What the world thinks spacecraft scientists/engineers do…

18 11 2014

Well, ramping up to the birth of our second child, (daughter Sloane on 08/05/14!), I’ve been completely absorbed by family by night and the incredible clip at work at Bigelow Aerospace by day.  -And amidst it all, I’ll admit that there is a visceral seduction in the elbow-grease-saturated chaos.

So, with this in mind, during one of my recent sleepless expanses I had the midnight inspiration to create a “What the World Thinks” meme.  It targets (with a little wry self-awareness) the increasing number of us toiling to break open spaceflight in the 21st Century the way pioneers did so for aviation in the early 20th:

The plural of “anecdote” is not “data”

The title of this post is tongue-in-cheek, but it makes an important point.  Just because many people believe, assert, or convey something does not immediately graduate whatever they report to become scientifically-reliable or even scientifically-useful.

This is actually symptomatic of a larger cultural issue here in the US.  Frankly, the dichotomy of what people choose to believe when it comes to personal testimony versus hard, scientific data in our society amazes me.  -And not in a good way.

There are numerous instances where hard-and-fast data hasn’t convinced a jury (or social group) of the reality the data demonstrates, and conversely, there are numerous examples of personal testimony that would easily have a jury condemn a suspect to death that would never stand up under scientific peer-review.

The simple reality is that people at-large simply seem to trust one-another more than (or in spite of the lack of) the presence of verifiable, hard data.  With, in many instances, grave consequences.

So, how have we arrived here?

Science as the most successful “reality tool” ever invented

How can this be?  How, in a world so clearly affected, governed, and reliant on the fact that scientific inquiry is the most reliable means to establish what is real and what is not, is there so much skepticism toward data, science, and scientists?

  • Don’t believe me about the success of science?  Look at everything, from the performance of the thousands of controlled explosions under the hood of your car to the molecular processing running the electronics of the iPhone in your pocket.  From landing probes on other worlds to controlling nuclear reactions with finesse to generate power.  From predicting the behavior of atoms in a lab to predicting the astronomical curvature of light halfway across the universe – the simple fact is that science is the best tool to understand reality – discriminate what is real from what is not – ever conceived by humankind.  If scientific data or the scientific process were inherently unreliable, then these achievements would be plainly impossible.  We would simply not be able to master reality in the way that we have using the scientific method if it didn’t always work.  (Left to ourselves and our naturally-unscientific methods of investigating the world, we can come to believe that dances influence the weather.  That earthquakes are a result of hedonism.  That illness is a result of possession by evil spirits.  You see the point.)

To many, it seems that “data” is a mysterious, possibly corruptible thing; that magician-scientists are able to distort it to “prove” anything.  That’s not the worst of it.  It also seems that scientists themselves are often placed in a different camp from the rest: Unconvinced by tearful assertions or compelling testimony, they are seen as aloof, cold… inhuman, even.

This conception of the scientist is something I’d like to explore, and I think it all begins with a single statement:  None of us likes to believe that we, as humans, are as fallible as we are.  So, what makes a scientist different?

Scientists recognize that we, humans, are terrible scientific instruments.

We are.  We’re awful.  Primarily, our data-recording mechanism (memory) is inherently flawed, governed by perception, emotion, expectation, bias, and it changes over time.  Further, there’s no way to do a direct download from memory to verify what a person is saying is an accurate description of their memories… or worse, if what they say is even true at all.  We also make connections that simply aren’t there, unable to discriminate coincidence from cause-and-effect.

This is why scientists rely on instruments that are not corrupted by feelings, fear, or excitement.  The colder and more calculating the instrument, the better the data it collects and records.  Even with these technically “unbiased” instruments, scientists subject to these flaws are still in the loop, which is why all ultimately-respectable data and analysis is brought before a group of other scientists to review (peer-review) to help ensure that the scientist has not unwittingly corrupted his own data.

All this because humans are terrible scientific instruments.

Meanwhile, despite these rather damning flaws, non-scientists seem to believe that they (and other people) are, in effect, excellent scientific instruments.  Human testimony is amongst the most effective tools to convince a jury of peers.  With all respect, putting a hand on a holy book and conveying a sense of sincerity (even if manufactured) has a way of graduating the “data” a human being reports to a plateau above actual data that can be scientifically verified, ignoring the fact that memories can be wrong(!).

Further, the validity of scientific data is often secondary to whether or not the scientist delivering the data “seems” credible, ignoring the fact that the data and data collection process can be assessed on its own merits.

Quite a disconnect.

What can we do to rectify the disconnect?

I’ve been thinking about this quite a while, and aside from training everyone in society to be a scientist, (which not everyone wants to become,) the only solution I see is to improve public relations.  Science is essentially failing a PR war, one waged both intentionally and unintentionally by those unsettled by a purely clinical view of the universe.

We need help to convince people that scientists are specialists in understanding how to collect good data and how to effectively wield data to construct a reliable, useful view of the universe.

  • NOTE: We can choose to believe any view of the universe we please, but choosing for instance to believe that offering a sacrifice to Zeus every spring will keep floods at bay is not a reliable view of the universe.  It will still flood no matter if I make an offering or not.  I may, in turn, assert that Zeus is fickle as an explanation, but then my view becomes neither a reliable nor particularly useful one.

We need more scientist heroes in our social dialogue.  Instead of having scientists always be the “dangerous ones who have gone too far” in our films and television shows, they should be portrayed as they are – venturing into the unknown that terrifies many of us in order to help us all better understand and (ultimately) prosper in our universe.

Having “mad” scientists all-too-frequently portrayed as antagonists – heedless, obsessive, or impious –  breeds a deep-seated distrust of science that is propagating through the entire social mind.

The truth is, I believe the sooner people understand that the plural of “anecdote” is not “data” – that even if millions of people believe in or even attest to something, (whether it be a flat Earth, astrology, UFOs-as-aliens, miracles, or that vaccines cause autism,) their cumulative belief doesn’t make their claims scientifically true or even scientifically useful – the sooner scientists will find the support they need for doing all the things we want to do: Cure cancer, create clean, powerful sources of energy, travel between stars, etc.

Food for thought!

Optical illusions to keep Astronauts sane?

DUS Architects, a public architecture firm out of Amsterdam, have recently premiered a public art piece called, “Unlimited Urban Woods.”  It’s essentially a forest-in-a-box.  With strategically-placed mirrors, the effect of “true” space – of standing in a vast, ordered orchard of trees – is apparently uncanny.

While intended to provide residents of dense urban areas an easy way to (at least psychologically) feel like they can escape the “urban jungle,” another practical use immediately came to my mind.  There are environments far more cramped and limiting than even the densest centers of glass, steel, and concrete.

For long-term space exploration missions, might something like this be far more effective than “virtual reality,” which forces you to look at some kind of electronic screen and shatters your brain’s acceptance of the illusion?  The trade-off is, of course, space.  One can’t fit a room like this inside a hard drive.  But perhaps it would be worth it?

Something to think about.
