You can either get something that is representative, so the median, by choosing mid traits (mid spiritualistic, mid artistic, mid intro/extroverted, med IQ), or by choosing at random. Everything else would not be representative, and depending on your own traits, you would be biased - eg. non spiritualistic, non artistic, introverted, anxious, mid IQ, technology oriented, but also trans and depressed. Some of those I would obviously not see as an average trait, but being atheist and non-spiritualistic would definitely be on my list, despite not being the actual norm.
Idfk, for me almost everything with visible blue in it is blue.
