The argument is that the extroverts, who like to speak first and think second, will drown out the introverts, who like to think carefully before contributing.  Today I was running a creative thinking session for a major pharmaceutical company and I decided to try this.

First I read out the definitions of extrovert and introvert as given on Wikipedia.  I then asked people to self-select into which group they fitted.  It is important to stress at this stage that there is no judgement that one group is any way better than the other – they are just different in their approaches.  Happily about half of the people fell into each group.

We then did some advanced brainstorming using SCAMPER and ‘What if….?’ methods.  It worked well.  The extrovert group were lively and active with plenty of strong personalities and good ideas.  The introvert group was a little quieter but came up with ideas that were at least as good and possibly more radical than the extroverts.  In the analysis and feedback session the introverts said that they preferred the arrangement because they were not dominated by noisy extroverts.  So it was an interesting experiment that seemed to work.
