Where two alternative states are presented as the only possibilities, when in fact more possibilities exist.
Why it's wrong

Example
The motivational speaker told the crowd, 'You are either a roaring lion taking charge of your life, or you are a frightened mouse destined for failure. There is no in-between.'
