A big data study spanning more than a century

Researchers from institutions including Columbia University recently analyzed more than 8 million speeches taken from a range of US Congressional and local government debates over 150 years. The content extended to national legislatures as well as municipal general meetings. With the help of machine learning tools and natural language processing techniques, they were able to detect language patterns and transformations at a level of detail never seen before.

Unlike traditional linguistic studies that only examine key figures or high-level debates, this study included speeches from rank-and-file council members, senators, and local officials. By collecting more than 100 data sets, the team examined a continuous stream of political and civic language from 1873 through the 21st century. The result was one of the largest linguistic studies of political discourse ever conducted in the United States.

Public speeches have become more personalized over time

One of the study’s key findings is the way public discourses in the United States have become more personalized. Over the past decades, politicians have shifted from using formal and detached language to adopting more conversational tones. Words such as “I,” “me,” and “you” appear frequently, indicating a move toward individual expression and direct engagement with audiences. This change represents a strategic adaptation aimed at establishing deeper emotional connections with voters.

Historically, political speeches have emphasized collective action, institutional authority, and formal articulation. Phrases such as “the American people” or “our fellow citizens” dominated the speech. In contrast, modern speeches tend to focus on personal views and direct appeals. These changes suggest that politicians may strive to appear more realistic and realistic, which is consistent with broader cultural expectations of transparency and emotional expression.

Increased use of emotion-driven language

Researchers noted a general rise in the use of emotional words such as “hope,” “fear,” and “love.” Words expressing personal feelings and emotional states have become common, even in settings such as congressional hearings or city council meetings, where such language was previously rare. This evolution complements the ongoing personalization trend, where emotional language helps leaders build trust and align values with their audiences.

The use of emotional language also reflects broader shifts in public expectations. Citizens today tend to expect leaders who not only deliver strong policies but also demonstrate empathy and emotional intelligence. This style of communication is now seen as a political asset rather than a personal skill.

Localization of political discourse

One of the most interesting findings of the study is the local nature of modern political discourses. Local officials have increasingly focused on issues that directly affect their communities. Rather than discussing broad national concerns, today’s speeches often include references to neighborhood conditions, traffic, safety concerns, and local school systems. This level of privacy has increased dramatically over the past 50 years.

Targeted vocabulary helps politicians communicate more effectively with their audiences, making their words more relevant to voters. This also reflects a trend where political campaigns zoom in on very local issues to secure voter support. As a result, sermons now contain geographical references, local landmarks, and familiar cultural symbols to resonate more deeply with listeners.

The rise of informal vocabulary and simplified syntax

The study observed a structural shift in sentence structure and word choice. Today’s speeches contain shorter sentences, basic word structures, and more informal phrasing. This linguistic simplification improves accessibility to a wider audience and allows politicians to reach a greater number of people across different educational levels.

Earlier speeches typically featured complex sentence structures and complex vocabulary, which was standard at a time when oratory skill was directly linked to political credibility. These stylistic choices rewarded those who followed formal rhetorical conventions. Contemporary speeches are now less concerned with performance and more concerned with clarity and relatability.

This linguistic change may also be influenced by how people consume media today. The emergence of digital platforms, short videos and social media posts encourages clear, concise and engaging messages. Leaders are now taking into account the reach and shareability of their speeches across multiple formats.

Implications for political strategy and public trust

These shifts in speech patterns are more than just linguistic curiosities, they have real consequences for political behavior and public trust. Greater personalization, emotional richness, and accessible language help build a stronger perception of transparency. Voters are more likely to trust politicians who appear honest and emotionally relatable.

However, this trend can also pose risks. The increasing use of emotional language opens the door to manipulative rhetoric, where appeals to fear or emotion overwhelm logical arguments. The erosion of formal structures can weaken the seriousness or perceived attractiveness of political institutions, especially if leaders rely heavily on informal or informal discourse.

The unprecedented scale of this study was made possible by machine learning and natural language processing techniques. The researchers used neural networks capable of identifying not only words, but also emotions, context, and nuances of rhetoric. Algorithms have analyzed gigabytes of textual data to extract meaningful insights from decades of discourse.

This represents a major shift in how linguistic and historical research is conducted. Instead of relying on limited samples or manual coding, machine learning enables broader and more precise analysis. As artificial intelligence and computational linguistics continue to evolve, expect more transformative insights from massive data sets around the world.

What this means for the future of political communication

The evolution revealed in this study strongly suggests that political communication will continue to adapt in response to culture, technology, and voter behavior. Personalization, localism, and emotional connection are not short-term trends, but rather reflect deep-rooted changes in how leaders connect with their communities.

As future politicians ascend to the public stage, they will likely refine these new standards even further. Letters may become increasingly standardized, that is, customized for digital environments, adapted for interpretation, and designed with SEO in mind. This study not only reveals what has changed, but also charts the course for what comes next.

Citizens and political thinkers now have data-driven confirmation of patterns they may have only sensed intuitively. By understanding how speech shapes perception, we all gain a better understanding of how ideas become embedded in public consciousness. For anyone interested in language, politics, or social change, this study provides a valuable lens for observing American history in action.
