In a world where political views are often set in stone, it's interesting to see how unexpected supporters can shake things up. This is not about dramatic changes, but about how people's opinions on policies can shift when someone from their own group supports something unusual. For instance, if a liberal backs gun rights or a conservative supports abortion rights, it can make others in their group think twice. This is not just about changing minds within the group, but also about influencing those on the other side.

The big question is, does this kind of unexpected support persuade the ingroup to back the policy, make the outgroup less likely to support it, or both? And if it does both, is the impact the same for both groups? This is what a series of studies in Brazil aimed to find out. Brazil was chosen because it is a highly polarized society, making it a great place to test these ideas. The studies involved over 3, 380 participants and looked at a range of policies, from abortion to gun rights and welfare programs. The findings were clear: when someone from within a group supports a policy that most of their group opposes, it can persuade their own group to support it and, to a lesser extent, make the opposing group less likely to support it. This helps to reduce the differences in policy attitudes between the groups.

The studies showed that this effect happens across different policies and types of supporters, whether they are political leaders or regular citizens. The change in attitudes happens even if beliefs about the policy's benefits stay the same. However, if people start to question whether the supporter is really part of their group, the effect disappears. This suggests that the supporter's credibility and the group's norms play a big role in how persuasive they can be.

One important thing to note is that the studies were conducted in Brazil, a country known for its strong political divisions. This means that the results might not apply in the same way to other countries with different political landscapes. However, the findings do provide a interesting look at how unexpected support can influence policy attitudes and reduce intergroup differences. It's a reminder that even in a polarized world, unexpected allies can make a difference.

The studies also highlight the role of source credibility, perceived ingroup norms, and perceived policy extremity in shaping these persuasive effects. In other words, who is saying what matters just as much as what they are saying. This is a critical point to consider when thinking about how to influence policy attitudes and reduce intergroup differences. It's not just about the message, but also about the messenger.
