To be robust, or to delegate, that is the question...

"A growing body of research suggest that even the smartest people tend to seek out evidence that confirms what they already think, rather than new information that would give them a more robust view of reality.
     "It is also tempting to run with the herd.  Even on the most important issues of the day, we often adopt the views of our friends, family, and colleagues.  On some level, this makes sense:  it is easier to fall in line with what your family and friends think than to find new family and friends!   But running with the herd means we are quick to embrace the status quo, slow to change our minds, and happy to delegate our thinking."
