Amusingly this is actually a problem with the ML model (Probably? Not totally what percentage of under-paid human annotators would classify image 1 as not a gun.)

nope that's not how this works. it's not like the training data contains tons of handheld thermometer pics that are getting mislabeled, it's far more likely that due to training data biases the model has builtin associations between dark skin + guns.https://twitter.com/bjnagel/status/1245300089226174465 …
stephanie added,
I just mean that whenever a supervised learning model forecast disagrees with what a training label would hypothetically be then it's a model error, because it's learning an association of "dark skin->guns" that doesn't generalize outside the training set.
yeah i see how it's distinct from the amazon example below but i'd argue it's still a training set issue. can't say if the model is overfitting here — maybe it's learning everything it's fed at the correct level but w/o data bias we wouldn't have told it to learn this at all
either way models and their training data are inextricable from each other and u gotta check both to make sure they make sense
