A <a href="https://en.wikipedia.org/wiki/heatmap" class="extiw" title="w:heatmap">heatmap</a> of signatures to the <a href="https://en.wikipedia.org/wiki/Access2Research" class="extiw" title="w:Access2Research">Access2Research</a> petition. The shades of pale blue are somewhere below or about the national average. The lowest score was 37.3 (Mississippi) and the closest to average score was 50.3 (Nebraska). If a state is solid blue, then it is on-par with the rest of the country.  Moving up the color scheme, each solid color is one more standard deviation above the average (i.e., Green is +1SD, Yellow is +2SD, etc.).  The scale topped off at 88.9 (Massachusetts).
