Bridge: “Wall Street in Miniature?”

Bear Stearns CEO Jimmy Cayne was a whizz at bridge. So was Bear-Stearns co-president Warren Spector. In The New Yorker, Malcolm Gladwell muses on how bridge may have contributed to their undoing.

It makes sense that there should be an affinity between bridge and the business of Wall Street. Bridge is a contest between teams, each of which competes over a “contract”—how many tricks they think they can win in a given hand. Winning requires knowledge of the cards, an accurate sense of probabilities, steely nerves, and the ability to assess an opponent’s psychology. Bridge is Wall Street in miniature, and the reason the light bulb went on when Greenberg looked at Cayne, and Cayne looked at Spector, is surely that they assumed that bridge skills could be transferred to the trading floor—that being good at the game version of Wall Street was a reasonable proxy for being good at the real-life version of Wall Street.

It isn’t, however. In bridge, there is such a thing as expertise unencumbered by bias. That’s because, as the psychologist Gideon Keren points out, bridge involves “related items with continuous feedback.” It has rules and boundaries and situations that repeat themselves and clear patterns that develop—and when a player makes a mistake of overconfidence he or she learns of the consequences of that mistake almost immediately. In other words, it’s a game. But running an investment bank is not, in this sense, a game: it is not a closed world with a limited set of possibilities.
