The Voltage Paradox: Why Great Ideas Often Fail at Scale
Why do so many brilliant innovations fizzle when expanding? For every Netflix or iPhone that revolutionizes an industry, countless promising concepts collapse under the weight of growth. This phenomenon-what economist John List calls "the voltage effect"-explains why scaling breaks most ideas, regardless of their initial promise. My journey into scaling science began unexpectedly while studying baseball card markets as an undergraduate. This early fieldwork taught me to see the world as my laboratory-a perspective that would later take me from Chicago preschools to the White House, and eventually to rideshare giants Uber and Lyft. Along the way, I discovered that most ideas lose voltage when scaled, not randomly, but following predictable patterns. Some ideas appear successful in small tests but contain fatal flaws that only emerge at scale. Others work brilliantly in controlled environments but fail when confronting real-world complexity. The most heartbreaking are those that genuinely work but collapse under implementation challenges or runaway costs. The stakes couldn't be higher. From climate change to educational inequality, our most pressing problems require solutions that work at scale. Yet most organizations approach scaling with dangerous naivety, assuming what works small will naturally work large-a fundamental misunderstanding that wastes billions while truly scalable ideas languish unrecognized.
