How to Win at Rock-Paper-Scissors (and also how to cheat)

Earlier this month, our YouTube Hunter found some riveting rock-paper-scissors footage. Today, Rocketboom has more, including classic interviews with the world's best RPS athletes.

(That's right, I said RPS. If you want to sound like an insider at the upcoming World RPS Championships, you should too.)

Want to play like a champion, and compete for the $10,000 prize? From the World RPS Society:

Contrary to what you might think RPS is not simply a game of luck or chance. While it is true that from a mathematical perspective the 'optimum' strategy is to play randomly, it still is not a winning strategy for two reasons.

First, 'optimum' in this case means you should win, lose and draw an equal number of times (hardly a winning strategy over the long term). Second, Humans, try as they might, are terrible at trying to be random, in fact often humans in trying to approximate randomness become quite predictable. So knowing that there is always something motivating your opponent's actions, there are a couple of tricks and techniques that you can use to tip the balance in your favour.

The top secrets to winning at RPS -- courtesy of Graham Walker, Director of Management of the World RPS Society -- are after the jump.

1 - Rock is for Rookies
In RPS circles a common mantra is "Rock is for Rookies" because males have a tendency to lead with Rock on their opening throw. It has a lot to do with idea that Rock is perceived as "strong" and forceful", so guys tend to fall back on it. Use this knowledge to take an easy first win by playing Paper. This tactic is best done in pedestrian matches against someone who doesn't play that much and generally won't work in tournament play.
2 - Scissors on First
The second step in the 'Rock is for Rookies' line of thinking is to play scissors as your opening move against a more experienced player. Since you know they won't come out with rock (since it is too obvious), scissors is your obvious safe move to win against paper or stalemate to itself.
3 - The Double Run
When playing with someone who is not experienced at the RPS, look out for double runs or in other words, the same throw twice. When this happens you can safely eliminate that throw and guarantee yourself at worst a stalemate in the next game. So, when you see a two-Scissor run, you know their next move will be Rock or Paper, so Paper is your best move. Why does this work? People hate being predictable and the perceived hallmark of predictability is to come out with the same throw three times in row.
4 - Telegraph Your Throw
Tell your opponent what you are going to throw and then actually throw what you said. Why? As long as you are not playing someone who actually thinks you are bold enough to telegraph your throw and then actually deliver it, you can eliminate the throw that beats the throw you are telegraphing. So, if you announce rock, your opponent won't play paper which means coming out with that scissors will give you at worst a stalemate and at best the win.
5 - Step Ahead Thinking
Don't know what to do for your next throw? Try playing the throw that would have lost to your opponents last throw? Sounds weird but it works more often than not, why? Inexperienced (or flustered) players will often subconsciously deliver the throw that beat their last one. Therefore, if your opponent played paper, they will very often play Scissors, so you go Rock. This is a good tactic in a stalemate situation or when your opponent lost their last game. It is not as successful after a player has won the last game as they are generally in a more confident state of mind which causes them to be more active in choosing their next throw.
6 - Suggest A Throw
When playing against someone who asks you to remind them about the rules, take the opportunity to subtly "suggest a throw" as you explain to them by physically showing them the throw you want them to play. ie "Paper beats Rock, Rock beats scissors (show scissors), Scissors (show scissors again) beats paper." Believe it or not, when people are not paying attention their subconscious mind will often accept your "suggestion". A very similar technique is used by magicians to get someone to take a specific card from the deck.
7 - When All Else Fails Go With Paper
Haven't a clue what to throw next? Then go with Paper. Why? Statistically, in competition play, it has been observed that scissors is thrown the least often. Specifically, it gets delivered 29.6% of the time, so it slightly under-indexes against the expected average of 33.33% by 3.73%. Obviously, knowing this only gives you a slight advantage, but in a situation where you just don't know what to do, even a slight edge is better than none at all.
8 - The Rounder's Ploy
This technique falls into more of a 'cheating' category, but if you have no honour and can live with yourself the next day, you can use it to get an edge. The way it works is when you suggest a game with someone, make no mention of the number of rounds you are going to play. Play the first match and if you win, take it is as a win. If you lose, without missing a beat start playing the 'next' round on the assumption that it was a best 2 out of 3. No doubt you will hear protests from your opponent but stay firm and remind them that 'no one plays best of one for a kind of decision that you two are making'. No this devious technique won't guarantee you the win, but it will give you a chance to battle back to even and start again.

And if that's too hard to remember, here are some ways to cheat.

Yes, You Can Put Your Christmas Decorations Up Now—and Should, According to Psychologists

We all know at least one of those people who's already placing an angel on top of his or her Christmas tree while everyone else on the block still has paper ghosts stuck to their windows and a rotting pumpkin on the stoop. Maybe it’s your neighbor; maybe it’s you. Jolliness aside, these early decorators tend to get a bad rap. For some people, the holidays provide more stress than splendor, so the sight of that first plastic reindeer on a neighbor's roof isn't exactly a welcome one.

But according to two psychoanalysts, these eager decorators aren’t eccentric—they’re simply happier. Psychoanalyst Steve McKeown told UNILAD:

“Although there could be a number of symptomatic reasons why someone would want to obsessively put up decorations early, most commonly for nostalgic reasons either to relive the magic or to compensate for past neglect.

In a world full of stress and anxiety people like to associate to things that make them happy and Christmas decorations evoke those strong feelings of the childhood.

Decorations are simply an anchor or pathway to those old childhood magical emotions of excitement. So putting up those Christmas decorations early extend the excitement!”

