Congressional speeches have shifted to not based on evidence

The language used by US Congress members in the debate has increasingly included words like “fake,” and “suspectful” for words like “proof,” and “reason.”
This linguistic trend, away from evidence in support of intuition, was revealed in an artificial intelligence analysis of millions of Congress speech transcripts. It also says it coincides with both the larger political polarization in Congress and the decline in the number of laws enacted through Congress. Stephen Lewandowski At the University of Bristol, UK.
“We can think of the truth as something that can be achieved based on an analysis of evidence, or we can think of it as the result of intuition or “gut sensation,” says Lewandowsky. “The concepts of integrity and truth are expressed in how we use everyday language.”
Adapting the ready-made AI language model, Lewandowsky and his colleagues analyzed the words used in the transcripts of eight million council speeches given between 1879 and 2022. They then calculated scores indicating whether a particular parliamentary speech was leaning towards evidence or intuition.
They found that since the 1970s, Congress has increasingly supported languages ​​based on intuition rather than evidence-based languages. Before that, in the golden age of 1899-1901, and in the Great Repression of 1933-1935, intuitive language also skyrocketed.
“The findings fit the other impressions of anti-intellectualism, populism and rejection of science experts over the last decades.” John Jost At New York University.
The specific strength of the research is not only tracking frequency, but also assessing the context in which the words are displayed, he says Renata Nemet At the University of Eötvös Loránd, Hungary. “These models can capture deeper and often subtle connections between words, even reflecting cultural meanings and social relationships,” she says.
Second, Lewandowsky and his colleagues will look for similar language shifts for individual lawmakers in both Congress speeches and social media posts. They also seek to compare similar trends among other parliaments throughout history, including speeches from lawmakers from Italy and Germany.
