PsyBlog: Are Boys Better Than Girls At Maths?
There is a lot of research in this area going on right now. Apparently current studies are showing that math achievement is showing little to no difference between genders in primary or secondary. However they are still seeing vast disparities in certain curriculum areas (physics and chemistry in particular are mentioned).
While vast strides are being made to bring women up to the level of men, my prior argument stands - why? I'm all for equal opportunity, but you can have that very easily without all the excess baggage that Europeans tend to ignore anyway.
Here's a question, if women being underrepresented in science is such a disaster, what about the lack of men in education? Why aren't they working just as hard to eliminate the gender bias in the educational world.
More thoughts on recent data on math scores across genders here.

Global warming - revisiting the data
Nasa is out of line on global warming - Telegraph
Is all this accurate? If it is it does not paint a very flattering picture of James Hansen, nor does it reflect well on his rather public disregard and outright hostility towards anyone that has questioned his methods or asked to see the raw data.
This doesn't close the book on global warming by a long shot, but it does highlight one of the problems with the scientific community (or at least a problem with certain unscrupulous individuals within that community) - when you want to find data to support your position, you can find it, or in extreme cases manufacture or obfuscate data that support your position.
Fortunately this doesn't happen very often, but the problem of interpretation of data is still very much a partisan and perception-based activity.

Why Gender Does Matter
Why Gender Doesn't Matter | Psychology Today Blogs
The arguments made by Dr. Grewal (based on the study by Dr. Hyde) are typical of the "gender doesn't matter" crowd. The arguments put forth in the book she also references "Why Gender Matters" are based on a very different approach than statistical measurement.
The statistics of gender differences will always be trending toward the nihilistic. That's what statistics generally do, they move towards the mean the larger the population you pull from (and even more true when looked at longitudinally). Gender differences from a physiological standpoint are blindingly apparent. Genetically the differences are also simple to detect (if not blindingly apparent).
If (as with nearly any aspect of science) you have a philosophical ax to grind to prove your position, you will be able to find evidence that will support it. In the case of this study they find that statistically speaking the differences in very specific measures are small, so that in turn must support their world-view. However, what is more interesting to me is that the differences exist! Statistics can have the effect of making true impact seem smaller when done in particular ways - the fact that the difference in fact do exist makes it apparent that gender does matter. No matter how small (statistically) the differences are, they are there.
Personally I don't understand why anyone would want gender to be equalized - from either aspect. Why not celebrate the differences and use those differences to the advantage of either? The concept of being "fair" or making things more "equitable" seems to have a homogenizing effect that to me seems very boring. As with education, homogenization tends to look good on paper and it may even be appealing to specific individuals, but applied across a broad spectrum ultimately leaves more people unsatisfied than not (how's that for a double negative - look at me go!).
It is my opinion that gender not only does but should matter. Admittedly it is a conservative viewpoint - which is hardly surprising coming from me - but one that I nevertheless support.

Learning Requires Freedom
Learning Requires Freedom: Introduction to a New Blog about Play, Curiosity, and Education | Psychology Today Blogs
I love it - someone after my own heart. His comments on government restrictions on education are particularly nice to see and, in my opinion, accurate.
Children are consistently subjected to the "miniature adult" perception that many adults have. Adults cannot remember what it is like to think and act as a child, so it is assumed that what is good for an adult must be good for children, provided we're not expecting too much of them in certain domains of knowledge or experience.
It is a load of crap.
Children (as Piaget demonstrated and a viewpoint that has been amply supported by experimentation) are simply NOT adults. They don't even come close. They look like miniature adults, and they try to act like the adult models they're exposed to, but their cognitive processes simply are not the same.
I too wish that governing bodies of education would recognize that simple fact and back away from all the regulations.

Bottom line: removing the arts from education is a bad idea because the arts teach more than just "art" - they teach cognitive functions in ways that are unexpected.

Wow. An absolutely scathing rebuke of the public educational system. I don't agree with it 100% - home schooling simply wouldn't work for everyone - take single mothers who have to work to support their families as an example. Finding appropriate resources to help them out would prove difficult at best. So, public school definitely has a place, but certainly some of the criticisms are accurate - or at least they feel accurate.

This article goes directly back to the issues I just blogged about and policy issues in general. Policy is implemented on a general level with a general application, approach and understanding. On an individual level that kind of approach can make very little sense - and indeed can occasionally make absolutely no sense and, in fact, do more harm than good on an individual level despite the larger philosophical or supposed practical implications on a larger scale.

On innate talent
On innate talent Psychology Today Blogs
An interesting take on a familiar puzzle to motivational researchers. Is there such a thing as "natural" or "innate" ability, or is it all about motivation? Some research suggests that it is all about motivation, where other research suggests that "natural" ability plays a larger role.
There is a wonderful article on the two sides of the argument in Scientific American - from the August 2006 issue called "The Expert Mind" - terrific reading for a primer on the subject.
If, however, you're on the motivation side, here are two wonderful articles on how to:

Torn Between Left and Right
Torn Between Left and Right Psychology Today Blogs
I could have sworn I blogged about this earlier (from another source), but I can't find it so here it is again.
Basically, if thinking in abstract, people that think left (politically left, or liberal) but when presented with concrete examples (moving to an individual level) those same individuals tend to think right (politically right).
Therein lies the problem with public policy. While leftist (or liberal) ideals sound great when applied to very general scenarios, they tend to break down on closer examination at an individual level. And that is irrespective of which political leanings you may have - left or right. Policy in general is extremely difficult to manage because of the very group/individual conundrum mentioned here.
And it's not just a problem at the political/policy level. Most, if not all, research in the psychological fields are great at describing larger trends, but break down rather substantially when applied at an individual level.

Battering Bobo
Mind Hacks: Battering Bobo
The article provides a fantastic link to some original video that has Albert Bandura providing commentary on the famous study.
As the author alludes to, this is the experiment that still resides at the heart of the whole "video games make kids act violently" brouhaha that has become rather a hot topic (again) recently, so it is worth re-visiting.
I wonder if anyone has done a "virtual" bobo doll experiment? For example, have a video game that pounds bobo and then leave them alone with an actual bobo and see what happens.
I also wonder if anyone has done research on non-toy violence? Bobo is a toy, therefore it is possible that the violence perpetrated on it would be considered just fine, but otherwise inconceivable towards a real individual. Obviously violence towards real people couldn't be ethically modeled and observed, but the distinction between toy and reality would be something worth considering.

Wired for Belief?
Wired for Belief? « Neuroanthropology
Another article that tries to explain why we have "irrational" beliefs by tying those tendencies into an evolutionary framework. In other words (according to the article) belief in a supreme being (or any other type of non-scientific belief structure) has nothing to do with whether or not there is a supreme being - it's all because, evolutionarily speaking, it makes sense that our brains would interpret things we don't understand as having a supernatural origin.
No, really.
And......we'll just leave it at that.

An extremely misleading title - basically all they're saying is that we're becoming better at knowing which kind of cognitive processes activate different areas of the brain. Duh - anyone that's been paying attention to the flood of fMRI (and similar) studies when applied to cognitive functions could have told you that.
And that, my friends, is far, FAR from being able to "read" a mind. Heck, we can't even use this technology to reliably detect truth/falsehood in memory (contrary to popular opinion).
