		<description><![CDATA[The privacy discussions of today are in the warm, welcoming environment of a U.S.-centric Internet. 

There is constant, inexorable pressure by foreign governments to open up the Internet&#039;s plumbing. Why? Sovereignity, for one. While Iran and China are probably the most &quot;out there&quot; in terms of buying certain software packages that make it easier for them to portray their, ah, unique perspective via the Internet, their interests to control the message in the name of &#039;national security&#039; are mirrored by just about every government out there. 

The things that we think of as &quot;exciting&quot; and leading to &quot;greater autonomy&quot; may actually have a paradoxical, chilling effect. Within a day of the time you probably wrote this post, ICANN chief executive Rod Beckstrom set DNS down an path that separates the Internet as we know it -- ruled by English law, driven by the spirit of American entrepreneurism -- towards a world where there are multiple masters; where many can say &#039;no&#039; and precious few are in a position to say &#039;yes&#039;.

		<title>Comment on How to Design Survey Questions by David Schatsky</title>

		<description><![CDATA[Hi Jay,

Thanks for your reply with its valuable perspective on the practices of other syndicated research firms.  A couple of reactions:

&quot;Just a comment on hypothesis testing. In my experience as an analyst rarely were survey data designed this way&quot;
- At Jupiter, at least, it wasn&#039;t universally done nor was it rare. Hypothesis-driven design was our methodology and I believe we tended to get more usable data when a hypothesis was top of mind during design time.

&quot;Important hypotheses are often tested using archival data collected for non-research purposes.&quot;
- At Jupiter this happened to a limited degree because of infrequent use of historical data and very limited supplies of current-year data. In principal, every single survey question was tagged with one or more specific research reports (and associate key questions) it was supporting.

&quot;Often times assertions are made that cannot be reasonably supported by the available data.&quot;
- I would never knowingly publish research that made unsupported assertions. A sound research QA process ought to catch and prevent that from happening. Doubtless, the occasionally flimsy assertion will have slipped through the cracks, I suspect. I won&#039;t speak for the output of other research firms.

&quot;often syndicated research is opinion masquerading as fact&quot;
- Well, I&#039;d think that the data is the data. But the analysis is the analysis. And the assertions are another thing entirely. At client organizations, people in a variety of different roles with different skills might make use of syndicated research. To market researchers, or people with deep quantitative and technical skills, syndicated research may seem insufficiently rigorous. Meanwhile, to business decision makers, the same piece can seem overly freighted with numbers and stingy on business implications.

Just as it takes skills to design and conduct research, it takes skill to use it effectively. As you say, &quot;in the wrong hands can be used very poorly.&quot;

Thanks for writing.]]></description>

		<description><![CDATA[Nice post.  Just a comment on hypothesis testing.  In my experience as an analyst rarely were survey data designed this way.  But, strictly speaking that should not be a problem.  Important hypotheses are often tested using archival data collected for non-research purposes.  Since surveys are typically written to serve a broad program of research in syndicated research firms, they are rarely formulated with focused research questions in mind.  In practice,  hypotheses are used to motivate research topics after the data have been collected.  They are rarely used in the tradition of empirical research you suggest.  That is, questions designed to address specific propositions.  Most syndicated research firms also rarely use simple statistical tests to understand whether apparent patterns in the data are meaningful (both in the statistical sense and in the economic sense).  Many research outfits either completely ignore this part of empirical research or use margin-of-error heuristics.  Using simple statistical tests can help you get a lot of mileage out of small surveys, and is critical for determining how many observations you actually need to answer the questions posed.  Simple power calculations done in advance can also save a lot of money spent with research vendors.  Many syndicated research outfits also fail to use true panel data -- a missed opportunity.  Using a stable panel to form time-series cross-section data is a very useful way to really understand effects between individuals and within individuals over time.  And, it offers really simple strategies for testing the effects of major market changes over time (see difference in differences research designs for e.g.).  Often times assertions are made that cannot be reasonably supported by the available data.  Patterns can be very misleading without deeper consideration. I would guess that many causal claims made in syndicated research are subject to Simpson&#039;s paradox (there&#039;s probably a wiki on this and its worth reading) if given greater attention.  There is obviously a mountain of literature on research design, and much of the basics are used in sound practice....but, often syndicated research is opinion masquerading as fact. Data users beware.  Opinion has an important place in making strategic decisions and should not be under-valued while the application of quantitative research should not be over-valued since in the wrong hands can be used very poorly.]]></description>

		<description><![CDATA[There is no question that knowledge has its limits, and certainty, especially outside the realm of hard science, is a red flag. Expertise is no excuse for hubris.

I believe that in public policy, where the stakes can be very high and the impacts of decisions tend to be widely felt, I am more comfortable with a humble expert than his or her cocksure opposite.

		<description><![CDATA[I not sure that suspicion of economists/expertise is really the same as embracing gut instinct.  In fact, I think gut instinct is a strawman*.  Expertise of a sort will always be with us, as there will always be people inclined to focus deeply on particular things.  

What I do think is worth pursuing are ideas about the limitations knowledge.  This is particularly crucial in areas where the impacts of decisions, be they those of GW Bush or Ben Bernanke, are felt among many people.  In our deliberations about major issues, we should be deeply skeptical of presidents deeming themselves to be &quot;the decider&quot; or economists celebrating their role in creating &quot;The Great Moderation&quot;.  All of this is to say, these are always political/moral/philosophical questions.

*-I use strawman here since every Econ PhD seems to use it in their defense of their profession.  I think there has to be some class that teaches them to do that.  I also think economics can only use that argument against all critics if it is willing to disavow any claim of an orthodoxy.]]></description>
