Effective Epistemic and Persuasive Techniques are Not the Same
Freethinkers who wish to communicate effectively with the public are confronted by a significant problem: the difference between the epistemic and the persuasive. Put simply, the problem is this: the methods which are effective when determining what is true (our epistemic tools) are not the same methods which are effective at convincing others that something is true (our persuasive tools).
An example: if we want to determine whether there is a link between MMR vaccines and autism (there is not), we have to engage in scientific studies, clinical trials, longitudinal analyses of people who have had the jab, etc. This is an epistemic process: our aim is to discover the truth, to determine if there is, in fact, a link between the MMR vaccine and autism. The processes we use to do this generally come under the heading of “science”: experimental tests in controlled settings. They reveal that there is not a link between the MMR vaccine and autism.
This is, on reflection, unsurprising: there is no reason why the best methods for discovering the truth should necessarily be the best methods for persuading people that something is true. The techniques we have developed – painstakingly, over centuries – for determining the truth, while they are extensions of natural processes of thought, are not themselves easy for human beings to perform. We are notoriously intellectually fickle, beset by all sorts of biases and prejudices, and even the best scientists are sometimes unable to follow the evidence where it leads. Why should we expect people with no genuine scientific training to be particularly receptive to highly technical forms of evidence which are generated by processes they don’t understand?
And yet there is a tendency among freethought activists to assume or assert that, if you just present people with the evidence, the evidence should “speak for itself”. Good arguments and good evidence are strong enough to stand alone, many think. Not so. Evidence never speaks for itself, and good arguments do not stand alone. The best arguments – if they are to be convincing – must always be supplemented with an intelligent respect for the ways in which human beings process information, the way they assess the trustworthiness of a messenger, the way emotions play a role in our thinking. To ignore what we know about persuasion, and to equate persuasive with epistemic pursuits, is to misunderstand the purpose of persuasive communication, and to dull the potential of our persuasive efforts.
Thinking carefully about how we communicate the truth – once we have discovered it – and recognizing that the techniques we use to communicate the truth aren’t necessarily the same as those we use to discover it, does not imply that we do not care about the truth. On the contrary: it demonstrates we care enough about the truth that we are willing to learn how best to communicate it. That’s what these posts are about.
