Fruit Flies Show Spark of Free Will
Lucas123 writes "A study performed at the Free University Berlin on human free will has produced some unexpected results showing that fruit flies may have a spark of free will in their tiny brains." From the article: "Their behavior seemed to match up with a mathematical algorithm called Levy's distribution ... Future research delving further into free will could lead to more advanced robots, scientists added. The result, joked neurobiologist Björn Brembs from the Free University Berlin, could be "world robot domination."
I for one welcome our new cyborg fruit fly overlords!

Okay, I should know better than to divine meaning from a mass-media source, but I tried.
First, Levy's distribution is a, you know, distribution, not an algorithm. I guess it meant to say that the algorithm weights a factor by Levy's distribution.
Then, after going through about eight paragraphs to find out what the hell the experiment did that was so relevant, it still didn't make sense. What bothered me was that one of the scientists see "free will" as being "somewhere between" deterministic and random. Now, I'm all for treating properties as cardinal and a matter of degree. But isn't free will, by definition, BOTH non-random and non-deterministic? How can it fall on a spectrum between them?
And what about the experiment makes "free will in flies" the best explanation?
(Oh, and on a side note: please spare us the story about religion: not all religions endorse free will, and not all atheists reject it.)
Apology to Ubuntu forum.

If they've got free will, does that mean they can go to heaven or hell?
Not hard to imagine Fruit flies swarming over the Apple in the Garden of Eden, though they would probably have preferred a banana.
Wow! I've been /.ed. Well, I never... :-)
/. discussion, I think I've lost my free will. Now where did I put it? Anybody here seen it? Maybe these pesky flies stole it? :-)
Once I realized it, I felt so compelled... I, I just had to address the
Of course, our original study makes no mention of free will, it is not a scientific concept. However, spontaneity even in flies makes us ponder what, if anything, this might entail for our subjective experience of free will in a macrocosm we believe to be largely deterministic. Therefore we addressed the issue with an ironic question in our press release: "Do fruit flies have free will?"

Of course, the media will drop the question mark, because questions don't sell. Some journalists even told me their editors told them to emphasize the free will thing precisely for this reason. That's fine with me. The debate got re-ignited and that's a good thing, I believe. The discussion here shows that. You can see all the coverage and blogosphere discussion linked at:

Scientifically, the most important aspect (which understandably got a little buried by the media) is that we found evidence for a brain function which appears evolutionarily designed to always spontaneously vary ongoing behavior. There is tentative evidence that such a function may be very widespread in the animal kingdom, including humans. Why would all brains have this function? If this were indeed the case, we might have discovered the first evidence for something truly fundamental to our understanding of brains.
Take it easy folks,

Science is a lot like sex. Sometimes something useful comes of it, but that's not the reason we're doing it.
You were on a roll up to this point. But here you seem to be falling for a different brand of question begging: you are tacitly assuming that there is "a reason" for things to be the way they are. So far the best explanation IMHO is another tautology... Things are the way they are, because that's the way they are.
That's the gripe with science that rational religious people have (and yes, they do exist), science can conceivably tell you how the universe works but can't tell you WHY it works that way. To speculate on the motivation for things to be the way they are is outside of the realm of science. Some people dislike this and they look for explanations in meta(beyond) physics. So basically you have to big trends, either the universe "just happened" or it was somehow made. Science could tell you down to the very last quark how the universe works in either case, it doesn't matter to it whether something put it together like this or it was just a Big Freak Accident as long as there are strings of cause and effect leading from "A" to "B" to "C" and so forth.
Conceivably if the universe was made, and The Maker tweaked it at random here and there —i.e. by performing miracles— that would thwart science's efforts to explain things because it relies on repeatability and pattern-finding. But experience so far tell us that our reality has stable behavior that doesn't change in unpredictable ways. That doesn't rule out the possibility of a maker behind curtains, for all we know s/he/it may be tweaking the world and still staying within its rules. But science won't be able to distinguish intent from random accident because it operates from inside the environment and whether the "rules" were placed or they just sprung from nowhere, they still bind it.
