1+1 = 2

2/2+2/2 = 2

Sqrt(2+2) = 2

The internal experience can be very different despite having outwards similar expressions like shared preferences.

Why the differences would cancel out wouldn't necessarily be easy to explain, and sure it implies big differences are rare, but it's not impossible. Especially because we already know of many existing biological differences which still produce similar outcomes (in part due to redundancies) like in chemical balances and protein expressions, very commonly seen in differences in the gastric system

Just look at how associations between color and genders differ between cultures and change over time. Those differences absolutely exists, you're just not seeing it because you're not the target audience

I didn't say I was opposed to the idea or that I was discounting it out of hand. I simply said I was skeptical (unwilling to believe something just because someone says so) and mentioned a way to think through it scientifically. Then You kind of bombarded me with a lot of claims and anecdotes.... Eek. Hold your fire lol

Those are all compelling things you list and it piques my curiosity further. But these things aren't rock solid evidence. Sure it's possible. But not very convincing. We can do better. So yeah, I'm curious to tease out what color associations are learned versus hardwired.

"What you have seen" never makes for unassailable evidence on its own. That's because you, like every other one of us humans, is affected by myriad cognitive biases that can skew your conclusions. (Which is how we got superstitions and old wives tales)

Also, it almost sounds like your argument is that the only way for these associations to occur is through being taught directly and explicitly. But there are other ways to learn things. Kids pick up on all kinds of unspoken things. When going, they often look to their parents for their reaction to some things. They learn a considerable amount of language without being explicitly taught. Musical associations happen without explicit teaching and that definitely varies by culture.

One can just seek evidence to support their conclusion and ignore all the other possible causes or counter examples or whatever else.

For example, cool light (by this you mean light on the blue end) means focus and warm light (on the red end) means relax. Hardwiring is one explanation. But simple learned associations could be another.

Assuming it is true, perhaps orange / yellow / red tints make us relaxed because of associations with sunsets and candlelight. Or something along those lines. Would humana who grew up with a star producing a different light spectrum have a different interpretation? Can people be trained with different associations?

The premise itself has to be tested as well. Is it truly Universal across many cultures? How many cultures have you proven this to hold for? And how did you prove it? By asking? Or by sound experiments? Were those experiments duplicated by others?

Oh also you are unlikely to remember much of anything prior to the age of 3 (give or take). So maybe your parents did have those conversations but at a very young age.

Maybe studies have been done about a lot of these things. I would be curious to see them. But now I'm tired and need to turn my brain off.
