Susan Drumm explains why cognitively diverse teams clash more: each person has blind spots others naturally see. The Enneagram can surface leadership styles and gaps, but hiring similar thinkers removes that coverage and increases risk.

The most cognitively diverse teams can have the most conflict because of this. As human beings, we think we're chameleons and can see 360 degrees, but we're humans that have a central vision and a peripheral vision. And where I point my focus of attention, that's what I see, that's what I'm motivated by. But there's something behind my head I can't see, and that's my blind spot. Now, now, in the model of the Enneagram, which is what we use to uncover your own and your team members leadership style, there's someone else who has the natural gift to look in the direction of your blind spot. But if I keep arguing that what I see is green and you're arguing that what you see is yellow, we never get anywhere. The most cognitively diverse teams can have the most conflict because of this, knowing that people then tend to hire people that think just like them. But that's a big mistake, because then no one on your team is looking in the direction of your blind spot.
