Engineering an advantage in debates

Researchers at the University of Michigan have developed an algorithm that can analyze and measure the amount that one candidate linguistically matches their opponent and have found that matching your opponent in a debate leads to higher polling numbers.

Most of the time, a presidential debate can be hard to call one way or the other. It’s difficult to put a score to something that is ultimately decided in the minds of the vastly diverse American public.

However, computer science researchers at the University of Michigan have developed an algorithm that can analyze and measure the amount that one candidate linguistically matches their opponent and have found that matching your opponent in a debate leads to higher polling numbers.

Transcripts were collected and evaluated from debates dating back to 1976, and the researchers were able to determine that linguistically matching your opponent has an important effect on the perception of a third party viewer watching the interaction. Matching an opponent linguistically takes advantage of a concept called processing fluency, the act of using similar words as an opponent in order to make the information more digestible for the viewer. In the case of two candidates debating for the presidency, the ability to mimic your opponent could prove to be an important contributor to an eventual victory.
