Exploratory.
I may have missed understood your question, but let me try to answer the best I can.
Sometimes people simply want answers and confirmations to their suspicions. Without looking at all evidence, we miss the whole. Much of our knowledge and technology today was derived from exploring "what-ifs". Humans are emotional and the unknown can frighten us, so we try to rationalize our surroundings through communication and it is communication that promotes understanding.
Passionetpain wanted to share experiences that could be discussed; sharing a need for communication and understanding.