Amy Morin, another psychoanalyst, linked Christmas decorations with the pleasures of childhood, telling the site: “The holiday season stirs up a sense of nostalgia. Nostalgia helps link people to their personal past and it helps people understand their identity. For many, putting up Christmas decorations early is a way for them to reconnect with their childhoods.”

She also explained that these nostalgic memories can help remind people of spending the holidays with loved ones who have since passed away. As Morin remarked, “Decorating early may help them feel more connected with that individual.”

And that neighbor of yours who has already been decorated since Halloween? Well, according to a study in the Journal of Environmental Psychology, homes that have been warmly decorated for the holidays make the residents appear more “friendly and cohesive” compared to non-decorated homes when observed by strangers. Basically, a little wreath can go a long way.

So if you want to hang those stockings before you’ve digested your Thanksgiving dinner, go ahead. You might just find yourself happier for it.

11 Black Friday Purchases That Aren't Always The Best Deal

Black Friday can bring out some of the best deals of the year (along with the worst in-store behavior), but that doesn't mean every advertised price is worth splurging on. While many shoppers are eager to save a few dollars and kickstart the holiday shopping season, some purchases are better left waiting for at least a few weeks (or longer).

1. FURNITURE

Black Friday is often the best time to scope out deals on large purchases—except for furniture. That's because newer furniture models and styles often appear in showrooms in February. According to Kurt Knutsson, a consumer technology expert, the best furniture deals can be found in January, and later on in July and August. If you're aiming for outdoor patio sets, expect to find knockout prices when outdoor furniture is discounted and put on clearance closer to Labor Day.

2. TOOLS

Unless you're shopping for a specific tool as a Christmas gift, it's often better to wait until warmer weather rolls around to catch great deals. While some big-name brands offer Black Friday discounts, the best tool deals roll around in late spring and early summer, just in time for Memorial Day and Father's Day.

3. BEDDING AND LINENS

Sheet and bedding sets are often used as doorbuster items for Black Friday sales, but that doesn't mean you should splurge now. Instead, wait for annual linen sales—called white sales—to pop up after New Year's. Back in January of 1878, department store operator John Wanamaker held the first white sale as a way to push bedding inventory out of his stores. Since then, retailers have offered these top-of-the-year sales and January remains the best time to buy sheets, comforters, and other cozy bed linens.

4. HOLIDAY DÉCOR

If you are planning to snag a new Christmas tree, lights, or other festive décor, it's likely worth making due with what you have and snapping up new items after December 25. After the holidays, retailers are looking to quickly move out holiday items to make way for spring inventory, so ornaments, trees, yard inflatables, and other items often drastically drop in price, offering better deals than before the holidays. If you truly can't wait, the better option is shopping as close to Christmas as possible, when stores try to reduce their Christmas stock before resorting to clearance prices.

5. TOYS

Unless you're shopping for a very specific gift that's likely to sell out before the holidays, Black Friday toy deals often aren't the best time to fill your cart at toy stores. Stores often begin dropping toy prices two weeks before Christmas, meaning there's nothing wrong with saving all your shopping (and gift wrapping) until the last minute.

6. ENGAGEMENT RINGS AND JEWELRY

Holiday jewelry commercials can be pretty persuasive when it comes to giving diamonds and gold as gifts. But, savvy shoppers can often get the best deals on baubles come spring and summer—prices tend to be at their highest between Christmas and Valentine's Day thanks to engagements and holiday gift-giving. But come March, prices begin to drop through the end of summer as jewelers see fewer purchases, making it worth passing up Black Friday deals.

7. PLANE TICKETS AND TRAVEL PACKAGES

While it's worth looking at plane ticket deals on Black Friday, it's not always the best idea to whip out your credit card. Despite some sales, the best time to purchase a flight is still between three weeks and three and a half months out. Some hotel sites will offer big deals after Thanksgiving and on Cyber Monday, but it doesn't mean you should spring for next year's vacation just yet. The best travel and accommodation deals often pop up in January and February when travel numbers are down.

8. FOOD AND SNACK BASKETS

Fancy fruit, meat and cheese, and snack baskets are easy gifts for friends and family (or yourself, let's be honest), but they shouldn't be snagged on Black Friday. And because baskets are jam-packed full of perishables, you likely won't want to buy them a month away from the big day anyway. But traditionally, you'll spend less cheddar if you wait to make those purchases in December.

9. WINTER CLOTHING

Buying clothing out of season is usually a big money saver, and winter clothes are no exception. Although some brands push big discounts online and in-store, the best savings on coats, gloves, and other winter accessories can still be found right before Black Friday—pre-Thanksgiving apparel markdowns can hit nearly 30 percent off—and after the holidays.

10. SMARTPHONES

While blowout tech sales are often reserved for Cyber Monday, retailers will try to pull you in-store with big electronics discounts on Black Friday. But, not all of them are really the best deals. The price for new iPhones, for example, may not budge much (if at all) the day after Thanksgiving. If you're in the market for a new phone, the best option might be waiting at least a few more weeks as prices on older models drop. Or, you can wait for bundle deals that crop up during December, where you pay standard retail price but receive free accessories or gift cards along with your new phone.

11. KITCHEN GADGETS

Black Friday is a great shopping day for cooking enthusiasts—at least for those who are picky about their kitchen appliances. Name-brand tools and appliances often see good sales, since stores drop prices upwards of 40 to 50 percent to move through more inventory. But that doesn't mean all slow cookers, coffee makers, and utensil prices are the best deals. Many stores advertise no-name kitchen items that are often cheaply made and cheaply priced. Purchasing these lower-grade items can be a waste of money, even on Black Friday, since chances are you may be stuck looking for a replacement next year. And while shoppers love to find deals, the whole point of America's unofficial shopping holiday is to save money on products you truly want (and love).
