is there a term for a situation where a person is given an ostensibly equal choice between two alternatives but if the person is unable or unwilling to make a decision, the decision defaults to one or the other? a simple example would be if someone were at a train station, trying to decide whether to hop on and head to a destination or remain in town. if the train leaves before the person has made the choice, then the decision has been effected for him without any proactive effort on his part.

the opposite would be a choice such as whether to order one meal or another, and hesitating so long as to cause the waiter to slip away without anything having been ordered; in this case there is no forced decision.

i'm not speaking of hobson's choice; my query doesn't necessarily refer only to when neither choice is palatable, although it could encompass that scenario as well.
