Thinking about the Science of Psychology
31st January 2011
I’d like to direct you to perspective article that is only tangentially about persuasion, but more about how to think about research whether related to persuasion or any other human behavior. Gregory Miller offers a strong critical and often negative look at the New New Thing in psychology, neuroimaging, and considers its implications for the scientific study of human thought and action. For me, Miller thinks the way a scientist should and in so doing demonstrates the benefits of science for both basic research, but also for applied practice. The first sentence of his abstract establishes everything.
We systematically mistreat psychological phenomena, both logically and clinically. This article explores three contentions: that the dominant discourse in modern cognitive, affective, and clinical neuroscience assumes that we know how psychology/biology causation works when we do not; that there are serious intellectual, clinical, and policy costs to pretending we do know; and that crucial scientific and clinical progress will be stymied as long as we frame psychology, biology, and their relationship in currently dominant ways.
Miller focuses upon a specific problem, the psychology/biology connection, but please realize that his observations and arguments hold for anyone who tries to understand any field of relationships, how things go together. How do you know what you know?
Miller asserts, and I agree, that current neuroimaging work typically assumes well established models of psychology/biology connection when a more careful and thoughtful reading of that literature would lead to an opposite assessment: We know very little about those connections. Miller then notes the harms of this scientific cheerleading: We will fail both theory and practice.
Now, let’s pivot from neuroimaging to persuasion on this Rule: You Cannot Persuade a Falling Apple. If you have science, which, for example some neuroimagers believe, then you have a Falling Apple. It is self evident, as in the instance of gravity’s existence proven when you fall off a log. Thus, there is no need to persuade Falling Apples, yet if you read much neuroimaging research there is the unmistakable whiff of persuasion in the air. Why persuade a Falling Apple?
The generalization of this thinking immediately engulfs all those scientists who use their Falling Apples to make the world a better place whether through neuro-informed interventions for clinical mental health improvement or reducing the waistlines of overweight Americans. This Blog reeks with those bad examples of failed science and failed persuasion usually brought on from the combination of two Rules, Falling Apples and All Bad Science Is Persuasive.
Miller’s perspective is technical and even well educated readers in other fields will doubtless find it tough going. Simply because you have a psychology of yourself that you’ve lived with your whole life does not mean you have much understanding of that psychology whether of just yourself or of human nature. In other words, your own human nature gets in the way of understanding yourself and others. To read an owners manual on yourself can be more than disconcerting.
Persuasion is a powerful tool for change when you know what you’re doing. But, you’ve got to know what you know first.
