Final answer:
The false statement is that divergent thinkers are unable to manage their time as effectively as convergent thinkers. Creative thinking does not inhibit one's time management skills, and brain functions are not strictly lateralized to being 'left-brained' or 'right-brained'.
Step-by-step explanation:
The statement that is false among the options provided is: Divergent thinkers are unable to manage their time as effectively as convergent thinkers. Divergent thinking relates to the capacity of forming creative and unique solutions, and there is no evidence to suggest that divergent thinkers are inherently poorer at time management than convergent thinkers.
On the contrary, people who engage in divergent thinking may also excel at planning and management, as creativity does not exclude organizational skills. Moreover, the notion of left-brain or right-brain dominance as absolute is a myth; while certain functions may be lateralized, most cognitive functions are distributed across the cerebral hemispheres.
