Just saw this on Sİgnal vs. Noise and found it interesting:

The Guardian reports on an interesting study that suggests police should skip photofit composites and go with exaggerated caricatures of criminals instead.

A photorealistic sketch is an exercise in accuracy, but an exaggerated
caricature is an exercise in identity. Of course this is just one
study, but it’s an interesting look at what really matters to get a job
done.

We have been noticing at Mondus that people use exaggeration in their online social networking profiles, as well.  Perhaps profiles should not be exercises in accuracy, but exercises in efficiency.  If your profile gets you interacting with the people you’d like to connect with, it’s successful.
