Final answer:
The statement is false; monochromic societies are actually characterized by a linear, scheduled approach to time, while polychronic societies are more cyclical and unscheduled.
Step-by-step explanation:
The statement that societies based on monochromic time tend to be cyclical and unscheduled is false. Monochromic time societies are characterized by a linear and scheduled approach to time management, where people tend to do one thing at a time and adhere to prearranged plans. Cyclical and unscheduled time perceptions are more often associated with polychronic societies, where time is seen as constant and fluid, allowing for multitasking and a more flexible approach to scheduling.
