Scientific bottlenecks form precisely where prior methods and heuristics stop applying, since researchers already exploit whatever has worked before — so genuine breakthroughs require many people pursuing different unproven approaches rather than a single reliable process.

Nielsen argues there's no universal 'crank to turn' for discovery — progress gets stuck exactly where old heuristics fail, and escaping that requires many parallel, unguaranteed attempts, with bigger bottlenecks yielding bigger eventual triumphs. ✦ AI generated

If you're attempting to reduce science to a process, you're attempting to reduce it to something where there is just a method which you can apply, and you turn the crank and out pops insight. You can do a certain amount of that, but you're going to get bottlenecked at the places where your existing method doesn't apply.
