There are several effects of sleep deprivation indicating that it could have negative consequences. For example, sleep-deprived individuals are less flexible in changing plans and courses of action and are generally less able to deal with the unexpected. Moreover, sleep deprivation can have negative effects on motivation and learning in a group. However, there are possible ways in which sleep deprivation might not be a severe problem. For example, sleep-deprived people might compensate for deficits by using advice or by mutually monitoring group performance.
