The ability to persuade other people is important for human rights in at least two different ways:
- How do we achieve respect for human rights? Since a lot of human rights violations are caused by ideas and opinions – for example by harmful moral judgments or political ideologies – respect for human rights depends at least in part on our ability to change minds, other people’s as well as our own.
- Why do we need human rights? Certain human rights in particular, such as the right to free speech, are justified by our need to persuade others. We want to express ourselves and we express ourselves for different reasons: to communicate our identity, to signal what we think about something, but most importantly to persuade others of the goodness of our opinions, compared to their opinions. That’s a universal human need. Ideally, we also believe that expressing our opinions improves those opinions. We prepare our opinions in advance of expressing them, and – knowing that we will be criticized for those opinions by other agents freely expressing themselves – we try our best to prepare our opinions for this criticism. We consider possible counterarguments in advance and how to reply to them. This brings with it the possibility that we refine our opinions or even replace them with better ones, based on our inner reasoning in preparation of our expression. Free speech – our own free speech and that of our critics – helps us improve our opinions. Persuasion – both of others and of ourselves – is therefore an important reason why we need human rights. (This is the theory behind the notion of the marketplace of ideas).
The problem is that people don’t seem to be very good at persuading each other or themselves. The description of communication that I’ve given here is highly idealized. If we can’t dramatically improve our ability to persuade, then we’ll have a hard time fighting for rights because we’ll lose weapons as well as reasons necessary for this fight. There are other non-communicative means to increase the levels of respect for human rights (reciprocity, self-interest, the law etc.), and the need to improve our opinions and to persuade isn’t the only possible justification for human rights (other justification are offered here). But in such an important fight a restricted arsenal or rationale is a net negative. So it’s worth the effort to try and remove some of the things that make it hard to persuade.
So what are we up against? Apart from the obvious and uninteresting fact that some people are immune to persuasion – good luck talking to the Taliban – there are other and perhaps even more damaging causes of a lack of persuasion: confirmation bias, the importance of emotions rather than reasoning or argumentation as a basis of our beliefs, polarization, and a whole set of other psychological biases (e.g. the belief that beautiful people make better sounding arguments).
What to do about all this? We should avoid the obvious conclusion that humans are merely bias machines governed by unconscious reflexes, responses to stimuli, emotions and prejudices formed through ages of human evolution. Or that rational argument based on facts and sound reasoning never plays any role. Many but probably not all our opinions and decisions are biased by prejudice and emotive reactions created by a mind shaped by evolution. There’s certainly no hope of radically removing those parts of our minds that work that way, but we can hope to reduce their effect. If we are conscious of our confirmation bas, for instance, then we can try to counteract it by actively seeking out disconfirming information or by making an effort to read people from the opposing side. Rational persuasion can and does occur, and we can make it occur more often than it does today. For example, here and here are two examples of cognitive scientists pushing back against the current trend in their profession. They show how strong arguments can indeed persuade people and how group reasoning in particular is helpful.
