Memories Change Over Time
Memories of dramatic events seem to be burned into our minds. It seems easy to recall where we were when we learned JFK was assassinated (before my time), Ronald Reagan was shot (middle school gym at the end of the day), Elvis died (in a car near the top of Massanutten Mountain on our way to my grandparents’ place), or on September 11, 2001 (checking email after sleeping late).
It all seems so clear, but how reliable are our memories of the events and the circumstances surrounding them? Not very, especially as time passes and discussions of the events contain information not available at first. For example, a Smithsonian magazine article notes that Karim Nader, a neuroscientist, examined his own memories of September 11 and found he had made some mistakes.
Nader, now a neuroscientist at McGill University in Montreal, says his memory of the World Trade Center attack has played a few tricks on him. He recalled seeing television footage on September 11 of the first plane hitting the north tower of the World Trade Center. But he was surprised to learn that such footage aired for the first time the following day. Apparently he wasn’t alone: a 2003 study of 569 college students found that 73 percent shared this misperception.
These changes are normal and expected. You store long-term memories by associating new information with things you already know. As you continue to receive information about an event, it becomes difficult to distinguish what occurred when. That’s why legal experts view eyewitness testimony as unreliable – humans are fallible, our memories especially so.
When you’re an improviser, this fallibility works to your advantage. Long-form shows can run for 45 minutes or more and, given the huge number of choices performers make, inconsistencies crop up all the time. The good news is that your audience wants you to succeed and, unless the error is too big to ignore, they’re almost always willing to go along with the new reality. Not doing so would undermine their enjoyment of the show, so they have an incentive to play along.
This forgiving atmosphere isn’t present in politics and business, at least not for your competitors. They want you to fail and will bring up every instance of you ignoring or, in their opinion, attempting to mischaracterize the past. It doesn’t help when a campaign adviser admits that’s what you plan to do. As reported in a CNN.com article on March 21, 2012:
Eric Fehrnstrom, Romney’s senior campaign adviser, was asked in a CNN interview Wednesday morning whether the former Massachusetts governor had been forced to adopt conservative positions in the rugged race that could hurt his standing with moderates in November’s general election.
“I think you hit a reset button for the fall campaign. Everything changes,” Fehrnstrom responded. “It’s almost like an Etch A Sketch. You can kind of shake it up, and we start all over again.”
Ouch. I anticipate the Etch A Sketch will be a theme in the 2014 and 2016 election cycle. Regardless, the lesson to draw from this incident is the same for both improv and business: Don’t abuse your audience’s goodwill.

Episodic and Semantic Memory
If I ask you to tell me what 3+2 equals, you would probably do so instantly. On the other hand, if I ask you to name in the last movie you saw the theater, you might have to think about it for a second or two. Those two different types of recall illustrate the differences between semantic memory and episodic memory.
I’ll start with episodic memory first. As the name implies, episodic memory is a form of long-term memory that records events from your life. Such episodes might include your wedding, the birth of a child, or something as mundane as getting out of a cab and stepping directly into a puddle. These episodes make up your internal autobiography, which is your personal record of your experiences.
Semantic memory, by contrast, refers to a subconscious knowledge that forms the basis for how we speak our native language, perform tasks we’ve done thousands of times, or interact in social settings. Semantic knowledge is often tacit, meaning that it is hard to quantify or describe. In many cases there is no need to write down the rules of behavior because everyone in the situation knows precisely what they are supposed to do. You’ll find this is true of families around the dinner table or groups of friends who go out for drinks after work.
Episodes from your life provide terrific fodder for scenes if you’re an improviser or for presentations in business. The trick is to find episodes that are directly relevant to your audience’s needs and to resist the temptation to stray too much from the truth. It’s one thing to tell your significant other a slightly exaggerated version of your exploits, but it’s quite another to tell an obviously untrue story in a business presentation. Conference goers have seen lots of presentations and they can smell a fake a mile away. Play it straight—don’t give in to the temptation to exaggerate too much.
Prisoner’s Dilemma, Part 5
This is the final post in my series on the Prisoner’s Dilemma. Five blog posts might seem like a lot, but many doctoral dissertations have been written on the ramifications of this deceptively simple game.
Robert Axelrod was one of first researchers to study how competing strategies for playing the Prisoner’s Dilemma interacted in a tournament setting. One of Axelrod’s main conclusions is that you can maximize your payoff in a Prisoner’s Dilemma tournament by following a nice strategy. That is, not defecting first. He also noted that it was possible for other strategies to beat the winner, Tit for Tat, by defecting first to get the higher payoff and then defecting every turn thereafter to ensure that the other program could never retaliate effectively. Over time, this strategy does not yield a higher payoff than the nice Tit for Tat; the aggressive strategy did not win either tournament.
