It depends on how quick. There was a book written called "Blink", which studied the human decision making process as it relates to time. The book's author found that decisions that took about 10 to 15 minutes to think about resulted in the right answer a surprising amount of the time. In fact, the decisions made in this time were right more of the time than those decisions made over days, weeks and even months. However, once you consider decision made in the time of seconds (10 seconds being an example), then the decisions made were usually wrong - sometimes disastrously so. So in this case a somewhat quick decision is good - a decision made in an instant is usually bad.
