The Skeptical UFO Investigator, Part 1.

This post is a companion to the talk I gave at Balticon 47, and is for people who would rather not watch the video, or would like more more details not in the video.

I've been investigating UFOs for over a year now, and plan to continue. Rather than explain exactly why this is, I am going to try and show you, one bit at a time. Much of the interest is driven by the human element, but perhaps not all of it.

As I have explained before, I don't know whether the Earth has ever been visited by non human intelligences from elsewhere, and I think it's highly unlikely that anyone else does either. I am skeptical we would know it when such an encounter was happening, though right in front of us. Our perceptions of such events would be fragmentary and distorted, and we would likely interpret them as magic, or supernatural.

Encounters of that very sort have been recorded all through human history, and continue to this day. Puzzling, often frightening, and frequently life changing events take place every day. Many of these, it turns out, are due to known bugs in the human perceptual and conceptual machinery, and others are merely hoaxes. UFO investigation has a more than 60 year history, and the truth continues to elude. I want to know why this is.

Let's go and have a look, I say, and let's see for ourselves what is going on.  Woody Allen once famously said that 80 percent of life is just showing up.  Let's show up where the saucers are seen and look for whatever patterns are there.

What's not wrong with the ETH

Gort is not pleased with us
OK, I just got through slamming the ETH to the deck, and I have it in a sleeper hold, waiting for it to go limp.  Why would I defend it?

Recall that my main problem with the Extraterrestrial Hypothesis (ETH) is the "Hypothesis" part.  It's not so much the answers it offers, but that it fails to ask useful questions that we can answer with real data.  However, I feel that I must also address some the attacks the ETH has unjustly suffered, as well as some of the false distinctions it is included in.

The so-called Extraterrestrial Hypothesis

Dr. Susan Blackmore is a little weird and more that a little smart.  She received the first ever British PhD in parapsychology, and believed in Tarot reading, out of body experiences, and psychic powers.  She was sure she could prove the existence of psychic abilities to even the most die-hard skeptics by amassing methodologically bulletproof evidence from a wide variety of experiments in clairvoyance and precognition, i.e. psi.   At the time, the whole field of parapsychology felt they were on the verge of breaking through to mainstream acceptance.

After a grueling series of consistently negative results, Blackmore began to be troubled by the definition of psi.  Psi was defined as whatever is causing psi experimental results to deviate from pure chance.  That is what psi isn't, but what is it?  Strengthening the methodologies made the signal drop down into the noise.  After repeated failures and not being able to define what to really test for, Blackmore soured on the very concept of psi and turned her research focus on to other things.

When it comes to UFOs, there is a shopworn old meme lying around frequently known as the Extraterrestrial Hypothesis (ETH for short).  It still attracts both derision and True Belief.  The ETH can be summed up simply as: some fraction (usually quoted at around 10%) of UFO reports are the result of something intelligently controlled that is not from Earth.

Do you see the problem?  It's analogous to the negative definition of psi.  By asserting that some UFOs - the otherwise hard to explain ones - are craft from outer space, we are really just stating what they are not - they are not ours.  But what ARE they?  A good hypothesis tells us where to look, and what information we can use to test the hypothesis.  The so-called ETH does not do that.  It's not a hypothesis!

Since aliens are very likely queerer than we can imagine, an alien spacecraft could be anything, and we would very likely not be able to perceive or describe it completely or accurately.  I won't address here the problem of the sparse, uneven quality of UFO data, or the thorny question of what phenomena to include, but even if we had terrifically good data, we still have no bonafide hypothesis to test it against.  "Not from here" doesn't fit the bill, and at this point, we don't know where to turn.  What happens in practice is that each of us invents our own private mental model of a single human-like alien race and wonder why UFOs don't behave that way.

Is there hope for the old ETH?  Not as such, but I believe it will have better successors. I do hope for really high quality hypotheses about the nature and behavior of alien intelligent life that we can really use.  The study of alien life, especially intelligent life, is pre-paradigmatic right now and starved of hard data.  We're going to need lots more information, and not much of it will be about UFOs (although I hope I am wrong).  The new emerging science of astrobiology will probably tell us much more about the constraints on development of intelligent species than any of our deeply flawed perceptions and memories of things we are unlikely to understand at all.

Nearly all hypotheses we develop about alien intelligences are likely to be wrong. Wrong, but the work of proving them wrong will lead us places we can't see at all right now.
