Should a scientist never buy a lottery ticket?

In summary, the conversation discusses the argument that some people educated in math refuse to buy lottery tickets or play roulette because the average outcome is a loss. However, the conversation argues that this is not a valid argument as it doesn't take into account factors such as standard deviation and personal risk tolerance. It also touches on the addictive nature of gambling and the idea that it can be seen as a form of entertainment. The conversation concludes with a discussion of the standard deviation of profit in roulette, highlighting the need for a significant deviation from the expected value in order to have a positive outcome.

Ok, so multiply that by 50, and you have 15000 euros for 300 hours in 100 visits to the casino. That's a pretty hefty sum to lure you back there. Please report after the 100th visit.
You are entirely missing the point. There is a difference in playing a few times and many times. By continuing to play the odds of winning will decrease, that's when you become part of the average.

Throw a coin three times, what is the chance that you throw face all times? Now flip it 100 times, what is the chance to throw face all times?

So, are you suggesting that if you go only few times, your chances of winning are bigger?

Your chances of winning every time are bigger.

If you play RED every time you play roulette, it is true that each time you play, your odds of winning are 50/50 (or close to it, damn zeros).

If you play twice, your odds of winning each individual turn are still 0.50. However, your odds of winning BOTH, are now 0.25. As this goes on, the odds continue to diminish.

However, each time you play your odds are the same. Gambler's fallacies work both ways. There's no reason to assume that simply because you are doing well, you will soon lose big. If you have won three times already, your odds of winning again are still 50/50, despite the lower probability describing the higher level.

Winning meant making profit.

Expected Return is Negative.
But the concept of expected value is valid only for very large no. of trials.
So, its definitely No - No to play Lottery millions of times.

For just 1 trial or so, its just that you are buying probability. How much are you willing to buy a '1 in 10000 probability of winning $10000 ? ".
<you can't tell that its beneficial only if the ticket costs < 1$ ($10000 * 1/10000 = 1$), because, as previously told, this concept holds only for large no. of trials>

Those who feel they are lucky are more willing to pay for that small probability.
Even if we know the probability is so small, we may still buy the probability? The probability is small, but who knows, it just so happens to occur to me?

Seriously, I can't find any serious logic? Please help. :)

If you're trying to make the point that the house always wins of course you're right but why on Earth do you feel the need to explain that to me as though I didn't know it? Was I advocating somewhere in this thread that gambling is a good way to make money or that there is a way of ensuring you win all the time? No. Was anyone? No.

Ok, now I see the exact phrazing of the title. Anyone should buy a lottery ticket once in a while.

I was not trying to point anything to you, until you responded to my reply to Travis_King. Frankly, I don't care if you know or not, or what you think are simple facts. Some people do not understand those, and this is perpetuating a false optimism for gambling. You can see their psychology, when they start with the sentence:

"If I win on the first trial,..."

Wrong! There is a far bigger, or at least equal chance to lose on the first trial! Then, all the rest of the text is useless, unless they try again. And again.

Besides, the op was about lottery. Then, someone mentioned that gambling gives you better odds. I still oppose that statement. It gives you better odds, but the return is smaller, and is not worth your time. Then you pointed how you made 300 euros in 6 hours, and, I just tried to point out that is a one-time shot that you won't repeat again, so it is a useless fact, that could serve only to promote gambling.

No, you started all this with a snarky comment to monique that she must be a millionaire even though nothing she said indicated that she was claiming that she (or anyone) can gamble their way to success and what she said was a reasonable statement. I responded to that by pointing out that your snarky disbelief was flawed because it is possible for people to have made money. You're reply implied that I was misrepresenting gambling or didn't understand the simplicity of what we are talking about and you replied in a holier-than-thou manner to boot.

I advise you read what people are saying and think about more about how you come across before diving into an argument.

There's no accounting for scientists. They are bound to do something stupid at any given moment. Mathematicians, on the other hand, should never buy a lottery ticket. I know from experience because I bought a couple of lottery tickets. They were ten cents a piece, two for a quarter. I won the million dollar prize, a dollar a year for a million years. As you probably guessed, the prize money has ruined my marriage. I'm still stuck with the same woman.
 
