Interesting idea, so help me understand exactly what a threat matrix is. Also, is there any chance you are mistaken in thinking there are lots of people concerned about these types of things? Maybe there are other things that would be more important to focus on? If it is important, how many of these types of people will be convinced, as much as you, by such a threat matrix? Many of these people are likely very different than you, so maybe there is something different that will be much more effective at convincing them?
All of this type of stuff requires modern amplification of the wisdom of the crowd processes to be done most efficiently and quantitatively. It helps to be able to rigorously measure concisely and quantitatively what everyone is thinking, and fearing. And when you throw evidence, like a threat matrix out there, it helps to have a quantitative measure to find out how many people it does convert, vs some other method or evidence. Maybe a slight tweak in the threat matrix will significantly improve how powerful it is against your target audience? All this stuff is nice to be able to measure. For example, at Canonizer.com, when a new argument or tweak to such (or any demonstrable scientific proof) shows up, you can measure how many people such converts to a better camp. The arguments and evidence that converts the most targeted people are the ones you want to focus on, not just what converts you, the expert who already understands.
