The legal system changed gradually and remarkably effectively, case by case, like water finding new paths through old stone. It did not announce itself with a historic ruling or a dramatic press conference, and practitioners did not realize at one point that the ground had changed beneath them.
Long regarded as a meticulous, precedent-bound field, tort law began to change over the past few decades, reacting to collective outrage, industrial harm, and social pressure with a flexibility that felt remarkably more like an adaptive network than a strict code.

With asbestos, tobacco, and environmental contamination cases swarming like a swarm of bees around corporate defendants, mass tort litigation served as the catalyst. While each claim was minor on its own, taken together, they were sufficiently potent to change the allocation and pricing of accountability.
Courts made it possible for plaintiffs to seek remedies that would have been economically unfeasible a generation ago by aggregating harm; this change proved especially creative in elevating voices that were previously written off as isolated or unfortunate.
As judges reexamined decades-old policy language and interpreted ambiguous clauses in ways that were significantly better for claimants and extremely unsettling for insurers, insurance law—often regarded as dry and procedural—was almost unintentionally drawn into the change.
Long-latent injuries and environmental cleanup were suddenly covered by policies designed for unexpected accidents, leading to results that felt much quicker and more comprehensive than insurers’ actuarial models had ever predicted.
The real shift was conceptual, redefining what insurance was supposed to do in a society that was becoming more conscious of collective and delayed harm, even as premiums increased, exclusions multiplied, and risk assessment changed.
Because scholars, judges, and practitioners largely assumed continuity and thought that liability would expand gradually and predictably, if at all, this period is instructive not only because of the magnitude of change but also because there was no prediction.
Kenneth S. Abraham claims that three significant developments came as a surprise: the emergence of mass torts, the expansion of insurance coverage they led to, and the sudden stop in liability growth that ensued after decades of gradual expansion.
As courts that had previously pushed doctrinal boundaries became more circumspect in response to worries about overreach, economic impact, and institutional legitimacy, the last change—the slowdown—proved to be equally significant.
After reading about that pause, I was somewhat surprised to discover how automatically I had believed that legal expansion was cyclical rather than permanent.
This pattern reveals a more profound reality about legal systems: they are remarkably resilient but not very adept at self-prediction, functioning more like weather patterns than engineering blueprints.
Prediction fails in part because incentives reward explanation far more than foresight, and in part because legal change is decentralized, with thousands of judges rendering narrow decisions that only later reveal a broader direction.
There is also a human component, as judges modify doctrine in ways that seem incredibly dependable at the time but unpredictable over time in response to cultural context, public opinion, and perceived fairness.
Courts dealing with polluted sites used historical insurance policies to interpret ambiguity against insurers, resulting in outcomes that were surprisingly inexpensive for cleanup efforts but extremely expensive for carriers. Environmental liability serves as a clear example of this.
The outcomes were especially helpful from a societal point of view, hastening compensation and remediation, but they also made the industry face long-ignored externalities.
Abraham’s work is compelling because it frames these changes as humility lessons rather than just mistakes or victories, arguing that legal actors need to embrace uncertainty as a structural element rather than an exception.
He contends that legal forecasting can become more highly efficient—not flawless, but better able to foresee stress points—by utilizing interdisciplinary tools—economics, political analysis, and behavioral insight.
Institutional memory is also important because it can be a very powerful tool for reducing overconfidence and promoting flexible thinking.
The temptation to believe in accurate forecasting has returned, stronger and more alluring, as AI tools are now used in legal practice, simplifying research, predicting results, and coordinating tasks like a disciplined swarm.
However, the previous revolution warns us to exercise caution, reminding us that human-made systems are still incredibly adaptable and obstinately resistant to precise forecasting.
The positive conclusion is that awareness has significantly increased, allowing for more open discussions about risk, accountability, and the boundaries of expertise—not that foresight is pointless.
Legal change seldom happens overtly, but if we are aware of its subtler cues, we have a better chance of reacting intelligently rather than hastily when the next change eventually materializes.
