E50: the preferred level of abstraction (a nugget)

E50: the preferred level of abstraction (a nugget)

Author: Brian Marick June 8, 2025 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 apparent digression, I discuss the idea in cognitive science of a "basic level of categorization" (or abstraction). While we construct hierarchies and taxonomies, we tend to operate at one specific level: one that's not too abstract and not too concrete.

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.
