Quote:

One of these new technologies was a humble-looking black box known was a Random Event Generator (REG). This used computer technology to generate two numbers - a one and a zero - in a totally random sequence, rather like an electronic coin-flipper.

The pattern of ones and noughts - 'heads' and 'tails' as it were - could then be printed out as a graph. The laws of chance dictate that the generators should churn out equal numbers of ones and zeros - which would be represented by a nearly flat line on the graph. Any deviation from this equal number shows up as a gently rising curve.

During the late 1970s, Prof Jahn decided to investigate whether the power of human thought alone could interfere in some way with the machine's usual readings. He hauled strangers off the street and asked them to concentrate their minds on his number generator. In effect, he was asking them to try to make it flip more heads than tails.

It was a preposterous idea at the time. The results, however, were stunning and have never been satisfactorily explained.

Again and again, entirely ordinary people proved that their minds could influence the machine and produce significant fluctuations on the graph, 'forcing it' to produce unequal numbers of 'heads' or 'tails'.




What do you think? I saw a program not to long ago about a scientist who built a robotic arm to perform a specific task. The arm was designed to use random numbers of movements to move a coin from one position to another. When a human concentrated on the movement the machine on average performed much fewer steps than when it was left alone.

I think this explains why some people are lucky in Las Vegas.

To bad I'm not lucky.

I think this explains that some people do not understand the meaning of random sequence.

Again, somebody that doesn't understand random sequences. Just because the number of ones and zeros are nearly equal, there can... and will... be long sequences of apparent patterns... With numbers between 0 and 9, a random sequence will have each digit appear by itself one time in ten, while double digits (00, 11, etc) should appear 1 time in 100, etc. Random does not mean pattern free.

> The arm was designed to use random numbers

There is no such thing as a 'random number'. There are random number sequences, but not random numbers.

There's a link to the actual research. I've heard a lot of bad things about how they structure the results, though, in order to make the results look more appealing than they are.

So far using samples of 100 results every half second, it hasn't deviated more than 20% on its own...  So if someone wants to try and manipulate over distance, hit me up on IRC :smile:

The arm was designed to use random numbers of movements to move a coin from one position to another.

Was that sentence so incredibly hard to understand? I mean the arm was designed move an object. Instead if it doing so in one steady motion it would move back and forth randomly before it finally placed the object. Say on the first attempt it would use 20 movements while on the second attempt it would use 22 movements. Random number of movements.

I understand the meaning, I was refering to slot machines.

If the REG theory is true (I'm not saying it is) it could apply to current day slot machines. The machine constantly cycles a random sequence to determine where the reels stop. It selects a value the instant the "spin" button is pressed or as coins enter the machine.

Actually, it doesn't. This is what the casinos want you to think, but it simply isn't true. It is true that winning and loosing follow a random sequence, but the results of the spin are not random. The machines are designed to give "near wins" on losses. This gives the person playing the machine a sense of, "Oh, I was so close... maybe next time!" and they continue to play.

No, but I used to have friends that worked in the industry that explained it to me. Lemme dig...

http://www.wizardofodds.com/slots/:

Below are some of the biggest myths about slot machines:

* Slot machines stop on any possible set of stops with equal probability

As explained above this is not true of modern single line slot machines. Some stops are much more likely than others.

* Slot machines are programmed to go through a cycle of payoffs. Although the cycle can span thousands of spins once it reaches the end the outcomes will repeat themselves in exactly the same order as the last cycle

This is not true at all. Every trial is random and independent of all past trials.

... from http://vegasreference.com/games/slots/

By the way, each reel is typically weighted differently. That's why you're more likely to get jackpot symbols on the first and second reels (building the suspense) while failing to hit the symbol on the third reel.

... from http://robison.casinocitytimes.com/articles/16803.html

One way of encouraging continued play would be to tease the player by showing the "10X" symbol more frequently above or below the payline than an average of once every 33 1/3 opportunities. I believe that in most cases the probability of winning on any specific single play is random but that the selection of symbols appearing on the screen is not necessarily random.

If it were to generate 10,000 numbers, each time having a 50/50 chance of being 1 or 0, wouldnt the odds of there being 10,000 1's be the same as 5,000 1's and 5,000 0's? Each instance holding the odd's and not the total outcome itself?

Thats why i play the lotto numbers 1,2,3,4,5,6 because i figure they have the same odd's of being randomly selected as the other 1-53 have.

Here this article explains it way better than I can.
http://www.casinogambling.about.com/cs/slots/a/SlotRng.htm

Basically the REG picks a number, Then it looks up that number on a table to determine where the reels stop. So while there might be 4000000 different REG numbers, numbers 1 thru 10000 could all have the same reel stop while the jackpot would only be asigned one REG number.

No, since the number of ways of making 5000 ones and 5000 zeroes is much greater than the number of ways of making 10000 ones. But for a specific sequence of 5000 ones and 5000 zeroes, the probabilities are the same.
