name dropping

Can we do something about all the scientists who have decided to name drop themselves in the article?

nonsense

70-90% right handed, 10% lefthanded. 30% both. Shame.

at least say stas are divided. — Preceding unsigned comment added by Danja (talk • contribs) 21:22, 24 January 2015‎

/* Genetic factors */ deletion due to failed verification

This statement does not correlate with the citations provided.

"Other mechanisms may play a role in handedness, for example hormone signalling. Medland et al.[21] found a CAG repeat length variant in the androgen receptor gene (AR) that is positively correlated with left-handedness in females, and negatively correlated in males. This same variant is positively correlated with testosterone levels in males, and negatively correlated in females." This may help to explain why there are more left-handed men than women (around 12% in men versus 10% in women globally).[3] However, another study has found that this variant is instead associated with mixed-handedness in males (and not left-handedness), conflicting with the original results.[22]

One citation provided is a meta-study, that doesn't give explanation on why "left handedness" is more prevalent in males, just that it is more prevalent in males, the other citation provided states the exact opposite of the above text:

Behav Genet. 2005 Nov;35(6):735-44. Opposite effects of androgen receptor CAG repeat length on increased risk of left-handedness in males and females.

"Likelihood of left handedness increased in those individuals with variants of the androgen receptor associated with lower testosterone levels"

"thats left" means correct.Only 10 percent of exceptional creative genius in the world

Yes handiness means skilled. So for people who write with the left, using the right means wrong. With a likelihood to be more clumsy.

Still I like that many can use both efficiently.There are so many tasks that include both fine motor and gross motor skills that every one should have a different preference fro writing, chopping wood and use both for carrying things. The truly dumb would open a fridge door, take out the juice, put it on the counter and then closed the door using only one hand.Forcing people to convert caused enough loss, but to limit your self to the concept of being right handed or left-handed when we have two is truly disabling.

Mice; Keyboards and Mobile Phones

At time of writing, the article says nothing about mice, or keyboards or text messages on mobile phones? ----MountVic127 (talk) 03:57, 19 April 2024 (UTC)[reply]
