“We documented the partisan trade-off bias across five studies using online samples of a total of 1,236 participants, a mix of Republicans and Democrats. As an example, in one of our studies participants were randomly assigned to view a set of policy trade-offs, some proposed by Republicans and some proposed by Democrats. The policies dealt with taxes, environmental regulation, gun control and voting rights. Participants then rated how intentional they perceived the negative side effects of each policy to be. The more participants identified with the Republican Party, the more intentional they perceived the side effects of the Democratic-proposed policies to be, and the more participants identified with the Democratic Party, the more intentional they perceived the side effects of Republican-proposed policies to be.
In a nutshell, our studies showed that the negative side effects associated with different policy trade-offs are not interpreted by opponents as side effects at all, but as intended goals of the policy.”
“The good news is that by identifying the partisan trade-off bias, our research points a path forward: Policymakers who pay more attention to this bias might be better equipped to achieve compromise. This means that rather than focusing only on the main goal of a policy, they need to communicate clearly to the public what is intentional and what is a regrettable side-effect of that goal.”
