The selection process is clearly imprecise in the case of the self-assessed traits, because two quartiles should always contain half of the samples. With the exception of EXT(S), the selected number of users is much bigger than 150, while it is perfectly balances balanced  on the attributed traits. We do not know if this affects the training of the classifiers. Overall, the resulting classes have a balanced number of users, so no classifier should be overtly biased towards one class.
