  • To find a good strategy to use in such situations, I invited experts in game theory to submit programs for a computer Prisoner’s Dilemma tournament – much like a computer chess tournament.
  • the winner was the simplest of all candidates sub- mitted. This was a strategy of simple reciprocity which cooperates on the first move and then does whatever the other player did on the previous move. Using an American colloquial phrase, this strategy was named Tit for Tat.
  • face of an uncalled-for defection by the other, forgiveness after responding to a provocation, and clarity of behavior so that the other player can recognize and adapt to your pattern of action.

      These conditions are core.
  • data from these tournaments reveals four properties which tend to make a strategy successful: avoidance of unnecessary con- flict by cooperating as long as the other player does, provocability in the
  • What made this mutual restraint possible was the static nature of trench warfare, where the same small units faced each other for extended periods of time. The soldiers of these opposing small units actually violated orders from their own high commands in order to achieve tacit cooperation with each other
  • the individuals involved do not have to be rational: The evolutionary process allows successful strategies to thrive, even if the players do not know why or how. Nor do they have to exchange messages or commit- ments: They do not need words, because their deeds speak for them. Likewise, there is no need to assume trust between the players: The use of reciprocity can be enough to make defection unproductive. Altruism is not needed: Successful strategies can elicit cooperation even from an egoist. Finally, no central authority is needed: Cooperation based on reciprocity can be self-policing
  • An indefinite number of interactions, therefore, is a condition under which cooperation can emerge

      This condition is especially important in the case of egoists. Relationship over time.
  • So there must be some clustering of individuals who use strategies with two properties: The strategy cooperates on the first move, and discriminates between those who respond to the cooperation and those who do not

      The check for reciprocation is a bit of evidence that the other side knows the value of the move of cooperation; that they won't be abandoned.
  • Whether the players trust each other or not is less important in the long run than whether the conditions are ripe for them to build a stable pattern of cooperation with each other
  • It turns out that if one waits to respond to uncalled-for defections, there is a risk of sending the wrong signal. The longer defections are allowed to go unchallenged, the more likely it is that the other player will draw the conclusion that defection can pay.

      Immediate feedback appears to be important in many domains.
  • The foundation of cooperation is not really trust, but the durability of the relationship.
  • Waiting for probes to accumulate only risks the need for a response so large as to evoke yet more trouble.

      I have found that testing limits is a factor in working with children and adults. We are alert to the boundaries.
  • For this reason, the only arms control agreements which can be stable are those whose violations can be detected soon enough. The critical requirement is that violations can be detected before they can accumulate
  • Therefore, the advice to players of the Prisoner’s Dilemma might serve as good advice to national leaders as well: Don’t be envious, don’t be the first to defect, reciprocate both cooperation and defection, and don’t be too clever.
  • We are used to thinking about competitions in which there is only one winner, competitions such as football or chess. But the world is rarely like that. In a vast range of situations, mutual cooperation can be better for both sides than mutual defection. The key to doing well lies not in overcoming others, but in eliciting their cooperation

      Herein lies another key... that we have a cooperative (win-win) attitude and understanding of the "game". We see our survival as tied with not exclusive of the fate of the "other".

    I believe all people should try to understand what's at stake here. Let's feriousosly oppose any move that could lead to the net doesn't get hyacked by particumar interests monopolies and partisan hegemonies. Let's not allow discouragement to take the upper hand, let's not get influenced by the fact that all prior information empires have been.through, if we have to believe Tim Wu in his book the Master Switch, But let's be watchfull, very watchfull indeed. This time the fate of closed hegemonies getting the upper hand should be disavowed. People who still believe in freedom, equity, and humanness, please, let's band together beyond all our differences tp disavow this fate. Democracy and our grandchildren's life are at stake

      Learning is more active? It appears that communities networks and the like require engagement - meaning active

  • Driscoll (2000) defines learning as “a persisting change in human performance or performance potential…[which] must come about as a result of the learner’s experience and interaction with the world” (p.11).

      Our ability to learn - Process more than product.
  • An organizations ability to foster, nurture, and synthesize the impacts of varying views of information is critical to knowledge economy survival. Speed of “idea to implementation” is also improved in a systems view of learning.

      This is of special interest to me. Where the rubber meets the road.
  • The need to evaluate the worthiness of learning something is a meta-skill that is applied before learning itself begins.
  • These theories do not address learning that occurs outside of people (i.e. learning that is stored and manipulated by technology).

      While I accept that knowledge is organized and stored outside the "person". Learning is a distinctly internal process methinks. IOW - I don't get his point
  • Learning is a process that occurs within nebulous environments of shifting core elements – not entirely under the control of the individual.

      In the way that consciousness is an emergent property of the flow of energy within system of cells, neurons - Siemens idea of "learning" is the process through which individuals, ideas, and networks emerge (manifest). I don't know if this is what he's getting at but perhaps?
  • Capacity to know more is more critical than what is currently known

      Seems to me that what currently is known is equally important in that it guides us, grounds us, and forms the basis for our capacity. Wisdom or knowledge. Dichotomous.
  • Behaviorism, cognitivism, and constructivism are the three broad learning theories most often utilized in the creation of instructional environments. These theories, however, were developed in a time when learning was not impacted through technology.
  • Learning needs and theories that describe learning principles and processes, should be reflective of underlying social environments
  • The “half-life of knowledge” is the time span from when knowledge is gained to when it becomes obsolete.
  • To combat the shrinking half-life of knowledge, organizations have been forced to develop new methods of deploying instruction.”
