What are the two major shortfalls of definitions of leadership according to the authors.

They don't tell us where leadership resides and they don't explain how leadership is acco$]$nplished$.$

They don't explain what is meant by influence, nor what is meant by goals.

They don't tell us the traits good leaders should possess, nor the traits good followers should possess.

They tend to be culturally biased and leader$-$centric.
