Thurstone's law of comparative judgment

Thurstone's law of comparative judgment is a psychological theory that explains how we evaluate items by comparing them rather than by assessing them in isolation. In the context of general knowledge, it suggests that people form their judgments about a topic or item based on their relative position compared to others they know. For instance, when deciding who is more knowledgeable about science, you compare individuals' expertise directly against each other, rather than measuring their knowledge with a standard scale. This helps to create a clearer understanding of their abilities through a process of comparison.
