Critical Thinking Day!

I've been seeing a meme make its rounds on the Book of Faces and other places. It essentially states: "April Fool's Day: The one day when people critically evaluate what they read." Sadly, this is not true for everyone even today. But why do people seem to find critical thinking so unnecessary?

Turns out most people have a tendency to be cognitively lazy. Forming new connections in the brain--and changing those connections--takes a lot of work, and people don't like work. It becomes especially difficult when connections have been formed and used the same way for years. However--it can still be done!
