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.
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).
“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.”
Misleading and sensationalist news personalities have ceased to be noteworthy. They are the norm in American mainstream media. Interviewers strive to oversimplify and shape guests’ messages–tactics interviewees who are good communicators can cast in sharp relief. Experts tend to present information in systemic, relational, and process terms no longer welcome in or compatible with the aims of popular media outlets.
A fascinating article in The Atlantic not only surfaces these tactics (which may have become habits more than deliberate interviewing methods) but highlights the challenge any expert or systems thinker faces when attempting to convey concepts of any complexity or nuance.
I also found the interviewee’s (a sociologist) points very interesting in themselves. For example,
Peterson (expert): There’s this idea that hierarchical structures are a sociological construct of the Western patriarchy. And that is so untrue that it’s almost unbelievable. I use the lobster as an example: We diverged from lobsters evolutionarily history about 350 million years ago. And lobsters exist in hierarchies. They have a nervous system attuned to the hierarchy. And that nervous system runs on serotonin just like ours. The nervous system of the lobster and the human being is so similar that anti-depressants work on lobsters. And it’s part of my attempt to demonstrate that the idea of hierarchy has absolutely nothing to do with sociocultural construction, which it doesn’t.
Newman (journalist): Let me get this straight. You’re saying that we should organize our societies along the lines of the lobsters?
It would be funny as an SNL skit, but as a supposed demonstration of professional journalism, it is a sad commentary on the state of affairs.
More in line with this group’s focus is Peterson’s point on the evolutionary reality of the hierarchical organization of species, including humans. Of course, this was not a moral or political statement, but a reference to neurochemical bases for perceptions and behaviors.
I appreciate that in our discussions we can press into more nuanced conceptual territories than Ms. Newman was willing to allow Dr. Peterson.
