Fran and Sandra are identical twin sisters. They both just had their first child. Although neither had incredibly strong opinions on the topic, Fran tended to be a bit more skeptical about the safety of vaccines, while Sandra tended to think they were probably safe. Fran then started to hang out with a group of other new mothers who also tended to be slightly skeptical about the safety of vaccines. Sandra started to spend more time with a group of other new mothers who tended to think that vaccines were pretty safe. Six months later, Fran and Sandra’s opinions had completely diverged. Fran was now insistent that vaccines were unsafe, while Sandra was completely insistent that they were safe. What explains the difference between the sisters?

Jada is a researcher interested in Americans’ beliefs about gun violence. She knows that mass shootings, in particular those that involve the use of rifles of some sort, are highly publicized in the news media. Meanwhile, shootings involving handguns are much less publicized comparatively speaking. Jada asks 1000 participants to estimate the number of homicides (murders) committed with rifles and handguns respectively in the United States per year. She finds that participants dramatically overestimate the number of homicides committed with rifles as compared to the number of homicides committed with handguns. Jada’s findings are consistent with what decision-making issue?
