Intentional choices during data set collation (to some degree 'emergent intention' due to aggregate preference). Search for 'boring realism' to find people working in other regions of latent space, e.g. this LORA: https://civitai.com/models/310571/boring-reality https://civitai.com/models/310571/boring-reality .
