Do you have a moral dilemma? Don’t decide in a hurry
– instead, sleep on your decision and you’ll have a better answer in the
morning. So say researchers from the University of Washington, the University
of Oregon and John Hopkins University in America (mindfood.com,
January/February 2015).
University researchers maintain that if you have a
moral dilemma, a “big decision” then make sure you have a nap first. When
people don’t get enough sleep their moral compass decreases and they either
find it harder to solve moral dilemmas or their morality declines. The same
person can have different moral responses depending on their level of sleep.
It’s not just that different people have different responses to moral dilemmas,
but the same person can have lapses of morality.
Researchers found a link between sleep and morality.
Sleep seems to have an impact on people’s decision-making processes.
People in a laboratory study were randomly assigned a
specific amount of sleep, and then woken by the researchers. The control group
was assigned to have about seven hours of sleep. The treatment group was
assigned to have around 4.5 hours – these were the partially-deprived sleep
group. After their period of sleep researchers presented participants with
moral dilemma scenarios. Participants were shown ethical violations and asked
whether it was a moral issue or not.
Participants who were better rested were more able to
identify issues of morality – that is, whether a scenario presented a moral
dilemma to them. Sleep-deprived participants scored lower in moral awareness
than the control group – they could not identify moral dilemmas.
In a follow-up, new participants were asked to
monitor their own sleep. Participants then completed the same measure of moral
awareness as the first study.
When individuals were low in sleep, moral awareness
declined, and they scored low in moral dilemma problems. When the same
individuals had a full night’s sleep – of about seven hours – their morality
increased. They scored highly on moral dilemma problems. So often it may not be a
simple case of being influenced by other people – it may be just a case of not
enough sleep.
