First we look at the people from this pool who our methods rank higher than Pantheon. By definition, all of these people will be highly regarded by both of our rankings. It is clear that we favor American and British leaders higher than they do, because we analyze only the English Wikipedia :
860 907 47 Woodrow Wilson U.S. President

Still, these are figures who are generally quite familiar to me: I've heard of all of them, although I would not be confident in my ability to tell one Alexander from the other. By contrast, there are several figures among the ones they rank much higher than we do who I could not place, or place as celebrities more than historical figures:

This roster makes clear the differences in our models for aging historical reputations. About half of these historically-overvalued people are relatively minor figures from ancient times: short-lived Emperors and second-tier philosophers/poets/artists. Many of the rest are contemporary celebrities who don't really belong in anyone's top thousand historical figures, like porn star Jenna Jameson.
There are also a few international artists of real stature (including Orhan Pamuk, Milan Kundera, and Pedro Almodvar) who might be undervalued by the English Wikipedia relative to international editions. Still, I think our rankings place them in the right order of magnitude.
