Batten Professor Craig Volden no longer designs spacecraft—instead, he’s engineering a metric to combat political gridlock.
Center for Effective Lawmaking, which has brought together a team of top policy experts from around the country to study what makes certain legislators more successful.
“The Center for Effective Lawmaking exemplifies the promise of a public research university,” said Jay Shimshack, Batten’s associate dean for academic affairs. “The center is generating new knowledge, translating and disseminating results to the public, and making a difference in the real world.”
Some of the center’s findings are to be expected—experienced lawmakers tend to score higher, for example. But other discoveries, such as the heightened effectiveness of minority-party women, are more surprising. This year, Volden and Wiseman further extended the scope of their research when they scored members of state legislatures. Their paper presenting these results was recently named the best paper of 2020 on state politics and policy by the American Political Science Association.
While the new ratings shed light on the effectiveness of lawmakers in individual states, they have important implications at the national level as well. Volden and Wiseman found that in cases where the legislatures were more evenly divided along party lines, lawmakers (especially in the minority party) frequently struggled to advance bills into law—a situation that reflects our current Congress.
“In really closely divided legislatures, the majority party doesn’t want the minority party to succeed at all and tends to dismiss their ideas,” Volden said. Both parties become preoccupied with gaining the upper hand, turning their focus away from governing and toward concerns about elections. “That’s really unhealthy,” he added.
The Center for Effective Lawmaking has recently put a heavier emphasis on engagement: hosting high-profile events, advertising the research it leads and establishing the Building a Better Congress Project, which seeks to identify the traits of effective lawmakers and opportunities for congressional reforms. The center also produces materials that explain how to legislate more effectively.
Although Volden’s work with Wiseman on the scores has garnered much scholarly attention, he especially enjoys moments when non-academics—lawmakers and the general public—take interest. Senator Amy Klobuchar is a recent example. After Volden and Wiseman’s metric identified her as the most effective Democratic senator in the 115th Congress, her presidential campaign advertised her high score on T-shirts during the Iowa caucuses.
The center also receives many calls from members of Congress asking how they can improve their scores. “Bridging the academic and policy worlds, connecting the work of scholars to the day-to-day experiences of practitioners—that has felt deeply rewarding,” Volden said.
In many ways, political gridlock on the Hill has become the norm, and party differences can begin to feel insurmountable. But Volden’s research approaches the problem from a new angle. Shimshack believes his conviction that good leadership can be measured and quantified sets Volden’s work apart.
“Craig and his colleagues are showing that we can use data to promote accountability in lawmaking,” he said. “They are conducting frontier research that is changing the national conversation.”
“What we’re doing is not rocket science,” Volden added, “but to us, it feels even more fulfilling.”
