A study analyzing patterns in online comments found that liberals and conservatives use different words to express similar ideas.
Liberals and conservatives often seem to speak different languages. A new study using artificial intelligence says that is now literally true.
Researchers at Carnegie Mellon University collected more than 86.6 million comments from more than 6.5 million users on 200,000 YouTube videos, then analyzed them using an AI technique normally employed to translate between two languages.
The researchers found that people on opposing sides of the political divide often use different words to express similar ideas. For instance, the term “mask” among liberal commenters is roughly equivalent to the term “muzzle” for conservatives. Similar pairings were seen for “liberals” and “libtards” as well as “solar” and “fossil.”
Ashique KhudaBukhsh, a project scientist at CMU involved with the study, says the polarization of American political discourse in recent years inspired him and colleagues to see if translation techniques might identify terms that were used in similar contexts by people with different views.
“We are practically speaking different languages—that’s a worrisome thing,” KhudaBukhsh says. “If ‘mask’ translates to ‘muzzle,’ you immediately know that there is a huge debate surrounding masks and freedom of speech.”
