Being smarter is usually associated with success – intelligence has been found to have a positive relationship with leadership effectiveness - however this research shows the relationship flattens and even reverses at a certain level (IQ around 120).

This research supports what we are already applying– ability only tells us one part of the story and it is often not necessary to use overly high cut off scores. The use of personality assessments and interpretation of what this means for leadership styles, helps us make better informed recommendations for leadership effectiveness.
