“Now let's consider the impact of sleep deprivation on our ability to distinguish right from wrong. A study of people in a raffle ticket competition found participants were more likely to cheat if they'd had as little as twenty-two minutes' less sleep than normal. Another study found we're less likely to search the internet for ethics-related queries the day we shift our clocks forward to daylight-saving time. Other studies found tired people are less likely to notice unethical behaviour in others, or even to recognise in the first place whether there is a moral or ethical question at stake.” SleepImpact Of Sleep Deprivation Book:On Sleep Source: On Sleep
