This post must be related to the recent "How do you draw a circle?" [1] article. They used the term "southpaw", which I had never heard before.
EDIT: Strange, I definitely read the word "southpaw" somewhere in the last few days, and I remember learning that it was a term for left-handed people. Now I can't find it anywhere in the circle article, the HN comments [2], or the Reddit thread [3].
Little things like this really make me want to sign up for fetching.io again.
EDIT 2: Ahh, I found it! It was in a Quartz Daily Brief [4] news summary that I had skimmed earlier today:
> Left-handed people are more likely to be geniuses. The trait indicates greater connectivity between brain hemispheres, which may explain why southpaws seem to have an edge at math. ([5])
js2, I'd be really interested to know if that's why you posted this, or if it was just a coincidence.
