The much anticipated opening post

I promised to say something about who I am and what this blog is. So here it is.

As the box on the right reads, my name is Daphna and I am a PhD student in Tel-Aviv University. I plan my research to be about the skeptic – rationalist – humanist movement. Or science fans, or grassroots science communicators, or “geeks”. I am not sure which is the best term, so I’ll just use skeptics in this post at least.

I want to understand this movement. What it is about. Why people get involved with it. What it can – or can’t – do.

I have defined myself as a skeptic for several years and have been active with Israeli skepticism since 2010. A year ago, give or take, I started thinking it would be really interesting to talk to skeptics about skepticism. I had been doing long-form interviews on my podcast, and I found that it was something I enjoyed doing. Maybe that’s because I am kind of shy and in need of a good excuse to ask questions…

Anyway, I didn’t just want to get to know skeptics. I wanted to understand this world better through these conversations. Which, as I slowly realized, is a kind of research project. And thus the idea of going back to school to study skepticism formed.

As for the blog: I blog, of course, for the fame and fortune.

Well, not exactly, but I do want people in skepticism to know about what I do. I am still struggling with how to research something I feel part of. But I think the right thing to do is to let people in on what’s going on. Also, I hope my work will be interesting for people in skepticism, and it’s important for me to keep writing about it in a place that requires less social scientific lingo. In a way, it’s my own science communication project. That is, if you feel like calling what I do science…

I am just starting off now, both the academic work and this blog. In a way I invite you to join my thinking/learning process. I hope you enjoy it.

What’s a scientist?

I have just read Alice Bell’s paper about sciene bloggers. She mentions “science studies’ long-standing obsession with the way in which professional boundaries are formed and articulated through the popularization of science”. I didn’t know science studies were obsessed with that (I don’t know much about science studies anyway, I am afraid; I am going to have mend that), and it made me think.

November-14-2011-22-56-15-tumblrlqc5dwPyKI1qc62xio1400_thumbSkeptics are also obsessed with boundaries of science, but with the epistemological, not professional ones (epistemology is a word I feel free to use based on listening to 70+ episodes of Rationally Speaking). That is: what’s science and what’s pseudo-science, anti-science, bad science, woo or BS. This is the famous the Demarcation Problem.

But is it possible that all while reinforcing the epistemological boundaries of science, skeptics actually blur the social ones?

A case to the point: one of the leading figures in Israeli skepticism, arguably the most committed among us, a person who almost single-handedly made the Israel Skeptics Organization happen. She also gives talks about skepticism, and in her bio line for the talks she writes “a skeptic and a scientist”.

il_fullxfull.270580361I must confess that I feel uncomfortable with that. She is a person of many talents, including an undergraduate degree in the sciences, but that’s not enough to be a scientist, the way I understand the word. But my understanding is just that – my understanding. Clearly her understanding is different.

Another prominent Israeli skeptic defines himself more cautiously as “a science fan and an amateur scientist” (hmm… it sounds better in Hebrew). I say “cautiously” because talking about “amateur scientists” implicitly acknowledges the category of “professional scientists”. But while an “amateur scientist” isn’t a professional, she isn’t a layperson either, so boundaries do blur.

And what about myself? I am super cautious, and wouldn’t dare calling myself a scientist, with or without qualifiers. But I do after all allow myself to publicly critique the research methods of practicing (social) scientists, don’t I? Isn’t that boundary blurring, in practice if not by name?

What do you think? Do you agree about blurring the social border of science, or am I blowing things up? And if I don’t, doesn’t it clash with all this talk about what science is and isn’t?

P.S. – I ran this post by the people mentioned as I thought it would be fair to ask them before I publish what might be interprested as criticism. They both OKed it. They also both felt there was a problem here, and had already or will now change the way they describe themselves. Which makes the question even more complicated, I guess…

Economic inequality, the wrong way [my US elections post]

A research paper about economic inequality in America has been making the rounds: “Building a Better America - One Wealth Quintile at a Time” by Dan Ariely, behavioral economist and best selling author (Predictably Irrational), with economist Michael Norton.

I am going to tell you why, contrary to what Ariely claims, the paper doesn’t say that “Americans Want to Live in a Much More Equal Country (They Just Don't Realize It)”. And hopefully there’s a general point here.

The researchers asked Americans about the distribution of wealth in the US. The respondants grossly underestimated it. They said, for instance, that the two bottom quintiles (40%) possessed 9% of the total wealth, while top quintile possessed 59%. The correct numbers are 0.3% and 84% (!).

Is this shocking? Not really. Surely no one expects people to memorize macro-economic variables. Or do we expect them to “estimate” wealth distribution? based on what?

Incidentally, why did N&A asked about wealth, with income inequality much more on the public mind? Wealth is latent. If I own my apartment and my neighbor rents, I may be much wealthier than her, but no one can see it. Income is more visible - even where salaries are not openly discussed.

