Can you tell your left from your right?

Had a random conversation yesterday where a friend and I discovered that neither of us instinctively knew our left from our right. It was part of a conversation around neurodiversity and it got me wondering whether it’s just a random blip in our brains or part of something wider. So - do you just KNOW left from right or does it not come automatically? I also struggled at school with random bits of timetables (6/7/8s - could never remember the ones where the answers were somewhere between 40 and 50, but had absolutely no problem with maths overall and got straight As st GCSE. That’s not a boast, more just that it wasn’t linked to academic intelligence!). Am also left handed if that’s relevant (but still have to consciously think about which hand I write with if asked 🙈).

YABU- duh, obviously I can tell left from right 🙄
YANBU - No! I have to really think about which is which 🙈

Surely it’s just because you know that you’re sitting in the right hand side of the vehicle.

I don't believe that anyone ‘instinctively’ knows without thinking about it at least a little bit. Why would you?

Honestly, most of us don't have to think about it at all, any more than we have to think about the difference between up and down. People who do are in the minority. I know it can't be literally instinctive, in that we learnt it at some point, but that was so far back we don't remember. I mean, I don't remember being taught my name either. But I never have to think about it.

Depends how you define thinking about it.

If you feel like you don't think about it, it's because you are thinking about it at a subconscious level. Yes at some level your brain processes it, but you don't know it is processing it, you just know left and right.

If you think about it, have to hold thumb and forefinger up (or some other method), then your conscious processes are operating, which are much slower.

The east-west thing makes sense because if you view north as up as per convention, east and west are right and left so would presumably activate exactly the same neurological processes.

I'm very interested in psychology and neurological processes but very much as an amateur and suspect from what I do know of the science that the explanation I saw was a very simplistic version of the actual mechanisms.

A related thing is why satnavs and maps on phones etc. default to rotating to the direction of movement as opposed to north up as would be a normal map representation. It is because it is the method that is best overall solution for women and men - men would on average be marginally better off with north up, but women significantly benefit from rotation to the direction of travel (typically it becomes even harder to process whether an upcoming turn is left or right for women if not looking along the direction of travel).

I always turned the map round if we were travelling North to South.

Not so much if an issue now, with sat nav.

Tbh until your comment it hadnt occurred to me I sit on the right side of the car. But I do.

It might be more muscle memory than instinct. I just dont consciously think about it.

I mean in a car I dont have an awareness of thinking about which way is left. But outside of driving, I struggle to "know" left from right and the harder I try to think which way is left the longer it takes me to work it out

soupyspoon · 07/09/2025 20:17

OH doesnt know his right and left and its quite dangerous at times in the car. He is without doubt ND not diagnosed and very strong dyslexic traits.

Rowgtfc72 · 07/09/2025 20:25

I have to think about left and right, it's not instinctive. In my only 3 driving lessons I wrote L and R on my hands to be sure. The instructor looked terrified.
I tend to point rather than say left and right.
I can't do my 3s, 7s or 8 times table.
I get to and past muddled up when telling the time.
I don't walk in straight lines and drive dh up the wall
I have to turn a map in the direction of travel in order to read it.
I can't walk through a door frame without hitting it.
I also struggle with necessary ( cheers spell check) and sign.( cheers again)

Yanbu. I do talk about this with people and it’s more common than you would think but people are embarrassed to admit it if I don’t go first. It’s nothing to do with intelligence. What I’ve found helps is making a right angle with your thumb and forefinger - your left hand makes a ‘L’ 😁

For a long time the 'L' trick didn't help me. I'd just think 'but which way does the L go?'. It could be either.
When I was learning to write I would get letters round the wrong way, and even occasionally wrote whole paragraphs from right to left.

That worked itself out by 7 or so though, and I never struggled to read. Telling time was fine if the numbers were on the clock but impossible if just looking at the shape of the hands. Also fine now.

These days I think 'which way would I read that' and that mostly works, but recently got caught out because the gears on my bike went 5, 4, 3, 2, 1 rather than 1, 2, 3, 4, 5 and told my child to cycle on the wrong side of the path. 😣DP corrected.

Giving directions as navigator abroad similarly difficult, as I think of left as the side of the road we're on, rather than actual left.

Left handed, good academic results, professional qualification, no problems with tables.

As far as I know not ND, though, like many, I sometimes wonder.

