I know little of human psychology, I’ll admit it. But I do know enough to say this one thing rather definitively: Cognitive biases will mess you up.
To wit, Jose Iglesias, among Reds with at least 40 plate appearances, sits second in batting average, fourth in on-base percentage, and sixth (!) in slugging. Jose Iglesias, light-hitting defensive wizard brought in on a minor-league deal, has out slugged both Yasiel Puig and Joey Votto through the first quarter of the season.
Now obviously, a hitter’s slashline doesn’t paint the whole portrait of their season. Iglesias is seventh in wRC+ among the same group and eighth in ISO.
