  2. First Annual CMC Tournament Computer-Mediated Communication — Cheshire & Fiore

  3. Types of dilemmas • Different games make different use of the payouts • T>R>P>S Prisoner's DilemmaT>R>S>P ChickenT>P>R>S DeadlockR>T>P>S Stag Hunt Standard PD game T>R>P>S Computer-Mediated Communication — Cheshire & Fiore

  4. The Evolution of Cooperation • Axelrod’s famous tournament allowed individuals to submit any strategy. • All strategies played each other in the tournament. • The winner was one of the shortest submissions, about 4 lines of code. Computer-Mediated Communication — Cheshire & Fiore

  5. The Simple Effectiveness of the Tit-for-Tat Strategy • Tit-for-Tat: begin with ‘cooperate’ and then do whatever the opponent did on the last turn. Computer-Mediated Communication — Cheshire & Fiore

  6. Lessons from Tit-for-Tat • Be nice • It starts by cooperating. All top-scoring strategies do this. • Be forgiving • It quickly and happily returns to cooperation without holding a grudge. • Be able to retaliate • It never allows defection to go unpunished. • Be clear • It is predictable and easy to understand. It pays to be predictable in non-zero sum games. Computer-Mediated Communication — Cheshire & Fiore

  7. Public Good Is Tit-for-Tat Always the Answer? • N-person PD • 2-person repeated PD Computer-Mediated Communication — Cheshire & Fiore

  8. Where does this apply in our world? Wherever we find mixed-motive situations and collective action… Standards Wars Online Tagging Systems (folksonomies), Collaborative Editing Systems Del.ic.ious Computer-Mediated Communication — Cheshire & Fiore

  9. Public goods on the Internet Smaller groups tend to have a better chance of producing a public good (Olson 1965) Why? • More benefits for each person • Larger impact of any single contribution • Generally, lower costs of organization Computer-Mediated Communication — Cheshire & Fiore
