Those findings apply to a single generation, yet they tug at the edges of evolutionary theory, in which species change slowly over millennia, not rapidly over the months or years of a single life. Charles Darwin’s process of natural selection holds that nature choses the best-adapted organisms to reproduce and survive in any given ecosystem. The process operates when DNA sequences mutate randomly, and organisms with the specific sequences best-adapted to the environment multiply and prevail – causing gene expression to shift. Yet as surely as the slow march of Darwinian evolution shapes life on Earth over aeons, scientists have found that epigenetic signals can work each day, and not just through methyl groups. Experience in the environment could also alter chromatin, the molecular matrix making up our chromosomes; RNA, the messenger molecules that translate genetic instructions from DNA into protein; and histones, the proteins involved in packaging and structuring the chromatin comprising the genes.

The human brain has always loved the dopamine rush of notifications, in any form; recent research indicates the unpredictable but ubiquitous updates of Gmail or Twitter carry the same neurological effect as rocking a slot machine. While Internet use is "not addictive in the same way as pharmacological substances are," as cognitive scientist Tom Stafford noted in 2013, we continually chase those unpredictable payoffs on Facebook and Instagram in ways that tend to mirror gambling or sex addictions, even if "Internet addiction" writ large currently holds an ambiguous position in the Diagnostic and Statistical Manual of Mental Disorders.

For products whose fundamental business proposition is harnessing attention, building those so-called "compulsion loops" isn't an accident of technology—it's the whole point. Indeed, observers have argued since Parker's "human psychology" flub last year that Facebook has not just meticulously measured, but fundamentally altered human behavior, and nascent technology ventures emboldened by Facebook's world-changing success have sought to translate the behavioral tricks that psychologist B.F. Skinner applied to the gambling kiosk to every mobile app under the sun. "When a gambler feels favored by luck, dopamine is released," Natasha Schüll, author of Addiction by Design: Machine Gambling in Las Vegas, told the Guardian in March. All Facebook managed to do was find a way to miniaturize the captivating logic of the slot machine—with no cost to the user but their time and attention.

While the human brain is tremendously plastic, that doesn't mean Facebook is savagely rewiring the human brain. Indeed, the Facebook users in the Cal State–Fullerton study "showed greater activation of their amygdala and striatum, brain regions that are involved in impulsive behavior," as Live Science's Tia Ghose reported at the time. Ghose continued: "But unlike in the brains of cocaine addicts, for instance, the Facebook users showed no quieting of the brain systems responsible for inhibition in the prefrontal cortex." Facebook isn't fundamentally rewiring the structure of the human brain, but its ubiquity has the same relative effect by kicking our rewards centers into overdrive.

Those who seek a radical departure from capitalism see UBI as part of a radical platform to move away from a world in which work is central to our lives, identities and economies. In their book Inventing the Future, Alex Williams and Nick Srnicek argue that UBI is a fundamental part of delivering a new economy in which citizens have much greater freedom over when and if they work.

What this shows is that for UBI to be a viable proposition at these levels, there would need to be a fundamental transformation in the ownership of the economy. Williams and Srnicek acknowledge this, arguing that UBI will only work in combination with large scale and collectively owned automation, a reduction in the working week and a shift in social attitudes around the value of the ‘work ethic’.

Action on relative poverty is important, and inequality is not cost free. As Kate Pickett and Richard Wilkinson show in their book ‘The Spirit Level’, countries with higher rates of inequality perform worse against a range of social outcomes – physical health, mental health, drug abuse, education, imprisonment, obesity, social mobility, trust and community life.

In the 1990s, the term “modern grocery retail” was essentially a proxy for a small group of multinational grocers including Ahold, Aldi, Auchan, Carrefour, Costco, Lidl, Metro, Tesco, and Walmart. It was widely presumed that these retailers’ entry into any market would lead to the demise of the traditional trade—the family-owned grocery chains, small independent stores, and informal merchants that at the time accounted for the vast majority of grocery sales in emerging markets. The prevailing expectation was that although there would be local differences due to cultural specificities, in every country the retail landscape would eventually consist of a combination of modern formats: full-line supermarkets and hypermarkets, convenience stores, and discounters. These assumptions have been proved wrong. Global grocery giants are struggling to grow profitably in many emerging markets. Traditional trade has proved remarkably resilient. And the market and channel structures taking shape in individual emerging economies are distinct from one another, following no obvious pattern.

Built from scratch by people in poorly governed, disaster-stricken Haiti, the city is emerging as an alternative model of urban existence — and its struggle is holding out lessons for similar future pockets that spring up in the aftermath of disasters.

The UN estimates there are 65 million displaced persons in the world today, more than at any time since World War II. Most live in camps where their lives are tightly restricted by host governments. They are barred from owning land or holding jobs, destined to remain dependent on foreign aid.

Canaan is the opposite. Instead of being micro-managed, it has no formal government at all. The pioneers of Canaan formed hundreds of committees that each work on a particular task or oversee the development of a particular neighborhood. These informal power structures give street names to the dirt alleyways, and set aside space for future hospitals and schools.

As Foucault said of Bachelard a few years later, his characteristic approach was to avoid all defined hierarchies, any universal judgments: ‘He plays against his own culture with his own culture.’ He stood apart, separating himself from the mainstream, finding cracks, dissonances, minor phenomena that he could make his own. Poetry of every description was his raw material.

Indoors, in The Poetics of Space, the journey into intimacy is neatly evoked by drawers, cupboards, wardrobes and above all locks, although he warns, somewhat testily, against their use as gratuitous metaphors (and he is strongly averse to the idea of habit).

The wellbeing of the warm animal (or human) protected in its nest or cocoon or cottage from the bad weather raging outside is a primitive sense of refuge that we can all share, adult or child. The appeal of a safe haven translates into domestic architecture with such features as the accommodating Arts and Crafts inglenook, seats close by the fire, Frank Lloyd Wright’s enduring penchant for an immense fireplace buried at the core of a house, or even, a favourite 1960s touch, the conversation pit – with or without its trademark shagpile carpet.

If organised forms of political resistance could be efficiently thwarted by such a system, often by subtle assimilation rather than outright suppression, the last barricade against it was the individual’s own refusal to think and respond in the prescribed ways. The hardest task facing any emancipatory politics today is to encourage people to think for themselves, in a way that transcends simple sloganising and the dictates of instrumental reason. True critical thinking requires not just a refusal to identify with the present structures of society and commercial culture, but a deep awareness of the historical tendencies that have brought about the current impasse, and of which all present experience is composed. That impulse, compared to the project of constructively helping the system out of its own periodic crises, retains the spark of a dissidence that might just, one day, throw it into the very crisis that would prompt a general, and genuine, liberation.
