In this short monologue, the speaker explains how many hotel and flight booking websites place a short countdown timer (often around three minutes) on the final checkout step where users enter personal details. The timer is deliberately set to create a sense of urgency, prompting users to complete the booking within the allotted time. The speaker links this design choice to Parkinson's Law—a psychological principle stating that people tend to expand the amount of work to fill the time available to complete it. By limiting the time, the digital product leverages this tendency, ensuring users finish the process quickly, which in practice leads to a high completion rate within the timer window.
