Hypothesis
A brief mindfulness exercise or facial emotion recognition training would immediately improve empathic accuracy — how well people infer others' emotions.
What failed
Across three conditions of 23 psychology students each (mindfulness, emotion-recognition training, neutral lecture control), there was no significant overall difference in empathic accuracy, so neither target intervention had an effect.
Broken assumption
Empathic accuracy is acutely malleable by a single brief intervention.
Why
The paper reports only one qualification: among participants with limited understanding of the task's Dutch-language material, accuracy was better after emotion-recognition training than control. The authors list a small convenience sample, a mindfulness lecture as control, no baseline measure and no formal language assessment as limitations.