But what happens if you put the nice Tit for Tat in an environment with a lot of aggressive programs? The answer is that Tit for Tat will always give up the higher payoff to its opponent in the first round and get the minimum payoff in every subsequent round. Based on those rules, Tit for Tat is guaranteed to lose. If you were to put a set of strategies into a tournament and then eliminate the bottom half of the field, Tit for Tat would always be eliminated, and the other more successful strategies would continue on. Those strategies being the aggressive, not nice, strategy of always defecting first and continuing to do so on every subsequent turn.
This type of attack is called an invasion. If you run a tournament and eliminate the bottom half of the field at the end of each run you’ll find certain strategies win out. If you introduce even a small number of these dominant strategies into a tournament, they will eventually take over. The problem becomes even worse if you create a series of strategies that can recognize kindred spirits, enabling them to work together to maximize their payoff by cooperating.
You can find the same type of behavior in business. In many cases when the group or company starts, you’ll find that everyone cooperates. The problem comes in when someone who doesn’t cooperate starts to get some success in the company. As the aggression is rewarded, other individuals adopt the same strategy. In time, those players can squeeze out the players who play a nice, cooperative strategy within the business. It’s a true management headache, one that is extremely difficult to stamp out once it gets started. Plus, as the aggressive players get promoted higher and higher, the reward structure changes. Now individuals who are willing to work with the aggressive individuals are rewarded with their own promotions and higher responsibilities.
In most cases, the company can continue on with this type of environment, despite the fact that there is a lack of trust among the players. In fact, this type of environment can fuel creativity for those individuals who revel in interpersonal conflict and feel it helps their creativity. At the same time, though, an organization might begin to experience problems associated with a lack of cooperation. Always looking to put one over on the other guy makes it difficult to trust anyone else, especially when you’re looking over your shoulder to see who will get the next promotion. These behaviors can lead to stress, burnout, and high turnover. In a company that requires highly skilled personnel, losing a solid contributor because of a toxic work environment is extremely costly.
In improvisational comedy groups, you find the same thing happens especially at the beginning of the group’s life. As individuals jockey for position within the group and try to have an impact on how things will be run, you will often find that individuals who started in the group either drop out or get kicked out after they try to change the group through aggression or passive aggression by not following directions of the group’s leadership. Well-established organizations with a solid player roster and workshops from which to bring in new players are less susceptible to this sort of issue. The group’s culture is solid, and the workshop process allows management to decide which players will be promoted and included in the team.
Smaller groups, such as touring companies with only four or five players, can be susceptible to problems. The trick, as always, is to select your fellow performers wisely. In many cases, it’s better to join another group or start a new group of your own than it is to continue on in a bad situation. Sometimes leaving a bad job is the best thing you could possibly do.
Prisoner’s Dilemma, Part 4
I’ve spent the last few posts talking about the Prisoner’s Dilemma, where two individuals must decide whether or not to cooperate. There’s a harsh penalty for having one’s trust violated, so the most risk-averse strategy is to violate the other player’s trust. RobertAxelrod’s analysis gives us a number of results that we can use both in the realm of improv and in the realm of business. He enumerated these five principles in The Evolution of Cooperation:
- Enlarge the shadow of the future
- Change the payoffs
- Teach people to care about each other
- Teach reciprocity
- Improve negotiation abilities
Enlarging the shadow of the future simply means taking a long view of your interactions. When you form an improvisational comedy group, you should plan to have many performances over a number of months or years. This sort of ongoing interaction, like any other relationship, requires nurturing and mutual trust. Just like saving for retirement, the more you set aside in terms of money or trust at the start, the higher your return and, as the years go by, the interest accumulates. The same principle holds for business interactions. Americans on the West Coast tend to change jobs a lot more often than folks on the East Coast, but many of us stay within the same industry and interact with our colleagues from previous jobs frequently. Within a company, you’ll find that fostering a spirit of cooperation on your team will help you generate better results. Hopefully that conclusion won’t be too surprising.
The next question is how to reward different behaviors. In the classic Prisoner’s Dilemma payoff matrix, the only logical choice is to defect. Doing so limits the damage that would be caused by trusting another individual whose rational calculus would push them to defect. In business, anyone who sees their business as a series of one-time relationships will not be all that keen on building a trusting relationship with their business partners. In the entertainment industry, it said that you haven’t really sold someone until you’ve done business with them twice. If they’re not willing to rehire you, it means that they don’t trust you based on their experience with you.
