SUMMARY

The discussion centers on the concept of handedness, specifically whether individuals can be neither right-handed nor left-handed. Participants explore the definitions of ambidexterity and cross-dominance, with examples such as Gerald Ford, who was left-handed while seated and right-handed while standing. Statistics indicate that approximately 1 in 10 people are left-handed, 1 in 100 are ambidextrous, and 1 in 100 exhibit cross-dominance. The conversation also touches on the complexities of handedness in various tasks, revealing the diversity of human motor skills.

PREREQUISITES
  • Understanding of ambidexterity and cross-dominance
  • Familiarity with basic statistics related to handedness
  • Knowledge of human motor skills and their variations
  • Awareness of cultural references related to handedness
NEXT STEPS
  • Research the neurological basis of handedness and ambidexterity
  • Explore studies on cross-dominance and its implications in sports
  • Investigate the impact of handedness on learning and cognitive abilities
  • Examine cultural attitudes towards left-handedness and ambidexterity
USEFUL FOR

This discussion is beneficial for psychologists, educators, sports coaches, and anyone interested in the complexities of human motor skills and the implications of handedness in various contexts.

Yes. I see. But that is for right angle turns only (that's "right" as in 90 degrees ; not right versus left for direction or handedness.)
As a city driver of 40+ years, it never occurred to me that there was any ambiguity in my clever saying.

No wonder it never got the appreciative nods I expected.

You're overthinking this. The "lefts" in what Dave said, "Three lefts make a right" are by implication 90° angles. If someone tells you that you need to drive 5 blocks and then turn left, it would be very unusual to interpret this to not mean 90° to the left.

Nor did I, but I doubt that it is "your" saying.

I've said this to @fresh_42 also, this is what happens when a seemingly innocuous question falls into the hands of a mathematician!

I came up with it on my own, I've never heard anyone else say it, though that's no guarantee someone else didnt invent it elsewhen.

Here are some possible alternatives:

  • right handed, not right hand
  • left handed, no left hand

there as also some people who are right handed for some things and left handed for others (throws right, bats left)
I gotta hand it to you... you came up with all the possibilities.

Do you just mean the use of the Space Bar and Shift Key? Or do you have something else in mind?

After all, we all have to use our left hand for Carriage Return. :wink:

There's lots of little things. Since I've always been left-handed, it's actually difficult to say what's harder for me than for you. (Took me into my adulthood before I learned that scissors don't raise welts on the hands of right-handers.)

  • Some applications use the two Ctrl keys differently. To operate the correct one, I have to cross my arms.
  • The touchpad on my laptop is shifted toward the left. I disabled it completely for a while, so I wouldn't keep scrolling the cursor while I'm typing.
  • The mouse buttons are the wrong way.

There is a config setting on you PC to swap the mouse buttons...

...using the NumPad should be easier for right-handed people. But spacebar? Right or left thumb - even I as a pretty much right handed person do it both ways. Where's the difficulty / difference?

Inspect carefully, it turns out there are two versions of left handed scissors.

Right handed scissors are assembled with the blade that is on top of the work positioned to the right during use. That allows you do see exactly where you are cutting.

Some left handed scissors just change the handles for a more comfortable fit without changing the blade overlap. This positions the top blade to block your view of the cut line. o0)

I hear that is rather annoying for lefties.

It's worse than that. It often won't cut because the angle is wrong. It just twists the paper.

I am right handed. I play guitar right handed but I play drums left handed. Trying to do either vice versa results in a sonic mess or personal body damage.

Same as me but I am left handed.
I write left (hence lefty), use a mouse, play pool hold a fork and drum that way.
Guitar right, badminton, cricket.
I play chess left handed, seems odd but I just tried it. Right hand on the table and move the piece with my left.
I am right footed (football not bass drum)
Not surprising I am at times completely baffled by the universe and everything in it.

I feel this is still reinforcing archaic binary stereotypes.You clearly have a hand-centric bias.

What about handed-fluid?
And why limit everyone to just two?

I don't like octopi. Not their fault, but when I'm skimming along the bottom free diving and all of a sudden a rock turns into an octopus with tentacles darting out at me and ink in the water, that is very startling for somebody not carrying any extra air!

And just to pull this OT discussion back to OP relevance, has anybody ever done a study on the handedness of octopi? That would be fascinating, IMO... Still 80/20 do you think?

Interesting, thanks!

Unlike in humans, this handedness is split more or less 50-50, rather than being biased towards right-handers. But it does seem to show why the many-limbed creatures go to the trouble of choosing a favourite.

I would rather have it on the left side of the keyboard, even if I am right handed.

If I use right handed scissors in my left had, they do not cut.
Something to do with keeping the blades tight against one another.
the left hand pushes them apart a little bit.

I don't get these left/tight handed references to sports or instruments.

Is the 'better' hand to be the upper or lower grip on a bat, or rather the left or right side of the pitcher when the batter steps up to the plate, or on which 'side' of the rink the hockey player is on when looking from his own goal.
Should the 'better' hand be strumming or playing the chords.
These are would just consider conventions that have developed and continued on.

Holding a tennis racket, or kicking a field goal - that makes sense.

Knitting - maybe that is a left or right handed activity, but no one talks about that. :mad:
( By the way I haven't knitted since grade 3 when we made those rope things from thread and a old spool. )
Knitters UNITE - are you a left or right handed knitter.

No it is not convention. Have you never played squash, tennis or badminton?
Never held a guitar?
One way feels 'wrong' and the other way feels natural.
As wrong and as natural as writing with your right or left.

One handed actions - definitely a handedness to them.
Batting - convention as both hands are used - where does it say the left or right hand should be above the other on the bat? In fact, a left handed batter has his right eye closer to the pitch, so he should really be a right eye handed batter.

I bat right handed, but play hockey left handed, and both feel natural, but where is the logic in naming one stance over the other.

Ok I get you now. Yes that is convention. How did the nomenclature arise?
My guess is a bunch of guys are doing something right handed because that is the norm. One guy is doing it different because he is left handed so that is the left handed position.
No one says Jan Ackerman is right handed he just plays.
EVERYONE noticed Jimi was a leftie, it looks odd.

An example. I went to drum clinic for schools when I was about 14. I was the only leftie for a snare session of about 10 or so kids and I was outed.
I was quite embarrassed because he said I should learn to right handed and would be an inconvenience in an orchestra. How would that work if I was the only leftie violinist?
I actually tried it and it felt awful so I switched back and put my foot down. I am playing left and my teacher who was a jazz drummer thought I played well.
So, the right way and the wrong way! The odd way is left by default because of the numbers.
