Fannie Mae’s latest National Housing Survey found that Americans are feeling more positive about the economy, and are happy to make predictions about it.

More people expect mortgage rates to go up and housing prices to go down over the next year, for example. And — based on what I couldn’t tell you — “51 percent of respondents now say it would be easy to get a mortgage.”

Props for the enthusiasm, but before we buy into our own prediction skills, keep in mind that more than one in five Americans think the sun revolves around the Earth. (Seriously.)
