Eagles’ Carson Wentz Shows That If You’re Bad, Be $32 Million Bad

By almost any measure you choose, Philadelphia Eagles quarterback Carson Wentz has performed poorly this year, ranking at or near the league’s bottom in everything from inaccurate throwing to sacks and fumbles.

It’s a performance that would be inept enough to get many quarterbacks benched, which raises the question of why the team is sticking with Wentz. One reason has all the hallmarks of the sunk cost fallacy, the psychological quirk that corporate executives and investors alike frequently trip over in making decisions. You’ve spent a lot of time and money on something and you’re not about to give up on it.
