The Cognitive Bias Codex

Many (all?) cognitive biases are built-in features of the human attention-sensation-perception-memory-cognition chain of sense making processes. It would not be surprising to learn many of these biases have effects that are relevant to questions regarding how natural selection shaped humans for particular embodied functions in a particular environment. Much has been said and written about how the pre-modern environment evolution calibrated us to function within is in many respects quite different from our modern environment.

Living in the future’s past

I watched a good documentary last night titled, Living in the Future’s Past, a project organized, produced, and narrated by Jeff Bridges. It’s available through your Albuquerque Public Library account’s access to Hoopla Digital, Amazon Prime video, and other services. It lays out the modern dilemma of having a pre-neolithic brain in a Neolithic era and posits several questions that align closely with the theme of our current discussion . The film has commentary from diverse scientific experts, including Daniel Goldman (emotional and social intelligence and mindfulness). The upshot is a recurring suggestion our current brain functionality is capable of reframing our perspective and modulating our perceptions and behaviors around carefully constructed focal questions that get at what sort of future(s) we desire. I like this approach—so well in fact that I Had reserved some web domains months ago: WorldIChoose.org, WorldIChoose.com, ChooseMyWorld.org, and ChooseMyWorld.com. These domains are not active yet. They will relate to the novel I’m writing and to a related non-fiction project. Edward is onto an important approach in looking to semantics (framing, etc.).

Also, on a short-term level, cultural evolution (including language and semantics) appears much more potent a driver than physiological evolution. Given that, I recently purchased a book by an author who goes into great depth on cultural evolution. The book is Cognitive Gadgets: The Cultural Evolution of Thinking, by Cecelia Heyes. I may put it forward for a future discussion.

Humans are still evolving

From this article. See it for details.

“Evolution is an ongoing process, although many don’t realize people are still evolving. It’s true that Homo sapiens look very different than Australopithecus afarensis, an early hominin that lived around 2.9 million years ago. But it is also true that we are very different compared to members of our same species, Homo sapiens, who lived 10,000 years ago — and we will very likely be different from the humans of the future.

“What we eat, how we use our bodies, and who we choose to have kids with are just some of the many factors that can cause the human body to change. Genetic mutations lead to new traits — and with the world population now above 7 billion and rising, the chances of genetic mutations that natural selection can potentially act on is only increasing. Don’t believe us? Inverse presents three examples of recent changes to the human body.”

Winter 2020 discussion prompts

  • What is humanity’s situation with respect to surviving long-term with a good quality of life? (Frame the core opportunities and obstacles.)
  • What attributes of our evolved, experientially programmed brains contribute to this situation? (What are the potential leverage points for positive change within our body-brain-mind system?)
  • What courses of research and action (including currently available systems, tools, and practices and current and possible lines of R&D) have the potential to improve our (and the planetary life system’s) near- and long-term prospects?

Following is a list of (only some!) of the resources some of us have consumed and discussed online, in emails, or face-to-face in 2019. Sample a few to jog your thoughts and provoke deeper dives. Please add your own additional references in the comments below this post. For each, give a short (one line is fine) description, if possible.

Consciousness in Humanoid Robots

New ebook from Frontiers in Science. The blurb:

Building a conscious robot is a grand scientific and technological challenge. Debates about the possibility of conscious robots and the related positive outcomes and hazards for human beings are today no more confined to philosophical circles. Robot consciousness is a research field aimed to a unified view of approaches as cognitive robotics, epigenetic and affective robotics, situated and embodied robotics, developmental robotics, anticipatory systems, biomimetic robotics. Scholars agree that a conscious robot would completely change the current views on technology: it would not be an “intelligent companion” but a complete novel kind of artifact. Notably, many neuroscientists involved in the study of consciousness do not exclude this possibility. Moreover, facing the problem of consciousness in robots may be a major move on the study of consciousness in humans and animals.

The Frontiers Research Topic on consciousness in humanoid robots concerns the theoretical studies, the models and the case studies of consciousness in humanoid robots. Topics related to this argument are:
– the needs of a body for robot consciousness;
– robot self-consciousness;
– the capability of a robot to reason about itself, its body and skills;
– the episodic memory in a robot, i.e., the ability to take into account its operational life;
– design strategies versus developmental approaches in assessing consciousness in a robot;
– robot architectures candidates for consciousness;
– symbolic versus neural networks representations in robot consciousness;
– consciousness, theory of mind and emotions in a humanoid robot;
– measurements and assessments of consciousness and self-consciousness in a robot;
– ethical and trust issues in a conscious humanoid robot.

