Problem: Carlina watches the news and sees a headline that a plane has disappeared in the Indian Ocean, presumed crashed. Six months later, the top news story is that a plane traveling from Russia to Turkey crashes. Seven months after that, the top story is that a privately chartered jet carrying a soccer team crashes in South America. She cancels her plans to fly to Europe for vacation, declaring to her husband, "We're not going to Europe on vacation anymore, there are plane crashes practically every day, it's not safe to fly!" What phenomenon in Carlina's environment is encouraging her inaccurate conclusions?
