A directly elected upper house is more effective  When an upper house is directly elected, it will be perceived to be more legitimate by the public, because the public sees their political views directly translated into a legislative branch, albeit in a different way than the lower house. This enhanced legitimacy will help the upper house in performing their constitutional duties: whenever the upper house disagrees with either the lower house or the executive, the upper house can now strengthen their position by pointing to the public support it has.
