The Art of the Soluble

Medawar, a Nobel-winning biologist, argues that good science is not about tackling the hardest problems but about choosing the ones that can actually be solved with the tools available — the art is in the picking.
The book collects essays on scientific method, Karl Popper, and the rhetoric of scientific writing, written with the literary polish of someone who took prose as seriously as biology.
For product direction the central insight transfers directly: shipping in most organisations is a function of choosing soluble problems and sequencing them, not of heroic effort on insoluble ones.
Medawar would have been an unusually sharp product director. A book to read slowly.
Central argument
Medawar's central argument is that scientific excellence lies not in the ambition to attack the grandest problems but in the judgment to select problems that are actually tractable given current methods and knowledge — what he calls 'the art of the soluble.' A scientist who consistently picks well-scoped, solvable problems produces more knowledge than one who heroically charges at questions that cannot yet be answered. The essays extend this into scientific epistemology, engaging Popper's falsificationism and dissecting the dishonest retrospective tidiness of formal scientific papers, which present discovery as deduction rather than the messy, intuition-driven process it actually is.
Critique
Medawar's framework implicitly privileges incremental, methodologically conservative science — the kind that yields to existing tools — and sits in tension with the history of breakthroughs that required inventing new tools precisely because the problem seemed intractable by current means. A thoughtful reader might ask how one distinguishes, in advance, a genuinely insoluble problem from one that merely lacks the right instrument not yet conceived; the 'art' Medawar describes may be less a learnable skill than a retrospective label applied to the judgments that happened to pay off. The essay form also means the argument is never fully systematised, leaving the core claim more as cultivated sensibility than operational principle.
Why it matters for product
For a product director, Medawar's thesis reframes the prioritisation problem entirely: the question is not which problems are most important but which are soluble given your current team capability, data quality, and organisational readiness — and those two rankings rarely coincide. This has direct consequences for roadmap design and discovery: pursuing a high-importance but currently insoluble problem (say, personalisation without instrumentation in place) burns cycles and erodes team credibility, whereas sequencing a soluble precursor problem first builds the capability stack that makes the harder problem tractable later. Medawar also offers a corrective to the performative ambition common in product strategy documents — the rhetoric of moonshots often masks the absence of the harder, less glamorous judgment about what can actually ship.
