Jared Janes on meditation and spirituality

Jim Rutt interviews him here. The blurb:

Meditator  and thinker Jared Janes talks with Jim about why he still uses the word ‘spiritual’, altered states vs altered traits, the equation and dynamics of suffering, understanding our own intentions, the confabulating mind, embodied intuition, the value and limits of conceptuality, what the self is and its usefulness, attention and awareness, the pleasure of concentration, metaphysics, and more.

Jared Janes is a podcast producer/host (The Jim Rutt Show, Both/And,  and Impactful), a management consultant, and a committed meditator. He’s been a daily meditator for over five years, has completed multiple meditation courses from different traditions, attends multiple meditation retreats each year, and personally coaches meditators in his spare time. Before podcasting and consulting he built a career in digital operations and management, started and ran a nonprofit, played a video game semi-professionally, and spent his spare time learning about personal performance, science and philosophy.

More on Haidt

Continuing this previous post:

I’m looking at the section “conclusion and critique” of Haidt starting on p. 31. Gibbs appreciates that we should account for our earlier human history and more primitive brain centers in describing morality. But to limit it to these structures and history at the expense of later brain structures and evolutionary development is another thing.

“The negative skew in Haidt’s descriptive work discourages study in moral psychology of higher reaches of morality such as rational moral reflection, empathy for the plight of entire out-groups, moral courage, and the cultivation of responsible, mature moral agency —broadly, study of ‘the scope of human possibilities, of what people can do morally, if they are prepared, through development and education, to approach life’s important issues in a thoughtful way’” (34).

Several neuroscientific studies make clear which parts of the brain are emphasized in liberals and conservatives. The amygdala (indicative of fight or flight fear) is a much older evolutionary brain structure, while the anterior cingulate cortex (higher thinking functions) much newer. Hence there is neuroscientific brain evidence for the evolution of morality per Kohlberg. Haidt admits that conservative morality is rooted in these more evolutionary earlier brain structures, and liberal morality in the newer structures.

The newer neocortex then coordinates and integrates the older brain functions so that the latter do not dominate and send us backward in evolution. It’s not that liberals don’t have the conservative moral traits like Haidt claims; it’s that those earlier evolutionary traits are now modified under neocortex control. Yes, there is a value judgment involved here, but it’s supported by evolutionary science, not ideology.

The abstract from “Neural correlates or post-conventional moral reasoning”:

“Going back to Kohlberg, moral development research affirms that people progress through different stages of moral reasoning as cognitive abilities mature. Individuals at a lower level of moral reasoning judge moral issues mainly based on self-interest (personal interests schema) or based on adherence to laws and rules (maintaining norms schema), whereas individuals at the post-conventional level judge moral issues based on deeper principles and shared ideals. However, the extent to which moral development is reflected in structural brain architecture remains unknown. To investigate this question, we used voxel-based morphometry and examined the brain structure in a sample of 67 Master of Business Administration (MBA) students. Subjects completed the Defining Issues Test (DIT-2) which measures moral development in terms of cognitive schema preference. Results demonstrate that subjects at the post-conventional level of moral reasoning were characterized by increased gray matter volume in the ventromedial prefrontal cortex and subgenual anterior cingulate cortex, compared with subjects at a lower level of moral reasoning. Our findings support an important role for both cognitive and emotional processes in moral reasoning and provide first evidence for individual differences in brain structure according to the stages of moral reasoning first proposed by Kohlberg decades ago.”

From Mendez, M. (2017). “A neurology of the conservative-liberal dimension of political ideology.” The Journal of Neuropsychiatry and Clinical Neurosciences.

“Differences in political ideology are a major source of human disagreement and conflict. There is increasing evidence that neurobiological mechanisms mediate individual differences in political ideology through effects on a conservative-liberal axis. This review summarizes personality, evolutionary and genetic, cognitive, neuroimaging, and neurological studies of conservatism-liberalism and discusses how they might affect political ideology. What emerges from this highly variable literature is evidence for a normal right-sided cconservative-complex’ involving structures sensitive to negativity bias, threat, disgust, and avoidance.”

Book: Range: Why Generalists Triumph in a Specialized World

In his new book, Range: Why Generalists Triumph in a Specialized World, David J. Epstein investigates the significant advantages of generalized cognitive skills for success in a complex world. We’ve heard and read many praises for narrow expertise in both humans and AIs (Watson, Alpha Go, etc.). In both humans and AIs, however, narrow+deep expertise does not translate to adaptiveness when reality presents novel challenges, as it does constantly. 

As you ingest this highly readable, non-technical book, please add your observations to the comments below. 

Syntegration: The key to innovation

This TED talk discusses how tech innovation is driven by those with diverse experience that syntegrate a variety of genres instead of specialists that are limited to a few. They call it ‘lateral’ thinking but that term sets up a dichotomy with hierarchical thinking, which the syntegral approach is certainly much more than. The hierarchical complexity approach would limit that way of thinking merely to what it calls horizontal complexity, again missing the boat entirely of the sort of cross-paradigmatic thinking involved in syntegration, aka hier(an)archical synplexity.

how does music affect the brain?

