To answer this question, we need to understand the concept of "Wisdom of the crowds" and its application to Web 2.0.
Option A) Collective knowledge from many is of greater value than that of a single expert - This option is correct. The "Wisdom of the crowds" refers to the idea that the collective intelligence and opinions of a large group of individuals can be more accurate and valuable than the knowledge of a single expert. This concept suggests that when a diverse group of people independently share their opinions or make predictions, the average of their responses tends to be more accurate and reliable than an individual's opinion.
Option B) An expert opinion always outweighs that from a group - This option is incorrect. The "Wisdom of the crowds" concept implies that the collective knowledge and opinions of a group can be more valuable than that of a single expert, contradicting this option.
Option C) Experts can seek opinions from others to increase their wisdom - This option is partially correct. While it is true that experts can seek opinions from others to gain additional insights and perspectives, the core idea of the "Wisdom of the crowds" is that the collective knowledge and opinions of many people are inherently valuable, regardless of whether experts seek them or not.
Option D) Diverse collections of independently-deciding individuals require an expert to resolve conflicts - This option is incorrect. The "Wisdom of the crowds" does not necessarily require an expert to resolve conflicts. Instead, it suggests that the collective intelligence of a diverse group can often lead to accurate results without the need for an expert's intervention.
Therefore, the correct answer is A) Collective knowledge from many is of greater value than that of a single expert. This option aligns with the concept of the "Wisdom of the crowds" and its application to Web 2.0.
