Why do I have a moral duty to do wrong thing? Shouldn't I act in my own self interest to maximise the amount of money I make?

IIT proposes that consciousness is integrated information.

The key difference between a brain and the hard disk is the disk has no way of knowing what it is actually sensing. Brain can tell difference between many more sense and receive and use more forms of information. The camera is not conscious of the fact it sensing light and colour.

This article is a good introduction to the topic and the photodiode example in the paper is the simple version of your question http://www.biolbull.org/content/215/3/216.full

Thanks! The article was good. At this moment, I am... not convinced, but also not able to find an obvious error.

I participated in an economics experiment a few days ago, and one of the tasks was as follows. Choose one of the following gambles where each outcome has 50% probability Option 1: $4 definitely Option 2: $6 or $3 Option 3: $8 or $2 Option 4: $10 or $1 Option 5: $12 or $0

I choose option 5 as it has the highest expected value. Asymptotically this is the best option but for a single trial, is it still the best option?

That depends on the amount of background money and randomness you have. Although I can't really see any case where I wouldn't pick option five. Even if that's all the money I will ever have, my lifespan, and by extension my happiness, will be approximately linear with time. If you specify that I get that much money each day for the rest of my life, and that's all I get, then I'd go for something lower risk.

In general, picking the highest EV option makes sense, but in the context of what sounds like a stupid/lazy economics experiment, you have a moral duty to do the wrong thing. Perhaps you could have flipped a coin twice to choose among the first 4 options? That way you are providing crappy/useless data and they have to pay you for it!

Clearly option 5 has the higest mean outcome. If you value money linearly (that is, $12 is exactly 3 times as good as $4, and there's no special utility threshold along the way (or disutility at $0), it's the best option. For larger values, your value for money may be nonlinear (meaning: the difference between $0 and $50k may be much much larger than the difference between $500k and $550k to your happiness), and then you'll need to convert the payouts to subjective value before doing the calculation. Likewise if you're in a special circumstance where there's a threshold value that has special value to you - if you need $3 for bus fare home, then option 1 or 2 become much more attractive.

Here's one interesting way of viewing it that I once read:

Suppose that the option you chose, rather than being a single trial, were actually 1,000 trials. Then, risk averse or not, Option 5 is clearly the best approach. The only difficulty, then, is that we're considering a single trial in isolation. However, when you consider all such risks you might encounter in a long period of time (e.g. your life), then the situation becomes much closer to the 1,000 trial case, and so you should always take the highest expected value option (unless the amounts involved are absolutely huge, as others have pointed out).

As a poker player, the idea we always batted back and forth was that Expected Value doesn't change over shorter sample sizes, including a single trial. However you may have a risk of ruin or some external factor (like if you're poor and given the option of being handed $1,000,000 or flipping a coin to win $2,000,001). Barring that, if you're only interested in maximizing your result, you should follow EV. Even in a single trial.

Technically, it depends on your utility function. However, even without knowing your utility function, I can say that for such a low amount of money, your utility function is very close to linear, and option 5 is the best.

That depends on your utility function, specifically your risk tolerance. If you're risk-neutral, option 5 has the highest value, otherwise it depends.

IIT is provides a mathematical approach to measuring consciousness. It is not crazy, and has a significant number of good papers on the topic. It is human-independent

I don't understand it, but from reading the wikipedia summary it seems to me it measures a complexity of the system. A complexity is not necessarily consciousness. According to this theory, what is the key difference between a human brain, and... let's say a hard disk of the same capacity, connected to a high-resolution camera? Let's assume that the data from the camera are being written in real time to pseudo-random parts of the hard disk. The pseudo-random parts are chosen by calculating a checksum of the whole hard disk. This system obviously is not conscious, but seems complex enough.

I used Matlab for most of my programming. From what I have read (and seen), Matlab is the most used software for Computational Neuroscience. Almost all of the researchers who used any programming used Matlab, which a few people using C.

Thanks Am in the middle of writing up generalised proof of what I have done.

Work I did was mainly concerned with calculating integrated information for simple neuronal systems.

If I get some time, I could write up my result if people are interested

I am interested. What software did you use? I am trying to learn NEURON but it feels like Fortran and I have trouble navigating around the cobwebs.

I'm an undergraduate student, and I recently completed a holiday research project in computational neuroscience. During the project I found some interesting properties about connection properties in matrices which may not be a currently known.

Original research? CONGRATU-FREAKIN-LATIONS! Assuming, of course, that the whole things ends up being something cool.

Think it is really good using maths like this in the real world to improve skills.

I would presume what assume that arrival time would follow a normal distribution and be slanted further to the right (As there will be a minimum time to get somewhere, but no maximum time taken value that occurs) so not sure whether using the percentages is necessary.

Agree that this post should be on the main page.

I just finished reading about game theory which I found interesting.

Thanks for the welcome and for the links

Hi everyone, I am a 19 year old undergraduate science student majoring in statistics living in Australia. For fun I play chess and flute which I am quite mediocre at but find them both stimulating and challenging. I am always trying to improve myself in one way or another, whether it be learning or practicing skills.

I have an academic interest in maths, statistics and biology and would eventually want to be a biostatistician. I was originally seen as academically gifted, however after years of not working hard, I am trying to regain my academic vigor and ... (read more)

Hi, welcome to Less Wrong ! For things that you should read, I can give you three very classical (for LW) hints : 1. The book Goedel, Escher, Bach: an Eternal Golden Braid by Douglas Hofstadter. 2. Read the Sequences, they are really worth it. 3. The Less Wrong list (started by lukeprog, expanded by others) of the best textbooks on every subject
