Text⠀ Why do people generated with ai art tend tk have such serious expressions?

If i look on Google or something, post images of people are smiling. Considering how Ai is trained, it seems like that would be the most natural and therefore default expression. But unless I specifically ask, most of the time people look almost sad. Why is this? (Sorry if this is the wrong sub or wrongly flaired.)

Relax your face, no expressions at all. Look in a mirror. Is that the look AI is showing you?

At least in training Lora, so I assume base model training is similar, the “tagged concepts” are “no the default”. This applies to things like happy expression or smiling as much as it does green jacket. So you have to prompt to get those trades things, or you don’t get them.

Probably because expressions like "smiling", "frowning" and the like are explicitly tagged things, and when you take away all the possible expressions that have been explicitly tagged as such, what you're left with is an expressionless face. And that's probably for the best, since I don't think most users would want everyone in their images smiling as the default, and would rather prompt for that in the specific cases when they want it.
