It's not completely a false dichotomy.

A casual Google search says that "happy" == "feeling or showing pleasure or contentment".

The more informed you are, the more problems you will see and the less content you will be with the state of things. Problems aren't particularly conducive to happiness.

That said, ignorance is not necessarily bliss. It is better to be informed and be able to protect oneself from possible problems than it is to continue to pretend everything is fine and fall victim to eventual problems.
