Decoding Innovation: Can We Predict the Next Breakthrough?

"A new study combines complexity science and big data to reveal hidden patterns in how innovations, like vaccines, emerge and accelerate."


We often think of innovation as a forward march, but the path to groundbreaking discoveries is rarely a straight line. It's a messy process, full of dead ends, unexpected turns, and collaborations that span years. But what if we could understand the 'order' hidden within this complexity? What if we could identify the key steps that truly drive innovation forward?

A recent study is offering a new approach to the challenge, one that moves beyond simple timelines and delves into the intricate relationships between scientific advancements. By combining complexity science with the vast amounts of data available on vaccine development, researchers are uncovering the underlying patterns that govern how innovations actually happen.

This isn't just an academic exercise. Understanding the 'order of innovation' could revolutionize how we fund research, design innovation programs, and ultimately, accelerate the development of life-saving technologies.

Beyond the Timeline: Mapping the Innovation Network

Complex network representing scientific innovation over a DNA double helix.

The traditional way of looking at innovation is to chart events on a linear timeline. However, this approach struggles to capture the true essence of how innovations build upon each other. It also fails to identify the critical bottlenecks that slow down progress. Imagine a multi-step chemical reaction: the overall process can only move as fast as its slowest, rate-determining step. Similarly, the innovation process contains intermediary outputs, and it has bottlenecks whose catalysis could accelerate overall innovation progress.

To address this limitation, the study's authors propose a novel approach, the use of a multilayer directed acyclic graph (DAG). Think of a DAG as a map where each node represents a scientific or technological milestone—a research paper, a patent, a clinical trial—and the edges connecting the nodes show how one advancement builds upon another through citations. This network visually represents the flow of knowledge and influence, revealing the order in which innovations occur. It is helpful to know: a network (or graph) is a set of nodes, and pairs of nodes can be connected by an edge.
  • Nodes: Each node represents a single document which is one of four types: an innovation outcome represented by regulatory authorisation, a clinical trial, a patent, or an academic publication.
  • Edges: The edges, written as (u, v), are citations from one node u to another node v; citation networks have a sense of direction as (u, v) represents an entry listing document v in the bibliography of a document u, not the other way round.
  • DAG structure: The data gives networks where 0.07% of all edges are part of a cycle, for example, due to authors citing each others' paper during journal submission or mislabelling. This 0.07% is removed to to ensure reduce our the networks we analyse are always DAGs.
By analyzing the structure of this network, researchers can identify 'critical paths'—sequences of events that are most crucial for driving innovation forward. They can also pinpoint bottlenecks, areas where progress is slow or stagnant. This allows for a more nuanced understanding of the innovation process than a simple timeline could ever provide.

From Data to Action: Shaping the Future of Innovation

This new approach to understanding innovation is more than just a theoretical exercise. By revealing the hidden order within complex systems, it offers a powerful tool for policymakers, researchers, and industry leaders alike. Imagine being able to identify the most promising areas for research investment, anticipate potential bottlenecks, and accelerate the development of life-saving technologies. By studying the series of vaccine citation networks, we can discover many different things that will help build medical products quicker.
