Author thinks they are the lone person stuck in the middle between two tribes, but actually they are part of a third tribe that fallaciously believes that it is possible to write better policy, if only we took the time to study reality more and listen to more people and apply more reason etc. In short, Author distinguishes between the two established tribes (in which people make a very limited emotional engagement with the issues) and their tribe (in which people make a stronger emotional engagement). This is a fallacy because:
* It is not reasonable to expect most people to make strong emotional investments into voting choices that have little direct effect on their lives, and indeed we have a representative democracy rather than a direct democracy to recognize that reality
* Reality is far, far more complicated than can be summarized in journalism or articles; many researchers spend their entire careers attempting to learn deeply about *one* area, let alone many areas; much pertinent information is non-public. Policies that are effective in one community are completely counter-productive in another. Believing that you are The Exception and that you Know The Right Way To Run The Country because you "do your research" is the height of hubris.
People will seek out good leadership. People will switch leaders when their current leadership fails to make them happy. Good leaders defer to experts, each in their own domain, who may make imperfect decisions and other mistakes but nonetheless make well-intentioned efforts to improve over time and pass on their knowledge so that future generations can learn from their mistakes. All else is natural variance due to human imperfection.
