>>13647761there may be some scientific truth to physiognomic principals, but it is smothered under much more substantial social/political dynamics. You can use any physical/biological/quantifiable feature to "predict" human qualities, but in a competitive social system, this prediction becomes deterministic (reified), rather than innately predictive, as it started.
Its the same problem with IQ tests, how the average seems to increase year after year. When measures become targets they cease to be good measures. This is an epistemological problem with human prediction/measurement.
