Here's the problem with your reasoning:

In fact, most credible scientific research is available in the Internet.

Can you provide a web link for this?

MariaE:

"Most journals may be behind a paywall, but abstracts are usually not. A mention of what differences you had in mind would have been better, and a link to a review paper showing that between sex differences are higher than within sex variability would be a plus.

So you want others to do your research for you? Instead of informing one's self on a topic you just mimic the author of this article and say "nuh-uh, prove it!" and then when the person responds you say "nuh-uh, prove it!" then the person provides additional evidence and you say "nuh-uh, prove it" then the . . . wait, haven't we been here before? Yes, that's right, it's called the one way street. What good is it argue a topic with someone when they don't even have grasp of the basics? Who wants to spend their time explaining basic economics, physics, biology, neuroscience or whatever, when the antagonist is just going to say "nuh-uh, prove it!"

The Internet is not a source of credible scientific research. Getting something published on the internet does not make something credible. If something has only been published onthe internet, as opposed to reprinted, it's probably a good bet that it was rejected for wider publication due to lack of merit.

It is a physiological fact that male and femal brains are different, just as it is a physiological fact that male and female bodies - of which the brain is a part of - are different. I would list some of these differences, which can be found in any biopsychology 101 book, but what's the point when I know what the response will be (Nuh-uh, can you link to your proof?)
