We experimentally explore the effects of time limitation on decision making. Under different time allowance conditions,

subjects are presented with a queueing situation and asked to join one of the two given queues. The results can be grouped

under two main categories. The first one concerns the factors driving decisions in a queueing system. Only some subjects

behave consistently with rationality principles and use the relevant information efficiently. The rest of the subjects seem to

adopt a simpler strategy that does not incorporate some information into their decision. The second category is related to the

effects of time limitation on decision performance. A substantial proportion of the population is not affected by time limitations

and shows consistent behavior throughout the treatments. On the other hand, some subjects’ performance is impaired by time

limitations. More importantly, this impairment is not due to the stringency of the limitation but rather to being exposed to a

time constraint.
