But the “by definition” part seems incorrect. Nothing in the definition of “Super Earth” indicates superior habitability.

  The author goes on to explain why super earths are a good place to look for habitable planets. It’s the entire point of the article. Planets meeting this definition also tend to have other characteristics as well.

  It may not be worded well but it does state why. Planets of this size are more likely to be geologically active, a sufficient size to retain an atmosphere thick enough for life, a strong enough magnetic field, etc.,. Just due to their size, they are better suited to support life then (at least as we know the conditions necessary). I mean between the other options - planets so small they're basically rocks in space and giant gas planets with a bunch of other issues - it seems this classification of planets indeed offer superior habitability.
