The most widely endorsed reason productivity growth has faltered is that we are running out of good ideas. As this narrative has it, the many scientific and technology advances responsible for driving economic growth in the past were low-hanging fruit. Now the tree is more barren. Novel advances, we should expect, are harder to come by, and historical growth may thus be difficult to sustain. In the extreme, this may lead to the end of progress altogether.
This story began in 2020, with the publication of “Are Ideas Getting Harder to Find?,” by economists Nicholas Bloom and colleagues.1 Bloom et al. looked across many sectors, from agriculture to medicine to computing. In each field, productivity measures have grown at the same rate as before. This sounds like good news, except that the number of researchers in each of these fields has exploded. In other words, each researcher produces much less than they used to — something you might expect if ideas really are getting harder to find.
The progress studies movement and the metascience community have risen, in part, in response to this challenge. Both seek ways to rethink how we do research: by making our research institutions more efficient or by increasing science funding.
But there’s a growing body of evidence that suggests ideas are not, in fact, getting harder to find.
