Lets say you get abducted by aliens.
They inform you that they want to make contact with human individuals, not the entire humanity. They have a limited telepathy and can “scan” for human mental traits like spiritualistic / non-spiritualistic, artistic / non-artistic, introverted / extroverted, anxious / chill, low / med / high IQ, technology oriented, business savvy, mathematically gifted, socially gifted, scientific, etc.
They want you to define traits that would make encounters go smoothly and be representative of humans.
Without knowing anything about those aliens or their interests. What is your answer?
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.
