 What concept does this scenario illustrate? Answer：✅ B) 

The Principle of Least Effort  is a behavioral and cognitive concept that applies across multiple industries, for example User Experience (UX) & Digital Product Design.

Core Idea: Users will always take the simplest path to complete a task. If an app or website feels complicated, users abandon it.

Example:

  • A mobile payment app that requires too many steps will lose users to a competitor with a simpler one-click payment process.

  • Amazon’s “Buy Now” button is a direct application of this principle.

Industry Application:

  • Mobile app design

  • E-commerce checkout optimization

  • Website navigation design

Why it matters: Minimizing user effort improves conversion rates and customer satisfaction.

The Principle of Least Effort is universal but especially influential in:

  • Information search (Google, library systems)

  • UX design (simplifying digital interactions)

  • Marketing (reducing customer decision fatigue)

For modern businesses, this principle is crucial when designing customer experiences, digital products, and information systems, because the easier you make something, the more likely people will use it.
