A Sharp Test of the Portability of Expertise
研究让专业人士完成一个逻辑相同但情境不同的任务，发现其表现大幅下降，说明专业技能更多依赖情境线索而非深层概念，迁移性有限。
To what extent does expertise depend on context? We observe professionals perform a task that is logically isomorphic to—but contextually distinct from—a familiar task in which they are skilled. We find that performance plummets when contextual cues disappear, suggesting that the expertise we observe on the familiar task is more heuristic than conceptual and does not travel far.
