06-03-2026 ~ Research suggests that human consciousness evolved as a cognitive filter, privileging and amplifying human-communicative inputs as a foundation for transmissive teaching and learning, language development, and, ultimately, cultural evolution and culture itself.

This piece explores human consciousness as the foundational engine of culture, tracing its evolution from early social learning in infants to the sophisticated shared meanings of prehistoric human communities. It examines how social consciousness—joint attention and reciprocal mirroring—enabled humans to transmit knowledge, develop language, and coordinate culturally, creating a feedback loop between individual and collective consciousness. The article draws on biology, anthropology, and linguistics, including case studies like Nicaraguan Sign Language, to illustrate how shared meaning emerges. Its central argument: consciousness facilitates transmissive teaching and learning, which underpins human cultural evolution and the cumulative growth of knowledge across generations.

Consciousness as Cognitive Filter 
Research suggests that human consciousness evolved as a cognitive filter, privileging and amplifying human-communicative inputs as a foundation for language development, transmissive teaching and learning, and, ultimately, culture.

Fortunately, humans do not wait for a full understanding of things before they converse about them. Love is a good example, perhaps the best one. We have been talking about, singing about, painting, and dancing around “love” almost certainly from the beginning of our species’s communicative existence, and yet, what exactly love is, is a real question we could take up in earnest at any time without embarrassment. The same goes for concepts like maturity, character, respect, common sense, trust, leadership, normalcy, and, of course, consciousness. We can often do no better than to say merely that we know these things when we see them.

When humans do recognize consciousness, they tend to agree on a set of similar intuitive descriptions: it is like an inner self capable of observing our mental activity, an inner witness, or a piece of cerebral machinery that equips its owner with the sense that “I am” and “what it’s like to be me.”

We tend to speak of consciousness as something uniquely human, even after accounting for our scientific ignorance and allowing for the possibility of consciousness in “lower” animals, individual cells, or the entire universe.

Biological science furnishes us with its own constraining assumptions and intuitions about human consciousness: it likely evolved in some way across vast expanses of time; its roots likely stretch far back into prehistory; and it likely served, and perhaps continues to serve, an important purpose or set of purposes for the human species that possesses it, purposes that remain a mystery.

To this array of conversational and scientific intuitions, let us add those of archaeologists and anthropologists. The appearance of sophisticated tool refinement, the creation of art, the rise of elaborate burials, and the evolution of organized communities in the archaeological record are physical marks that are quintessentially human, indicators of consciousness, and as mysterious as they are.

It is likely that our various intuitions about consciousness are mostly true and that the mysteries connect. That is, human consciousness not only supplies us with a seemingly dualistic sense of “inner self” but also the one that represents the first click of the ratchet effect—the process responsible for cultural evolution and believed to be behind organized settlements, tool refinement, and art.

An infant sticks out its tongue, and their parent sticks out theirs. This phenomenon is known as human reciprocal mirroring. It is how social learning occurs. The infant imitates, then, crucially, pauses to monitor the parent’s reaction. Although non-human apes can occasionally manage this kind of behavioral imitation, they do not engage in reciprocal mirroring. In human infant-parent communication, each is aware that the other is aware that they are aware, a recursive process that represents an alignment of consciousness that goes back to the start of life. The infant is ready to be both observer and participant, actor and audience. It just needs the content of human social life (the scenes, experience, and knowledge) to start putting meat on the bones of this “inner self,” which is shaped by a rapidly changing social world. This same process of experience and learning from others is what gives social learning its footing. Nearly everything the infant will learn in its life will occur through this process.

What this exchange shows is that human consciousness, both social and individual, is what makes cumulative human culture possible. From the start, the mind is built to align with other minds, allowing knowledge to move between people and persist across time. Meaning is not merely passed along but stabilized and carried forward through this recursive awareness, so that what is learned does not vanish with the learner but becomes part of a shared, revisitable world.

How did our species arrive at this moment where all of its newest members are ready to learn, quickly and accurately, how to communicate?

