When Deliberation Isn’t Smart

Cooperation is essential for successful organizations. But cooperating often requires people to put others’ welfare ahead of their own. In this post, we discuss recent research on cooperation that applies the “Thinking, fast and slow” logic of intuition versus deliberation. We explain why people sometimes (but not always) cooperate in situations where it’s not in their self-interest to do so, and show how properly designed policies can build “habits of virtue” that create a culture of cooperation. TL;DR summary: intuition favors behaviors that are typically optimal, so institutions that make cooperation typically advantageous lead people to adopt cooperation as their intuitive default; this default then “spills over” into settings where it’s not actually individually advantageous to cooperate.

Life is full of opportunities to make personal sacrifices on behalf others, and we often rise to the occasion. We do favors for co-workers and friends, give money to charity, donate blood, and engage in a host of other cooperative endeavors. Sometimes, these nice deeds are reciprocated (like when we help out a friend, and she helps us with something in return). Other times, however, we pay a cost and get little in return (like when we give money to a homeless person whom we’ll never encounter again).

Although you might not realize it, nowhere is the importance of cooperation more apparent than in the workplace. If your boss is watching you, you’d probably be wise to be a team player and cooperate with your co-workers, since doing so will enhance your reputation and might even get you a promotion down the road. In other instances, though, you might get no recognition from, say, helping out a fellow employee who needs assistance meeting a deadline, or who calls out sick.

Game Theory Analysis Shows How Evolution Favors Cooperation’s Collapse

Last year, University of Pennsylvania researchers Alexander J. Stewart and Joshua B. Plotkin published a mathematical explanation for why cooperation and generosity have evolved in nature. Using the classical game theory match-up known as the Prisoner’s Dilemma, they found that generous strategies were the only ones that could persist and succeed in a multi-player, iterated version of the game over the long term.

But now they’ve come out with a somewhat less rosy view of evolution. With a new analysis of the Prisoner’s Dilemma played in a large, evolving population, they found that adding more flexibility to the game can allow selfish strategies to be more successful. The work paints a dimmer but likely more realistic view of how cooperation and selfishness balance one another in nature.

“It’s a somewhat depressing evolutionary outcome, but it makes intuitive sense,” said Plotkin, a professor in Penn’s Department of Biology in the School of Arts & Sciences, who coauthored the study with Stewart, a postdoctoral researcher in his lab. “We had a nice picture of how evolution can promote cooperation even amongst self-interested agents and indeed it sometimes can, but, when we allow mutations that change the nature of the game, there is a runaway evolutionary process, and suddenly defection becomes the more robust outcome.”
