Scissors-paper-rock, the universal game where there in no best move. Winning a game is all down to chance right? There is always a action that you will beat, and an action that will beat you, how can you possibly know what will win? By identifying patterns in the way humans play Chinese researchers may have the key to a better strategy.

In the investigation 360 students were arranged into groups of 6 and studied 18 000 rounds of the game. It was noticed that the most popular choice was rock, but only by a small amount, followed by paper and then scissors.

They also discovered a pattern in the way we play. If we win we a most likely to stick with the same sign again, and if we lose we tend to switch from rock to scissors, scissors to paper and paper to rock. This is referred to as the 'win-stay, lose-switch' strategy.

This strategy is quite helpful in terms of real life. If someone provides a product that is doing well they will stay with making the same sort of products, but if the product inst doing too well that are likely to start doing something different. Its a good thing to do in life, play around with it until you find something that works for you, but in rock-paper-scissors it may not be such a good thing.
Rock paper scissors game

With this in mind a better strategy might be to switch in the following way.

If you win:
(and your opponent doesn't know this strategy)

If you won with rock switch to scissors. By using these patterns your opponent is likely to use paper next.

With scissors switch to paper, since your opponent is probably going to use rock next.

For a win with paper switch to rock, as when they switch to scissors you will be able to beat them.

If you lose :

These patterns do follow the pattern that is most predictable, but will work provided your opponent stays with the same sign.

If your loss was caused by throwing rock, throw scissors. They will stay on paper and you can beat them this way.

With scissors switch to paper, as they will most likely still be using rock.

A loss with paper calls for a switch to rock, which can beat their scissors.

But what if they know this strategy too! Maybe you can try this

A loss with rock calls for paper, when they switch to scissors you will win that round.

Losing with scissors means changing to rock, which will beat their switch to scissors.

When you've lost by throwing paper switch to scissors, which will win over their paper.

Urine sample wikipedia free image
Aside from the fact that people during the Middle Ages tended to bathe rather infrequently, in fact Summer being the only real bathing time, did you realise that to assist with their bathing needs, they were also washing themselves with urine?

In fact a little bit of wee went a long way in those days. It was mixed into the soap that they used during bathing, and it was also used as a washing detergent for their clothing. White clothing in particular was used with urine in order to keep it white.

Facebook icon
With the growing concerns involving Facebook and its ever changing privacy settings, a few software developers have now engineered a website that allows users to trawl through the status updates of anyone who does not have the correct privacy settings to prevent it.

Named Openbook, the ultimate aim of the site is to further expose the problems with Facebook and its privacy settings to the general public, and show people just how easy it is to access this type of information about complete strangers. The site works as a search engine so it is easy to search terms such as "don't tell anyone" or "I hate my boss", and searches can also be narrowed down by gender.
