This article examines the relation of empathy and rational judgment. When people observe a conflict most are quick to side with one of the parties. Once a side has been taken, empathy with that party further solidifies this choice. Hence, it will be suggested that empathy is not neutral to judgment and rational decision-making. This does not mean, however, that the one who empathizes will necessarily have made the best choice.

AbstractIn a dynamic world, it is essential to decide when to leave an exploited resource. Such patch-leaving decisions involve balancing the cost of moving against the gain expected from the alternative patch. This contrasts with value-guided decisions that typically involve maximizing reward by selecting the current best option. Patterns of neuronal activity pertaining to patch-leaving decisions have been reported in dorsal anterior cingulate cortex (dACC), whereas competition via mutual inhibition in ventromedial prefrontal cortex (vmPFC) is thought to underlie value-guided choice. Here, we show that the balance between cortical excitation and inhibition (E/I balance), measured by the ratio of GABA and glutamate concentrations, plays a dissociable role for the two kinds of decisions. Patch-leaving decision behaviour relates to E/I balance in dACC. In contrast, value-guided decision-making relates to E/I balance in vmPFC. These results support mechanistic accounts of value-guided choice and provide evidence for a role of dACC E/I balance in patch-leaving decisions.

Evidential Decision Theory is a radical theory of rational decision-making. It recommends that instead of thinking about what your decisions *cause*, you should think about what they *reveal*. This Element explains in simple terms why thinking in this way makes a big difference, and argues that doing so makes for *better* decisions. An appendix gives an intuitive explanation of the measure-theoretic foundations of Evidential Decision Theory.

Policy and intelligence are intimately intertwined. Policymakers need intelligence to make decisions, while the intelligence community derives significance from its ability to provide policy makers with reliable information. In this symbiotic relationship, it is healthy for intelligence consumers to at times check and direct the work of intelligence producers. However, if undertaken maliciously, this checking mechanism manifests as top-down politicization. Here, leaders use intelligence post facto to legitimize their policies instead of using it to guide them, reversing the rational decision-making process. Certain factors may compel leaders to manipulate intelligence to reflect their policy preferences. This essay demonstrates how three distinct processes of top-down politicization can arise from ambiguous evidence, the psychology of intelligence consumers, and the nature of the leaders’ political positions and responsibilities. It then proceeds to argue that political leaders’ psychology is the most potent source of top-down politicization.
