E49: Metaphors and the predictive brain

E49: Metaphors and the predictive brain

Author: Brian Marick May 20, 2025 Duration: 19:27

It's fairly pointless to analyze metaphors in isolation. They're used in a cumulative way as part of real or imagined conversations. That meshes with a newish way of understanding the brain: as largely a prediction engine. If that's true, what would it mean for metaphorical names in code?

Brian Marick hosts Oddly Influenced, a podcast that digs into the unusual and often overlooked connections between software development and the wider world. Each episode starts with a concept, theory, or practice that originated far from the realm of code-perhaps in sociology, theater, history, or urban planning-and traces its journey into the hands of software practitioners. The focus is on the concrete application: how these borrowed ideas were adapted, what problems they aimed to solve, and what actually happened when people tried them. You’ll hear about the successes, the surprising failures, and the messy, fascinating reality of translating an abstract principle into working practice. This isn’t about generic inspiration or vague parallels; it’s a detailed look at cross-disciplinary pollination, examining the mechanics of how influence actually works. The conversations are grounded and specific, avoiding hype to explore what we can genuinely learn from fields that don’t think in loops and logic. For anyone in technology or education curious about how innovation often comes from the edges, this podcast provides a unique and thoughtful perspective. It’s for listeners who enjoy deep dives into the history and sociology of their craft, who appreciate hearing stories that aren’t the usual case studies, and who are open to having their own thinking oddly influenced by the end of an episode.

E50: the preferred level of abstraction (a nugget) [not-audio_url] [/not-audio_url]

Duration: 16:00
We see a creature near us, and we describe it as a dog. Why that and not "mammal" or "animal"? And if that dog's a Springer Spaniel, and we know it's a Springer Spaniel, why do we nevertheless call it a "dog"? In an appa…
E48: Multiple metaphors [not-audio_url] [/not-audio_url]

Duration: 27:29
When we name a class name `Invoice`, are we communicating or thinking metaphorically? I used to think we were; now I think we aren't. This episode explains one reason: ordinary conversation frequently uses multiple metap…

In 1970, Winston W. Royce published a paper “Managing the Development of Large Software Systems.” Later authors cited it as the justification for what had come to be called the "waterfall process." Yet Royce had quite sp…
E46: How do metaphors work? [not-audio_url] [/not-audio_url]

Duration: 32:07
Conceptual metaphor is a theory in cognitive science that claims understanding and problem-solving often (but not always) happen via systems of metaphor. I present the case for it, and also expand on the theory in the li…
E45: The offloaded brain, part 5: I propose a software design style [not-audio_url] [/not-audio_url]

Duration: 38:06
In this episode, I ask the question: what would a software design style inspired by ecological and embodied cognition be like? I sketch some tentative ideas. I plan to explore this further at nh.oddly-influenced.dev, a b…

Duration: 43:55
In the '80s, David Chapman and Phil Agre were doing work within AI that was very compatible with the ecological and embodied cognition approach I've been describing. They produced a program, Pengi, that played a video ga…

Duration: 25:42
Scientists studying ecological and embodied cognition try to use algorithms as little as they can. Instead, they favor dynamical systems, typically represented as a set of equations that share variables in a way that is…
