There is a relative high number of genuine scores with the score 0. When looking to these pictures there is not always a clear difference which could be an explanation for this score. Expanding the subject group might resolve this problem and give the possibility to draw conclusions on why this scores are 0. As stated in the results the long hair has one of the bigger influences. But it is also very difficult to separate different hairstyles. Hairstyles change overtime and even different hair types like curly or strait hair can have a big influence. Using different datasets can result in other interesting results. Where a uneven background could have such a large influence that the type of hair is not even significant anymore.