Social Consciousness
Our story is generally thought to have started around 300,000 to 400,000 years ago with the consolidation of human social consciousness. This capacity can be described as “the spontaneous adoption of another person’s perspective,” as in the relationship between a parent and their infant. The increasing strength of this mutual attention in humans—especially, among groups of humans—gradually allowed for the generation of joint representations, or ‘objectified,’ agreed-upon percepts from the surrounding natural and social environments.

Human social consciousness—a term used here as an alternative to joint attention—forms both a literal and a figurative breeding ground for the consciousness we experience now. In simple terms, it can be understood as a communication channel. We witnessed this when the parent and infant were sticking out their tongues; joint attention automatically opens a channel, and the participants, parent and infant, communicatively imitate each other within it. Opening of communication channels also happens in larger groups, even with strangers. Each channel internally represents shared meanings, called joint representations, and participants can now point, imitate, use gestures and movements, vocal pitch, and other, even unintended, signals to coordinate within and across these social situations and explore them. The unconscious, automatic nature of this process is something we very much take for granted. For example, we will follow others across the street at a crosswalk, against the light, even though we are total strangers who have never spoken a word to each other, and never will again. We know without trying that everyone has the same joint representation. Read more

Despite Climate Policy Setbacks, A Just Transition Is Still Within Reach

• by: C.J. Polychroniou

Prof.dr. Robert Pollin

06-03-2026 ~ Many US states have the ability to implement climate stabilization programs and become carbon-neutral by 2050.

The evidence for rapid human-caused climate change keeps piling up, yet the world continues to flood the atmosphere with greenhouse gases amid a political backlash against the struggle for a future free of fossil fuels. Greenhouse gas emissions continue to grow, which means humans are continuing to make the climate crisis worse. Global average temperatures are expected to stay at record levels for the 2026-2030 period, exceeding preindustrial averages by more than 1.5 degrees Celsius. As global warming speeds up, events like wildfires, droughts, hurricanes, and floods will become more intense, and there will be a substantial increase in premature deaths, with the overwhelming majority occurring in low-and middle-income countries. The climate crisis presents a grave threat to life on Earth, although scientists have now scrapped the worst-case climate scenario on account of the expansion of renewable energy — which means there is still hope.

In the interview that follows, world-renowned economist Robert Pollin talks about the forces resisting green transition and highlights the results of a major study he and some of his co-workers at the Political Economy Research Institute (PERI) produced for advancing a green transition in Michigan. According to Pollin, there are simply no technical or economic considerations preventing Michigan and other U.S. states from achieving carbon neutrality by 2050. Pollin is distinguished professor of economics and co-director of PERI at the University of Massachusetts Amherst.

C. J. Polychroniou: Over the past few years, we have observed the climate crisis taking a back seat to geopolitical conflicts and wars, but also to immediate economic concerns such as inflation. Indeed, climate action is colliding with political and economic realities and, subsequently, climate change is no longer a top issue in the international policy agenda. Moreover, U.S. Energy Secretary Chris Wright has called the International Energy Agency’s (IEA) net zero modeling “ridiculous” and European leaders themselves are also divided over the pace of the green transition. Why would a green transition be fueling backlash, and what might be the consequences of more inaction on climate change?

Robert Pollin: By far, the largest factor driving the global climate crisis is the burning of oil, coal, and natural gas to produce energy. This is because burning fossil fuels to produce energy generates carbon dioxide (CO₂) emissions. In turn, the accumulated stock of CO₂ in the atmosphere is the primary source of rising average global temperatures.

Once we start from these straightforward facts, it becomes obvious as to why there is a global pushback against a green transition project. While burning fossil fuels to produce energy is driving the climate crisis, it is also delivering gigantic profits for fossil fuel corporations. A recent Oxfam study projects 2026 profits for the six largest fossil fuel corporations — Chevron, Shell, BP, ConocoPhillips, Exxon, and TotalEnergies — to reach $94 billion. These companies and their shareholders are not about to surrender $94 billion without a fight. Such cash piles also make it easy to buy off politicians. Donald Trump leads the pack here, such as with his ridiculous pronouncement last September before the UN General Assembly that the climate crisis is “the greatest con job in history.”

