Ask HN: Is there a way to quantify opinions into a tangible tree/graph?

Take any given topic, say political for example.

Say the president does or says something.

Is there a way to quantify everyone's opinion about this into a tangible set of statements that you can agree or disagree with?

    In addition to ACH (mentioned by tboyd47), there is argument mapping.

    There are many ways to do it.

    You could load documents containing facts, opinions or other information into a database and then add another "table" that links one thing to another so we can say that "opinion B is a response to opinion A" or that any sort of relationship exists between them.

    I think this even more interesting when we apply it to a set of documents that have business, engineering or science value.

    Yes! There is a great way to do this called ACH (Analysis of Competing Hypothesis). It's a wonderful way to clarify your thoughts about a complex issue. It is used within the CIA.
