Here's a helpful quiz from MassMutual, and insurance and investment company, about the basics of Social Security. People are not doing really well on this quiz. This means one of two things. Either people who take Social Security quizzes are less informed than most, or most people don’t know as much as they think they do about Social Security. This is pretty likely, because even regular old retire-and-get-paid Social Security is a little more confusing than we'd all like to think.
