Sometimes I think PhD's should be awarded to Groups or atleast Pairs of researchers.

Let the group find each other and defend a thesis. If the group breaks apart they loose their certification of expertise. And can reform and reprove it. Those who want to do things alone can, ofcourse do things the old way.

This would reduce the the unrealistic expectations on some folk who work better in groups, while allowing them to hone whatever skills they bring to the table.

Groups basically compensate for each others limitations and in the modern highly competitive world, with it's time/resource constraints and complex problems certifying individual expertise is looking over rated.
