I think it nicely shows that the concept of "intent" is problematic. Whether you "intend" to exhibit any behaviour can only be determined after you have exhibited that behaviour, which means it cannot meaningfully be claimed to precede the behaviour. A machine that can determine intent ahead of intended behaviour with 100% accuracy is therefore an impossibility.

This is strange.
I can intend to drink it, fully intending to drink it, and puking three hours after I drink it. People sincerely intend to do stuff all the time that they are reluctant or even afraid to carry out. Marriage for example. |

I tend to agree on the difficultly of creating puzzles based around knowing intent.
The puzzle tries to raise a question about knowledge of 'the truth' being a real good. Would the drinker be better off not knowing? If a person is better off not knowing, maybe the value of knowing something as it is, cannot be axiomatic. There are implications to accepting ignorance as a virtue that I tend to resist. I would be far more likely to accept that knowing 'true knowledge' of something was a 'real good', if not an axiom. Humm...

I don't need to drink toxin in order to win, which I already did. But suppose I will still drink it as evidence that my intent was true. All that says is that I'm skeptical of an intent detector and I want to prove my intent with evidence in case the eccentric billionaire changes his mind and tries to take my million back. It would be hard to prove I had no intention about drinking the toxin after I actually drank it, so that seems at least rational. |

This was dealt with extensively in my first year of law school under the umbrella title "inchoate offenses." Suffice to say that I know the answer - or, at least, the practical work-around that the law has devised. I'm not going to tell you, though, because I spent $100,000.00 and I'm not giving it away for free.

You would need to go ahead and drink the toxin anyways because it is the only way to really express that your intention was legitimate. It was in taking the easy way out (not taking the toxin because it was allowed) that would cause you to fail this test.

I agree with this assessment. You'd have to work it backwards, starting with drinking the toxin, which is the fuel for your intent to drink it. The last link in the chain to work backwards from is drinking it, not not drinking it, so you have to drink it.
Winning the money is not dependent on anything but your willingness to be ill for a day. If you wouldn't swap a day's health for a million, then you can't win this, even if you believe you don't actually have to drink the toxin. So, providing you actually drink it (and are not merely prepared to drink it), then you will win. |

If the intention detector is 100% correct, then you either cannot win the money, or you will drink the toxin. Otherwise, your intention is false, and the detector will know this.

I'm pretty sure there's a false dichotomy here. You may truly intend to drink the toxin at midnight, the detector confirms this and you get the million. At 12.01 you, acutely allergic to, say, nuts, unwittingly eat something with nuts in, your throat swells and you lapse into a coma, are carted off to hospital for emergency treatment which is successful, but takes 24 hours for you to recover consciousness. The noon deadline passes with no toxin administered and the million in your poke.
I can't see any of the rules being broken here. Loss Leader's "inchoate offense" provides the out, I believe. |

I think this is a variant on N****** 'paradox'.
To make the problem clearer, the money will be sent to your bank account 12 hours before you drink the poison or not all. What happens to you after this time does not effect the outcome. Suppose someone you know to be utterly truthful would come up to just before you drink the poison and say "Don't drink the poison, you got the money." or "Don't drink the poison, you've already failed the test." Regardless of what your intent was there is no point in drinking the poison at this point. However, after the intent test, even if no one trustworthy says anything to you, you still know that one of the above statements is true and there is no point in drinking the poison now. So do you decide to drink or not? |

It seems to me that one needs to do an awful lot of reading into to get this into the so-called experiment.
You need to enter the wonderful world of academic obscurantism that is way off the path of practical thinking. There is no puzzle. There is no paradox in the thought experiment. Did you promise you'd drink the poison? That might entail a moral issue. But that's not stipulated in the experiment. Gosh, this is like those silly "zombie" arguments we had going a while back. If you want an actual puzzle, play Sudoku. |

Ahh, I was going for Newcomb's paradox, which is a bit less silly.

I would win the money, and here's how I would do it.
I would immediately contact a friend, and draw up a contract that said, "If offered a chance to drink toxin X, I will give my friend one million dollars if I turn down the chance." In other words, to demonstrate that my intent is genuine, I will create a condition that makes it certain that there really is a penalty for failing to drink the toxin. Now, "intent" is not enough to win the money. I still have to do it, which would make my intent genuine. |