  • #48
To me it's all about risk vs reward. The risk is very low since I'm only giving up about 3 bucks, but the reward is enormous. The chance is low that I'll win it big, but IF I do...hoo boy I am going to buy so many telescopes...

And, indeed, she claimed she leaves casinos as soon as she wins. This suggested to me she has a well-proven system that could potentially make her rich.

Wow, just writing to note that my post has sparked quite a lively discussion where almost nobody replied "But on average you lose!".
The more I think of it, I realize that the important question - if you are really in it for the chance of winning - is not what the expectation value is, but what is the probability of winning big. Being ridiculously low, as it is for lotteries, you can only justify what you do by saying that you do it for the thrill.

As a pension plan, it is obviously idiotic.

I gamble to have fun, or for the 1 in a million chance of winning big in the case of lottery tickets. That's it. I don't play "to win big", as it is very very unlikely. I have made money gambling, usually by simply getting lucky one night and leaving while I am a few hundred up. Of course, this is offset by the times that I have left with a total loss.

I don't know why that suggests that she has a well-proven system that could make her rich. Sounds to me like she's simply a little bit lucky, with enough smarts to leave while she's still up.

Just as a repetition:

Monique said:
I've often won with gambling, also at the roulette table. The trick is to realize it's going to be lost money and to start running the moment that you win.

I don't buy lottery tickets on a regular basis, since the chances of winning are so low, but sometimes it's worth the thrill of tempting luck.

Dickfore said:
So, do you lose sometimes?

Monique said:
Not more than I've won.

Dickfore said:
Wow, great! You must be a millionaire by now.

Monique said:
What kind of a remark is that?

So, the bolded words imply to me that she has a worked-out system, a trick if you will, that let's her win more than she loses in a repetitive fashion, since she claims to do it often.

Then, when I asked her if she is a millionaire, she started wondering why people ask her, and, of course, we had the knight in shining armor defend her honor.

The lynchpin is that you have to win first. If you don't win, you can't walk away with money. And winning doesn't usually mean win just once. If I'm playing roulette I can win a dozen times and lose twice but still be down depending on how I'm betting.

Honestly your statement Wow, great! You must be a millionaire by now. is extremely sarcastic. Is it any wonder you had the responses you had?

I tend to agree with you on this one.

It is, and it was intended to emphasize the absurdity that she wins more than she loses on a regular basis. Honestly, if I had found some scheme like that, I would be trying to get as much money as possible.

Why are you behaving so ignorantly? Yes, it's possible to win, yes it's possible to loose, yes, it's possible to play even.

Come on, have I said that I game on a regular basis? I said that when I gambled I've often won, for you to deny such a possibility is absurd.

And what exactly does this tautology have to do with the topic at hand?

No, you said I've often won at gambleing, even at the roulette table. To have won often, it is necessary to had played at least as often as having won. Also, you said that you won more than you lost. I find this statement highly improbable, and your further claims about initial probabilities and such made my suspicion even more founded. I suspect you are biased in remembering the times you won more vividly than the times you lost.

Did you keep track of your bets? Did you keep track of your wininings? Did you keep track of the times you had gambled and the total time spent?

It is very easy and uncomplicated: I have won more money than I lost.

Luck is a strange thing in my experience. Never had any luck in the national lottery, occasionally a break even but most of the time a waste of money. Well you buy the thrill of fantasy.

However on one of my assigments in the NATO we had a good multi-national social interaction and there was a weekly bunco-night. You just role dice and there is absolutely no decision to take. Pure chance. Just role, socialize and have fun. Eventually, we had no idea where to store all the useless stuff we won. It was just shameless, I hardly remember leaving without a price. Clearly far more than our fair share.

You do realize that for every game, there is a distribution of people who win more than they lose and people who lose more than they win? True, (assuming the probabilites are fair and not skewed due to cheating) the distribution is skewed so that the total money lost by the losers is more than the money won by winners, but there is someone somewhere that happens to have won more than they lost. Monique is claiming to be one of those people. Why is this so hard to believe?

