interactional reasoning: cognitive or myside bias?

leave a comment »

In the previous post on this topic, I wrote of surprise as a motivator for questioning what we think we know about our world, a shaking of complacency. In fact we need to pay attention to the unexpected, because of its greater potential for harm (or benefit) than the expected. It follows that expecting the unexpected, or at least being on guard for it, is a reasonable approach. Something which disconfirms our expectations, can teach us a lot – it might be the ugly fact that undermines a beautiful theory. So, it’s in our interest to watch out for, and even seek out, information that undermines our current knowledge – though it might be pointed out that it’s rarely the person who puts forward a theory who discovers the inconvenient data that undermines it. The philosopher Karl Popper promoted ‘falsificationism’ as a way of testing and tightening our knowledge, and it’s interesting that the very title of his influential work Conjectures and refutations speaks to an interactive approach towards reasoning and evaluating ideas. 

In The enigma of reason, Mercier and Sperber argue that confirmation bias can best be explained by the fact that, while most of our initial thinking about a topic is of the heuristic, fast-and-frugal kind, we then spend a great deal more time, when asked about our reasoning re a particular decision, developing post-hoc justifications. Psychological research has borne this out. The authors suggest that this is more a defence of the self, and of our reputation. They suggest that it’s more of a myside bias than a confirmation bias. Here’s an interesting example of the effect:

Deanna Kuhn, a pioneering scholar of argumentation and cognition, asked participants to take a stand on various social issues – unemployment, school failure and recidivism. Once the participants had given their opinion, they were asked to justify it. Nearly all participants obliged, readily producing reasons to support their point of view. But when they were asked to produce counterarguments to their own view, only 14 percent were consistently able to do so, most drawing a blank instead.

Mercier & Sperber, The enigma of reason, pp213-4

The authors give a number of other examples of research confirming this tendency, including one in which the participants were divided into two groups, one with high political knowledge and another with limited knowledge. The low-knowledge group were able to provide twice as many arguments for their view of an issue as arguments against, but the high-knowledge performed even more poorly, being unable to provide any arguments against. ‘Greater political knowledge only amplified their confirmation bias’. Again, the reason for this appears to be reputational. The more justifications you can find for your views and decisions, the more your reputation is enhanced, at least in your own mind. There seems no obvious benefit in finding arguments against yourself.

All of this seems very negative, and even disturbing. And it’s a problem that’s been known about for centuries. The authors quote a great passage from Francis Bacon’s Novum Organum:

The human understanding when it has once adopted an opinion… draws all things else to support and agree with it. And though there be a greater number and weight of instances to be found on the other side, yet these it either neglects and despises, or else by some distinction sets aside and rejects, in order that by this great and pernicious predetermination the authority of its former conclusions may remain inviolate.

Yet it isn’t all bad, as we shall see in future posts…

ten negatory claims about same-sex marriage

with one comment

bd5496a07bfad40db17c779335cfafb8

percentages of those favouring same-sex marriage (in the US) over twenty-odd years – one of the fastest changes in public opinion in human history

What are the arguments against same-sex marriage? That’s a question I’m asking myself as I hear that conservatives want public money to run a campaign against it if Australia holds a plebiscite – which I’m not particularly in favour of, but at least it makes me reconsider the ‘no’ arguments. Presumably they’d be along the same lines as those of the TFP (tradition, family, property) organisation of the USA, but Australia as a nation is less religiously fixated than the USA, so the weak arguments found on the TFP website would seem even weaker to people over here. But let’s run through their 10 arguments just for fun. You can read them in full on the website if you’ve nothing better to do.

1. It is not marriage.

The claim here is that you can’t just redefine marriage to suit changing situations. ‘Marriage has always been x’, (x usually being identified as a ‘covenant between a man, a woman and god’ or some such thing). The response is, we can and always have done. Marriage is a human invention, and like all inventions we can modify it to suit our needs. A table is a human invention, and it can be a chess table, a bedside table, a coffee table, a dining table or a conference table, and none of these uses threatens the meaning of the word ‘table’. Marriage is ours to define and use as we wish, and historically we’ve done just that, with polygynous marriages, which have been commonplace, polyandrous marriages (much rarer) and other more or less formal arrangements, such as handfasting and morganatic and common-law marriages. Of course, marriage has rarely been recognised between individuals of the same sex, though same-sex unions, some of them highly ritualised and contractualised, have had a long history. But the reason for this is obvious – throughout history, homosexuals have been tortured and executed for their feelings and practices. The history of exclusive male-female marriage coincides with the history of homosexual persecution. The two histories are not unrelated, they’re completely entwined.

2. It violates natural law.

WTF is natural law, you might ask. A TFP fiction apparently. Their website says: Being rooted in human nature, it [natural law] is universal and immutable. But human nature is neither of these things. It’s diverse and evolving, socially as well as genetically. Marriage and child-rearing arrangements vary massively around the globe, with varying results, but it seems clear from voluminous research that children benefit most from close bonding with one or two significant others, together with a wider circle of potential carers and mentors. It’s notable that when this organisation lays down the ‘law’ on matters of marriage, sexuality and families it cites no scientific research of any kind – its only quotes are from the Bible.

