Final answer:
It is true that users of an information system should avoid informal information like rumors and unconfirmed reports. Verified facts and data are essential for accurate decision-making. Theories do not automatically become laws over time; scientific laws are established through observation and experimentation.
Step-by-step explanation:
When solving problems, the users of an information system should avoid using informal information, such as rumors, unconfirmed reports, and stories, because such information is not reliable and may lead to inaccurate or flawed decisions. This statement is true. Informal information often lacks the necessary verification and substantiation required for making informed decisions. In contrast, reliable information is comprised of specific facts, statistics, and examples that are proven to be correct and accurate.
For instance, in the context of an information system, decision-makers require verified data to create accurate models or formulate effective solutions. An example where the scientific method is not employed properly could be historical instances before the rigorous process of the scientific method was developed. Nowadays, relying on verified facts and data is considered the normal functioning of the scientific method. In a similar vein, it's a common misconception that when a theory has been known for a long time, it becomes a law; however, this is false. A law in science is a concise description of natural processes that have been repeatedly confirmed through observation and experimentation, not merely a theory that has existed for a long period.