FluffletheMeow · 07/09/2025 20:34

Necessary is one collar and two socks 🙂

Annotated1 · 07/09/2025 21:07

Ive also been confused by holding up my hand to make the L shape and figure which ‘L’ was the correct way round. I have to pretend to write something and then it’s ok 😂

jdb9803 · 07/09/2025 21:18

TeaAndCakeMakeThingsBetter · 07/09/2025 10:29

Ooooh this is so interesting that others struggled with the ‘middle’ times tables as well! Thought that was just me. I wonder if there’s some weird brain pathway that’s misfiring!

I would instantly know 7x6 but would have to think about 6x7

childofthe607080s · 07/09/2025 21:20

@Rowgtfc72ita been proven that people who turn the map make better navigators

Blipette · 07/09/2025 21:42

Sometimes, but sometimes I have to look at my hands to see which finger and thumb make the L 😂

deste · 07/09/2025 22:39

Same here, i have difficulty setting the table. I quite often have the cutlery mixed up.
i was aware one day that i gave directions to workmen that they had to turn left when they asked for directions. I told them to go into a no entry. Im not sure if they realised in time.

Ellmau · 07/09/2025 22:53

I can only do left and right when I physically draw a letter a in the air with my hands and realise which one is right. I can do north-south-west-east OK if I'm somewhere I know and can orient myself based on where the railway is. General sense of direction are awful though, I once got lost going round a corner and backtracking. Also poor sense of balance.

I can do the numbers OK though.

Can't tie a knot or thread a needle. And bad at recognising faces.

telephoneted · 07/09/2025 23:01

I’m left handed, so I think I instinctively know because of that

LilacPony · 07/09/2025 23:07

I can’t do it instinctively. I have to pretend I’m picking up a pen, I have to do the actual hand movements and pick up and write with an imaginary pen. Which ever hand goes for the imaginary pen is my right hand side. 😂

basinbasin · 07/09/2025 23:26

I don't understand the question 😆

Do you mean if someone says stand on your right you don't instinctively know which way that is?

MargaretThursday · 07/09/2025 23:35

No I really have to think hard, and even then sometimes get it wrong.
I'm ambidextrous though which doesn't help.

I do exactly this! I struggle massively with it and will confidently say the wrong one quite often. My daughter is the same and I've recently been taking her out for driving lessons, it's been interesting to say the least cos neither of us know which direction we're talking about 😂

Oooh this is so interesting! I was hoping someone might have a psychological explanation. That would make sense in terms of women having more cross- brain connections, but why is it only left/right or east/west that are the problem? Is it because the brain works across left and right? And like others have said, sometimes I mean one and say the other- why is it those specific words I have a problem with? Interesting to see that it’s far more common than I’d thought.

I always think with left and right (as opposed to up and down) it can switch, like if you look at a photo your right hand is on the left side of the image but up is still up. Another one that got me was if you say something is on your left but then you turn 180, it's now on your right, but again up is still up whichever way you turn.

CosyMintFish · 07/09/2025 10:18

I can’t.

When it’s mattered, I’ve written it on the backs of my hands. Also East and West.

A tip for East and West which my DM taught me was that Left pretty much rhymes with West.

Tintackedsea · 08/09/2025 00:37

Had to write L and R on my thumbs for my driving test. I mix up numbers a lot - 724 becomes 427 for example. Really struggled with times tables and number patterns like phone numbers or registration too. Maps are so confusing. On google maps I move in wrong direction all the time.

Talkingfrog · 08/09/2025 00:39

I am the only one in the house that doesn't get muddled with left and right.
The other two are both dyslexic.One is left handed. The other is predominantly right handed, but can do a few things with tthe left uite well too.
When going anywhere unfamiliar, I am tthe ne that navigates, otherwise I might get told to go left instead of right.
Once in the left of three lanes, indicating left, there isn't much I can do when I am told " not that left, the other left", other than turn left, and gind somewhere to turn around. When I navigate and say left and right, if needed I also say which exit on a roundabout, or to me/to you. 😃

@TeaAndCakeMakeThingsBetter
Hello OP - did you know this is one of the classic symptoms of Dyslexia?
And Dyslexia isn't all about difficulties with reading - that's only 1 of a list of symptoms, and it's possible to have Dyslexia yet still have learnt to read easily as a child.

That's interesting. DP really struggles with reading, and sometimes transposes numbers. I have always assumed he must be dyslexic, but he is in his mid-seventies, so dyslexia wasn't really a 'thing' when he was at school. He struggles with his left and right, despite me telling him the way to remember it is, "You write with your right hand".
