Politicians use statistics to persuade us that they understand society's problems and that they deserve our support. The media use statistics to make their reporting more dramatic, more convincing, more compelling. Corporations use statistics to promote and improve their products. Researchers use statistics to document their findings and support their conclusions. Those with whom we agree use statistics to reassure us that we're on the right side, while our opponents use statistics to try and convince us that we are wrong.
Statistics are one of the standard types of evidence used by people in our society.
It is not possible simply to ignore statistics, to pretend they don't exist. It would be nice to have a checklist, a set of items we could consider in evaluating any statistic. The list might detail potential problems with definitions, measurements, sampling, mutation, and so on. These are, in fact, common sorts of flaws found in many statistics, but they should not be considered a formal, complete checklist. The goal is not to memorize a list, but to develop a thoughtful approach.
