Influential studies on human thinking with the popular two-response paradigm typically ask participants to continuously alternate between intuitive (“fast”) and deliberate (“slow”) responding. One concern is that repeated deliberation in these studies will artificially boost the intuitive, “fast” reasoning performance. A recent alternative two-block paradigm therefore advised to present all fast trials in one block before the slow trials were presented. Here, we tested directly whether allowing people to repeatedly deliberate will boost their intuitive reasoning performance by manipulating the order of the fast and slow blocks. In each block, participants solved variants of the bat-and-ball problem. Maximum response time in fast blocks was 4 s and 25 s in the slow blocks. One group solved the fast trials before the slow trials, a second group solved the slow trials first, and a third mixed group alternated between slow and fast trials. Results showed that the order factor did not affect accuracy on the fast trials. This indicates that repeated deliberation does not boost people’s intuitive reasoning performance.

使用流行的双反应范式对人类思维进行的有影响力的研究通常要求参与者在直觉（“快速”）和故意（“慢”）反应之间不断交替。一种担忧是，这些研究中的反复审议会人为地提高直观、“快速”的推理能力。因此，最近的另一种两块范式建议在呈现慢速试验之前在一个块中呈现所有快速试验。在这里，我们直接测试了允许人们反复思考是否会通过操纵快慢块的顺序来提高他们的直觉推理性能。在每个模块中，参与者解决了蝙蝠和球问题的变体。快速块中的最大响应时间为 4 秒，慢速块中为 25 秒。一组在慢速试验之前解决了快速试验，第二组首先解决慢速试验，第三混合组在慢速试验和快速试验之间交替进行。结果表明，顺序因子不影响快速试验的准确性。这表明反复推敲并不能提高人们的直觉推理能力。
