Knowing about others’ political views interferes with the ability to learn about their competency in unrelated tasks, leading to suboptimal information-seeking decisions and errors in judgement

Abstract: On political questions, many people are especially likely to consult and learn from those whose political views are similar to their own, thus creating a risk of echo chambers or information cocoons. Here, we test whether the tendency to prefer knowledge from the politically like-minded generalizes to domains that have nothing to do with politics, even when evidence indicates that person is less skilled in that domain than someone with dissimilar political views. Participants had multiple opportunities to learn about others’ (1) political opinions and (2) ability to categorize geometric shapes. They then decided to whom to turn for advice when solving an incentivized shape categorization task. We find that participants falsely concluded that politically like-minded others were better at categorizing shapes and thus chose to hear from them. Participants were also more influenced by politically like-minded others, even when they had good reason not to be. The results demonstrate that knowing about others’ political views interferes with the ability to learn about their competency in unrelated tasks, leading to suboptimal information-seeking decisions and errors in judgement. Our findings have implications for political polarization and social learning in the midst of political divisions.

Experiential or Material Purchases? Social Class Determines Purchase Happiness. Individuals of higher social class, whose abundant resources make it possible to focus on self-development and self-expression, were made happier by experiential over material purchase

Experiential or Material Purchases? Social Class Determines Purchase Happiness. Jacob C. Lee, Deborah L. Hall, Wendy Wood. Psychological Science, https://doi.org/10.1177/0956797617736386

Abstract: Which should people buy to make themselves happy: experiences or material goods? The answer depends in part on the level of resources already available in their lives. Across multiple studies using a range of methodologies, we found that individuals of higher social class, whose abundant resources make it possible to focus on self-development and self-expression, were made happier by experiential over material purchases. No such experiential advantage emerged for individuals of lower social class, whose lesser resources engender concern with resource management and wise use of limited finances. Instead, lower-class individuals were made happier from material purchases or were equally happy from experiential and material purchases.

Before the 2016 election, Republicans showed greater in-group favoritism than Democrats, who treated others equally, regardless of their political affiliation; after, Republicans no longer showed in-group favoritism, while Democrats showed out-group derogation

When the tables are turned: The effects of the 2016 U.S. Presidential election on in-group favoritism and out-group hostility. Burak Oc, Celia Moore, Michael R. Bashshur. PLOS, May 24, 2018, https://doi.org/10.1371/journal.pone.0197848

Abstract: The outcome of the 2016 U.S. Presidential election was a big surprise to many, as the majority of polls had predicted the opposite outcome. In this two-stage cross-sectional study, we focus on how Democrats and Republicans reacted to this electoral surprise and how these reactions might have influenced the way they allocated resources to each other in small groups. We find that, before the election, Republicans showed greater in-group favoritism than Democrats, who treated others equally, regardless of their political affiliation. We then show that Democrats experienced the election outcome as an ego shock and, in the week following the election, reported significantly higher levels of negative emotions and lower levels of self-esteem than Republicans. These reactions then predicted how individuals’ decided to allocate resources to others: after the election, Republicans no longer showed in-group favoritism, while Democrats showed out-group derogation. We find these decisions when the tables were turned can be partially explained by differences in participants’ state self-esteem.
