Handedness Bias

I'm left-handed, and I very explicity associated goodness with the left side as a kid. I thought I was being contrarian.

Here is a PDF download of the paper. (Found on the author's website.)

As a left-handed person, I can definitely confirm I've encountered handedness bias plenty of times in my life.

Just like with other "defaults" in things like race and sexual orientation, right-handed people typically don't think of themselves as having a certain handedness until it's explicitly pointed out.

I had been under the impression that the associations went the other way - that the Latin Dexter came from the Indo-European as did the Latin Sinestra. From those, we derived the association of the right hand with dexterity (so a person with 2 right hands is ambidextrous whereas a person with 2 left feet is clumsy) and the sneaky connotations of "sinister" (as you watch the person's right hand to ensure he will not attack you; a sinister person might stab with the left hand by surprise).

a new study (unfortunately behind a paywall... I wanted to see the methodology)

PM me for a copy of the article.

When I learned that Dexter and Sinister were greek words for Right and Left, respectively,

I believe you mean Latin words.

was told that it came from shield formations, and how the person on your left was a leech for using your shield protection, and the one on your right was your protector.

I was told it had to do with the left side being considered unlucky when performing auguries.