Cultural and genetic evolution

From this article:

“The idea that humans have cognitive instincts is a cornerstone of evolutionary psychology, pioneered by Leda Cosmides, John Tooby and Steven Pinker in the 1990s. […] This all seems plausible and intuitive, doesn’t it? The trouble is, the evidence behind it is dubious. In fact, if we look closely, it’s apparent that evolutionary psychology is due for an overhaul. Rather than hard-wired cognitive instincts, our heads are much more likely to be populated by cognitive gadgets, tinkered and toyed with over successive generations. Culture is responsible not just for the grist of the mind – what we do and make – but for fabricating its mills, the very way the mind works.”

“The evidence for cognitive instincts is now so weak that we need a whole new way of capturing what’s distinctive about the human mind. The founders of evolutionary psychology were right when they said that the secret of our success is computational mechanisms – thinking machines – specialised for particular tasks. But these devices, including imitation, mind-reading, language and many others, are not hard-wired. Nor were they designed by genetic evolution. Rather, humans’ thinking machines are built in childhood through social interaction, and were fashioned by cultural, not genetic, evolution. What makes our minds unique are not cognitive instincts but cognitive gadgets.”

“The mind of a newborn human baby is not a blank slate. Like other animals, we are born with – we genetically inherit – a huge range of abilities and assumptions about the world. We’re endowed with capacities to memorise sequences, to control our impulses, to learn associations between events, and to hold several things in mind while we work on them. […] These skills and beliefs are part of the ‘genetic starter kit’ for mature human cognition. They are crucial because they direct our attention to other people, and act as cranes in the construction of new thinking machines. But they are not blueprints for Big Special cognitive mechanisms such as imitation, mind-reading and language.”

“To be fair, evolutionary psychology did something crucially important. It showed that viewing the mind as a kind of software running on the brain’s hardware can advance our understanding of the origins of human cognition. Now it’s time to take a further step: to recognise that our distinctively human apps have been created by cultural, not genetic, evolution.”

‘Neurosexism’ debated

Neuroscientist Larry Cahill takes issue with a Feb 2019 Nature favorable book review of Gina Rippon’s The Gendered Brain: The New Neuroscience That Shatters The Myth Of The Female Brain.

Cahill’s response prompted an interview by Medium Neuroscience writer Meghan Daum.

Scientific findings have a way of upsetting apple carts, especially when we consider our oft-demonstrated human capacity to bend science to advantage some power-coveting groups over others.

Valid research amply shows there are real differences in male and female neuroanatomy and functions. Honest science must follow the evidence where it leads. Clearly, any discovered differences cannot be allowed to justify unequal social or economic opportunities or treatment. Cahill compares the situation to genetics. That people differ genetically in a vast number of ways cannot be taken as cause to misstate scientific findings or preclude further learning about genetics.

There are times and circumstances in which certain research approaches must be blocked for humane or other reasons but that is a different argument than denying the findings of a body of research because they are uncomfortable or inconvenient.

the evolution of synergy

Good quick summary of some of Deacon’s ideas. Deacon: “We need to stop thinking about hierarchic evolution in simple Darwinian terms. We need to think about it both in terms of selection and the loss of selection or the reduction of selection. And that maybe it’s the reduction of selection that’s responsible for the most interesting features” (9:40).

The agency of objects

An interesting take on the agency of artifacts in light of the discussion of memes and temes. From Sinha, S. (2015). “Language and other artifacts: Socio-cultural dynamics of niche construction.” Frontiers in Psychology.

“If (as I have argued) symbolic cognitive artifacts have the effect of changing both world and mind, is it enough to think of them as mere ‘tools’ for the realization of human deliberative intention, or are they themselves agents? This question would be effectively precluded by some definitions of agency […] In emphasizing the distinction, and contrasting agents with artifacts, it fails to engage with the complex network of mediation of distinctly human, social agency by artifactual means. It is precisely the importance of this network for both cognitive and social theory that Latour highlights by introducing the concept of ‘interobjectivity.’ […] Symbolic cognitive artifacts are not just repositories, the are also agents of change. […] We can argue that the agency is (at least until now) ultimately dependent on human agency, without which artifactual agency would neither exist nor have effect. But it would be wrong to think of artifactual agency as merely derivative.”
