Keywords

💡Information Quality

Information Quality refers to the characteristics of information that make it valuable and useful for decision-making. In the context of the video, it is central to the theme as it discusses the importance of accurate, up-to-date, and comprehensive information in solving problems. The script uses the example of a student, An, who needs to find reliable information to choose a school after graduation, highlighting the consequences of misinformation.

💡Decision Making

Decision Making is the process of selecting a course of action from among multiple alternatives. The video emphasizes that decisions are heavily influenced by the quality of information available. For instance, the script mentions how having accurate information about an approaching storm can lead to appropriate preparations, thereby minimizing damage.

💡Misinformation

Misinformation is false or inaccurate information that can lead to incorrect conclusions or actions. The video script illustrates the dangers of misinformation through the story of a tragic airplane accident caused by communication errors, underscoring the critical role of accurate information exchange.

💡Key Opinion Leader (KOL)

A Key Opinion Leader, or KOL, is an individual who has significant influence over a particular audience. In the script, the concept is discussed in relation to advertising and consumer behavior, noting that while KOLs can be trusted sources, it's still important to evaluate the information they provide before making decisions.
