A friend of mine, a former air traffic controller, recounted to me the other day an incident with one of the last trainees she was assigned before she retired.
She gave the girl a scenario. Two planes are flying at seven thousand feet in clear midday skies. They are flying at a steady speed and their trajectory will have them crash into each other in approximately 30 minutes. There are no other aircraft in their air space and none expected to join them. What do you do? The young woman she was training said nothing. My friend then said, you now have 25 minutes, what do you do? The young woman said nothing. 20 minutes. 15 minutes. 10 minutes.
My friend looked at this young woman and asked her what was she waiting for and the young woman replied, she didn't know what was the best answer.
In really life, there is more often than not no best answer, but there can be thousands of satisfactory answers. Have one plane fly higher. Have one plane fly lower. Have one plane speed up, have one plane slow down. Change the angle of either plane or both. And so on. This need for a BEST answer, I think, comes from an over emphasis of objective, multiple choice testing. We are educating a generation of people who know only how to look at a choice of stated answers and then and only then can they decipher which among the choices given is the BEST answer.
Life is not a fill in the bubble test and you need to be able to think about situations without reading A,B,C,D, and E because life doesn't provide lettered choices.
