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.

Explainer: The Basics of DNA and Genetic Systems
While there is great diversity among living things, we all have one thing in common—we all rely on a genetic system made up of DNA and/or RNA.
But how do genetic systems work, and to what extent do they vary across species?
This graphic by Anne-Lise Paris explores the basics of DNA and genetic systems, including how they’re structured, and how they differ across species.
Composition of Genetic Systems: DNA and RNA
A genetic system is essentially a set of instructions that dictate our genetic makeup—what we look like and how we interact with our environment.
This set of instructions is stored in nucleic acids, the two main types being deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
DNA is made up of four molecules, known as nucleotides: Adenine (A), Thymine (T), Cytosine ( C), and Guanine (G). These nucleotides are grouped in sets of two, which are called base pairs.
Size of Genomes Across Different Organisms
Human DNA is made up of approximately 3.2 billion base pairs that are tightly wound up and stored in our cells. If you were to unwind and measure the DNA stored in a single human cell, it would be about 2 meters (6.5 feet) long!
This lengthy DNA is stored in pairs of chromosomes. A full collection of chromosomes, or an entire set of genetic information, is referred to as a genome.
Genomes vary in size, depending on the organism. Here is a look at 24 different species and the size of their genomes, from animals and plants to bacteria and viruses:
|Organism||Kingdom||Size of genomes (number of base pairs)|
|Hepatitis D virus||Virus||1,700|
The Marbled Lungfish has the largest known animal genome. Its genome is made up of 130 billion base pairs, which is about 126.8 billion more than the average human genome.
Comparatively, small viruses and bacteria have fewer base pairs. The Hepatitis D virus has only 1,700 base pairs, while E. coli bacteria has 4.6 million. Interestingly, research has not found a link between the size of a species’ genome and the organism’s size or complexity.
In fact, there are still a ton of unanswered questions in the field of genome research. Why do some species have small genomes? Why do some have a ton of redundant DNA? These are still questions being investigated by scientists today.
Mapped: Which Countries Still Have a Monarchy?
Beyond the 15 nations under the British monarchy, 28 other countries still have a ruling monarch. Here’s a look at the world’s monarchies.
Mapped: Which Countries Still Have a Monarchy?
In the wake of Queen Elizabeth II’s death, the question of monarchy is brought sharply into focus.
However, a surprising number of countries have ruling monarchs, and in this visual we break down the kinds of royal leadership across the 43 countries that still have them.
Types of Monarchies
A monarch in the simplest sense is a country’s king, queen, emir, or sultan, and so on. But before diving in, it’s important to break down the distinctions between the types of monarchies that exist today. Generally, there are four kinds:
① Constitutional Monarchy
The monarch divides power with a constitutionally founded government. In this situation, the monarch, while having ceremonial duties and certain responsibilities, does not have any political power. For example, the UK’s monarch must sign all laws to make them official, but has no power to change or reject new laws.
Here are some examples of countries with constitutional monarchies:
🇬🇧 United Kingdom
② Absolute Monarchy
The monarch has full and absolute political power. They can amend, reject, or create laws, represent the country’s interests abroad, appoint political leaders, and so on.
Here are some examples of countries with absolute monarchies:
🇸🇦 Saudi Arabia
🇻🇦 Vatican City
③ Federal Monarchy
The monarch serves an overall figurehead of the federation of states which have their own governments, or even monarchies, ruling them.
Here are some examples of countries with federal monarchies:
Malaysia is a unique form of federal monarchy. Every five years, each state’s royal leaders choose amongst themselves who will be the monarch, or the Yang di-Pertuan Agong, of Malaysia and the respective states. Furthermore, the monarchy is also constitutional, allowing a democratically elected body to govern.
④ Mixed Monarchy
This is a situation wherein an absolute monarch may divide powers in distinct ways specific to the country.
Here are some examples of countries with mixed monarchies:
Interestingly, Liechtenstein is the only European monarchy that still practises strict agnatic primogeniture. Under agnatic primogeniture, the degree of kinship is determined by tracing descent from the nearest common ancestor through male ancestors.
Kings, Queens, Emperors, and Sultans Around the Globe
Now let’s break down the different monarchies country by country:
|Country||Type of Monarchy||Title of Head of State||Monarch||Title of Head of Government|
|🇦🇩 Andorra||Constitutional||Co-Princes||Joan-Enric Vives, Emmanuel Macron||Prime Minister|
|🇦🇬 Antigua and Barbuda||Constitutional||King||Charles III||Prime Minister|

|🇸🇦 Saudi Arabia||Absolute||King||Salman||Prime Minister|
|🇸🇧 Solomon Islands||Constitutional||King||Charles III||Prime Minister|
|🇪🇸 Spain||Constitutional||King||Felipe VI||President of the Government|
|🇸🇪 Sweden||Constitutional||King||Carl XVI Gustaf||Prime Minister|
|🇹🇭 Thailand||Constitutional||King||Rama X||Prime Minister|
|🇧🇸 The Bahamas||Constitutional||King||Charles III||Prime Minister|
|🇹🇴 Tonga||Constitutional||King||Tupou VI||Prime Minister|
|🇹🇻 Tuvalu||Constitutional||King||Charles III||Prime Minister|
|🇦🇪 UAE||Federal||President||Mohamed bin Zayed Al Nahyan||Prime Minister|
|🇬🇧 UK||Constitutional||King||Charles III||Prime Minister|
|🇻🇦 Vatican City||Absolute||Pope||Francis||President of the Pontifical Commission|
Constitutional monarchies are undoubtedly the most popular form of royal leadership in the modern era, making up close to 70% of all monarchies. This situation allows for democratically elected governments to rule the country, while the monarch performs ceremonial duties.
Most monarchs are hereditary, inheriting their position by luck of their birth, but interestingly, French president, Emmanuel Macron, technically serves as a Co-Prince of Andorra.
Another unique case is the Vatican’s Pope Francis, who has absolute power in the small independent city—he gained his role thanks to an election process known as a papal conclave.
The Role of Monarchies
One of the most notable and famous ruling monarchies is the United Kingdom’s House of Windsor—also known as Queen Elizabeth II’s family. King Charles III has now ascended to the country’s throne, making him head of state in 15 nations total, including Canada, Australia, and New Zealand.
Many see the benefit in having a stable and consistent form of tradition and decorum at the country’s head of state.
“The Crown is an integral part of the institution of Parliament. The Queen [now King] plays a constitutional role in opening and dissolving Parliament and approving Bills before they become law.” – British Parliament
Japan’s royal family has been a prime example of stability, having reigned in the country for more than 2,600 years under the same hereditary line.
Critiques and the Future of Monarchy
Some claim, however, that there is no function of monarchy in the modern day, and complaints of monarchies’ immense wealth and power are rampant.
For example, according to the Dutch government, King Willem-Alexander’s budget for 2022, funded by the state and thus, taxpayers, comes out to more than €48 million.
Beyond tax dollars, with absolute monarchies there is typically a lack of political freedoms and certain rights. Saudi Arabia, for example, has no national elections. Rather its king, Salman bin Abdulaziz Al Saud, stays in power for life, appoints the cabinet himself, and passes laws by royal decree.
The death of Queen Elizabeth, though, may bring about change though for many of the world’s royally-governed. Since Barbados’ removal of her as head of state in 2021, six other Caribbean nations have expressed the desire to do the same, namely:
🇧🇸 The Bahamas
🇦🇬 Antigua and Barbuda
🇰🇳 St. Kitts and Nevis
The future of monarchy in the 21st century is certainly not a guarantee.
