  1. Contradiction on Forgetting May be Part of the Remembering Process · · Score: 3, Informative

    The primary study quoted supposedly shows less brain activity (in reality it shows less oxy/CO2 swapping, which is frequently mistaken for a measure of brain activity) when some memories are suppressed. Then they quote Anderson (U. of Oregon) who more properly identifies such suppression as active inhibition. Active inhibition is a form of activity. It should show up as a "lighting up" on the fMRI scan. In light of this, what the primary study shows is nothing. It's a failure to find active inhibition. Some results are notable by their absence. Saying your results show something when they in fact fail to is entirely different.

    "Recall" itself is a misleading term. We don't recall anything. We reconstruct. All memories are in some part false because they're generally fast-as-possible good-enough guesses by the brain. Keeping that in mind helps one understand that the creation of memories requires both active agglomeration of relevant components and active inhibition of the irrelevant. Once you grasp that, then you can try to figure out how the hell that lump of meat knows what's relevant and what's irrelevant when it's trying to put together what we perceive as memories before we get to perceive them, and you can then be as woefully ignorant about what's really going on as the people in the article as well as myself.

  2. Error: Subject Conformation on Online Shoppers are Willing to Pay More for Privacy · · Score: 1

    Fatal flaw: the study told the subjects how to act. They were confronted explicitly with the privacy "device" developed by the researcher. They knew what was being measured and allowed to behave freely. In such circumstances subjects consciously or otherwise will attempt to conform to the implied expectations of the researcher.

    MSNBC has an article on the same subject (http://redtape.msnbc.com/2007/06/price_of_privac. html#posts). Their poll is flawed for the same reason (it ends up measuring what people say they'll do or show others they'll do, not what they really do) but the article has some good observations.

  3. Transport THIS on Breakthrough Brings Star Trek Transporter Closer · · Score: 1

    The point that energy (ie. information; negentropy) was transmitted has been adequately made.

    The difference between that and transporting matter is a little problem in conversion. Luckily, we have the math.

    Take one red-shirted Ensign Fodder at 75 kg (~165 lbs). Take it in grams: 75000.

    Convert him to energy, which is measured in ergs. How many ergs? To get this, multiply the mass times the speed of light in a vacuum, in centimeters per second (29,979,245,800) squared (~9 x 10^20).

    75000 x (9*10^20) = 6.75 * 10^25 ergs. That's hard to chew. One erg is about the amount of energy expended by an ant doing a push up (http://www.astronomybuff.com/an-erg-is-an-ant-pus hup/).

    Convert that to something that seems a more reasonable to our minds. One megaton = 4.22 * 10^22 ergs. Thus, one Ensign Fodder converted to energy == 1600 megatons suddenly happening in the transporter room. Even in the best of circumstances, that 100% of said ergwise Ensign Fodder being moved to the landing coordinates before the energy gets released, and you have just transported between 80 and 160 Tunguska events, and your landing coordinates have just become a ground zero to rival the worst imaginings of any multiple MIRV targeted site in the minds of even the most hardened cold war strategic arms general.

    Where do you get this megatonnage? One assumes anti-matter conversion. At 43 megatons per kilogram on antimatter (plus matter, of course, but that's trivial), you're burning up 2 to 4 kg of antimatter just to use one Ensign Fodder to create a crater 4 to 8 times the size of the Arizona meteor crater (http://www.psrd.hawaii.edu/Dec97/impactBlast.html ) in the planet's surface. One would assume one would need to be pretty pissed at said planetary body (not to mention said Ensign) to blow a hole in it in this way. That antimatter represents a good piece of Enterprise's fuel. Keep in mind that 'burning' it in a controlled manner is going to require a piece of the output to keep it contained, and so the go-value of the fuel won't be near what the boom-value is when burned uncontrolled.

    The next time the Independent or any other media blurble plays pseudo-geek and insists on cramming in a sci-fi reference despite the fact that the people interviewed pretty much denied the comparison, ask them how big a hole in the ground was left by the test. If there isn't one, there was no matter conversion and so none transported.

    Which begs the question, how would we know if anyone ever managed to do this, unless someone were left to measure the crater? "Really big catastrophes don't leave anyone behind to tell the story." (Vernor Vinge: A Fire Upon The Deep).

What he said amounts to absolutely nothing except a red cape for those with more bull than brains. Does anyone seriously think he'd take retargetable weapons and hard code them for specific targets, and so lose the flexibility gained? He doesn't. They've always had targeting data available, just as we have, and either could use them on very short notice to target or retarget. Think about it for a second: he says they'll target specific sites in response to our missile defense technology. That doesn't even make sense. If he were serious he have said nothing about it.

Humans need to recognize quickly that there is a face and what information it's displaying far more than they need to differentiate one from another. Facial recognition software does just the opposite. Also, the software does the complete job every time. Humans only process as much as they need to in any given instance.

    2. The origin of the reward system is the substantia nigra. It is indeed in a primitive part of the brain. As mentioned in the article (re: Damasio et al) in humans, during testing on morality/altruism/etc. it acts on the ventromedial prefrontal cortex. This is the most recently developed part of the brain. Questions of morality, or even just confusing morality with brain science, requires this recent development.

    3. When part of the brain "activates" on a scan (both metabolic PET and hemodynamic MRI), that does not mean the system results activity. The scanner cannot differentiate between excitatory and inhibitory activations. In fact, "activation" is less interesting. 85% of the brain is excitatory and is spontaneously driven. The interesting stuff happens when spontaneous activity is inhibited.

    4. The dopamine "reward" system is in fact inhibitory. It inhibits random or undirected activity, and "sculpts out" desired activity from the possibilities. When it is activated, the dopamine system "lights up", but as it does it stops activity elsewhere.

The evidence they base their conclusions on -- the same conclusions that people parrot after not reading anything more than those conclusions -- is precisely zero. Their conclusions are their starting assumptions. Excuse the hell out of me for insisting on maintaining my position as an empirical scientist, but there's nothing NASA has published on the matter that shows anything like objective evidence. They keep hold to these issues in large part because as a highly visible publicly funded agency, the administrators are cowards when it comes to leading a human endeavor into the future. And rightly so. The congresscritters that write their checks are beholden to their constituents. Many of those would scream outrage at any hint of hanky panky or shenanigans and demand withdrawal of funds and recall of any astronauts, administrators and congresscritters who even appear to engage in (the logical flaw of) encouraging by not forbidding. Some of the tax payers, particularly the very vocal who are practised at pretending moral outrage in order to make up for the lack of true morals due to overabundance of prescribed beliefs, would make major media noise. the afrementioned administrators would feel it only just and proper to defend themselves (and their funding) in such a position. And they want to defend themselves less than anything. I'm almost certain there are internal NASA studies that provide realistic and rational conclusions and recommendations. They can't possibly have psychologists working for them on subjects like this only to have them be seen marching to the party's music. It's the complete lack of public release of such information that bothers me and leads me to these conclusions.
