Broadening the Training Set for Alignment
Coverage of lessw-blog
In a recent analysis, lessw-blog investigates how classic machine learning techniques for improving generalization can be specifically adapted to the challenge of AI alignment.
In a recent post, lessw-blog discusses a pragmatic approach to the AI safety problem: applying the standard machine learning practice of "broadening the training set" to ethical judgments and high-stakes decision-making. As AI systems advance toward general intelligence, the primary risk lies in their ability to generalize human values to situations that were never present in their training data. This post argues that rather than hoping models will correctly extrapolate safety protocols to novel scenarios, researchers should explicitly expand the training distribution to cover these edge cases.
The context for this discussion is the "alignment challenge," which the author frames fundamentally as a generalization problem. Neural networks are notoriously dependent on their training distributions. If a model is trained solely on mundane, low-stakes human interactions, there is no guarantee it will behave ethically when faced with the unprecedented capabilities of a superintelligence. The post proposes broadening the training set to include specific, high-stakes decision types that are currently absent, such as scenarios involving the evasion of human control, global governance decisions, and the model's own self-perception and goal-setting.
A critical constraint highlighted in the analysis is the necessity of consistency between alignment training and capability training. The author warns against alignment strategies that rely on "lying" to the model-feeding it simplified or false premises about the world to coerce safe behavior. If the broadened training set contradicts the model's accurate understanding of reality (derived from its capability training), the strategy risks backfiring. A highly intelligent system might recognize the inconsistency, leading to alignment failure. Therefore, any expanded dataset must be rigorously fact-based and consistent with the model's operational reality.
The post positions this approach not as a silver bullet, but as a necessary layer in a "hodge-podge" strategy. The author admits that broadening the training set does not resolve the problem of mesa-optimization-where a model might internally develop objectives distinct from its training goals. However, it argues that a robust safety profile will likely consist of multiple, overlapping strategies rather than a single theoretical breakthrough. By integrating broadened training sets with existing methods like Constitutional AI, developers can create a more resilient safety net.
Ultimately, this analysis serves as a call for empirical investigation. While the concept of broadening training sets is foundational to machine learning, its specific application to the domain of ethical judgment and existential risk remains under-explored. The post encourages the research community to move beyond theoretical debates and begin generating the datasets necessary to test this hypothesis.

Key Takeaways
- Alignment is fundamentally a generalization problem; models must apply values to contexts they haven't explicitly seen.
- Training sets should be explicitly broadened to include high-stakes scenarios like control evasion and global governance.
- Alignment data must be consistent with capability data; 'lying' to a model about reality to enforce safety is dangerous.
- This approach is part of a 'hodge-podge' defense strategy, acknowledging that no single fix solves all safety concerns.
- There is a critical need for empirical work to create and test these broadened ethical datasets.
