When I try to look up the question of why kids (often) don't like crusts, there is the occasional person that frames it as an "American" thing. Other disagree pointing out Brits, Europeans etc. also feel this way.
But is there any evidence that this varies by country, culture or nationality? If so why might this be -- differences in type of bread/baking styles?
I'm not sure if outside (ha!) the "rationalist sphere", other people have independently invented the phrase "outside view" or not but I feel there's some spillover of the term "outside view" with similarity to "outsiders' view" which I think is common enough in layperson speak.
An outsider's view (or third party view, attempt to be objective and look "outside" your current situation as an "other") as conceived of in daily life does have elements that are pointed at in this post for popular interpretations of outside view ("Bias correction, in others or in oneself", "Deference to wisdom of the many").
But it also could heavily involve the original meaning described and clarified in this post too of "Reference class forecasting" if outsiders can offer broader views by adding to the reference class.
For example in an argument when two people are fighting over (thing) say a married couple bickering or two friends whose relations have soured due to some problem, the two parties with vested interests may think their struggle is unique and particular, but a neutral third party or outsider can often (though not necessarily) have a better, objective view because they've also seen enough different fights over (thing) that the two involved have not seen before.
In particular, "boldness" and "daring" seem to me as if they have very little to do with nonconformity
So, for instance, you could be bold and risk-taking but doing so because you want to live up to a norm (or are heavily driven by chasing an ideal that's "conventional")?
For instance, a manly warrior taking risks to show off his manliness or lack of cowardice, or desire to fill the warrior role in his tribe. Would that count?
Interesting explanation, but does that hold for other foods -- do kids/adults that don't enjoy the crust because it's harder tend to also dislike other difficult-to-chew foods? Anything from jerky to raw vegetables? And those that do enjoy it, enjoy chewing other harder foods?
Clearly, there are lots of crunchy/chewy foods kids are willing to eat or at least are not stereotyped as off-putting the way bread crusts are for kids.
It'd be interesting to tease apart what is causing the dislike -- is it really texture, or taste or something else?
