This question probes understanding of how default settings influence behavior as mentioned in the text, within a practical, real-world setting. The core challenge is identifying the most effective way to set initial habits based on the understanding that people tend to stick with defaults. **Core Concepts:** * **Default Settings:** The text states, 'most people stick with default settings'. This indicates that initial settings are often the ones people will maintain. * **Behavioral Adoption:** The question addresses the challenge of getting employees to adopt specific work habits. * **Clarity and Ease:** Implicit in setting effective defaults is ensuring clarity and ease of adoption. **Option Analysis:** * **A:** A complex manual will likely be difficult to navigate and therefore not an effective default option, as people are unlikely to engage with complicated directions. Thus, it is incorrect. * **B:** This option directly utilizes the concept of default settings. By establishing clear and easy to follow initial guidelines, it promotes the adoption of desired practices from the start, because people are more likely to stick with a default when it’s easy to understand and follow. Hence correct. * **C:** This approach ignores the importance of default settings and may lead to inconsistent and undesirable work habits. Hence, incorrect. * **D:** Learning through trial and error without established initial practices provides no strong default and therefore inconsistent work habits may occur. Hence, incorrect. **Correct Answer:** B. Clear, concise, and easy to follow guidelines will be the most effective default setting. Employees tend to stick with what is initially presented, therefore, making sure the initial practice is easy to follow, helps to achieve desired work habits. **Key takeaway:** The question tests understanding that individuals tend to maintain initial settings. Setting clear, easy defaults is more effective than overly complex manuals or unstructured learning approaches.
