Why Democracy Lives and Dies by Math

“Math is power” is the tag line of a new documentary, “Counted Out,” currently making the rounds at festivals and community screenings. (It will have a limited theatrical release next year.) The film explores the intersection of mathematics, civil rights and democracy. And it delves into how an understanding of math, or lack thereof, affects society’s ability to deal with its most pressing challenges and crises — health care, climate, misinformation, elections.

“When we limit access to the power of math to a select few, we limit our progress as a society,” said Vicki Abeles, the film’s director and a former Wall Street lawyer.

Ms. Abeles was spurred to make the film in part in response to an anxiety about math that she had long observed in students, including her middle-school-age daughter. She was also struck by the math anxiety among friends and colleagues, and by the extent to which they tried to avoid math altogether. She wondered: Why are people so afraid of math? What are the consequences?

One of many mathematicians who share their perspectives in the film is Ismar Volic, a professor at Wellesley College and a founder, in 2019, of the Institute for Mathematics and Democracy. He is also the author of “Making Democracy Count: How Mathematics Improves Voting, Electoral Maps and Representation.”

Dr. Volic grew up in Bosnia-Herzegovina, a country that in the early 1990s went through “a horrific war,” he said. “I am familiar with what collapse of democracy can lead to.” He saw parallels between what happened in Bosnia and what was happening in the United States and around the world. “That has driven me in the last few years, understanding the mechanics of democracy, the infrastructure of democracy, which is very much mathematical,” he said.