It’s possible that people had income in mind when answering about wealth. Maybe they didn’t realize the difference, or they used income as a proxy for wealth. It’s telling to compare the survey answers above to the US income distribution - 11% to the bottom 40%, 51% to the top 20% (Census Bureau, table H-3).

Yes, the survey meticulously explained what wealth was. But do you expect people to know the wealth distribution, if you need to tell them what wealth is?

This point safely nailed, let’s move on to the more juicy part, where people were asked to imagine joining a new nation. When they joined this nation, they were told, they “would be randomly assigned to a place … so you could end up anywhere in this distribution.” They were asked to choose wealth distribution for their new country. The result: among three alternatives – total equality, the current American state of affairs, and that of Sweden – Americans of all stripes wanted Sweden (!).

People also had to construct their ideal wealth distribution for the US. Again – everybody constructed a distribution more egalitarian than the current one. In fact, Ariely writes, “the ideal distribution … was dramatically more equal than exists anywhere in the world.” (!)

I refuse to be shocked, again. We saw people can’t estimate the wealth inequality numbers. I claimed they didn’t even quite grasp the concept. How then is it meaningful to ask them about their ideal distribution? How isn’t it just one big garbage-in-garbage-out?

And when Americans pick a distribution “dramatically more equal” than anywhere on the planet, doesn’t that imply precisely that they have no idea what those numbers mean?

Ariely writes that the study “avoid[s] hot-button terms, misconceptions and the level of wealth people currently have”. But preconception and personal stakes transform the academic to something that pertains on real life. And it’s real life people have opinions about.

That last point is my general one. Questionnaires are bound to take things out of context. Testifies every question you have ever wanted to tick with “it depends”. Questionnaires tend to assume people have opinions about everything, opinions that can fit into the available answers. Personal experience again tells us how wrong this is. People who use questionnaires says this can be fixed with good planning and statistical analysis. Well, if it can, “Building a Better America” isn’t a great example.

--

There’s more. The paper sometimes simply replaces one bias with another. This doesn’t have much to do with the point I wanted to make, but I can’t resist including it anyway. So as a compromise the type is small.

First, joining the society in a random economic position is supposed to take away incentive (Ariely compares it to blind wine tasting). That’s silly. If you are going to get a random piece of a pie, your rational choice would be an equal distribution, so that you will never end up with a small piece.

And does the size of the pie matter? the economic justification for inequality is that it encourages economic activity and growth. In the survey, all the pies are the same size, an implicit direction to ignore this argument. A similar point was made by a right-wing commentator in the National Review Online. Unlike that commentator, I share Ariely’s social-democratic sentiments. The trick is to be able to think critically no matter what your feelings about the results are.

Science, Storytelling

I’ll get to introducing myself and the blog, and apologizing for its name, etc. But I am going to kick off by telling about a science-themed storytelling evening I organized in Tel-Aviv.

The Story ColliderThe inspiration was The Story Collider. I have been listening to their podcast and I have enjoyed the stories. But I didn’t quite get it. Sure, there are “scientific” stories (David Dobb’s “Lost in your brain” is a favorite). But many are more like “the geologist & the bear”: I was doing science (looking at rocks in Alaska) – nothing much to tell about it – then something interesting, though mostly unrelated, happened (a bear). Well, when you are in a nature reserve in Alaska, you may happen on a bear. Why is it a science story? What’s the point?

President Shimon Peres in the Israel Storytellers Festival, October 2012And yet I went on and organized a science storytelling evening. The rational, frankly, was that it could be a storytelling event for people who don’t go to storytelling events. I mean, Everybody loves stories, yet, I’ve never even considered going to an annual storytelling festival held near Tel-Aviv. The re-runs from this festival, broadcast in wee hours, tend to have 3 grey-haired men with stories of glorious olden-times. Uncool.

Stories about science, on the other hand, that could be cool. That could bring in the hipster-ish geeks.

It turned out to be more complicated. The event was part of a meeting of Skeptics in the Pub Tel-Aviv. The attendance was lower than the usual and of those who did come many were new. Apparently people who think science stories are cool are not quite the normal SitP crowd.

People (including, to my horror!, the storytellers) kept referring to the stories as “talks”. Maybe they are used to the concept of a talk, what it is, what it is about. Stories are less obvious. This is a surprise, given that maxim that stories are somehow part of being human. It remains a point to explore.

My own story was an old family story about a scientist who fell in love with my grandmother. People said it was a good story about how even scientists can do crazy things out of love. I never knew that was what my story was about! Partly because - well, of course scientists would act crazy for love. What did you think they were, robots?

Which made me realize one type of value science stories have.

A scientistThere is an image of scientists as robots, or Spocks. But world-class physicists do get madly in love. And there is an image of scientists as pale, short-sighted nerds in white coats, but stories show how science could be a plain, old-fashioned adventure involving bears (or sharks). Science is thought of as this cold, inhuman process, but sometimes the scientific becomes deeply personal.

I suspect a major goal of the science communication project, both the official version and the grassroots, fandom version, is to re-brand science. Re-negotiate what it means to be a scientist or a person interested in science. Science storytelling is part of that.