But it’s not just greedy corporations and corrupt politicians who resist the green transition. Not surprisingly and with good reason, it also includes a fair share of working people whose livelihoods are tied to the fossil fuel industry as well as governments which depend on fossil fuel tax revenues to finance their social spending. For example, the state of New Mexico finances nearly half of its entire state budget through oil and gas tax revenues. Figuring out alternative funding sources to pay New Mexico’s public school teachers and health care workers is not obvious.

Of course, none of this means that giving up on the green transition is an option. The reality of the climate crisis doesn’t just go away. A widely reported recent study did lower its high-end forecast of the extent of global warming up to the year 2100, from 5.0 degrees to 3.5 degrees Celsius (C) above preindustrial levels — 9.0degrees to 6.3degrees Fahrenheit (F). But let’s put this new estimate in context. To date, the extent of global warming is at 1.4 degrees C (2.5 degrees F) — i.e., nowhere close to an increase of 3.5 degrees C, much less of 5 degrees C. The severe consequences of this 1.4degrees C of global warming are before our eyes. Average daily high temperatures this past April in New Delhi, a metropolitan area of 35 million people, were 109degrees F (43 degrees C). This past May, a major heat wave broke temperature records across northwest Europe, triggering water shortages in the U.K. and causing several deaths in France. Read more

We Need A Care Package!

06-01-2026 ~ We’ve built an economy that depends on unpaid and underpaid care, but penalizes the people who provide it.

Eighty years ago, an organization named CARE—which stands for Cooperative for Assistance and Relief Everywhere—responded to worldwide hunger in the aftermath of World War II by sending millions of packages of food. This post commemorates that effort.

A diverse group of researchers and policy advocates met recently at the Political Economy Research Institute (PERI) at the University of Massachusetts Amherst to brainstorm and draft proposals for “game-changing” policies for the U.S. economy. As part of this larger effort, I led a small team asking a simple but profound question: what would our economy look like if we took seriously the work of caring for one another?

The short answer: not like what we have.

In the United States, we rely on a patchwork of underfunded programs, unpaid labor (mostly by women), and heroic improvisation by families trying to hold things together. We treat care as a private burden rather than a public good. And then we act surprised when the system produces stress, inequality, and declining confidence in the future.

Three bold, interconnected proposals—universal child care, paid family and medical leave plus long-term care support, and a monthly child allowance—would transform life for American families. Together, they form a coherent package that addresses caregiving at every stage of life: from infancy through old age. Other wealthy nations have already figured this out. It’s long past time the United States did too.

These proposals would work together to give families the flexibility they need. They build on policies that have already been put in place by individual states or experimented with at the federal level. They are game-changers because they are all conceived as free, universal benefits that would be funded by taxes on income from capital, rather than from labor (stay tuned for further reports from the Game-Changers: Economic Policies for a Working America project).

Free Child Care for Every Family
Let’s start with the basics: raising children costs money, and right now, most of that cost falls squarely on parents. Child care alone can run tens of thousands of dollars a year. The United States currently spends less than half as much of its GDP on early childhood programs as comparable wealthy nations do—a startling gap that has real consequences. One recent study put the cost of inadequate child care at $122 billion in lost earnings and productivity every year.

The proposal here is simple: fully universal, federally funded child care and early education services for all children from birth through school age. Not a voucher program. Not a means-tested subsidy that phases out just when families need it most. A real public system, the way we have public schools—because, as the proposal puts it, parents are “raising the next generation of workers and taxpayers,” and society has a stake in that.

This isn’t a fantasy. New Mexico launched free universal child care in 2025. The program, which evolved from an earlier expansion of child-care assistance begun in 2022, is funded largely through revenues connected to the state’s oil and gas wealth and the Early Childhood Education and Care Fund. Parents and teachers joined forces to make it happen.

The U.S. military has run a high-quality subsidized child care system for decades. France, Denmark, Sweden—country after country has also made this work. Several American cities, including New York City, Boston, Seattle, San Antonio, and Washington, D.C., are already investing in public child care on their own.

What would a federal program like this cost? Based on earlier estimates, somewhere in the range of $150–$200 billion annually. That sounds like a lot until you compare it to the proposed $1.5 trillion “defense” budget for next fiscal year. Read more
