Constructing on latest advances in social cognition, we design an algorithm to routinely generate trustworthiness evaluations for the facial motion models (smile, eye brows, and many others.) of European portraits in giant historic databases.

Additional analyses recommend that this rise of trustworthiness shows is related to elevated dwelling requirements.
