Fortunately, there are certain tactics that you can use to diffuse the problem and prevent those troublemakers from throwing a monkey wrench into everything you’re trying to do.
Here are 10 ways to handle ideation bullies.
1. CHOOSE YOUR BRAINSTORMERS
One option is to simply not invite somebody who is known to be a troublemaker if you predict that that person is going to tank the effort to bring people together and generate ideas.
Of course, that individual may actually have good ideas to contribute, it's just that they have a habit of “over-contributing. If their contributions are important, you can give them another way to participate, such as asking them to send you a list of their ideas.
But there can be downsides to this as your primary approach. If that person is politically very important, then excluding them may not be wise.
And lastly, sometimes you don’t know in advance who will show up as an “ideation bully.”
Someone who is otherwise quite reasonable and collaborative may get “triggered” by a given topic and transform into a problem.
