Researchers Tell Us The Strategies To Win Rock-Paper-Scissors

Researchers Tell Us The Strategies To Win Rock-Paper-Scissors

As kids, we all played rock-paper-scissors on a weekly if not daily basis. Why? Because it was a simple (and fun) way to make decisions, one that made both people feel like they had a shot at winning.

Some of us might still play the game today, though perhaps the stakes aren’t quite as high as they were when we were kids!

Have you, however, ever thought about the strategy behind rock-paper-scissors? Can you, for instance, play in a way that maximizes your chances of winning?

The answer is yes, but what may or may not surprise you is that most people don’t take advantage of that fact.

Recently, researchers in Zhejiang, China ran one of the largest rock-paper-scissors studies in history. They had 360 people playing with each other in games of rock-paper-scissors, with their strategies carefully documented. To ensure each played to win, they were paid based on how many victories they achieved.

Their goal was to see if humans would play the game properly — that is, in the manner that would statistically result in the most victories.

This winning strategy is simpler than you might imagine. Indeed, all you have to do is make your selections randomly, or in other words, in each round of rock-paper-scissors, there needs to be a 1/3 chance that you pick either rock, paper, or scissors.

But, as the researchers note in their findings (which can be read here), “decision-making and learning are very complicated neural processes,” and thus, what they found surprised them.

While the 360 people taking part in the research experiment seemed to choose random selections on average, there was another underlying trend that the researchers found after digging a bit deeper into their findings.

What they discovered was that those who won a round of rock-paper-scissors were more likely to stick with the choice that brought them victory. Those who lost, they discovered, were more prone to change their selection.

However, what is interesting is that losers chose their next option in a cyclical manner, meaning those who picked rock and lost were more likely to choose paper next, and those who chose paper were more likely to choose scissors, and so on and so forth.

This kind of conditional response was dubbed “the win-stay lose-shift strategy,” which has interesting implications when it comes to understanding human nature, and the game of rock-paper-scissors itself.

    Thus, what the researchers concluded is that victory in rock-paper-scissors isn’t dependent on the classical game theory notion that each player play completely randomly to win the game (otherwise known as the Nash Equilibrium for those of you who remember statistics class).

    This is because, as the researchers put it, “[rock-paper-scissors] exhibits collective cyclic motions which cannot be understood by the Nash Equilibrium concept but are successfully explained by the empirical data-inspired conditional response mechanism.”

    Or in other words, to be effective at rock-paper-scissors, you need to know your opponent. Victory is based on reacting to how they play, much more so than it is based on randomly throwing out rock, paper, or scissors. Since this study reveals that most winners stick to their choice, and most losers cyclically move to the next option, you can use that to your advantage to beat novice players of rock-paper-scissors.

    The researchers do note that experienced players of the game are likely to be reactive to your strategies, and thus are far more difficult to defeat. They also say, however, that facing an opponent good enough to break away from the win-stay lose-shift strategy is “rare,” meaning you can raise your chances of victory (on average) by assuming most humans will stick to the simpler, reflex-based strategy.

    I think we all sort of knew this though based on our experience with rock-paper-scissors. The game was never about being random, it was about trying to predict your opponent’s tendencies and using them to your own advantage. This research simply confirms that to be the case, and gives us the template by which to achieve as many victories against the average player as possible.

    These findings might have implications beyond the world of simple hand games as well. If most humans are prone to reflexive choices, rather than reactive ones, then that might say something not only about how our brains are wired, but about how many of the world’s systems work (for example, the financial market). As such, the researchers say that their next study will be going more in-depth in terms of investigating the nature of our “irrational” choices.

    While there are still many more questions to be answered, you can at least rest easy knowing that with the knowledge above, you’ll be able to outplay the majority of the human population when it comes to rock-paper-scissors.

    Just be sure you don’t challenge someone who’s also familiar with this strategy, else you might have to up your game just a little bit!

    10 Steps For Success: Applying The Power Of Your Subconscious Mind

    10 Steps For Success: Applying The Power Of Your Subconscious Mind

    How big is the gap between you and your success?

    What is the difference between successful people and unsuccessful people?

    It is as simple as this: successful people think and talk about what they are creating, and unsuccessful people focus on and talk about what they’re lacking.

    So how do you bridge that gap between wanting success and having your success? Let’s make an important distinction. You see, there is a big difference between “Wanting” and “Having” something.

    Wanting: means lacking or absent. Deficient in some part, thing or aspect.

    Having: means to possess, to hold, to get, to receive, to experience.

    You can have one OR the other, but not both at the same time with any particular object of your desire. You either have it or you don’t.

    When it comes to your subconscious, if you’re focusing on the “wanting”, i.e. the not having, guess what, you will build stronger neural networks in your brain around the “wanting.” However, through the power of your subconscious mind, you can focus on the “having” as if it has already happened. Research has shown that your brain doesn’t know the difference between what you’re visualizing inside your mind versus what is happening out there in your reality.

    This is a regular practice of elite athletes. They spend as much timing creating the internal mental imagery of their success playing out as they do actually physically practicing. This helps create both the neural pathways in their brain and the muscle memory to consistently deliver on that success.

    Here are 10 “brain hack” steps for success that you can take to create your version of a happy life. Make these steps a regular habit, and you will be astonished at the results.

    Step 1: Decide exactly what you want to create and have

    This is usually the biggest problem that people have. They don’t know what they want and then they’re surprised when they don’t get it.

    Step 2: Write down your goal clearly in every technicolor detail

    A goal that is not written down is merely a wish. When you write it down in full detail, you signal to your subconscious mind that you really want to accomplish this particular goal.

    Step 3: Write your goal in simple, present tense words

    …that a three year old can understand on a three-by-five index card and carry it with you. Read it each morning after you awake and just before you go to sleep.

    Step 4: Backwards planning

    See your goal achieved and identify all the steps required that it took to bring it to life. Making a list of all these steps intensifies your desire and deepens your belief that the attainment of the goal is already happening.

    Step 5: Resolve to take at least one step every day from one of the items on your list

    Do something every day, even if it is just one baby step, that moves you toward your goal so you can maintain your momentum.

    Step 6: Visualize your goal repeatedly

    See it in your mind’s eye as though it were already a reality. The more clear and vivid your mental picture of your goal, the faster it will come into your life.

    Step 7: Feel the feeling of success as if your goal were realized at this very moment

    Feel the emotion of happiness, satisfaction, and pleasure that you would have once you have achieved your goal. Visualize and feel this success for at least 20 seconds at a time.

    Step 8: “Fake it till you make it!”

    Confidently behave as if your subconscious mind was already bringing your goal into reality. Accept that you are moving toward your goal and it is moving toward you.

    Step 9: Relax your mind

    Take time to breathe, pray or mediate each day. Disengage the stress response and engage the relaxation response. A quiet state of mind allows your brain to access newly formed neural pathways.

    Step 10: Release your goal to your subconscious mind

    When you turn your goal over to the power of the universe and just get out of the way, you will always know the right actions to take at the right time.

    Starting today, try tapping into the incredible power of your subconscious mind.Start with just one goal or idea, and practice it continually until you succeed in achieving that goal. Make it a game and have fun with it! The more lightly you hold it, the easier it will be to achieve. By doing so, you will move from the “positive thinking” of the hopeful person to the “positive knowing” of the totally successful person.

    Hit reply and let me know what you’re creating!

    To your success!
