It is rare for people to be asked the question which puts them squarely in front of themselves. (Arthur Miller, The Crucible)1
Why do people hold the political views that they do? Even if you have only a passing interest in politics, it is likely that you have thought about this question. If you are a Labour supporter, you might regard Conservatives as greedy. If you are a Brexiter, you may consider the views of Remainers to be driven by financial interest in EU membership. If you are a Remainer, you might think Brexiters are deluded. It is possible that you regard the foundations of your own views more charitably; many consider themselves guided by concern for the less fortunate or by the need to achieve national renewal.
Debates such as these will be familiar to anyone who is interested in politics. Though such discussions are diverse, they have one thing in common; they concern self-interest. There have always been disputes such as this in politics, yet in recent years they have intensified and we increasingly misunderstand the motives of others. It is this crisis which moved me to write this book. Why did Brexiters and Remainers vote as they did? What moves Conservative and Labour supporters as they head to polling booths? Who do different perspectives benefit?
My answer is almost as brief as the question. Most people gain something from their views. The reasons why this is the case are simple. We are evolved animals and, consistent with premises of a range of academic fields, tend to act in our self-interest.2 Altruism may exist, scholars recognizing its evolutionary basis,3 yet self-interest is an unescapable part of the human condition; it has characterized previous societies and will distinguish future ones. Contrary to common wisdom, interests are at least as important as ideas and structure politics in crucial ways. When this insight is applied to contemporary politics, one is confronted with puzzles. Why do richer citizens vote for parties which pledge to reduce inequality? Why would people who live in areas dependent on European funding detest the EU? Why do the well-to-do care passionately about Syrian asylum seekers?
The link between the interests of such citizens and these issues may often be indirect, yet associations become clearer if three influences are understood. Firstly, humans sometimes express interests in non-material terms. Scholars have long known that humans do not merely respond to economic incentives; we also react to psychological stimuli.4 Left-wing and liberal worldviews, which mobilize adherents against injustice, are associated with concerns such as care and fairness. Yet non-material values can be directly related to self-interest. In our globalized world, change disadvantages immobile populations; worldviews which activate values such as patriotism, as a means of controlling changes harmful to these citizens, are thus successful. Such goals are associated with national populism. Movements such as UKIP and the Brexit Party have emerged across developed countries in recent years and are popular because they arouse defensive emotions, associated with the non-material interests of supporters.
A second consideration is that human reasoning is limited. In recent years, scholars have recognized the imperfect evolution of the brain; our minds developed to meet challenges of primitive societies, not those of a complex global economy. We are also prone to overestimate our knowledge, an evolutionary phenomenon, associated with the need to have confidence in decisions, which means that we are unaware of the degree to which our preferences benefit ourselves.5 This is sometimes the case with left-wing and liberal positions. Not only are these worldviews adopted on the basis of individual experience, meaning they subliminally reflect personal concerns, but limited resources result in altruistic elements of these perspectives losing ground to less magnanimous parts.
A third qualification is that worldviews have separate constituent parts, reflecting historical development. Though most elements may be consistent with the interests of supporters, there may be aspects which lie in tension. Because of the way in which the latter parts have become embedded in the worldviews, normally over decades, they cannot be simply discarded. Individual beliefs therefore endure, accepted by supporters because they are parts of perspectives which broadly suit their interests.6 Left-wing and national-populist movements provide examples. In the case of the left, there is long-standing focus on Israel, related to the anti-colonial history of the movement. It can be difficult to understand the attention which middle-class students lavish on the cause, yet this is a core belief of a movement which supports the economic aspirations of this group. The national-populist preoccupation with the EU has similar foundations. Though parts of Brexit threaten the interests of lower-class national populists, an economic downturn being one example, anti-Europeanism is a key element of a worldview which promises to preserve local conditions; this is in the interests of such citizens.
Why understanding self-interest is crucial
Serious discussion of self-interest is surprisingly rare. Though we ascribe this motive to opponents, we seldom reflect on our own self-interest, preferring to emphasize altruistic parts of our politics. Despite the importance of altruism, self-interest is so crucial a part of our nature that it cannot be ignored. Useful comparison may be made with sexuality, another integral part of the human character. Attempts to ignore or suppress sexuality are counterproductive; sad consequences of the repression of homosexuality or religiously imposed chastity show this. Most today recognize the need of humans to find outlets for natural urges, provided the rights of others are not violated. Awareness of self-interest is equivalent. Because of the impossibility of repressing self-interest, attempts to do so often cause frustration and chauvinism.
When one is aware of self-interest and exercises it in a way which respects the rights of others, healthy self-fulfilment encourages humility and moderation. Awareness of self-interest makes us more tolerant. People have always tended to misunderstand the motives of opponents, yet in recent years this has worsened; opponents are routinely depicted as selfish or treacherous. This is associated with the echo chambers of social media and moves away from political moderation.7 Though there are several ways in which the motives of opponents can be better understood, appreciation of self-interest is one of the most promising. Awareness of oneâs own self-interest fosters reflectiveness. Self-interest is part of the human condition and present in all worldviews; when this is understood, positions tend to be advanced less aggressively. Appreciation of the self-interest of others is similar. If one realizes that opponents are not monsters, but humans with legitimate needs, it becomes easier to see humanity in adversaries.
Awareness of self-interest would also help move politics in a more liberal-democratic direction. For centuries, theories of liberal democracy have been based on the idea that interests of citizens are distinct yet legitimate. A liberal-democratic public sphere, in which different groups deliberate grievances to advance the common good,8 attempts to resolve these differences. Authoritarians reject such methods. As Hannah Arendt and Karl Popper argued in the post-war years,9 the authoritarian sees no humanity in opponents, regarding their desires as antithetical to the common good.
Despite the importance of deliberation, there has been pressure on the institutions which uphold this. In liberal democracies, parliaments and courts follow procedures which facilitate considered debate. Institutions such as presses and ombudsmen mediate citizen engagement in a related manner, structuring participation in a way which reinforces liberal-democratic standards. Such institutions are threatened by demands for more direct engagement in politics, reflecting factors such as distrust of politicians and the rise of social media. Even if there is need for reform of our institutions, radical articulation of these demands is concerning; liberal democracy has more successes than failures and alternatives have poor records.10 Defence of liberal democracy is a wide project, involving multiple fronts, yet awareness of self-interest is crucial; it validates institutions which promote deliberation.
Recognition of different interests also allows for m...