3. It always denies children either a father and a mother.

Leaving aside the fact that there are often no children involved, this argument relies on the assumption that a father and a mother are indispensable to the proper rearing of children. Research reported on in Science Daily found that ‘children raised by two same-gender parents do as well on average as children raised by two different-gender parents. This is obviously inconsistent with the widespread claim that children must be raised by a mother and a father to do well’.  Melvin Konner in his 2015 book Women after all puts it this way: ‘One of the most impressive discoveries of the last decade in child development research is that when babies of either sex are adopted by lesbian or gay couples – and this has been studied very extensively and carefully – the main way the resulting children differ from controls raised with a father and mother is that they turn out to be less homophobic.’ Of course, this is exactly what organisations like TFP are afraid of, as promotion of homophobia is what they’re all about.

4. It Validates and Promotes the Homosexual Lifestyle

And that’s precisely what it aims to do. Of course TFP argues, or rather states without argument, that this would ‘weaken public morality’. Humanists would argue precisely the opposite, that such validation is long overdue, and would strengthen a morality based on the recognition of the fundamental humanity and value of diverse individuals.

5. It Turns a Moral Wrong into a Civil Right

In its discussion of this reason to oppose same-sex marriage, TFP again refers to its bogus ‘natural law’. Same-sex marriage (always in inverted commas on its website ) is opposed to nature, according to TFP. Again this is stated rather than argued, but as I’ve often pointed out, bonobos, our closest living relatives, engage in homosexual acts on a regular basis. Of course, they don’t marry, because marriage isn’t natural, it’s a human construction, and mostly a quite usefiul one, though not necessary for child-rearing, or for permanent monogamous relationships. Further to this, researchers have observed homosexual acts in between 500 and 1500 non-human species, so it seems to be natural enough.

6. It Does Not Create a Family but a Naturally Sterile Union

Again TFP makes ad nauseum use of the word ‘nature’ to give credit to its views. But the fact that same-sex couples can’t have offspring without outside help isn’t a reason to debar them from a union that serves multiple purposes. Moreover, it’s quite reasonable for homosexual males or females to feel that they would make good parents, and to yearn to be parents, and there is no reason why this should yearning should be opposed, if the opportunity to parent a child arises. Adopted children are often brought up in loving and happy environments, and succeed accordingly.

7. It Defeats the State’s Purpose of Benefiting Marriage. 

It’s hardly for the TFP or any other organisation to tell us what the State’s purpose is regarding marriage. Most advanced states provide benefits for children, regardless of the marital status of the mother. This is very important, considering the large number of single-parent (mostly female) families we have today. The state also doesn’t distinguish between marriage and de facto relationships when it dispenses benefits. The TFP is obviously out of date on this one.

8. It Imposes Its Acceptance on All Society

States are legalising same-sex marriage around the western world under public pressure. Here in Australia, where same-sex marriage hasn’t yet been legalised, polls have indicated that same-sex marriage is clearly acceptable to the majority. Where it is up to courts to decide, as occurred recently in the USA, the process is too complex to cover here, but it’s clear that the public’s attitude to same-sex marriage in every advanced or developed nation has undergone a seismic shift in a relatively short period – the last ten years or so.

9. It Is the Cutting Edge of the Sexual Revolution

Vive la révolution. Of course, TFP presents the slippery slope argument – paedophilia, bestiality and the like – so hurtful and offensive to the LGBT community. Again, there’s never any presentation of evidence or research, every proposition is presented as self-evident. It’s a profoundly anti-intellectual document.

10. It Offends God

This is, of course, presented as the main argument. Biblical quotes are given, including one in which their god’s mass immolation of ‘sodomites’ is celebrated. I don’t really see much point in questioning the supposedly offended feelings of a supposedly all-perfect, all-powerful invisible undetectable being. It’s all a fairly nasty fantasy.

There’s nothing more to say, and as an intellectual exercise this was probably a waste of time, as people who believe the above guff aren’t listening much. Any critical responses to their 10 propositions on the TFP website will be promptly deleted. There’s definitely no fun to be had with these guys. Their absolute certainty, and their inability and unwillingness to argue cogently or to examine evidence is a very disturbing sign, and a clear indication that they’re fuelled entirely by emotion. A passionate fear of change and difference. It all tends to reinforce the arguments against holding a plebiscite, in which, in Australia, people of this sort would actually be funded to give voice to their certainties with all the indignation of righteousness. They would be ruthless about their targets, and being patriarchal  – because preserving extreme patriarchy is what this is all about at base – they would be violent in their language and tactics. The best way to muzzle them would be to resolve this in parliament as soon as possible.
