“Wizard of Oz” science at it’s best (don’t look behind the curtain, just be in awe of the results).

[...] In 2005, I tried to get the NSF to intervene and require Jacoby to archive his data completely. They refused. [...]

The drug trial analogy is incomplete. Jacoby clearly states that the 26 patients should not be heard from again.

Dr. McIntyre will have fully arrived when he receives correspondence that begins, “Steve, you ignorant slut…”

Of Jacoby et al. maybe we should say they are “omission oriented”.

From Jacoby’s response to you in the mission oriented link, “A lesser amount of good data is better without a copious amount of poor data stirred in.” This is true, but to paraphrase Bill Clinton, it depends on your definition of good data. I could understand it if his description of bad data included things like tree rot or whatever. But reading his full response, he is clearly filtering the data by the signal he sees, not the physical quality of the sample. ” Is there a common low-frequency signal among the trees? At a good temperature- sensitive site with good trees, there is.” This clearly biases his results.

Of course, this still begs the whole question of how you can extract a temperature signal from tree ring widths. The width of a ring depends on at least five variables, temperature, water, sunlight, CO2, and soil fertility but the width only provides a single equation. Basic math requires four more equations to solve for all five unknowns. What are the other independent measurements that will provide them?

Oh well, Semper Fi

Has the selective archiving itself distorted the record? After all, Jacoby has said that he is “mission-oriented”.

Let me guess. The goal of the “mission” has not been archived either.
