OnAir Post: Polarization and Extremism
About
Source: Gemini AI Overview
Key characteristics
- Ideological Divergence
This involves a widening gap between the policy positions of political parties and their supporters, according to National Institutes of Health (NIH). - Affective Polarization
This signifies a rise in negative emotions and hostility between different political groups, leading to feelings of distrust, dislike, and even animosity towards those with opposing viewpoints. - Partisan Sorting
This describes the tendency for individuals to align their social and cultural identities with their political affiliations, creating more distinct and antagonistic groups. - Elite Polarization
This refers to the ideological sorting and divergence among political leaders and elected officials, which can further fuel polarization among the public.
Causes
- Economic Inequality
Creating grievances and resentment, potentially increasing the potential for radicalization. - Misinformation and Disinformation
Spreading false narratives and amplifying divisions, says Salzburg Global. - Weak or Corrupt Political Institutions
Leading to a lack of legitimate mechanisms for resolving disputes, potentially increasing the likelihood of violence. - Social Media
Algorithms designed for engagement can amplify divisive content and create echo chambers, according to a Brookings report. - Shift in Party Composition
For example, the movement of Southern Conservatives from the Democratic Party to the Republican Party following the Civil Rights Act, making both parties more ideologically homogeneous, says Professor Jane Mansbridge.
Effects
- Erosion of Trust in Institutions
Undermining faith in democratic processes and governance. - Legislative Gridlock
Making it difficult for lawmakers to find common ground and pass legislation. - Negative Impacts on Mental and Physical Health
Increased stress, anxiety, and even physical health problems related to political events, according to a Psychology Today article. - Increased Social Divisions
Affecting relationships and leading to feelings of alienation. - Vulnerability to Extremism
Polarization can create an environment where extreme viewpoints become more appealing and normalized.
Political extremism
Key characteristics
- Rejection of Established Norms
Disregarding traditional political processes and institutions. - Promotion of Specific Ideologies
Often based on rigid interpretations of political, social, or religious principles. - Mistrust of Institutions and Facts
Dismissing information and sources that contradict their views. - Potential for Violence
Some extremist groups advocate for or use violence to achieve their goals, according to Virginia Commonwealth University.
Causes
- Perception of Threat and Fear
Seeing opposing groups or ideologies as existential threats, which can drive individuals towards extreme views and behaviors. - Social and Economic Inequality
Creating grievances that can be exploited by extremist ideologies. - Misinformation and Disinformation
Spreading false narratives and propaganda that can fuel extremist beliefs and actions. - Psychological Vulnerabilities
Certain psychological factors can make individuals more susceptible to radicalization. - Social Media
Algorithms and echo chambers can amplify extremist messages and facilitate recruitment.
Distinction between polarization and extremism
- Polarization refers to the widening gap between political views and the resulting tensions, whereas extremism involves holding beliefs at the fringes of acceptable political discourse, potentially advocating for violence or undermining democratic norms.
- Polarization can create a fertile ground for extremism, but not all polarized individuals are extremists.
- Extremism can be a manifestation of divergence, one of the forms of polarization, but it can also be distinct in its embrace of violence and rejection of democratic processes.

1. Undermining democracy and institutions
- Weakening of democratic norms
Extreme polarization can lead to the erosion of norms like respect for elections and the peaceful transfer of power. - Gridlock and ineffective governance
When political actors are unwilling to compromise, it becomes difficult for governments to function effectively and address important issues. - Rise of authoritarianism
In extreme cases, polarization can be exploited by authoritarian movements that seek to dismantle constitutional checks and consolidate power, according to the Center for American Progress.
2. Increased social fragmentation and distrust
- Erosion of social trust
Polarization breeds distrust between opposing political groups, which can undermine the ability of society to cooperate and work toward common goals. - Heightened social tensions
When groups become deeply divided along political lines, it can lead to increased social tensions and even the risk of violence. - Intensified political violence
A rise in extremist ideologies and distrust can increase the potential for political violence, targeting individuals or institutions, notes the Center for Strategic and International Studies.
3. Disinformation and threats to information integrity
- Spread of misinformation and fake news
Polarization creates an environment ripe for the spread of misinformation and disinformation, which can further inflame passions and distort public debate, says USC Today. - Filter bubbles and echo chambers
Social media algorithms can contribute to polarization by creating “filter bubbles” where individuals are primarily exposed to information that confirms their existing beliefs, limiting exposure to diverse perspectives. - Difficulty in distinguishing fact from fiction
The prevalence of misinformation makes it challenging for citizens to assess information critically and determine its veracity, impacting their ability to make informed decisions.
4. Other contributing factors and challenges
- Economic inequality
Research suggests a correlation between high levels of economic inequality and increased political polarization. - Changes in the media ecosystem
The rise of partisan media outlets and the amplifying effect of social media can contribute to polarization. - Weakening institutions and norms
Political actors may have incentives to prioritize their party’s platform over compromise, further widening the gap between opposing sides.
Innovations
Research and innovation efforts are actively exploring various approaches to address the escalating challenges of political polarization and extremism. A central theme revolves around understanding the underlying drivers and developing targeted interventions.
