Hypothesis
People judge purity violations with less regard for intent than harm violations because strange purity scenarios distract attention; so people with better attention, measured by the Attention Network Task, would not show this difference.
What failed
Attentional efficiency did not moderate the effect. People with high and low attentional efficiency showed the same reduced weight of innocent intent for purity violations.
Broken assumption
The weaker role of intent in purity judgments comes from people failing to attend to the intent information.
Why
The result fits the view that harm and purity judgments come from separate moral systems, not from a failure to notice the intent information.
