rewardrather

Rewardrather is a term used in discussions of decision making and artificial intelligence to describe a tendency or strategy that prioritizes immediate reward over future payoff. The word is a blend of reward and rather, suggesting a preference for the reward presented at hand rather than contingent future gains. It can describe a behavior, a policy in artificial agents, or a heuristic used by people when choosing between options with different short- and long-term consequences.

Its usage overlaps with but is distinct from concepts such as myopic decision making, present bias, or greedy algorithms. Rewardrather emphasizes the source of preference (the reward signal), rather than the computational method, though in practice it often manifests as a short-sighted policy in reinforcement learning.

In psychology and behavioral economics, rewardrather aligns with present bias and hyperbolic discounting, where immediate utilities are weighted more heavily than delayed ones, leading to suboptimal long-term outcomes.

In artificial intelligence, a rewardrather policy may maximize immediate reward at each step, potentially ignoring future rewards unless the system includes discount factors, exploration, or planning modules that account for long-term value.

Critics note that rewardrather can hinder long-term performance in dynamic environments, and remedies include shaping rewards, incorporating planning horizons, or using algorithms that balance exploration and exploitation.

Related concepts include greedy algorithms, myopic policies, hyperbolic discounting, present bias, and reinforcement learning.
