1 How to Recognize Considerate ET Marc Kuchner NASA Goddard Space Flight Center thanks to K. Denning, L. Mix, T. Bania, W. Sullivan, D. Brin, S. Shostak, G. Consolmagno

2 humans & ETI Stephen Hawking’s ETI Marc Kuchner Ozma 50 workshop ethical scale

3 humans good ETI bad ETI An alternative to Hawking. Marc Kuchner Ozma 50 workshop ethical scale

4 considerate speciesist racist family-ist selfish Whom do you consider when you make ethical decisions? Marc Kuchner Ozma 50 workshop e.g. Peter Singer Practical Ethics

5 humans good ETI bad ETI altruistic considerate speciesist racist caring for one’s family selfish An alternative to Hawking. Marc Kuchner Ozma 50 workshop ethical scale

6 r-selection: evolution with unlimited resources Large numbers of offspring, most die young! Rats, Insects. k-selection: evolution with limited resources. Small numbers of offspring, care for one’s young. Whales, elephants. Marc Kuchner Ozma 50 workshop

7 humans good ETI bad ETI altruistic considerate speciesist racist caring for one’s family selfish An alternative to Hawking. Marc Kuchner Ozma 50 workshop k-selection ethical scale

8 Green Beard Genes* Natural selection favors genes whose phenotypes promote their replication (e.g. Richard Dawkins: The Selfish Gene). E.g. gene in Fireant queens Look for ETI that are similar to us, so they might interpret us as being genetically similar to themselves. (*thanks to Lucas, ~last night,s cocktail party) Marc Kuchner Ozma 50 workshop

9 humans good ETI bad ETI altruistic considerate speciesist racist caring for one’s family selfish An alternative to Hawking. Marc Kuchner Ozma 50 workshop phenotype resemblance k-selection ethical scale

10 humans good ETI bad ETI altruistic considerate speciesist racist caring for one’s family selfish An alternative to Hawking. Marc Kuchner Ozma 50 workshop phenotype resemblance courtship behavior k-selection ethical scale

11 1)send a probe first---not their own kind 2)display some phenotypic resemblance to humans 3)engage in courtship behaviours. E.g. send gifts, be willing to take it slow. Considerate ETI will: for safety, we need to see all three

12 If you shout in the jungle you might meet at tiger. But if you shout in the city, you might hail a cab. Marc Kuchner Ozma 50 workshop Let’s take the time to find out where we are.
