Why do People Never Change Their Minds on Political Issues?

Why do people so rarely change their minds about political issues? It seems like every day fewer citizens are willing to alter their beliefs when it comes to their politics. Sarah Lubrano in a 2025 article for The Guardian echoes this claim, stating that “..arguments alone have no meaningful effect on people’s beliefs. And the implicit societal acceptance that they do is getting in the way of other, more effective forms of political thinking and doing.” But why is this? Well the root comes in the fact that taking on a policy or two of a candidate quickly turns into defining you as a person. Since politics have become such a defining part of one's personality, your friend groups and relationships can quickly be centered around your ideology, creating a filter bubble that is all too common among voters. Once you have built this castle around you, it becomes almost impossible to have those walls torn down. A study in 2019 by the National Bureau of Economic Research analyzed 200,000 respondents to see whether debates helped undecided or decided voters to make up or change their minds, and ultimately found no evidence that they did. In fact, people tend to alter their opinions to reflect the positions or actions of their favorite political candidate. For example, before Trump was convicted of a variety of charges in 2024, just 17% of Republicans believed felons should be able to be president. After he was convicted, that number rose to 58%. This is in no small part due to the social cost of leaving a party or changing beliefs, because with it comes the risk of losing friends or communities and even professional positions. So, instead of looking analytically at information, possibly leading to a change in opinion or position, most people choose to naturally look for information that supports what they already believe. This is supported through social media algorithms, which simply support what a viewer already believes. All-in-all, while people do change their minds about political issues, it often comes very slowly and through relationships, not flashy online debates.When belief is tied to your identity, steady, constant streams of other sides through relationships and connections ultimately determine your political leaning.
