Our Genetic Timebomb

“The yaksha asked: “What is the greatest surprise?” Yudhisthira replied: “People die every day, making us aware that men are mortal. Yet we live, work, play, plan, etc., as if assuming we are immortal. What is more surprising than that?
— The Mahabharata“

Every few days or weeks, Rob Mielcarski posts to his Un-Denial blog some or another nuance to the Mind Over Reality Transition (MORT) theory of Varki and Brower (2013). If you are not aware of MORT, the idea in a nutshell is that somewhere in the evolution of human neurobiology there came a moment when we were so freaked out by recognition of our own mortality (after ritualistically consuming a paranoia-inducing mushroom like Amanita muscaria perhaps), that we hard-wired a capacity to deny our own mortality and take on blind faith that every-day-reality is too unreliable to put complete trust in.

“We are polluting the earth and changing the climate in ways that we can’t predict, and likely at some point, can’t easily reverse. If we’re so smart, why do we continue to sow the seeds for our eventual destruction? Because we are saddled with a brain that is designed by selection to cope with the ultimate disaster (death) by denying that it will occur, and so we treat other impending disasters by denying that they will ever happen ……Indeed, it is arguable that we are destined ultimately to destroy ourselves as a species.”

Some aspects of human cognition and behavior appear unusual or exaggerated relative to those of other intelligent, warm-blooded, long-lived social species — including certain mammals (cetaceans, elephants, and great apes) and birds (corvids and passerines). One collection of such related features is our remarkable ability for ignoring or denying reality in the face of clear facts, a high capacity for self-deception and false beliefs, overarching optimism bias, and irrational risk-taking behavior (herein collectively called “reality denial”). Such traits should be maladaptive for reproductive success when they first appear as consistent features in individuals of any species. Meanwhile, available data suggest that self-awareness (knowledge of one’s own personhood) and basic theory of mind (ToM, also termed mind-reading, intentionality, etc.) have evolved independently several times, particularly in the same kinds of species mentioned above. Despite a long-standing opportunity spanning tens of millions of years, only humans appear to have gone on to evolve an extended ToM (multilevel intentionality), a trait required for optimal expression of many other unusual cognitive attributes of our species, such as advanced linguistic communication and cumulative cooperative culture.

Most human behaviors exist in other species on a continuum of development, as one would expect from evolution. But religion appears to be a well-established near universal only in human cultures and there are many obvious fitness advantages that have been discussed by others. But most of these advantages should not require a belief in life after death. Nevertheless, almost all religions have at their core some form of such afterlife beliefs, which would serve as another mechanism to blunt the impact of mortality salience. Of course, atheists do not live in constant fear of their mortality, so the underlying reality denial appears to be the primary mechanism.

Could the well-known human craving for mind-altering substances also be partly due to the need to escape reality? Could the same be true of the positive value of meditation methods that focus on mindfulness of the present, or the shutting out of irksome reality? Conversely, could episodic panic attacks represent a sudden failure of the neural mechanisms of reality denial?

Mielcarski, following in the footsteps of Brower and Varki, says that it is impossible for high intelligence to exist without reality denial. At the same time, reality denial is a ticking time bomb embedded into the entire human experiment. Reality denial is what stands between our existential climate emergency and the simple, relatively cost-free, natural climate solutions I have been describing here for the past 532 posts or in the prior two decades of publishing the quarterly Natural Rights in hard copy. Reality denial is what crashed the recent COP25 climate conference in Madrid, pushing off a hard deadline imposed by physical reality. Reality denial is what allowed the UK to re-empower Boris Johnson, US to elect Trump, Brazil to elect Bolsonaro, India to elevate Modi, and so forth. All of those nasty tendencies to act counter to our own best interest are programmed into the central processing unit in our genetic mainframe. It is not like we can go in and do a bug-patch. This is not software. The MORT trait passes whole and entire in our mitochondria every time one of our cells divides.

Humans should never think of themselves as smart or intelligent, they’re simply a thermodynamic event maintaining homeostasis through gradient reduction. Their entire mentality serves energy/wealth acquisition, consumption and reproduction. Being a social mammal (obtaining energy as a group) they are hierarchically organized and are constantly striving to improve their social standing by whatever means possible (if they haven’t yet seen the futility in such efforts). Those able to control the most money/energy are admired and envied by their sycophants while those with less success are regularly scorned and often deemed unworthy of reproduction or even living. Just as the human civilization will enslave, consume and/or deprive other species of their ability to live and reproduce, so too wealthy humans will enslave less avaricious humans and use them for self-enrichment.

This is my song, O God of all the nations
A song of peace, for lands afar and mine
This is my home, the country where my heart is
Here are my hopes, my dreams, my holy shrine
But other hearts in other lands are beating
With hopes and dreams as true and high as mine

My country’s skies are bluer than the ocean
And sunlight beams on clover leaf and pine
But other lands have sunlight too, and clover
And skies are everywhere as blue as mine
Oh hear my song, thou God of all the nations
A song of peace for their land and for mine
