Familiar // Abstract

I arranged a subset of images on a spectrum from familiar to abstract. Familiar images were those that seemed to be more recognizable, while abstract ones depicted less easily interpreted images. 

Most users clearly tended towards recognizability of some sort, indicating that although they are willing to stretch the bounds of typical profile image, they do not stretch it so much that they lose coherency. Other than that, the types of content and personality of the user did not seem to affect familiarity that much.

*You may notice that not all profile images were used here. Once a clear trend was displayed towards familiarity, I chose to stop adding images since the point was made. Also to save my hand.