The blurb:

“In this episode of Tech Effects, we explore the impact of music on the brain and body. From listening to music to performing it, WIRED’s Peter Rubin looks at how music can change our moods, why we get the chills, and how it can actually change pathways in our brains.”

For me the most interesting part was later in the video (10:20), how when we improvise we shut down the pre-frontal planning part of the brain and ‘just go with the flow,’ which is our most creative and innovation moments. This though does depend on having used the pre-frontal cortex in learning the techniques of music to get them so ingrained in memory that we are then free to play with what we’ve programmed.

Neural Correlates of Post-Conventional Moral Reasoning

Informative neuroscience presentations at NYU Center for Mind, Brain & Consciousness

The NYU Center for Mind, Brain & Consciousness hosts presentations, including topical debates among leading neuroscience researchers. Many of the sessions are recorded for later viewing. The upcoming debate among Joseph LeDoux (Center for Neural Science, NYU), Yaïr Pinto (Psychology, University of Amsterdam), and Elizabeth Schechter (Philosophy, Washington University in St. Louis), will tackle the question, “Do Split-brain patients have two minds?” Previous topics addressed animal consciousness, hierarchical predictive coding and perception, AI ‘machinery,’ AI ethics, unconscious perception, research replication issues, neuroscience and art, explanatory power of mirror neurons, child vs adult learning, and brain-mapping initiatives.

Neurofeedback as a tool to modulate cognition and behavior

Article here from Frontiers in Human Neuroscience, 2017, 11:51.  The abstract (note my italicized highlighting):

“Neurofeedback is attracting renewed interest as a method to self-regulate one’s own brain activity to directly alter the underlying neural mechanisms of cognition and behavior. It not only promises new avenues as a method for cognitive enhancement in healthy subjects, but also as a therapeutic tool. In the current article, we present a review tutorial discussing key aspects relevant to the development of electroencephalography (EEG) neurofeedback studies. In addition, the putative mechanisms underlying neurofeedback learning are considered. We highlight both aspects relevant for the practical application of neurofeedback as well as rather theoretical considerations related to the development of new generation protocols. Important characteristics regarding the set-up of a neurofeedback protocol are outlined in a step-by-step way. All these practical and theoretical considerations are illustrated based on a protocol and results of a frontal-midline theta up-regulation training for the improvement of executive functions. Not least, assessment criteria for the validation of neurofeedback studies as well as general guidelines for the evaluation of training efficacy are discussed.”

Book discussion event on embodied cognition

Our discussions all, to some extent, relate to cognition. An important area of inquiry concerns whether some form of physical embodiment is required for a brain to support cognition in general and the self-aware sort of cognition we humans possess.

THE BOOK

Philosophy In The Flesh: The Embodied Mind And Its Challenge To Western Thought, by George Lakoff and Mark Johnson. Please note, while the title includes “Philosophy,” we are not a philosophy group and the book and discussion will revolve around scientific concepts and implications, not spiritualistic or metaphysical ideas.

Free Frontier e-books July 2018

Here‘s the link to their lineup of new free e-books. Maybe we could even use one of them for a book discussion? I’m inclined toward the one titled Insight and Intuition: Two Sides of the Same Coin? Their blurb for the latter:


In the field of intuition it is widely accepted that problem solving proceeds in a more or less graded fashion from problem formulation to problem solution as previously encoded information is activated by clues to coherence. The resulting pattern of activation differentially sensitizes a person to new information that is pertinent for the solution. Eventually, the continuous (and rapid) build-up of coherent information is sufficient to cross a threshold of awareness or noticing. Accordingly, implicitly acquired knowledge and experience play an important role because their content is assumed to be non-consciously and gradually activated in memory from clues in the environment that initiate an automatic spreading of activation. These assumptions are summarized in what has been known as the continuity model of intuition.

On the contrary, the current literature on insight problem solving favors a discontinuity model. Particularly, insight is linked to processes that restructure the mental representation of a problem. It is assumed that prior knowledge and inappropriate assumptions result in self-imposed constraints that establish a biased representation of the problem and thus prevent a solution. Consequently, a discontinuity model suggests the first intuitive apprehension of the problem to lead to an impasse and has to be overcome by relaxing these constraints to find a solution.

Until now, there has neither been theoretical discussion nor empirical investigation on the continuity/discontinuity distinction. Our open research questions include the following:

1. Are continuity/discontinuity different sides of the same coin distinguishing different stages within a continuous solution process, or do they stand for mutual exclusive processes?
2. If intuition is seen as “coherence building mechanism”, is it conceivable to describe the different stages within insight problem solving as coherence changing processes?
3. What are the underlying neuro-cognitive mechanisms that allow the search for coherence, respectively the change of coherence (representational change)? Both processes might go beyond a simple spreading activation account.
4. How does re-combination and the generation of new and novel solutions fit into the intuitive framework?
5. Could the application of Darwinian principles help to inform us about the underlying principles of both?
