Sharpen Your Thinking with These 10 Powerful Cognitive Razors
Improve Your Decision-Making with These 10 Cognitive Razors
The average adult makes about 35,000 conscious decisions each day.
Given this sheer volume of choice, how do we ensure we’re making the right decisions, day in and day out, without becoming exhausted?
Using insights from investor and thought leader Sahil Bloom, this graphic shares 10 cognitive razors, or rules of thumb, that can help you simplify your decision-making.
We’ve organized Bloom’s favorite cognitive razors into three overarching categories, which we dive into in further detail below.
Location, Location, Location
The first theme is location, and the importance of being at the right place at the right time.
The Luck Razor falls into this category because it highlights the importance of putting yourself out there. According to the Luck Razor, when choosing between two paths, pick the one with the largest “luck surface area,” or the path that offers you the most opportunity to get lucky.
This is because when you’re networking, meeting people, and building new relationships, you’re much more likely to stumble upon an opportunity than if you were sitting on your couch, not taking action.
The Rooms Razor follows a similar theme because it emphasizes the importance of your surroundings. It stresses that, if you have a choice between two rooms to walk into, choose the one where you’re most likely to be the dumbest person in the room.
While it’s a bit of an uncomfortable situation, it provides a greater opportunity for growth, as long as you check your ego at the door and listen to what others have to say.
Lastly, the Arena Razor reminds us that when we want something, we need to take the necessary steps to make it happen.
For instance, if you want to become a social media influencer, you need to start creating content and posting it online. It’s not easy to put yourself out there and take action, but if you want to play the game, you need to be in the arena.
The Power of Positive Thinking
The next theme is the power of mindset and positive thinking. This relates to how you view your life, the people you choose to surround yourself with, and how you interpret the actions and opinions of others.
According to the Gratitude Razor, when in doubt, don’t hesitate to show your gratitude to people who have supported you, or given you advice or opportunities.
Research studies have shown that expressing gratitude and giving thanks can be correlated with greater happiness, improved health, and stronger more meaningful relationships. So make sure to say thank you regularly, and tell your loved ones how much you appreciate their support.
It’s not just your mindset that’s important, though. The Optimist Razor recommends surrounding yourself with optimists, rather than pessimists. Pessimists may point out everything that could go wrong in a scenario, which might discourage you to break out of your comfort zone.
Optimism, on the other hand, will emphasize everything that could go right—and may even help you problem solve if you encounter problems along the way.
Keep Decision-Making Simple, Silly
The last one is quite simple, really: don’t overcomplicate things.
Occam’s Razor, which is named after the 14th-century scholar Franciscan friar William of Ockham, is generally interpreted as the following: when faced with a decision between two competing theories that generate the same outcome, the simplest theory is often the best one.
As Bloom says in this blog post, “simple assumptions [over] complex assumptions. If you have to believe a complex, intertwined series of assumptions in order to reach one specific conclusion, always ask whether there is a simple alternative assumption that fits.”
The ability to make things simple is also a good indicator of how deeply you understand something. According to the Feynman Razor, if you can’t explain a concept simply, then you don’t really understand it. So, if someone uses a ton of jargon or complexity to explain something, they could be masking a lack of deeper knowledge on the topic.

Mapped: Population Growth by Region (1900-2050F)
In this visualization, we map the populations of major regions at three different points in time: 1900, 2000, and 2050 (forecasted).

In fewer than 50 years, the world population has doubled in size, jumping from 4 to 8 billion.
In this visualization, we map the populations of major regions at three different points in time: 1900, 2000, and 2050 (forecasted). Figures come from Our World in Data as of March 2023, using the United Nations medium-fertility scenario.
Population by Continent (1900-2050F)
Asia was the biggest driver of global population growth over the course of the 20th century. In fact, the continent’s population grew by 2.8 billion people from 1900 to 2000, compared to just 680 million from the second on our list, Africa.
Region | 1900 | 2000 | 2050F |
---|---|---|---|
Asia | 931,021,418 | 3,735,089,775 | 5,291,555,919 |
Africa | 138,752,199 | 818,952,374 | 2,485,135,689 |
Europe | 406,610,221 | 727,917,165 | 704,398,730 |
North America | 104,231,973 | 486,364,446 | 679,488,449 |
South America | 41,330,704 | 349,634,344 | 491,078,697 |
Oceania | 5,936,615 | 31,223,133 | 57,834,753 |
World 🌐 | 1,627,883,130 | 6,149,181,237 | 9,709,492,237 |
China was the main source of Asia’s population expansion, though its population growth has slowed in recent years. That’s why in 2023, India surpassed China to become the world’s most populous country.
Southeast Asian countries like the Philippines and Indonesia have also been big drivers of Asia’s population boom to this point.
The Future: Africa to Hit 2.5 Billion by 2050
Under the UN’s medium-fertility scenario (all countries converge at a birthrate of 1.85 children per woman by 2050), Africa will solidify its place as the world’s second most populous region.
Three countries—Nigeria, Ethiopia, and Egypt—will account for roughly 30% of that 2.5 billion population figure.
Meanwhile, both North America and South America are expected to see a slowdown in population growth, while Europe is the only region that will shrink by 2050.
A century ago, Europe’s population was close to 30% of the world total. Today, that figure stands at less than 10%.
