  2. What are the Consequences of Detection? Notes before even starting to answer the question... ----------------------------------------------------------------------------------------------------------------------- 1) It depends. I have to say that. I’m an anthropologist. 2) Consequences for whom? Can break this down in many ways, but the first division is probably: invested scientists, or other people? 3) Generally, Life will be what we make of it. In most detection scenarios, the vast majority of people will be dealing not with extraterrestrial life itself, but with human perceptions and representations of that alien life. Data could be nigh-irrelevant.

  3. What are the Consequences of Detection? Depends on... ---------------------------------------------------------------------------------------------------------- 4) What kind of detection? • radio detection of ‘overheard’ traffic • radio or optical detection of beacons • signatures of astro-engineering • probes in our neighbourhood • evidence of past visitation, perhaps very long ago - durable signatures could include nuclear waste, large scale geoengineering, biotechnology, artifacts or messages (e.g. genetic insertions), any signature of artificiality • a naturally-occurring second sample of life: ‘second genesis’ / Life 2.0, ‘weird life’, or shadow biosphere on Earth - Paul Davies, 2010, “Footprints of Alien Technology”

  4. What are the Consequences of Detection? Depends on... ----------------------------------------------------------------------------------------------------------------------- 5) Verifiability / confirmation controversial/contested vs. definite 6) Significance of signal Rio Scale variables, also decipherability, content, comprehensibility 7) What is it? (Can we tell?) Biological or postbiological? 8) Is it interactive? How close, how active? 9) Is it volitional? Does it want something?

  5. What are the Consequences of Detection? Depends on... ----------------------------------------------------------------------------------------------------------------------- 10) Is it useful? Political, military, scientific, or commercial relevance? 11) Social context at the time 12) Consequences for whom, exactly, and on what timeline?

  6. What are the Consequences of Detection? A Question About the Question, and A Question About Answering the Question ----------------------------------------------------------------------------------------------------------------------- • What is our goal in asking the question? What do we want to know, and why? Are we seeking control over the cascade of events? Do we want to not be surprised? Do we want to ensure that we’ve done our duty in thinking ahead? • What are the consequences of ... thinking about the consequences of a detection? Are some kinds of thinking ahead counter-productive? Which kinds of thinking are most helpful?

  8. “The psychology of transcending here and now” - 1 People start from the 'here and now', and they use the same mental machinery to think about things distant from themselves in space, in time, social organization, or hypotheticality. Might explain why speculations about ‘long long ago’ are a lot like speculations about ‘far far away’.

  9. “The psychology of transcending here and now” - 2 The further away something is from people (doesn't matter whether the dimension is space, time, social organization or hypotheticality), the more abstract their thinking gets. Might explain why it takes all kinds of cognitive strategies and training to be more specific about distant things.
