Building on the foundational idea of disruption index, w/ @skojaku.bsky.social & @yyahn.bsky.social we developed an embedding-based metric that preserves the core intuition while producing stable scores across simultaneous discoveries. 4/7

Some findings: - High-scoring papers on our metric are significantly more likely to be Nobel Prize-winning papers - Papers where our metric and the disruption index diverge most kept turning out to be simultaneous discoveries — Higgs mechanism, reverse transcriptase, asymptotic freedom, ... 5/7

We flipped this around to systematically detect simultaneous discoveries across science, finding about 18,000 potential pairs. Manual checks on a sample of highly cited pairs confirmed about 80% were genuine. 6/7

The disruption index is a beautifully simple idea: if a paper is disruptive, future work cites it but stops citing its references. The stream of knowledge has bent. But because it relies on local citation topology, simultaneous discoveries can throw it off. 2/7

The Higgs mechanism is a perfect example. Three teams, same discovery — yet the disruption index gives one paper a top 2.8% score while the others fall in the bottom 0.1% and 0.04%. 3/7

The Higgs mechanism was proposed in 1964 by three independent teams. But here is the puzzle🤔: the "disruption index" says Higgs's paper is among the least disruptive ever. So what is going on? In our new paper, just out in #ScienceAdvances, we take up this puzzle: doi.org/10.1126/scia... 👇 1/7

A new bibliometric index aims to do a better job of identifying whether a paper is a breakthrough by looking at both the papers it cites and the papers that cite it.
