Do personality "tests" really reveal how people think and work?
And if so, can test-takers change their personalities to shore up weaknesses?
Two academics focusing on leadership studies, Roy Williams and Terrence Deal, use the Myers Briggs and another model of cognitive styles to examine leadership and managerial roles.
In their book, "When Opposites Dance: Balancing the Manager and Leader Within," Williams and Deal conclude that, while people are indeed predisposed to think and act in certain ways, the best executives consciously combine different personality attributes. This enables them to respond effectively to a variety of leadership situations.
When going outside or promoting within, it is always a good idea to evaluate the leadership style and capabilities of the job candidates.
There are a number of leadership self assessments available at www.SelfAssessmentCenter.com and directly from assessment publishers. Research reports on leadership styles are also available online for you to review---to get a feel for the best leadership personality for the job at hand. Here is a link to one research report that may prove helpful if you are looking for an early stage turnaround leader:
