Just started reading The Ten Faces of Innovation by Tom Kelley of IDEO fame. On the jacket there's a quote from Seth Godin '...there's a nugget on every page'.
This is true, so far.
In the intro Tom talks about 'The Devil's Advocate'.
This is the person WE ALL KNOW, who - in new idea development sessions - says 'Let me just play Devil’s Advocate for a minute…' and then proceeds to be the force for negativity that manifests to crush new concepts and potentially innovative ideas before they have even had a chance to grow.
Tom says 'This person represents a subtle yet toxic danger to your organization’s cause, greatly diminishing the chance for innovation with their negativity and naysaying.'
Get this person out of the room, immediately.
