Table 1.
Linear and quadratic relationships between IQ and perceived intelligence.
Figure 2.
Shape regression on perceived intelligence in men represented by thin-plate spline deformation grids showing differences in facial shape between faces with attributed high intelligence (upper left) and low intelligence (upper right) compared to an average configuration in the middle.
The lower panel shows composite images of 40 men photographs unwarped to the fixed landmark configuration predicted by shape regression (each composite corresponds to a particular TPS grid above). The predictions are not magnified by any factor and match the observed range.
Figure 3.
Visualizations of shape regression on perceived intelligence in women by thin-plate spline deformation grids illustrating shape differences between faces with attributed high intelligence (upper left) and low intelligence (upper right) compared to an average configuration in the middle.
The lower panel shows composite images of 40 women photographs unwarped to the fixed landmark configuration predicted by shape regression (each composite corresponds to a particular TPS grid above). The predictions match the observed range.
