What you thought was one concept is two nested concepts

• We were talking about a concept, calling it A.
• But it doesn't come across well.
• After digging into why, I discovered that there are two concepts called A
  • Hereinafter referred to as A1 and A2.
• These two are in implication in event space.
  • in other words
    • A1 then A2
    • A2 but not necessarily A1
• If you do not pay attention to this "A2 but not A1" event, or if it is very rare, A1 and A2 appear to be the same thing
  • As a result, one word, A, calls them both
  • This is a state where the boundary of the concept of A is blurred as shown in the lower left figure.
  • Humans can manipulate symbols without realizing that the boundaries are blurred concepts.
    • Often overlooked unless one is trained to clarify boundaries.

relevance - Blurred Boundaries - Unclear dichotomy - Unclear concept - The usefulness of defining the boundaries of a concept - This is about whether it is useful to clarify Conceptual Boundaries or not, depending on the situation. - Boundary blurring - This is a lot about organization. - In Relation Question, you're asking about the relationship between two concepts, but there are cases where two concepts are classified with in the first place. - Cognitive Resolution - One-dimensional version of cognitive resolution - In Resolution Stage, you had the lowest resolution state as dichotomy, but there's even more "identical." - What you thought was one concept is two concepts - A set that was assumed to be equal
