Years ago, Malcolm Gladwell wrote a book called "Blink," where he assembles evidence in support of the idea that sometimes we make better choices unconsciously, in the blink of an eye, than we do after careful consideration. "Great decision makers aren't those who process the most," he argued.

So, could that "blink" ethos be brought to radiology and reading mammograms?
