Perhaps the mapping method could benefit from some refinement.
You, Kaj, acknowledge that some of these posts may be controversial. This is a good start, but from my experience there is a portion of the population that finds even discussion of personal information unpleasant. The beginning of a fresh relationship is about creating a safe conversational space. Assessing the listener’s reaction to your communication. If you truly mean to map future conversations, then a guided walk with specific branch points based on listener attitudes may be helpful.
However, I worry that you may be taking some of the “interesting” out of the conversation. Perhaps brainstorming on the different the type of people you are likely to meet will allow you to generate topics you wish to learn more about. I would suspect that you are better able to converse with those whom you have much in common with. The graph depicts conversations that the majority of the population have little interest in.
In fact, I would be more interested in exploring these topics in a hypertext document. I just tried to click on entries (they are underlined as if linked) and was disappointed. Especially enticing is the personal background—climate change—job connection and your unusual set of connections to world building.
Another thought: isn’t SIAI engaged in world building?
I often (~monthly) believe that my name is being called when further investigation suggests otherwise. I believe it is a result of a similar sibilant sound and my upbringing. My stepfather insisted that if he shouted my name I had to come running, even if I was out of earshot blocks away. Thus I was “nurtured” towards false positives.
This audio hallucination always fools me, but visual hallucinations never do.
At approximately the same rate (monthly), I imagine I see a cloaked figure. This is more an optical illusion in my peripheral vision, which I quickly recognize. Occasional Melatonin or Vitamin D greatly reduce the occurrence of this optical misidentification.
