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?
Well, to be representative of humans, they need a sampling of it all, for better or for worse. That is a strength of humans: diversity in backgrounds, thoughts, experiences, strengths, weaknesses, and capable of working together regardless.
Is it? That seems like a bold statement with no other technological species to compare against.
Genetically, we’re actually a low-diversity species, because there was some serious bottlenecking in deep prehistory.
