What should you do when contrarians disrupt?

DOES this situation sound familiar? You are in a meeting, and you and your colleagues are energetically discussing how to handle an important issue or challenge. Ideas and suggestions are bouncing around so fast that the designated note-taker can barely keep up.

Then a new voice chimes in, belonging to an employee who never talks in such meetings. It is as if one of the chairs in the conference room suddenly started speaking. The group falls silent and pays close attention, clearly expecting something special.

But it is soon evident why this person usually stays silent. Their idea seems flown in from another discussion entirely. It appears to have no connection to what anyone else has been saying, let alone to the issue at hand. After a polite, awkward and brief silence, the general conversation resumes where it left off as if the quiet one had never spoken.
