The level of a person’s raw intelligence, as measured by aptitude tests such as IQ scores, is generally stable for most people during the course of their adulthood.
While it’s true that there are things you can do to fine tune your natural capabilities, such as doing brain exercises, solving puzzles, and getting optimal sleepโthe amount of raw brainpower you have is difficult to increase in any meaningful or permanent way.
For those of us who constantly strive to be high-performers in our fields, this seems like bad news. If we can’t increase our processing power, then how can we solve life’s bigger problems as we move up the ladder?
The Key: Mental Models
The good news is that while raw cognitive abilities matter, it’s how you use and harness those abilities that really makes the difference.
The world’s most successful people, from Ray Dalio to Warren Buffett, are not necessarily leagues above the rest of us in raw intelligenceโinstead, they simply develop and learn to apply better mental models of how the world works, and they use these principles to filter their thoughts, decisions, strategies, and execution.
This infographic comes from best-selling author and entrepreneur Michael Simmons, who has collected over 650 mental models through his work. The infographic, in a similar style to one we previously published on cognitive biases, synthesizes these models down to the most useful and universal mental models that people should learn to master first.
Concepts such as the 80/20 rule (Pareto’s principle), compound interest, and network building are summarized in the visualization, and their major components are broken down further within the circle.
Mental Model Examples
Example #1: Pareto’s Principle (80/20 Rule for Prioritization)
In a recent Medium post by Simmons, he highlights a well-known mental model that is the perfect bread crumb to start with.
The 80/20 rule (Pareto’s principle) is named after Italian economist Vilfredo Pareto, who was likely the first person to note the 80/20 connection in an 1896 paper.
In short, it shows that 20% of inputs (work, time, effort) often leads to 80% of outputs (performance, sales, revenue, etc.), creating an extremely vivid mental framework for making prioritization decisions.
The 80/20 rule represents a power law distribution that has been empirically shown to exist throughout nature, and it also has huge implications on business.
If you focus your effort on these 20% of tasks first, and get the most out of them, you will be able to drive results much more efficiently than wasting time on the 80% “long-tail” shown below.
Example #2: Metcalfe’s Law (Network Building)
Metcalfe’s Law is one of network effects, stating that a network’s value is proportional to the square of the number of nodes in the network.
From a mental model perspective, this is a useful way to understand how certain types of technology-driven businesses derive value.
If you have a smart grid that is only connected to one power source, that’s alrightโbut one connected to many different energy sources and potential consumers is much more useful for everyone on the grid. Each additional node provides value for the rest of the connections.
This mental model can be applied outside of strict technology or business terms as well.
For example, if you build a personal network of connections, each additional relationship can provide more value to the other people in your network. It’s the same principle that Harvard or other prestigious universities operate on: the more value a student can get from the alumni network, the higher price they can charge for tuition.
It’s hard to compete with a fully formed network at scale, as they create massive economic moats for the owner. Modern social networks and messaging apps like Facebook, Instagram, LinkedIn, TikTok, WhatsApp, and Snapchat all operate with this in mind.
The Power of Mental Models
These are just two examples of how powerful mental models can be effective in making you think clearer and work smarter.
If you want to be a top performer, itโs worth looking into other mental models out there as well. They can help you better frame reality, so that you can harness your intelligence and effort in the most effective way possibleโand itโll allow you to deliver results along the way.

Politics
Charted: The Number of Democracies Globally
How many democracies does the world have? This visual shows the change since 1945 and the top nations becoming more (and less) democratic.

Charted: The Number of Democracies Globally
The end of World War II in 1945 was a turning point for democracies around the world.
Before this critical turning point in geopolitics, democracies made up only a small number of the world’s countries, both legally and in practice. However, over the course of the next six decades, the number of democratic nations would more than quadruple.
Interestingly, studies have found that this trend has recently reversed as of the 2010s, with democracies and non-democracies now in a deadlock.
In this visualization, Staffan Landin uses data from V-DEMโs Electoral Democratic Index (EDI) to highlight the changing face of global politics over the past two decades and the nations that contributed the most to this change.
The Methodology
V-DEM’s EDI attempts to measure democratic development in a comprehensive way, through the contributions of 3,700 experts from countries around the world.
Instead of relying on each nation’s legally recognized system of government, the EDI analyzes the level of electoral democracy in countries on a range of indicators, including:
- Free and fair elections
- Rule of law
- Alternative sources of information and association
- Freedom of expression
Countries are assigned a score on a scale from 0 to 1, with higher scores indicating a higher level of democracy. Each is also categorized into four types of functional government, from liberal and electoral democracies to electoral and closed autocracies.
Which Countries Have Declined the Most?
The EDI found that numerous countries around the world saw declines in democracy over the past two decades. Here are the 10 countries that saw the steepest decline in EDI score since 2010:
Country | Democracy Index (2010) | Democracy Index (2022) | Points Lost |
---|---|---|---|
๐ญ๐บ Hungary | 0.80 | 0.46 | -34 |
๐ต๐ฑ Poland | 0.89 | 0.59 | -30 |
๐ท๐ธ Serbia | 0.61 | 0.34 | -27 |
๐น๐ท Turkey | 0.55 | 0.28 | -27 |
๐ฎ๐ณ India | 0.71 | 0.44 | -27 |
๐ฒ๐ฑ Mali | 0.51 | 0.25 | -26 |
๐น๐ญ Thailand | 0.44 | 0.20 | -24 |
๐ฆ๐ซ Afghanistan | 0.38 | 0.16 | -22 |
๐ง๐ท Brazil | 0.88 | 0.66 | -22 |
๐ง๐ฏ Benin | 0.64 | 0.42 | -22 |
Central and Eastern Europe was home to three of the countries seeing the largest declines in democracy. Hungary, Poland, and Serbia lead the table, with Hungary and Serbia in particular dropping below scores of 0.5.
Some of the world’s largest countries by population also decreased significantly, including India and Brazil. Across most of the top 10, the “freedom of expression” indicator was hit particularly hard, with notable increases in media censorship to be found in Afghanistan and Brazil.
Countries Becoming More Democratic
Here are the 10 countries that saw the largest increase in EDI score since 2010:
Country | Democracy Index (2010) | Democracy Index (2022) | Points Gained |
---|---|---|---|
๐ฆ๐ฒ Armenia | 0.34 | 0.74 | +40 |
๐ซ๐ฏ Fiji | 0.14 | 0.40 | +26 |
๐ฌ๐ฒ The Gambia | 0.25 | 0.50 | +25 |
๐ธ๐จ Seychelles | 0.45 | 0.67 | +22 |
๐ฒ๐ฌ Madagascar | 0.28 | 0.48 | +20 |
๐น๐ณ Tunisia | 0.40 | 0.56 | +16 |
๐ฑ๐ฐ Sri Lanka | 0.42 | 0.57 | +15 |
๐ฌ๐ผ Guinea-Bissau | 0.41 | 0.56 | +15 |
๐ฒ๐ฉ Moldova | 0.59 | 0.74 | +15 |
๐ณ๐ต Nepal | 0.46 | 0.59 | +13 |
Armenia, Fiji, and Seychelles saw significant improvement in the autonomy of their electoral management bodies in the last 10 years. Partially as a result, both Armenia and Seychelles have seen their scores rise above 0.5.
The Gambia also saw great improvement across many election indicators, including the quality of voter registries, vote buying, and election violence. It was one of five African countries to make the top 10 most improved democracies.
With the total number of democracies and non-democracies almost tied over the past four years, it is hard to predict the political atmosphere in the future.
