Bias among Holy Writers vis-a-vis WAR for the HOF
If we treat WAR as the perfect way to capture the career value of a player, what else does a Holy Writer look for?
In all, the empirical analysis shows the following:
1) HoF voters undervalue walks (p-value .001)
2) HoF voters overvalue batting average (p-value .001)
3) HoF voters overvalue longer careers (p-value .001)
4) HoF voters undervalue starting pitchers (p-value .001)
5) HoF voters overvalue relief pitchers (p-value .001) though this bias seems to be decreasing
6) HoF voters overvalue Wins and Losses for pitchers (p-value .003)
7) HoF voters undervalue players at defensive positions (p-value .005)
8) HoF voters overvalue homeruns/RBI (p-value .06)
Great work to Sky.


Interesting ... I wonder what the rest of us overvalue? More important, what SHOULD we value in addition to WAR? Or should we use WAR only, regardless?
Suppose two guys have the same WAR, but one of them is also the best base stealer in history (the value of which is included in WAR). Should we give that player extra consideration because he’s the best ever?
I think I would. I’m willing to be convinced I shouldn’t.
