11 Cognitive Biases That Influence Political Outcomes
Cognitive Biases in the Political Arena
With the 2020 U.S. presidential election fast approaching, many people will be glued to the 24-hour news cycle to stay up to date on political developments. Yet, when searching for facts, our own cognitive biases often get in the way.
If this isn’t problematic enough, third parties can also take advantage of these biases to influence our thinking. The media, for example, can exploit our tendency to assign stereotypes to others by only providing catchy, surface-level information. Once established in our minds, these generalizations can be tough to shake off.
Such tactics can have a powerful influence on public opinion if applied consistently to a broad audience. To help us avoid these mental pitfalls, todayโs infographic from PredictIt lists common cognitive biases that influence the realm of politics, beginning with the “Big Cs”.
The First C: Confirmation Bias
People exhibit confirmation bias when they seek information that only affirms their pre-existing beliefs. This can cause them to become overly rigid in their political opinions, even when presented with conflicting ideas or evidence.
When too many people fall victim to this bias, progress towards solving complex sociopolitical issues is thwarted. Thatโs because solving these issues in a bipartisan system requires cooperation from both sides of the spectrum.
A reluctance towards establishing a common ground is already widespread in America. According to a 2019 survey, 70% of Democrats believed their partyโs leaders should “stand up” to President Trump, even if less gets done in Washington. Conversely, 51% of Republicans believed that Trump should “stand up” to Democrats.
In light of these developments, researchers have conducted studies to determine if the issue of confirmation bias is as prevalent as it seems. In one experiment, participants chose to either support or oppose a given sociopolitical issue. They were then presented with evidence that was conflicting, affirming, or a combination of both.
In all scenarios, participants were most likely to stick with their initial decisions. Of those presented with conflicting evidence, just one in five changed their stance. Furthermore, participants who maintained their initial positions became even more confident in the superiority of their decisionโa testament to how influential confirmation bias can be.
The Second C: Coverage Bias
Coverage bias, in the context of politics, is a form of media bias where certain politicians or topics are disproportionately covered. In some cases, media outlets can even twist stories to fit a certain narrative.
For example, research from the University of South Florida analyzed media coverage on President Trump’s 2017 travel ban. It was discovered that primetime media hosts covered the ban through completely different perspectives.
Each host varied drastically in tone, phrasing, and facts of emphasis, […] presenting each issue in a manner that aligns with a specific partisan agenda.
โJosepher, Bryce (2017)
Charting the ideological placement of each source’s audience can help us gain a better understanding of the coverage bias at work. In other words, where do people on the left, middle, and right get their news?
The horizontal axis in this graphic corresponds to the Ideological Consistency Scale, which is composed of 10 questions. For each question, respondents are assigned a โ-1โ for a liberal response, โ+1โ for a conservative response, or a โ0โ for other responses. A summation of these scores places a respondent into one of five categories:
Ideological Category | Ranking |
---|---|
Consistently conservative | +7 to +10 |
Mostly conservative | +3 to +6 |
Mixed | -2 to +2 |
Mostly liberal | -6 to -3 |
Consistently liberal | -10 to -7 |
Overcoming coverage biasโwhich dovetails into other biases like confirmation biasโmay require us to follow a wider variety of sources, even those we may not initially agree with.
The Third C: Concision Bias
Concision bias is a type of bias where politicians or the media selectively focus on aspects of information that are easy to get across. In the process, more nuanced and delicate views get omitted from popular discourse.
A common application of concision bias is the use of sound bites, which are short clips that can be taken out of a politicianโs speech. When played in isolation, these clips may leave out important context for the audience.
Without the proper context, multi-faceted issues can become extremely polarizing, and may be a reason for the growing partisan divide in America. In fact, there is less overlap in the political values of Republicans and Democrats than ever previously measured.
In 1994, just 64% of Republicans were more conservative than the median Democrat. By 2017, that margin had grown considerably, to 95% of Republicans. The same trend can be found on the other end of the spectrum. Whereas 70% of Democrats were more liberal than the median Republican in 1994, this proportion increased to 97% by 2017.
Overcoming Our Biases
Achieving full self-awareness can be difficult, especially when new biases emerge in our constantly evolving world. So where do we begin?
Simply remembering these mental pitfalls exist can be a great startโafter all, we can’t fix what we don’t know. Individuals concerned about the upcoming presidential election may find it useful to focus their attention on the Big Cs, as these biases can play a significant role in shaping political beliefs. Maintaining an open mindset and diversifying the media sources we follow are two tactics that may act as a hedge.

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 Tรผrkiye | 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.
