Faception’s theory of facial personality profiling is supported by two genetic research observations: DNA affects personality, and DNA determines facial features. Linking these two observations lead the company to infer that personality can be identified in facial features since both are products of genetic expression.
The accuracy of this inference is yet to be determined but … AI technology itself is idiosyncratic. Machine learning algorithms learn from the data they’re given – and this data can can cause them to learn things in error.
