pay attention to things that improve our feelings. Who is in charge? Are you moved by your waves of emotion or by your conscious cognition? A second default is our ego. We are sensitive to criticism and attacks against our self-worth. Where we sit in our social group is very important for us to protect. We want to be seen in a positive light. We will react defensively to attacks. Parrish writes, “Our desire to protect ourselves prevents us from moving forward.” We will work to rationalize our decision instead of evaluate information. Third, the social default is the drive we have to fit in with our peers. We don’t want to stick out. Being a contrarian isn’t comfortable. We want, if not the respect and admiration, at least the acceptance of our peers. Parrish quotes Walter Lippmann capturing the cost of the social default when he wrote, “Where all think alike, no one thinks very much.” The concern with the social default is conformity. Dissent is less likely. Critical thought is sidelined in favor of favorable group, social dynamics. Finally, the inertia default prizes the status quo. We crave comfort and change creates uncertainty which is uncomfortable. As a result of the inertia default, we’re more likely to leave things as they are and defer decisions to change.
Physical and mental stressors can increase the likelihood that we’ll lean on our defaults. If we’re tired, hungry, distracted, angry, stressed, rushed, or somewhere unfamiliar, our defaults are likely to kick in compromising our ability to see things clearly and make good decisions. Developing an awareness of defaults and their tendency to disrupt decision making is the starting point to getting out of our own way. Awareness of defaults helps us tune our antennae to allow us to insert our thinking self into the equation earlier to avoid dependence on defaults. Parrish writes, “Strength is the power to press pause on your defaults and exercise good judgment.”
A way we can work to give ourselves a chance is to set up environments for success to avoid some of our vulnerabilities like sleep, nutrition, distraction, etc. We can create a rule to adopt the HALT strategy. That is, avoid making decisions when Hungry, Angry, Lonely, or Tired. A separate rule to consider, for example, is never say yes to something without sitting with it overnight. Avoid being forced into a decision in the moment. Parrish proposes we seek safeguards to set up success. We can control our environments to rid ourselves of interruptions to reduce being pressured into decision making. Create checklists which are several rules piled into a routine which help us stay on track. They force us to slow down and engage mentally in a process allowing us to ask as Parrish writes, “What am I trying to accomplish? And what are the things I need to accomplish it?”
Associated with accelerating awareness of our defaults (weaknesses) and controlling our environment is assuming responsibility for your decision making. We need to not just accept but embrace the responsibility we have for our decisions. When we see the importance of our role in decision making coupled with the value of quality decision making to our lives, we’ll heighten our awareness of defaults and want to work harder to build time to think. Avoiding accountability for our decisions and complaining both weakens and devalues us. Complaining is an assault on agency. We can’t be victorious while being a victim. When we’re hopeless, we become helpless. Taking responsibility may be tough, but it’s empowering. No, you don’t and can’t control everything. However, your actions contribute to your direction. Focusing on what we can control and making the most of the decisions with which we’re faced are the best ways to make progress in life. Recognizing reality is about placing our feelings in the back seat and deciding based on facts. Parrish quotes James Clear offering, “Life gets easier when you don’t blame other people and focus on what you can control.”
We can think of our decisions as binary points where what we decide will either help us or hurt us. This binary becomes our decision driver. Parrish offers, “Each moment puts you in a better or worse position to handle the future.” He encourages us to ask, “Will this action make the future easier or harder?” It is in our moments of decision that our future is determined.
Once we’ve created time to make choices consciously, we now need to use this time to make better decisions. Parrish presents four stages for decision making: defining the problem, exploring solutions, evaluating options, and executing the best option.
Defining the problem must be done by the decider. Deciders define their problem in two steps. First, what is to be achieved. Second, what impediments lie in the way of where I/we want to go? Parrish suggests that how a problem is defined shapes how and what becomes seen. The definition determines the perspective. It’s also important when defining the decision that the root cause be rooted out as opposed to going after a surface level symptom. The definition of the problem should consider not just the immediate situation but the longer term as well. Engaging in an initial conversation focused solely on defining the problem ensures that solutions don’t creep into the conversation prematurely. Try to document your efforts to define the problem. The more you preserve your process, the more you will be able to review and learn from it after the solution has been selected and executed.
Solutions can be sought once the problem has been defined. The goal is to seek out several. Avoid being limited to one or two options. Seek a minimum of three potential solutions to evaluate.
Once solutions have been surfaced, they must then be evaluated. Each solution should be weighed based on their pros and cons. What is good about a potential solution and what limitations are there? No solution is perfect. What are the opportunity costs associated with a given solution? Remember, the best solution is the one that will, as Parrish writes, “make the future easier.” As part of this step, your goal is to determine evaluation criteria. How will each solution be weighed? Do you have a clear decision filter through which you’ll be sifting your solutions? Do you have a clear set of priorities? Ideally, a single priority as the goal for the solution to serve. Again, writing things down is an asset here as it makes your process concrete and allows the future outcome to be weighed against your decision-making process.
Parrish proposes a sticky note battle to prioritize choice criteria. List individual criteria on a single sticky note and stack one by one the others against it until you have your hierarchy of what’s important for your solution to serve. Once you’ve selected your solution, you reach the final stage of the decision-making process. It’s time to execute. Parrish offers the military idea of Commander’s Intent as an approach to adopt to assist execution in a team environment. To avoid the leader becoming the weak link in the execution chain, the leader gives the group the driving principle behind the goal a decision is intended to achieve. This is the intent that others will rely on to make their own determination of what to do. This passes the baton for execution from the leader to the front lines. It empowers those around you to act with confidence and in service of the ultimate objective keeping things moving.
An often-overlooked consideration in decision making is the cost of analysis itself. Too much time spent deliberating instead of doing has its own limitations. Parrish offers the ASAP and ALAP principles to help move things along when needed while allowing for time to discuss when the nature of the decision is more vital. The ASAP principle, Parrish writes applies, “If the cost to undo the decision is low, make it as soon as possible.” Whereas, the ALAP principle is, “If the cost to undo a decision is high, make it as late as possible.”
At the end of the day Parrish writes, “The quality of your decisions eventually determines how far you go and how fast you get there.” Getting better at making decisions should be a goal for all of us and Clear Thinking is both readable and actionable to help us in this regard. There’s much wisdom contained within that can be put to use right away for readers in their personal and professional lives.

5.0 out of 5 stars very systematic ,and non repetitive & well explained.
Could connect with about 80% the author mentioned. However there are some contradictions I had but that’s something most people will based on their own life experiences .
From a spiritual standpoint there are some fundamental differences I have felt, although it does include stoic philosophy in some aspects.
Overall worth a read . It also explains why you should read a book rather than just rely on summary’s
