The human brain is capable of incredible things, but it’s also extremely flawed at times.
Science has shown that we tend to make all sorts of mental mistakes, called “cognitive biases”, that can affect both our thinking and actions. These biases can lead to us extrapolating information from the wrong sources, seeking to confirm existing beliefs, or failing to remember events the way they actually happened!
To be sure, this is all part of being humanโbut such cognitive biases can also have a profound effect on our endeavors, investments, and life in general.
For this reason, today’s infographic from DesignHacks.co is particularly handy. It shows and groups each of the 188 known confirmation biases in existence.
What is a Cognitive Bias?
Humans have a tendency to think in particular ways that can lead to systematic deviations from making rational judgments.
These tendencies usually arise from:
- Information processing shortcuts
- The limited processing ability of the brain
- Emotional and moral motivations
- Distortions in storing and retrieving memories
- Social influence
Cognitive biases have been studied for decades by academics in the fields of cognitive science, social psychology, and behavioral economics, but they are especially relevant in today’s information-packed world. They influence the way we think and act, and such irrational mental shortcuts can lead to all kinds of problems in entrepreneurship, investing, or management.
Cognitive Bias Examples
Here are five examples of how these types of biases can affect people in the business world:
1. Familiarity Bias: An investor puts her money in “what she knows”, rather than seeking the obvious benefits from portfolio diversification. Just because a certain type of industry or security is familiar doesn’t make it the logical selection.
2. Self-Attribution Bias: An entrepreneur overly attributes his company’s success to himself, rather than other factors (team, luck, industry trends). When things go bad, he blames these external factors for derailing his progress.
3. Anchoring Bias: An employee in a salary negotiation is too dependent on the first number mentioned in the negotiations, rather than rationally examining a range of options.
4. Survivorship Bias: Entrepreneurship looks easy, because there are so many successful entrepreneurs out there. However, this is a cognitive bias: the successful entrepreneurs are the ones still around, while the millions who failed went and did other things.
5. Gambler’s Fallacy: A venture capitalist sees a portfolio company rise and rise in value after its IPO, far behind what he initially thought possible. Instead of holding on to a winner and rationally evaluating the possibility that appreciation could still continue, he dumps the stock to lock in the existing gains.

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.