Monique's "system" seems to be "quit while you're ahead". This means that, whenever you reach a point where you have won more money than you have lost, you stop playing.

I have been to a casino once in my life and decided to try the same strategy. After having gamboled with $3.00 (penny slot machines) I found I had won $3.34. There, I stopped playing.

It is not possible to get rich doing this. I think it is possible to win more in the long run than you lose, however. The next time I went to the casino my rule would be to put a limit on how much I was willing to lose. If I set that limit at 5 cents, I would stop playing as soon as I'd lost that amount. I would still be ahead 29 cents over all. If I continued with that limit on loss night after night I could go 5 more nights and still correctly say I had won more than I lost. When my profit was down to 4 cents, if it came to that without me winning again, I would have to quit gambling altogether but could still say I'd won more than I lost overall.

So, you can play several times, quite accurately claim you've won more than you lost, and still be far from rich.

All it would take is one big (or even moderately big) win to make this "system" plausible.

As far as playing lotto-type games: yes, when the jackpot gets large we start a pool here at work. I know the chance of winning big is vanishingly small. But it's worth the esprit de corps to put a couple dollars into the pot.

With the risk vs reward being the probability of a life changing event? Losing $3 is not a life changing event while winning the lottery is a life changing event. No risk; some small chance of reward.

Of course, one way to increase the chances of this being a life changing event is to turn every bit of assets you own into cash and go drop that on one roll of the roulette table. 100% guarantee of a life changing event - probably not the life changing event you were hoping for, though.

Risk and benefits just can't be measured linearly and I don't think the average net loss per dollar spent really says anything relevant unless the person is considering a career in playing slot machines.

In which case, the only questioning is which would happen first - go positively nuts from staring at a slot machine and pulling a lever or go broke. But I generally get bored very quickly by casino games - I just don't see whatever it is that can get some people addicted.

I did use to like horse racing when you could watch it live at a local track. That was more like watching and betting and cheering a sporting event and I could usually wind up a little ahead (you're competing against other bettors instead of the house). But that's no fun, so the last race I'd always bet whatever I had left on the longest shot. Who wants to go home and say they won $3.35? You want the big event - a payday at least over $100. And if you didn't go with all that much money in the first place, you've had a day of entertainment for a fixed cost - no chance of a negative life changing event.

Should a scientist never buy a lottery ticket?
not for monetary gain of course

but back in the 80's i bought a Florida Lotto ticket every week for a few months.
Three reasons:
1. I had just finished Carl Jung's "Synchronicity", and a friend had showed me the "I Ching"
2. I had a TI99 and was trying to improve my skill with Basic computer language.
3. I had because of some work i did come to realize the human eye and ear excel at recognizing patterns. A good ear can name the volinist and i double dog dare any spectrum analyzer to do that.

Back then you picked six of forty-nine numbers for Florida's lotto,

So i entered a year's worth of winning numbers into a 49 wide array
converted each to a 49 bit text string binary representation of the winning numbers by setting the six appropriate bits ,
printed the whole year out as text strings in both binary and hex format looking for a pattern,
looking for "Music of the Spheres" so to speak.
TI 99's basic math was 64 bit so it ran faster than one might expect of a $49 computer.

No pattern was apparent to me
so i wondered about other number bases
which led me into an interesting field,
irrational numbers and i bought a little book on them
but i was never smart enough to convert binary integers into base e or pi or Planck's constant.

So , as an engineer i bought some lottery tickets
and the payback was i learned to manipulate strings in Basic

plus an introduction to some far out math.
A couple years ago there was lots of stuff on 'net abut base e computers
but today i don't find any.


just my 2.718 cents worth..

No, but not because taking risks that you would lose more than you gain is wrong but because there are more likely and productive ways to make your desired millions.

Kant's categorical imperative dictates that it people ought to take risks because we have very limited intelligence and taking chances is often the best way to discover new things. If 1000 people blow their life savings on a white elephant and only one turns out to be a success then it is ultimately good because that one success will benefit 7 billion people and many billions who will yet to be, up until the point where it would have been disscovered anyway.

Probably because the numbers were decided by a monkey in a hat knocking around a hamster ball full of bingo balls...
