When it comes to judgment, the group is not inherently superior to the individual. [Sometimes, all of us are dumber than one of us.] When forming a group for action, it is important that personalities and proclivities be considered because the little things will ultimately mean a great deal, regardless of how impressive the credentials or backgrounds.
This is not a group of individuals as much as it is a group of relationships. To assume that productive relationships will naturally ensue is to believe in magic.
And it is not wise to rely on magic.
