"Why did the experience of consciousness evolve from our underlying brain physiology? Despite being a vibrant area of neuroscience, current research on consciousness is characterised by disagreement and controversy – with several rival theories in contention.

***

"We define consciousness as embodied subjective awareness, including self awareness. In a recent article published in Interalia (which is not peer reviewed), we argue that one reason for this predicament is the powerful role played by intuition.

***

"Key intuitive beliefs – for example that our mental processes are distinct from our physical bodies (mind-body dualism) and that our mental processes give rise to and control our decisions and actions (mental causation) – are supported by a lifetime of subjective experiences.

"These beliefs are found in all human cultures. They are important as they serve as foundational beliefs for most liberal democracies and criminal justice systems. They are resistant to counter evidence.

"That's because they are powerfully endorsed by social and cultural concepts such as free will, human rights, democracy, justice and moral responsibility. All these concepts assume that consciousness plays a central controlling influence.

"Intuition, however, is an automatic, cognitive process that evolved to provide fast trusted explanations and predictions. In fact, it does so without the need for us to know how or why we know it.

The outcomes of intuition therefore shape how we perceive and explain our everyday world without the need for extensive reflection or formal analytic explanations.

"While helpful and indeed crucial for many everyday activities, intuitive beliefs can be wrong. They can also interfere with scientific literacy.

***

"While there is no current scientific explanation for how brain tissue generates or maintains subjective experience, the consensus among (most) neuroscientists is that it is a product of brain processes.

"If that's the case, why did consciousness, defined as subjective awareness, evolve?

"Consciousness presumably evolved as part of the evolution of the nervous system. According to several theories the key adaptive function (providing an organism with survival and reproductive benefits) of consciousness is to make volitional movement possible.

"And volition is something we ultimately associate with will, agency and individuality. It is therefore easy to think that consciousness evolved to benefit us as individuals.

"But we have argued that consciousness may have evolved to facilitate key social adaptive functions. Rather than helping individuals survive, it evolved to help us broadcast our experienced ideas and feelings into the wider world. And this might benefit the survival and wellbeing of the wider species.

***

"Central to our account is the idea that sociality (the tendency of groups and individuals to develop social links and live in communities) is a key survival strategy that influences how the brain and cognition evolve.

***

"While it is counter-intuitive to attribute agency and personal accountability to a biological assembly of nerve cells, it makes sense that highly valued social constructs such as free will, truth, honesty and fairness can be meaningfully attributed to individuals as accountable people in a social community.

"Think about it. While we are deeply rooted in our biological nature, our social nature is largely defined by our roles and interactions in society. As such, the mental architecture of the mind should be strongly adapted for the exchange and reception of information, ideas and feelings.

"Consequently, while brains as biological organs are incapable of responsibility and agency, legal and social traditions have long held individuals accountable for their behaviour.

"Key to achieving a more scientific explanation of subjective awareness requires accepting that biology and culture work collectively to shape how brains evolve. Subjective awareness comprises only one part of the brain's much larger mental architecture designed to facilitate species survival and wellbeing." (my bold)

Comment: social animals like bonobos live in social groups without our self-awareness. All ape families are in groups, as are many monkey species. These authors have it all backwards. Our complex brain gave us these unnecessary gifts from design. But I agree societal interaction aids survival.
