I’ve written many posts and articles making the point that the political right, in most English speaking countries[^1] has been taken over by a tribalist post-truth politics in which all propositions, including the conclusions of scientific research, are assessed in terms of their consistency or otherwise with tribal prejudices and shibboleths.
Very occasionally, intellectuals affiliated with the political right (conservatives and libertarians) will seek to deny this, arguing that isolated instances are being blown out of proportion, and that the right as a whole is committed to reasoned, fact-based argument and acceptance of “inconvenient truths’ arising from the conclusions of scientific research[^2], [^3].
But, far more often their response takes the form of a tu quoque or, in the language of the schoolyard, “you’re another”. That is, they seek to argue that the left is just as tribalist and anti-science as the right. Favored examples of alleged left tribalism included any rhetoric directed at rightwing billionaires ( Murdoch, the Kochs and so on). The standard examples of alleged left anti-science are GMOs, nuclear power and anti-vaxerism, but it is also sometimes claimed that US Democrats are just as likely as Republicans to be creationists.
I’ll argue over the fold that these examples don’t work. What’s more important, though, is what the tu quoque argument says about those who deploy it, and their view of politics. The implied claim is that politics is inherently a matter of tribalism and emotion, and that there is no point in complaining about this. The only thing to do is to pick a side and stick to it. What passes for political argument is simply a matter of scoring debating points for your side and demolishing those of the others. So, anyone who uses tu quoque as a defence, rather than seeking to dissuade their own side from tribalist and anti-science rhetoric, deserves no more respect than the tribalists and science deniers themselves, who at least have the defence of ignorance.
Now let’s look at the tu quoque in a bit more detail. First, there’s the claim that the left is just as anti-science as the right. Of the three examples, anti-vaxerism can be dismissed most easily. US presentations of this argument (it’s rarely made in Oz) invariably focus on Robert F. Kennedy Jr, who is indeed an anti-science loon. But the most notable thing about RFK jr is that he happens to share his name with his famous father. He’s never held, or even stood for, elective office of any kind. By contrast, prominent Republican politicians included Michelle Bachmann and Dan Burton have pushed anti-vax rhetoric.
At one time, the generally leftish Huffington Post ran a lot of anti-vax stuff. But they came under sustained pressure from the pro-science left, and have now abandoned this almost entirely. The only recent anti-vax piece I could find came from Lawrence Solomon, a right wing Canadian climate denier (more on this later) And survey evidence suggests that anti-vaxerism, like other conspiracy theories, is more prevalent among Republicans. A PPP poll reports that 26 per cent of Republicans believe that vaccines cause autism, compared to 16 per cent of Democrats.
Next, there’s nuclear power. As we’ve discussed, policy choices regarding nuclear power raise a wide range of issues, few of which can be answered by referring to peer-reviewed scientific evidence. The right wing claim (usually implied rather than spelt out) is that the left is opposed to nuclear power because of unjustified fears about health risks and accidents. The standard straw person here, filling the role of RFK Jr in the antivax debate, is Helen Caldicott. The problems with the right wing claim are numerous
First, the left as a whole does not take any unified view on this question. Most obviously, the Obama Administration in the US has promoted nuclear power as part of an “all of the above” approach to climate change, and has received little in the way of pushback from the broader US left (compare the intensity of the campaign against Keystone XL with the handful of desultory protests against nuclear plants currently under construction)
Second, while some on the left may have opposed nuclear power for reasons that don’t stand up to scrutiny, they at least got closer to the correct answer on the broader question of whether nuclear power is a sensible solution to our energy problems. It is the political right who have proved immune to evidence on this question. No country in the world has, as yet, managed to sustain cheap and safe nuclear power over any lengthy period, and investors everywhere have abandoned the technology. Yet the belief that nuclear power is a solution to our problems, being blocked only by crazy greenies, remains a cornerstone of rightwing tribal identity.
