Photo selection study reveals we don't look like we think we look

Results of the study show that the unfamiliar participants chose a different set of ‘good likeness’ images  compared to those that people had selected of themselves. Surprisingly, the images selected by strangers also led to better performance on the online face matching test. The size of the advantage in other-selection over self-selection was quite large – self-selected images were matched seven per cent less accurately compared to other-selected images.

Dr White said: “It seems counter-intuitive that strangers who saw the photo of someone’s face for less than a minute were more reliable at judging likeness. However, although we live with our own face day-to-day, it appears that knowledge of one’s own appearance comes at a cost. Existing memory representations interfere with our ability to choose images that are good representations or faithfully depict our current appearance.

“Interestingly we also noted there were better results when people were smiling in the photos. It is interesting that current passport guidelines prohibit smiling in photographs because this ‘distorts the normal facial features’. Given that faces are generally pictured smiling, and these images are rated as being more like familiar faces, it may be beneficial to permit expression in passport photographs.” Read more at ScienceDaily.com.
