What if consciousness is not what drives the human mind?

Everyone knows what it feels like to have consciousness: it’s that self-evident sense of personal awareness that gives us a feeling of ownership and control over the thoughts, emotions, and experiences we have every day.

What if consciousness is not what drives the human mind?

Most experts believe consciousness can be divided into two parts: the experience of consciousness (or personal awareness), and the contents of consciousness, which include thoughts, beliefs, sensations, perceptions, intentions, memories and emotions.

It’s easy to assume these contents are somehow chosen, caused or controlled by our personal awareness – after all, thoughts don’t exist until we think them. But in a new research paper in Frontiers of Psychology, the researchers argue this is a mistake.

They suggest that our personal awareness does not create, cause or choose our beliefs, feelings or perceptions. Instead, the contents of consciousness are generated “behind the scenes” by fast, efficient, non-conscious systems in our brains. All this happens without any interference from our personal awareness, which sits passively in the passenger seat while these processes occur.

Put simply, we don’t consciously choose our thoughts or feelings – we become aware of them.

Not just a suggestion

If this sounds strange, consider how effortlessly we regain consciousness each morning after losing it the night before; how thoughts and emotions – welcome or otherwise – arrive already formed in our minds; how the colours and shapes we see are constructed into meaningful objects or memorable faces without any effort or input from our conscious mind.

Consider that all the neuropsychological processes responsible for moving your body or using words to form sentences take place without involving your personal awareness. The researchers believe that the processes responsible for generating the contents of consciousness do the same.

 Their thinking has been influenced by research into neuropsychological and neuropsychiatric disorders, as well as more recent cognitive neuroscience studies using hypnosis. The studies using hypnosis show that a person’s mood, thoughts, and perceptions can be profoundly altered by suggestion.

In such studies, participants go through a hypnosis induction procedure, to help them to enter a mentally focused and absorbed state. Then, suggestions are made to change their perceptions and experiences.

For example, in one study, researchers recorded the brain activity of participants when they raised their arm intentionally, when it was lifted by a pulley, and when it moved in response to a hypnotic suggestion that it was being lifted by a pulley.

Similar areas of the brain were active during the involuntary and the suggested “alien” movement, while brain activity for the intentional action was different. So, hypnotic suggestion can be seen as a means of communicating an idea or belief that, when accepted, has the power to alter a person’s perceptions or behaviour.

The personal narrative

All this may leave one wondering where our thoughts, emotions, and perceptions actually come from. The new paper argues that the contents of consciousness are a subset of the experiences, emotions, thoughts, and beliefs generated by non-conscious processes within our brains.

This subset takes the form of a personal narrative, which is constantly being updated. The personal narrative exists in parallel with our personal awareness, but the latter has no influence over the former.

The personal narrative is important because it provides information to be stored in your autobiographical memory (the story you tell yourself, about yourself), and gives humans a way of communicating the things we have perceived and experienced to others.

This, in turn, allows us to generate survival strategies; for example, by learning to predict other people’s behaviour. Interpersonal skills like this underpin the development of social and cultural structures, which have promoted the survival of humankind for millennia.

So, the researchers argue that it is the ability to communicate the contents of one’s personal narrative – and not personal awareness – that gives humans their unique evolutionary advantage.

If the experience of consciousness does not confer any particular advantage, it’s not clear what its purpose is. But as a passive accompaniment to non-conscious processes, the team doesn’t believe the phenomena of personal awareness has a purpose, in much the same way rainbows don’t. Rainbows result from the reflection, refraction, and dispersion of sunlight through water droplets – none of which serves any particular purpose.

The team’s conclusions also raise questions about the notions of free will and personal responsibility. If our personal awareness does not control the contents of the personal narrative which reflects our thoughts, feelings, emotions, actions and decisions, then perhaps we should not be held responsible for them.

In response to this, they argue that free will and personal responsibility are notions that have been constructed by society. As such, they are built into the way we see and understand ourselves as individuals, and as a species. Because of this, they are represented within the non-conscious processes that create our personal narratives, and in the way we communicate those narratives to others.

Just because consciousness has been placed in the passenger seat, does not mean we need to dispense with important everyday notions such as free will and personal responsibility. In fact, they are embedded in the workings of our non-conscious brain systems. They have a powerful purpose in society and have a deep impact on the way we understand ourselves.
