The seventh-generation test for decisions

Before a major choice, ask how it will affect people seven generations from now.

Why it works

Decision framing powerfully shapes what alternatives are considered and what trade-offs become visible. The seventh-generation heuristic (drawn from Haudenosaunee tradition) forces the decision-maker to project consequences forward in time, activating consideration of slow-accumulating effects that short-horizon framing systematically ignores.

How to do it

1. When facing a significant decision (career, community, environmental), write the question: "What are the seventh-generation consequences of each option?"
2. List the three most plausible long-run effects of each alternative.
3. Identify which option you would endorse if you had to justify it to a descendant living with those consequences.
4. Weight the seventh-generation view alongside other considerations — it does not override, it augments.

Evidence

Extending decision time horizons has been shown to reduce hyperbolic discounting and improve the quality of choices for long-run outcomes; the seventh-generation framing specifically has not been studied experimentally. (mechanistic)

Direct experimental evidence for this specific framing is absent; the mechanism rests on time-perspective and temporal discounting research more broadly.

Common mistake

Using the test as a paralysis device rather than an additional lens — it supplements short-term analysis, it does not require certainty about 200-year consequences.
