      To avoid this problem, we surveyed scientists at leading institutions, asking them to do pairwise comparisons ranking Nobel prizewinning discoveries in their disciplines. Eg: discovery of neutron vs cosmic background radiation? Etc.

      We gathered 4,483 such comparisons. From this portfolio of questions we can back out progress in science (according to this metric) over the decades.

      Here's the results for chemistry, and for physiology or medicine, showing, perhaps, a slight improvement:pic.twitter.com/9SJKd4j4xt

      What's being plotted: the probability a discovery made in that decade is ranked above discoveries made in other decades.

      The kicker is: the amount we're investing in science has gone up enormously (think 10-100x) over the same time period, whether you look at $, number of scientists, or number of publicationspic.twitter.com/9gBu2FREw0

      Lots of disclaimers: this is just one metric, there's plenty of shortcomings of the metric. We're very aware of that and discuss this in the essay.https://www.theatlantic.com/science/archive/2018/11/diminishing-returns-science/575665/ …

      I appreciate the explicit acknowledgements of limitations of the article's metric. But shouldn't that give you pause in using such a strong title? Such a complex question such as this simply cannot be boiled down into looking at such a simple metric with so many possible biases.

      There are many measures considered (age, team size, the survey results, and, ancillary, productivity growth). And, of course, they're all being compared to input measures ($, number of scientists, number of papers). No matter which pair you consider, you see dim. rets.

      As is common in this kind of writing, we weren't directly consulted on the title or subtitle. But I think the title is reasonable. We're not _certain_. But we think the evidence is strong enough it should be seriously considered.

          Ah I see! Just concerned that people see titles like these (without reading the article) and use it as an argument against science, especially in a time/political environment where science is often being assaulted as useless (e.g., climate change research).

          I think it's perfectly fair and important to assess the ROI on scientific investments though, so I approve of the article itself (quite an interesting read)!
