Clusters of JusticesHow do we go from a chart showing pairs of Justices to something reflecting relationships across groups of Justices?Here’s the approach:!I assigned a distance value to each pair of Justices, and then used an algorithm to flatten those distances into a two-dimensional graph.(1) For each decision, assign a “1”, “-1”, “0” to each Justice(2) Put all that into a matrix, and then add up the total agreement/disagreement between each pair of Justices(3) Divide each pair’s total by the number of votes that those!Justices actually shared (after recusals, departures, etc.)(4) Convert that into a distance measure for each pair, in n-dimensional space (Euclidean distance)(5) Use “MDS” to scale that down to 2 dimensions, and plot

*There is not yet enough data to plot Justice Brown.
Data fromMay 2012
