DY, it is tendentious to separate data from analysis as if there is no relationship. Of course I am familiar with Twain’s “Lies, Damned Lies, and Statistics” quote. Here he starts with the hypothesis that surveys are useless tools of the Liberal literati, and goes from there.
Criticizing (even irrelevantly and incorrectly, as he does) shabbos phone calls, is about data collection, not analysis.
In criticizing the questions that Federations supposedly tailor to their supposed anti-frum needs, he is talking about methodology, not analysis.
And the ironic part of all of this is that the survey results, which I have read, aren’t particularly harsh, and display a very wide range of rationales and information about the OTD phenomenon. I don’t know why he’s defensive about it in the first place.
