Answer:
Writing a plan a priori leads people to distort what they find because they’ve already committed to an answer. For example, Mr. Biden kept attacking Mr. Trump because “he didn’t have a plan” and blamed him for all the deaths from Covid-19. It was novo-virus that nobody knew anything about and no plan based on ignorance would have saved a single life. Now he has cost a large number of people jobs because he has a plan to get rid of fossil fuels, There is no technology with solar and wind that will produce enough energy and Biden’s plan also gets rid of nuclear. They have plans to fix the police, the schools, the national debt, etc, all based on wishful thinking and ignorance of problems unseen.
