Why do humans shake their heads to say no and nod their head to say yes?
>>
ITT OP has aspergers and tries to understand basic social cues
>>
>>12746510
Same reason autists like you are making these shitty threads; it's a previously established form of communication in certain cultures.
>>
When people didn't want something (like rape) they'd flail around and be chaotic. Shaking left to right is wider space used to signal no, while nodding is more reciprocative, ala no visual space of struggle, or at least not as much as shaking your head no.
>>
It takes less energy to move horizontal then vertical. Dealing with the average shitty human requires alot of headshaking.

when you nod, you look to the ground, and therefore you show submission
shaking head is similar to turning your back when attempting to run from predator

>Charles Darwin believes that this has to do with our primitive instincts and our nursing habits. When babies seek food they tend to lean their head forward in search of their mother’s breast. However, when they are not hungry, they shake their head from shoulder to shoulder trying to avoid the breast. This instinct continues into our life and that’s why we nod for yes and shake our heads for no.
>We need to clarify here that, even though this explanation makes sense, it’s nothing more than a theory. Yet, it’s a theory that most scientists seem to agree and it’s even backed up by the fact that people who are born deaf and/or blind will use the same gesture.

Not always, Indians do that weird shake thing with their head that looks like no when they mean yes.
>>
>>12746843
The indians wobble. It's not the same at all as the shaking op means
>>
>>12746881
I was implying that it's cultural.
>>
>>12746890
Then use a relevant example to back your claim
>>
>>12746510
because that's what became a consensus.

it was different in many cultures, but either the habit, or the culture itself is being eroded away
>>
>>12746894
I did, the indians and their wobble as you call it.
>>
>>12746901
Yhe wobbling does not mean no or yes. It is a way of smiling and showing that you are friendly.
>>
>>12746909
I was always told it meant yes, or agreeing with something.
>>
>>12746931
I just looked it up and it seems we're both right

>>
my mother's culture involves tilting the head up to say no (similar to what one would do while saying "what up nigga")
>>
>>12746510
in some cultures it's the other way around
>>
>>12746510
Me and most people I know shake heads for 'yes'.
