'''Physiognomy''' is the former art and now science of deducing the predominant temper and other characteristic qualities of the mind from the outward appearance, especially from the features of the face, possibly including expression and movement across a brief amount of time.<ref>https://www.sciencedirect.com/science/article/pii/0304418188900024</ref> | '''Physiognomy''' is the former art and now science of deducing the predominant temper and other characteristic qualities of the mind from the outward appearance, especially from the features of the face, possibly including expression and movement across a brief amount of time.<ref>https://www.sciencedirect.com/science/article/pii/0304418188900024</ref> | ||
Physiognomy has gotten out of fashion due to its pseudoscientific history. With the machine learning hype, the field has regained some recognition, e.g. machine learning was used to detect peoples individual's behavioral tendencies via facial analysis, however it remains unclear whether the software can produce above-chance results based on facial or contextual cues. | Physiognomy has gotten out of fashion due to its pseudoscientific history.

More tangible results were also found as described below, but none of them have effect sizes large enough that one could assume them to be generally and reliably noticeable. In academic terms none of them have a correlation range of R=0.40+. However, proponents of modern physiognomy argue that making decisions on the basis even a small correlation is than doing so based on no information, and that the chances of making a good prediction increase as certain traits stack on top of each other. | |||
