Partisan hostility in the United States is at a fever pitch and is a dominant theme in the 2024 election cycle. But how much does it matter to everyday life in America? What is really at stake?


James Druckman, a professor of political science at the University of Rochester who is widely considered one of the country's foremost experts on political polarization and its impact on American democracy, is poised to answer those questions and back up his conclusions with data. 


His latest book, Partisan Hostility and American Democracy: Explaining Political Divisions and When They Matter, outlines the potential consequences of extreme partisan animus by distilling empirical evidence gathered between 2019 and 2021. The upshot? Partisan hostility alone is unlikely to lead to the collapse of American democracy. But it nonetheless has a deleterious effect on democracy and could erode democratic institutions and functioning over time.


In the end, the book concludes, American democracy hinges more on how political leaders respond to the polarization than the polarization itself. 


Druckman has been cited by The New York Times columnist Thomas Edsall as among the political scientists in the country "working on getting us to hate one another less."

Research Matters: Can Neurons Transmit Light?

Neurons, the cells in brains and spinal cords that make up the central nervous system, communicate by firing electrical pulses. But scientists have found hints that neurons may transmit light as well, which would profoundly change our current understanding of how the nervous system works. Researchers from the University of Rochester have begun an ambitious project to study if living neurons can transmit light through their axons — the long, tail-like nerve fibers of neurons that resemble optical fibers. “There are scientific papers offering indications that light transport could happen in neuron axons, but there’s still not clear experimental evidence,” says the principal investigator, Pablo Postigo, a professor at the university's Institute of Optics. “Scientists have shown that there is ultra-weak photon emission in the brain, but no one understands why the light is there.” If light is at play and scientists can understand why, it could have major implications for medically treating brain diseases and drastically change the way physicians heal the brain.

Why generative AI 'hallucinates' and makes up stuff

Generative artificial intelligence tools, like OpenAI’s GPT-4, are sometimes full of bunk. Yes, they excel at tasks involving human language, like translating, writing essays, and acting as a personalized writing tutor. They even ace standardized tests. And they’re rapidly improving. But they also “hallucinate,” which is the term scientists use to describe when AI tools produce information that sounds plausible but is incorrect. Worse, they do so with such confidence that their errors are sometimes difficult to spot. Christopher Kanan, an associate professor of computer science with an appointment at the Goergen Institute for Data Science and Artificial Intelligence at the University of Rochester, explains that the reasoning and planning capabilities of AI tools are still limited compared with those of humans, who excel at continual learning. “They don’t continually learn from experience,” Kanan says of AI tools. “Their knowledge is effectively frozen after training, meaning they lack awareness of recent developments or ongoing changes in the world.” Current generative AI systems also lack what’s known as metacognition. “That means they typically don’t know what they don’t know, and they rarely ask clarifying questions when faced with uncertainty or ambiguous prompts,” Kanan says. “This absence of self-awareness limits their effectiveness in real-world interactions.” Kanan is an expert in artificial intelligence, continual learning, and brain-inspired algorithms who welcomes inquiries from journalists and knowledge seekers. He recently shared his thoughts on AI with WAMC Northeast Public Radio and with the University of Rochester News Center. Reach out to Kanan by clicking on his profile.

Should I use AI to write my college entrance essay?

With the rapid advancement of artificial intelligence tools such as generative pre-trained transformers, or GPTs, high school students may be tempted to use the tools to perfect their college applications, particularly their entrance essay. Robert Alexander, a vice provost and the dean of enrollment management at the University of Rochester, cautions prospective college students from relying too heavily on AI tools in their applications. “The sentiment among college admissions professionals is that while AI tools may be helpful in generating essay topics and refining or editing students’ writing, we discourage their use to compose application essays or short answers because AI stifles an applicant’s authentic voice,” Alexander says. That personal voice becomes paramount when admissions officers are sifting through applications and considering how each student will contribute to the campus community and fit into the incoming class. “No college or university is trying to admit perfectly identical automaton students,” Alexander says. “At the University of Rochester, for instance, we’re not looking for 1,300 perfect students. We’re trying to craft the perfect class of 1,300 very different and highly-imperfect, but great-fit students.” The goal, he says, is to invite great students, inclusive of their imperfections, and guide them on a transformative journey through their next four years. “Colleges want students to come in with a growth mindset and potential,” Alexander says. “So, if students think they can use AI to help make their application ‘perfect,’ I think they’re chasing the wrong brass ring.” Alexander is an expert in undergraduate admissions and enrollment management who speaks on the subjects to national audiences and whose work has been published in national publications.
