标题： Fast decisions reflect biases, slow decisions do not

摘要： 决策通常由异质性个体组成的群体做出，每个个体具有不同的初始偏见和不同质量的信息。 我们表明，在独立的大型代理人组中积累证据时，首先做出决定的是那些初始偏见最强的代理人。 无论事实如何，他们的决策都与他们的初始偏见一致。 相比之下，最后做出决定的代理人在做决定时就像他们最初没有偏见一样，因此做出了更好的选择。 我们在大群体极限下获得了渐近表达式，量化了代理人的初始倾向如何影响早期决策。 我们的分析表明，偏见、信息质量和决策顺序以非平凡的方式相互作用，从而决定了群体决策的可靠性。 显示英文摘要

摘要： Decisions are often made by heterogeneous groups of individuals, each with distinct initial biases and access to information of different quality. We show that in large groups of independent agents who accumulate evidence the first to decide are those with the strongest initial biases. Their decisions align with their initial bias, regardless of the underlying truth. In contrast, agents who decide last make decisions as if they were initially unbiased, and hence make better choices. We obtain asymptotic expressions in the large population limit that quantify how agents' initial inclinations shape early decisions. Our analysis shows how bias, information quality, and decision order interact in non-trivial ways to determine the reliability of decisions in a group.
