Re: [ba-ohs-talk] IBIS question
It seems to me that some of the discussion below begins to suggest
something along the lines of Kelly's Personal Construct Theory. If one
wants to register opinions, and I've thought about this a bit, one just
gives an 'argument' window that has a slider on it, center neutral, and
degree of bias in favor or against a proposition, or as a selector between
different propositions. (01)
It then seems to me that when you do this, you might lose the ability to
state justifications. (02)
