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.
So now we want to convince other people of the truth. We want to convince them that, regardless of what they may have heard in the media or from their friends, they should not believe that there is a link. How do we do that? Not through science. While it may seem that simply presenting people with the results of scientific studies should convince them, the evidence from other studies (studies into what makes people change their minds) shows that, generally, it does not. Indeed, walking people through scientific studies and presenting them with evidence has remarkably little effect on people’s views, much of the time. Consider: we live in an age in which everyone with an internet connection has access to huge amounts of scientific information, and yet exposure to such information has not led to huge upsurges in the percentage of people who believe in evolution, for instance, nor did it prevent the scare over MMR.
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.
