My experiences as a tabletop and video gamer have taught me numerous lessons that are applicable to the real world (assuming there is such a thing). One key skill in getting about in reality is the ability to model reality. Roughly put, this is the ability to get how things work and thus make reasonably accurate predictions. This ability is rather useful: getting how things work is a big step on the road to success.
Many games, such as Call of Cthulhu, D&D, Pathfinder and Star Fleet Battles make extensive use of dice to model the vagaries of reality. For example, if your Call of Cthulhu character were trying to avoid being spotted by the cultists of Hastur as she spies on them, you would need to roll under your Sneak skill on percentile dice. As another example, if your D-7 battle cruiser were firing phasers and disruptors at a Kzinti strike cruiser, you would roll dice and consult various charts to see what happened. Video games also include the digital equivalent of dice. For example, if you are playing World of Warcraft, the damage done by a spell or a weapon will be random.
Being a gamer, it is natural for me to look at reality as also being random—after all, if a random model (gaming system) nicely fits aspects of reality, then that suggests the model has things right. As such, I tend to think of this as being a random universe in which God (or whatever) plays dice with us.
Naturally, I do not know if the universe is random (contains elements of chance). After all, we tend to attribute chance to the unpredictable, but this unpredictability might be a matter of ignorance rather than chance. After all, the fact that we do not know what will happen does not entail that it is a matter of chance.
People also seem to believe in chance because they think things could have been differently: the die roll might have been a 1 rather than a 20 or I might have won the lottery rather than not. However, even if things could have been different it does not follow that chance is real. After all, chance is not the only thing that could make a difference. Also, there is the rather obvious question of proving that things could have been different. This would seem to be impossible: while it might be believed that conditions could be recreated perfectly, one factor that can never be duplicated – time. Recreating an event will be a recreation. If the die comes up 20 on the first roll and 1 on the second, this does not show that it could have been a 1 the first time. All its shows is that it was 20 the first time and 1 the second.
If someone had a TARDIS and could pop back in time to witness the roll again and if the time traveler saw a different outcome this time, then this might be evidence of chance. Or evidence that the time traveler changed the event.
Even traveling to a possible or parallel world would not be of help. If the TARDIS malfunctions and pops us into a world like our own right before the parallel me rolled the die and we see it come up 1 rather than 20, this just shows that he rolled a 1. It tells us nothing about whether my roll of 20 could have been a 1.
Of course, the flip side of the coin is that I can never know that the world is non-random: aside from some sort of special knowledge about the working of the universe, a random universe and a non-random universe would seem exactly the same. Whether my die roll is random or not, all I get is the result—I do not perceive either chance or determinism. However, I go with a random universe because, to be honest, I am a gamer.
If the universe is deterministic, then I am determined to do what I do. If the universe is random, then chance is a factor. However, a purely random universe would not permit actual decision-making: it would be determined by chance. In games, there is apparently the added element of choice—I chose for my character to try to attack the dragon, and then roll dice to determine the result. As such, I also add choice to my random universe.
Obviously, there is no way to prove that choice occurs—as with chance versus determinism, without simply knowing the brute fact about choice there is no way to know whether the universe allows for choice or not. I go with a choice universe for the following reason: If there is no choice, then I go with choice because I have no choice. So, I am determined (or chanced) to be wrong. I could not choose otherwise. If there is choice, then I am right. So, choosing choice seems the best choice. So, I believe in a random universe with choice—mainly because of gaming. So, what about the lessons from this?
One important lesson is that decisions are made in uncertainty: because of chance, the results of any choice cannot be known with certainty. In a game, I do not know if the sword strike will finish off the dragon. In life, I do not know if the investment will pay off. In general, this uncertainty can be reduced and this shows the importance of knowing the odds and the consequences: such knowledge is critical to making good decisions in a game and in life. So, know as much as you can for a better tomorrow.
Another important lesson is that things can always go wrong. Or well. In a game, there might be a 1 in 100 chance that a character will be spotted by the cultists, overpowered and sacrificed to Hastur. But it could happen. In life, there might be a 1 in a 100 chance of a doctor taking precautions catching Ebola from a patient. But it could happen. Because of this, the possibility of failure must always be considered and it is wise to take steps to minimize the chances of failure and to also minimize the consequences.
Keeping in mind the role of chance also helps a person be more understanding, sympathetic and forgiving. After all, if things can fail or go wrong because of chance, then it makes sense to be more forgiving and understanding of failure—at least when the failure can be attributed in part to chance. It also helps in regards to praising success: knowing that chance plays a role in success is also important. For example, there is often the assumption that success is entirely deserved because it must be the result of hard work, virtue and so on. However, if success involves chance to a significant degree, then that should be taken into account when passing out praise and making decisions. Naturally, the role of chance in success and failure should be considered when planning and creating policies. Unfortunately, people often take the view that both success and failure are mainly a matter of choice—so the rich must deserve their riches and the poor must deserve their poverty. However, an understanding of chance would help our understanding of success and failure and would, hopefully, influence the decisions we make. There is an old saying “there, but for the grace of God, go I.” One could also say “there, but for the luck of the die, go I.”