Finally, even on the narrow question of accident risks, it’s hard to reach a conclusive answer. Nuclear meltdowns are rare but extreme events. No one can say for sure that the worst accidents we’ve seen so far (TMI,Chernobyl and Fukushima) encompass the worst that can possibly happen. These are complex engineering questions on which science doesn’t have a lot to say. Alleged experts who claimed to know for sure (notably Barry Brook in relation to Fukushima and the pre-TMI Rasmussen report on nuclear safety in the US) ended up with egg on their faces. My own judgement is that accident risks alone aren’t enough to reject nuclear power, but the cost of the safety precautions required to prevent accidents is part of the reason nuclear power is inefficient.
Evolution and creationism provide an even more interesting case. Until relatively recently, beliefs about evolution were largely uncorrelated with political affiliation. But creationism is now a Republican political issue, and beliefs are lining up accordingly, with Republicans supporting biblical literalism and Democrats mostly supporting theistic evolution[^4]
Finally, there is the question of Genetic Modification (GM) technology. This is the strongest point of the rightwing tu quoque. Greenpeace, for example, is guilty as charged of being anti-science on this issue. But Greenpeace and likeminded groups are only a minority among Greens who are, in turn, only a minority of the Left.
There are a variety of reasons for being concerned about the assertion of corporate ownership over genetic resources of which GM is (a relatively small) part, and for allowing consumers to choose whether or not to consume GM foods (regardless of whether there are objective reasons to prefer non-GM to GM, or vice versa). But outright opposition to GM based on spurious claims about health risks is definitely a minority position.
Turning to tribalism, it is silly to point to criticism of figures like Murdoch and Rinehart as tribalist. They are powerful people who use their power (derived from wealth) to advocate bad policies, and do so in an aggressive and dishonest way. The fact that they then whine about being the subject of counter-attacks, is just further evidence of their dishonesty.
Similarly, there is nothing inherently tribalist in advocating policies that would redistribute income, wealth and power away from the rich for the benefit of society as a whole, any more than in advocating free market policies that would harm some groups and benefit others. Such policies should, be advocated on the basis that they will make society as a whole better off, and not on the basis that the winners are the right kinds of people and the losers the wrong kind,
Tribalism involves attacks designed to mobilise one group against another on the basis of perceived identity. It is easy to point to a long list of groups perceived as tribal enemies by the right: environmentalists, public sector workers, unionists, gays, scientists, cultural ‘elitists’, refugees, welfare recipients (except age pensioners), ethnic and indigenous ‘lobbies’ and so on: in fact, just about any group that is seen as supporting the left or centre-left, is attacked in these terms.
By contrast, most of the groups that form the base of the political right (for example: small business, farmers, the military, self-funded retirees, mainstream churches) are treated with solicitous respect by the centre-left parties. The most notable example of a group commonly treated as a tribal enemy is that of fundamentalist Christians, and even here, there have been plenty of attempts at engagement, for example, on the idea of environmental stewardship.
To sum up, even when true, the tu quoque argument is an implicit admission of error. When it isn’t true, as in the case of the claims that the left and right are equally guilty of tribalism and anti-scientific thinking, it amounts to an intellectual coverup.
[^1]: Almost entirely in the US, Canada and Australia. To a slightly lesser extent in UK and NZ. [^2]: By contrast, this is the normal response when instances of racism or corruption are pointed out. The primary defence is that these instances are unrepresentative. A tu quoque if offered, is usually of the form “there are similar instances on the left”, but no one on that side would concede that they are unrepresentative. [^3]: Here’s an attempt, which relies on the ludicrous claim that among Congressional Republicans ” the vast majority do not reject the underlying science of global warming” (There’s also a big load of tu quoque) [^4]: Some have tried to argue that this position is just as inconsistent with science as is Young Earth Creationism. But in reality, anyone who believes both in God (in the usual senses of this term) and evolution must believe that God guided evolution, just as they must believe that God was responsible for the Big Bang and the evolution of the universe. More generally, they must believe that religion is consistent with the findings of science. Whether or not this is a logically defensible position, it isn’t anti-science.
Note to commenters: This is a repost from my blog, edited to remove some Oz-specific references. Nuclear power gets done to death there, so I’d prefer no discussion of the topic here.
