The photograph attached was taken by the crew on board the Columbia during its last mission, on a cloudless day. The picture is of Europe and Africa when the sun is setting.
Half of the picture is in night. The bright dots you see are the cities’ lights.
The top part of Africa is the Sahara Desert .
Note that the lights are already on in Holland , Paris , and Barcelona,
and that’s it’s still daylight in Dublin , London , Lisbon , and Madrid .
The sun is still shining on the Strait of Gibraltar . The Mediterranean Sea is
already in darkness.
In the middle of the Atlantic Ocean you can see the Azores Islands;
below them to the right are the Madeira Islands ; a bit below are the
Canary Islands; and further South, close to the farthest western point
of Africa , are the Cape Verde Islands.
ordinary intuition is just a feeling, a gut instinct. expert intuition is snap judgments, when you instantly recognize something familiar, the way a tennis pro knows where the ball will go from the arc and speed of the opponent’s racket… the third kind, strategic intuition, is not a vague feeling, like ordinary intuition. strategic intuition is a clear thought… that flash of insight you had last night might solve a problem that’s been on your mind for a month.
expert intuition is always fast, and it only works in familiar situations. strategic intuition is always slow, and it works for new situations, which is when you need your best ideas.
this difference is crucial, because expert intuition can be the enemy of strategic intuition. as you get better at your job, you recognize patterns that let you solve similar problems faster and faster. that’s expert intuition at work. in new situations your brain takes much longer to make enough new connections to find a good answer. a flash of insight happens in only a moment, but it may take weeks for that moment to come. you can’t rush it. but your expert intuition might see something familiar and make a snap judgment too soon. the discipline of strategic intuition requires you recognize when a situation is new and turn off your expert intuition. you must disconnect the old dots, to let new ones connect on their own.
