How We Got to Now
6 memorable lines from How We Got to Now by Steven Johnson, each with the idea behind it.
“Innovation doesn't happen in a vacuum — it happens when the accumulated knowledge of centuries suddenly finds the missing piece.”
Steven Johnson's central argument: the 'eureka moment' is a myth. Most innovations are the result of long accumulation, slow convergence, and lucky adjacency.
“The most consequential ideas often emerge from the least expected places.”
Johnson on the history of sanitation: the public health revolution was driven not by doctors but by civil engineers, plumbers, and municipal reformers.
“Adjacent possible — the set of things that could exist at any moment is limited by what currently exists.”
Johnson on the constraint of innovation: the adjacent possible expands with every new discovery. The key is to see what the expansion has made available.
“Slow hunch — most significant discoveries are the result of intuitions that gestate for decades.”
Johnson on the timeline of innovation: Darwin carried the seeds of natural selection for 30 years before they bloomed. Most ideas need time.
“The network is the innovation — the idea is just the node.”
Johnson on how ideas form: individual genius is a myth. Ideas are emergent properties of networks, cultures, and accumulated hunches.
“Serendipity is not luck — it is the capacity to recognize the unexpected when it appears.”
Johnson on the prepared mind: the microwave was discovered by a scientist who noticed his chocolate bar had melted. Pasteur said luck favors the prepared mind.
