Dictator Game

An experimental protocol where one participant unilaterally splits an endowment with a powerless recipient — by stripping away every strategic lever, it forces any positive transfer onto the non-strategic ledger, so its lattice of single-bit variants decomposes the sources of pro-social behaviour.

Core Idea

The dictator game is a minimal experimental protocol in which one participant, the dictator, receives a fixed endowment and decides unilaterally how much to transfer to a powerless recipient who cannot accept, reject, or retaliate. Self-interested rationality predicts a transfer of zero; empirically, dictators give 20–30% on average, with a modal 50% split. Because all strategic structure is removed, any positive transfer must be attributed to non-strategic motives, and its variants isolate each one.

Scope of Application

Because the dictator game is a controlled protocol, it applies wherever its precondition can be set up — a participant given an endowment and unilateral allocation power over a powerless recipient.

  • Experimental economics — the home laboratory; one of the core paradigms, its allocation a portable dataset.
  • Behavioral game theory — an anchor for inequity-aversion and warm-glow utility models.
  • Cross-cultural anthropology — Henrich et al.'s fifteen small-scale societies testing norm variation.
  • Development economics — transfer protocols measuring social capital and intervention effects.
  • Neuroeconomics — allocations correlated with medial-prefrontal and temporoparietal activation.

Clarity

Naming the dictator game makes legible a distinction richer games entangle: strategic motives for giving (fear of punishment, anticipated reciprocity, reputation) versus non-strategic ones (altruism, inequity aversion, fairness norms, being observed). Removing every strategic lever forces any transfer onto the non-strategic ledger, which is what lets a researcher read the ultimatum game correctly. The recipient's powerlessness is not a limitation but the instrument's calibration, and the sharper question becomes which component of pro-sociality produced this transfer.

Manages Complexity

Observed giving is a snarl of co-acting causes, confounded in richer games. The dictator game tames it not by modeling the mixture but by supplying a baseline that zeroes out an entire class of strategic terms, so whatever remains is the non-strategic residue. The compression compounds because the paradigm is a lattice of single-bit contrasts — versus ultimatum (punishment), versus trust (reciprocity), versus double-blind (audience) — each isolating one additive component, reducing "what generates generosity?" to a few pairwise differences.

Abstract Reasoning

The paradigm licenses diagnostic reasoning (attributing residual giving to a non-strategic source by elimination, reading each treatment's shift as one component), interventionist reasoning (designing each variant as a controlled subtraction isolating one motive), boundary-drawing (separating strategic from non-strategic motives, treating powerlessness as calibration), and prediction (self-interest forecasts zero, robustly contradicted; each single-bit contrast forecasts which term it moves).

Knowledge Transfer

The dictator game is a measurement instrument, not a causal mechanism, so it transfers literally wherever its precondition holds — across experimental economics, development economics, anthropology, and neuroeconomics — the same instrument read by the same logic of controlled subtraction. The over-reading to guard against is treating its canonical number (20–30%, modal 50%) as a universal constant rather than a local mix of motives; only the lattice of contrasts licenses a component claim. The other-regard it reveals travels onward under fairness, altruism, reciprocity, and cooperation, not as "the dictator game."

Neighborhood in Abstraction Space

Dictator Game sits in a crowded region of the domain-specific corpus (36th percentile for distinctiveness): several abstractions share nearly its structure, so a description that fits it tends to fit its neighbors too.
