当摩擦有益：交易确认提高区块链交互中的决策质量
When Friction Helps: Transaction Confirmation Improves Decision Quality in Blockchain Interactions
AI总结：
研究发现交易确认在区块链交互中能提升决策质量，尽管用户偏好无摩擦模式，但确认有助于自我纠正，表明需在交互流畅性与决策质量间取得平衡。
摘要：
在区块链应用中，交易确认通常被视为需要最小化或去除的可用性摩擦。然而，确认也标志着犹豫与不可逆承诺之间的边界，表明它可能在人类决策中发挥功能性作用。为了研究这种张力，我们进行了一项实验，使用基于区块链的连接四游戏，两种交互模式仅在授权流程上有所不同：手动钱包确认（确认模式）与自动授权委托（无摩擦模式）。尽管参与者更喜欢无摩擦模式并认为表现更好（N=109），但在平衡部署中没有确认的情况下客观表现更差（第二波：胜率-11.8%，p=0.044；移动质量-0.051，p=0.022）。分析取消提交表明确认可以启用预提交自我纠正（N=66，p=0.005）。这些发现表明，交易确认可以作为一种具有认知意义的检查点，而不是单纯的可用性摩擦，突显了在不可逆的区块链交互中交互流畅性与决策质量之间的权衡。
英文摘要：
In blockchain applications, transaction confirmation is often treated as usability friction to be minimized or removed. However, confirmation also marks the boundary between deliberation and irreversible commitment, suggesting it may play a functional role in human decision-making. To investigate this tension, we conducted an experiment using a blockchain-based Connect Four game with two interaction modes differing only in authorization flow: manual wallet confirmation (Confirmation Mode) versus auto-authorized delegation (Frictionless Mode). Although participants preferred Frictionless Mode and perceived better performance (N=109), objective performance was worse without confirmation in a counterbalanced deployment (Wave 2: win rate -11.8%, p=0.044; move quality -0.051, p=0.022). Analysis of canceled submissions suggests confirmation can enable pre-submission self-correction (N=66, p=0.005). These findings suggest that transaction confirmation can function as a cognitively meaningful checkpoint rather than mere usability friction, highlighting a trade-off between interaction smoothness and decision quality in irreversible blockchain interactions.
