Definition
Moral Plasticity is the capacity of human moral values and ethical standards to change, expand, or adapt over time in response to new information, technological shifts, or cultural evolution. It acknowledges that what is considered “good” or “just” today may be seen as barbaric or limited in the future.
Why It Matters
Humans are remarkably good at justifying bad behavior. Recognizing moral plasticity—how easily our ethics shift based on environment—is the first step in designing ‘choice architectures’ that nudge us toward our better selves rather than our most selfish ones.
Core Concepts
- Moral Progress: The idea that humanity’s moral circle has expanded over time (e.g., from tribe to nation to all of humanity, and potentially to non-human animals and future generations).
- Technological Drivers: New technologies often create new moral dilemmas or render old ones obsolete (e.g., the birth control pill changed sexual ethics; the internet changed privacy ethics).
- Value Drift: The risk that future generations’ values might drift in a direction we would find horrifying, or the opportunity for them to find moral truths we are currently blind to.
- Malleability of Culture: Moral standards are often “path-dependent”—early cultural choices can lock in certain moral directions for centuries.
