Last week, we challenged readers to draw the outlines of all 50 states and Washington, D.C. from memory, and then graded each attempt using an algorithm to measure how closely each submission resembled the correct shape. Based on over 2 million submissions, we are now able to measure which states were the hardest and which were the easiest.
While some of the results were what we expected, other states were surprisingly confounding. As you might guess, the easiest state was Colorado, where 93% of participants scored at least a 'B' and usually an 'A' or 'A+'. (Colorado is almost a perfect rectangle when one uses the common map projection used in Web applications.)
