  "account": "Choosing among actions with varying future consequences is a common challenge faced in everyday problems. Despite the computational difficulty of fully evaluating these consequences, the human brain can efficiently solve such complex problems. The authors of this paper propose that this ability is underpinned by a principle inspired by Bayesian accounts of perception and sensorimotor control. According to this principle, evidence from effortful forward planning is integrated with task-specific preferences, which function similarly to priors, and are weighted by the uncertainty of these preferences.\n\nTo validate this hypothesis, the researchers conducted a sequential decision-making task featuring a large state space. Their analysis revealed that participants' deviations from optimal forward planning are best explained by task-specific preferences rather than by unsystematic errors, recent action-history effects, or offer-context biases. Furthermore, the impact of forward planning on participants' responses varied depending on preference uncertainty. This variation was observed in both choice behavior and reaction times, indicating that preferences play a crucial role in decision-making.\n\nInterestingly, the preferences did not emerge arbitrarily but instead supported above-stochastic performance even without the aid of forward planning. The authors conclude that these task-specific preferences provide an inexpensive, quickly accessible first-pass solution to complex decision-making tasks. When the uncertainty surrounding these preferences increases, forward planning steps in to refine the initial guidance, resulting in more optimal decision-making. Overall, these findings support a Bayesian-inspired interpretation of decision-making, wherein costly forward planning is integrated with task-dependent priors or preferences to guide human behavior efficiently.",
  "summary": "Everyday problems often require choosing among actions with different future consequences, even though fully evaluating those consequences is often computationally infeasible. The human brain is remarkable in its ability to solve such complex problems efficiently. In this paper, we hypothesize that this capacity arises from a principle inspired by Bayesian accounts of perception and sensorimotor…",
