PROGRESSIVISM, INDIVIDUALISM, AND THE PUBLIC<br />
INTELLECTUAL<br />
Frankly <strong>the</strong>re are a lot of ifs in this Theorem. Let me state it simply with an example. We<br />
will assume <strong>the</strong> following:<br />
1. There are N jurors.<br />
2. Each Juror makes an independent decision.<br />
3. Each Juror has identical information <strong>and</strong> is intellectually, morally, socially equal.<br />
There is no bias based on <strong>the</strong> facts presented.<br />
4. The evidence is such that each <strong>and</strong> every Juror will have a probability of p of selecting<br />
outcome A <strong>and</strong> a probability q (1-p) of selecting outcome B.<br />
5. There are an odd number of jurors.<br />
6. The Jurors vote in blind ballots <strong>and</strong> <strong>the</strong> selection is based upon <strong>the</strong> majority vote.<br />
Namely if we have 1 Juror, that Juror decides, if we have 3 Jurors, 2 decide <strong>and</strong> so forth.<br />
Now consider <strong>the</strong> case of 1 <strong>and</strong> 3 Jurors.<br />
One Juror:<br />
P[A]=p<br />
P[B]=1-p<br />
Three Jurors:<br />
P[A]=p 6 p<br />
3<br />
PB [ ] (1 p)<br />
3 2<br />
Clearly as N gets bigger <strong>the</strong> probability of B goes to zero <strong>and</strong> A goes to 1.<br />
However. recent work has shown that <strong>the</strong>re are substantial conflicts <strong>and</strong> inconsistencies.<br />
Dietrich has shown 173 :<br />
"that: (i) whe<strong>the</strong>r a premise is justified depends on <strong>the</strong> notion of probability considered;<br />
(ii) no such notion renders both premises simultaneously justified."<br />
Dietrich continues:<br />
Let me start by sketching a tempting but sloppy argument that seems to support <strong>the</strong> CJT.s<br />
two premises, <strong>and</strong> hence its striking conclusion. Consider for instance a group of judges<br />