Teaching people to care about each other can be tricky, particularly if you have individuals who are not prone to trusting relationships with others. Sociopaths, who don’t empathize with other individuals at all, are a particular problem. I’m not a psychologist, so I can’t tell you how to deal with them, but there are a number of online resources that you can use to see where to go and what to do. For individuals who do have feelings toward others, you can use teambuilding exercise rewards and the warm afterglow of successful shows or projects to develop a sense of camaraderie.
In the improv world, in which interactions in local groups are reasonably equal, you don’t often have that much trouble with these relationships. Yes, every so often members of the group will disagree intensely, but if everything is in place and the relationship is solid, it’s likely that you will get through the difficulties. In a business in which promotions, internal awards, and raises are at issue, the stakes are quite a bit higher. Managers need to keep everyone’s wants, needs, and desires in mind as they manage their projects.
One of the best ways to ensure people are satisfied is to give them work they care about and reward them for doing good jobs. The nature of those rewards will vary based on your business and the resources available to you, but rewards and recognition, even if only at the personal level, go a long way toward making those relationships more solid.
Axelrod also recommends that you learn to teach reciprocity. A willingness to respond to offers of cooperation allows teams to make much more progress than a loose collection of individuals would be able to. The form that reciprocity takes depends upon your organization. For businesses, providing a bit of after-hours help for others on their part of a project after they have done the same for you is a perfect example. In the improv world, we can try to “set up players for the slam.” Just as volleyball players run through the bump, set, spike sequence to go from defense to offense, improvisers can do their fellow players a favor by giving them straight lines, by allowing them to be the focus of the scene, and by staying off the stage when their presence is not strictly necessary. All these actions are judgment calls that improve with experience, but managers can improve their odds, both in the performance and business worlds, by bringing on individuals who are predisposed toward these behaviors.
Finally, you should improve your negotiation skills. Negotiation is the art of the compromise, and there are very few solutions that will meet everyone’s wants and desires. Some folks have to compromise, some more than others, and good leaders and team members will find ways to negotiate for what they feel is necessary and compromise when it’s called for.
Prisoner’s Dilemma, Part 3
My previous two posts discussed the Prisoner’s Dilemma, a classic 2 x 2 game structured so each player feels compelled to violate the trust of the other player. Researcher Robert Axelrod tried to find the best strategy for playing the Prisoner’s Dilemma by holding a tournament among computer programs playing the Prisoner’s Dilemma. Every program would play every other program, a second copy of itself, and a program Axelrod created that randomly chose whether to cooperate or defect. In that first tournament, which had 14 entrants, a program by Anatol Rapoport named Tit for Tat won.
The strategy behind Tit for Tat is extremely simple: Start out by cooperating, but if the other player defects, defect on the next turn as punishment. If the other player did not defect on the next turn, the program would switch back to cooperating. So why would this program win? As Stevens points out in his course, the best the program can hope to do is to tie. It never tries to take advantage of the other player, so it will never get a higher payoff in any round than the other program. What happened was that Tit for Tat minimized its losses. It punished other programs for defecting, but it only did so once if there was just a single defection. This strategy of minimizing its own losses while minimizing the other programs’ gain due to bad behavior made Tit for Tat the best program of the bunch.
The key to the success of Tit for Tat is that it elicits cooperation. Axelrod noted that the program is nice, provokable, forgiving, and straightforward. Among humans playing the game, or for computer programs with a memory of past turns, playing Tit for Tat lets other player accurately predict the consequences of their actions. In the first Prisoner’s Dilemma tournament, the top eight programs were all nice, which meant that they were never the first to defect.
The participants included a program called JOSS, which was the same as Tit for Tat but threw in the occasional defection at random intervals. The program’s design was meant to take advantage of the occasionally high payoff from an unchallenged defection while retaining the benefits of cooperation. Unfortunately, this strategy resulted in extremely low scores because its actions weren’t predictable. One very negative consequence was that it created a series of moves versus Tit for Tat, and variations of Tit for Tat, in which each program defected on alternate turns and led to dismally low scores.