Here's what the law has to say on the subject:
Quite some time ago, the courts ran into the problem of intention. First of all, it is impossible to know what is in a person's mind. In fact, people can often have conflicting emotions. A lost wallet with a hundred dollars in it can cause a person quite the dillemna. Second, even if a person at one point intends to do a criminal act, if he changes his mind and decides not to why should we punnish him? After all, fear of punnishment may have been the motivating factor in which case the system worked and we should all be quite proud of him. The law has solved this by decreeing that intention alone will not be enough to prove a person's guilt of anything. What is needed is some sign that this person really would have committed the criminal act if given the chance. So the law requires some action towards the crime. If I want to kill my boss and I tell everybody I'm going to, I've done nothing illegal. If I go to the store and buy a shotgun legally, I've probably done nothing illegal. If I load the gun, I'm still OK. The moment I aim it at my boss, I've committed a crime. I've taken an action with no innocent explanation in furtherance of an illegal goal. That's the crime. This poison hypothetical is not unfamiliar to television viewers. It confronted a character on one of the most popular TV shows of its time. In an episode of Friends, Ross needed to prove how sorry he was to Rachel. She demanded, on Joey's reccomendation, that he drink a cup of fat. He promised to - that was not enough. He held the glass - that was not enough. He put it to his mouth - not enough. Not until the fat touched his lips was Rachel satisfied that his intentions were pure. Sadly, they broke up a little while later. Those worried about Ross and Rachel, though: |

Hmm.. I see that one of those conditions was "make no bets", which was probably intended to cover my contract as well.
One way or another, I would have to come up with some other reason to drink the toxin, otherwise, I would say that it's impossible to win. |

Of course it's possible to win. The contest relies on a device, and all devices can be manipulated.

Humm.
If the intent is to make this an argument about morality it must ignore a concept of mostly eastern philosophy that is often expressed as "no mind": It is possible to decide and act without moral attachment. We are being asked to ignore that and concede an assertion that morality must be part of this choice. This begs the question.

The purpose isn't to make it an argument about morality. It simply illustrates the changing nature of the thought experiment based on perception. If your world view is one where there are no moral ambiguities then there is no paradox. If morality doesn't enter the equation then there is.

If you wish to leave morality out of the experiment you are more than free to do so (assuming free will of course ). The thought experiment does not rely on morality. That is just another aspect and a practical one I might add for those who think in such absolutes to perhaps see things a bit differently.

The problem for me is that it embodies a rather outdated idea of the "self" as a unified thing rather than warring community of modules each pushing its own agenda.

It's been my experience that, if you really get down to it, people don't change their minds. They pay lip-service to an intention, maybe even delude themselves for a time - but if you really intend to get that paper done, you will. Unforeseen circumstances - like sudden floods, etc - are a different situation.
And for such a short-term intention - there isn't likely to be any unforeseeable circumstance to prevent you from taking this discomforting but otherwise harmless toxin. I'd do it in a heartbeat. |

Either you are psychic or you already have created the 100% accurate intention-reading machine. To say that someone never really intended something because they did not eventually do it is unfalsifiable.

But an intention - as someone else put it, a promise to self - to take an action is something that, if truly done, would preclude any reconsideration. In fact, it would be the primary deciding factor, if the intention were true.
"Well, I could change my mind now, since I already won the money; but I intended to take the toxin and I will follow through on my intention." Any other statement tells me the person had a false intention, which would be detected by the machine. Simple enough. |

That almost certainly says something about your personal ethics, and also about your personal definition of "intent." Neither of which generalize across the universe, unfortunately.
I think that the phrasing of "intention" as "a promise to self" is needlessly and divisively strong. Certainly no courtroom would use that strong a formulation in trying to decide whether or not the element of "intent" was there in a trial for attempted-whatever. The OED defines it much more simply and more lightly as akin to "wanting" or "goal" ("volition which one is minded to carry out"), which I think is a much more accurate statement of the meaning as it's generally used. There are lots of things which I am minded to do -- unless something else comes up, or I change my mind,.

I agree with that, Dr. Kitten.
That's basically the point I'm trying to get at - if an 'objective' intent detector existed, that implies that intention is something solid and detectable. As I understand the idea of 'intent', such a detector could not fail if it worked at all, and free will would be a demonstrable illusion as well. I could say I intended to drink the toxin - could even make myself believe it as well. But if I am aware that, after getting paid, I can just 'change my mind' and not drink it, then either I'm still going to drink the toxin, or my 'intention' to drink it was false anyway. The real case would be that I intended to fool the intent detector, then not drink the poison by 'changing my mind'. So what's the real intention, then? You have to take into account every factor in that decision process, to determine if the person ACTUALLY intended to drink the toxin. |

I still think you'reascribing a degree of unchangeability to "intent" that shouldn't be there.
A real-life counterexample : surrogate motherhood. I assume you're familiar with the practice of infertile couples asking a young woman to bear a child for them, usually via artificial insemination or in-vitro fertilization? Needless to say, the legal aspects of such an agreement can be .... complex, and I will defer to the actual members of the bar on the details. But one thing that's come out over and over in the court system is the tendency of many of the young women involved to change their minds and to refuse to hand over the child, even when the contract says that she must. Obviously, at the time she signed the surrogacy agreement, she "intended" to hand over the child an had no "intention" of keeping it, or she wouldn't have signed a contract that wouldn't let her do so. But somehow in the intervening months, she changed her mind (and I could go on in detail about pregnancy hormones and "maternal instinct" but won't), to the point that she is now willing to undertake expensive legal action to break a contract that -- under your analysis -- she shouldn't have signed in the first place. If you can change your mind in nine months, why not twenty-four hours? |
