It's more of a communication tool than one for exact modeling of system dynamics, but this could follow once the basic mechanics are agreed on.
For example, let's take global warming as an example. The embellished fake news narrative is that any action at all to reduce our carbon footprint will bring about complete economic collapse, and that global warming is fake news anyway and extreme weather has a completely intangible effect on the life of people living today.
Both of those are false embellished fake news narratives that build upon real concerns. It's true that we should keep the economic health of the nation in frame when we discuss measures. It's true that we might to some extent insure ourselves against natural distastes. But the fake news narrative is the embellishment of these concerns.
Is it selfish to take the attitude that humanity will deal with the consequences of its actions as they arise? That rather than expending vast amounts of capital reorganizing and regulating society to prevent disturbances before they happen we can instead accept the disturbances and deal with the consequences as necessary?
I don't personally think very highly of such a plan but neither do I think that it is reasonable to apply a blanket label of "selfish" to anyone who speaks in favor of it.
Take your global warming example, and suppose we have a magic wand to make everybody agree that it's happening, that humans were causing it, that its happening fast enough to cause massive extinctions, and that action now might still prevent this. With all of these given as universally held beliefs, it should be easy to resolve right? Well no, because in this scenario the magic wand aligned just about everything except values. Does somebody really care about the long term ecological impact of the thing more than they care about how environment austerity would impact them and their family personally? Some will, some won't, so the political debate remains standing. In fact, many of those selfish people will probably decide to stubbornly insist on a narrative that global warming isn't real, even though they know it is (thanks to the magic wand), so you'll be left wondering if your wand even worked at all.