In Axelrod’s analysis of the first tournament, he noted that there were three strategies not included in the tournament but that, if submitted, would have won. With these results made available to potential entrants, along with randomizing the number of rounds each pair of strategies competed against each other to invalidate “late round” tactics, he ran a second tournament. This new competition attracted 62 entries. Tit for Tat won again. From the results, it’s easy to see that there is a penalty for being the first to defect. Axelrod wrote:
What seems to have happened is an interesting interaction between people who drew one lesson and people who drew another from the first round. Lesson One was: “Be nice and forgiving.” Lesson Two was more exploitative: “If others are going to be nice and forgiving, it pays to try to take advantage of them.” The people who drew Lesson One suffered in the second round from those who drew Lesson Two….The reason is that in trying to exploit other rules, they often eventually got punished enough to make the whole game less rewarding for both players than pure mutual cooperation would have been.
The lessons for improv and business are obvious, so I won’t belabor them. I would point out that the Prisoner’s Dilemma is an inherently grim scenario, so it’s best not to get into this type of situation in the first place. Because each player faces potential catastrophe if they don’t protect themselves, you can allow the players to communicate and not guarantee cooperation.
Next up: further insights into the nature of competition in the Prisoner’s Dilemma scenario.
Prisoner’s Dilemma, Part 2
In my previous post, I described the Prisoner’s dilemma, a classic 2 x 2 game structured so the players are coerced into violating the trust of the other player. The strategy for a single round of the Prisoner’s dilemma is to defect, selling out the other player and eliminating the prospect of a huge negative outcome for yourself. But what about playing the game multiple times, perhaps many times?
Improv groups and businesses are meant it to be long-lived entities. The group I’m with, ComedySportz Portland, was founded in 1993 – as of this writing, we’ve been around for 19 years. I like to joke that it means we’ve lasted 38 times longer than the average improv group. Sure, there are plenty of groups that have been around for a long time, but there are quite a few more that have blown up in very short order.
What makes some groups stay together and others break apart? One thing that can make it happen is taking advantage of the other individuals in your group, whether by not making good on your promises or by not cooperating during scenes. Some examples of not cooperating can include making personal comments at another player’s expense, such as about their weight, height, or the choices that they made; denying other players’ choices during a scene or game; or showing up late (or not at all) to a rehearsal or performance. Taking advantage of the goodwill of your fellow players is extremely shortsighted. Forming a successful group is incredibly difficult, so you should do your best to ensure the group you’re with carries on, or at least that you don’t burn any bridges if you do decide to leave.
As Robert Axelrod noted in his book, The Evolution of Cooperation, and Scott Stevens noted in his Games People Play course for The Great Courses, the more likely it is for the game to continue, the more incentive you have to continue cooperating throughout the entire game. The same consideration applies to business relationships. Con artists can get money out of their victims and disappear knowing that, if their luck holds, they will never have to encounter that individual again. For business professionals, you have to take the opposite approach. Even though many of us change jobs and industries, it’s very likely that we will encounter the same individuals during our work lives. We should cultivate the best relationships we can. In game theoretic terms, that means we should cooperate whenever possible.
Dialogue and Cooperative Play
Success at improv and business requires the clear communication of ideas and a willingness to incorporate others’ contributions into your work. This interchange doesn’t just happen verbally…among architects, this type of exchange happens on paper. In an opinion piece published in the September 2, 2012 New York Times, architect and Princeton professor (emeritus) Michael Graves wrote about an unspoken dialogue he had with a colleague during a boring faculty meeting:
While we didn’t speak, we were engaged in a dialogue over this plan and we understood each other perfectly. I suppose that you could have a debate like that with words, but it would have been entirely different. Our game was not about winners or losers, but about a shared language. We had a genuine love for making this drawing. There was an insistence, by the act of drawing, that the composition would stay open, that the speculation would stay “wet” in the sense of a painting. Our plan was without scale and we could as easily have been drawing a domestic building as a portion of a city. It was the act of drawing that allowed us to speculate.
Players from the ComedySportz Portland improv group love the game of Paper Telephone. The idea is that you write a starting line at the top of a piece of paper, then pass it to a friend. Your friend reads the first line, writes a second line, and then folds the paper so only the most recent line is visible. You continue passing the paper around until there’s no more room, then unfold the paper and read the story. A fun variation is to have as many pieces of paper as there are players so you get lots of stories. The results are often hilarious and the similarities among stories can be eerie.
If you haven’t played Paper Telephone, you might have written stories with a friend, trading off after every paragraph. I’ve found this method works well for developing business presentations. Sit down with two or three of your colleagues and take turns telling a story or building an outline one line at a time. Don’t worry about coherence or order yet — all you want to do is get the information down so you can revise it later. This type of cooperative play helps you get beyond the creative person’s nightmare: a blank page.
