Closing our eyes affects our moral judgements

We experience emotion more intensely with our eyes closed

The simple act of closing our eyes has a significant effect on our moral judgement and behaviour. Eugene Caruso and Francesca Gino, who made the observation, think the effect has to do with mental simulation, whereby having our eyes closed causes us to simulate scenarios more vividly. In turn this triggers more intense emotion.

Throughout the study, Caruso and Gino concealed the true aim of the research from participants by telling them that part of the investigation was about judging the quality of head-phones. Participants were asked to listen to the rest of the study instructions through a pair of head-phones with a view to rating the sound quality. Crucially, half the participants were asked to listen to the different instructions and scenarios with their eyes closed – ostensibly to help their judgment of the sound quality – whilst the remainder listened with their eyes open.

Across the first three studies, the following effects were observed: participants with their eyes closed who heard a hypothetical scenario in which they deliberately over-estimated hours worked (so as to charge more) judged the act as more unethical than participants who heard the same scenario with their eyes open. Participants who heard the instructions for a simple financial game with their eyes closed subsequently shared money more fairly than participants who heard the instructions with their eyes open. And participants who listened to a hypothetical scenario with their eyes closed, in which nepotism and self-interest had biased a recruitment decision they’d made, judged that act as more unethical than did participants who heard the same scenario with their eyes open. Follow-up questions showed that the eyes-closed participants had visualised the scenario more vividly.

A fourth study was similar to the last except that some of the participants were given an explicit instruction to visualise the nepotism scenario as vividly as they could. This instruction led the eyes-open participants to judge the nepotistic act more harshly, similar to the eyes-closed participants. Overall, there was no evidence that the eyes-closed participants had simply paid more attention to the scenario than the eyes-open participants, but they did experience more negative, guilt-based emotion and it’s this effect that probably underlies the study’s central finding.

‘Although scholars from different fields have provided important insights in understanding why people commonly cross ethical boundaries, little research has examined potential solutions that are easily implementable,’ the researchers said. ‘Here we identified a simple strategy: closing one’s eyes, people are likely to simulate the decision they are facing more extensively and experience its emotional components more vividly. As a result … people may be more sensitive to the ethical nature of their own and others’ decisions, and perhaps behave more honestly as a result.’
