I would probably believe that if we weren't talking about software.

But software is, what, less than a century old? What possible evolutionary differences could have risen in that time frame?

I mean, the number zero is very unintuitive and the ancient Romans/greeks/chinese/whatever didn't discover it, despite the fact all evidence shows they were very smart in many things.

Yet you want me to believe that men understand that arrays are zero based better than women.

Apply that to any software principle.
