The Spottiswoode and May Criticism

James Spottiswoode and Ed May wrote a paper shortly after 9/11 criticising the GCP analysis. This is one of the most quoted criticisms of the Global Consciouness project, but there are some problems with it that should be noted. While they are smart and generally conscientious analysts, they made in this case some serious mistakes, especially of interpretation. Over the years we have occasionally talked about these issues, but without resolving our disagreement. Here I present some material from a discussion forum where in October, 2007, James once again made claims based on that earlier, flawed analysis. I include also some of the preceding comments in the discussion, in the usual email format with most recent posts first.

The post that started the thread was about otherwise unrelated claims various people have made that the stock market "predicted" the 9/11 disaster. But it also included a shot at the GCP which engendered substantial discussion:

Subject: Re: psi and 9/11?

I have some interest in checking this since, allegedly, the purchasing of puts on American Airlines was unprecedented in the days preceding 9/11. Do you have put volume for AA through that period and for a year or 2 before for stats? If so, I would happily run some analyses.

I personally thought that the original analysis with a peak on 9/2 was completely unconvincing but maybe if the data is weekly the 9/2 point represent the week leading to 9/11, rather than the preceding week. What exactly does the data point date mean?

In terms of psi I find fudging the time to be completely invalid. That is one reason I thought the GCP 9/11 result was so unconvincing. See: http://www.jsasoc.com/docs/Sep1101.pdf

On the other hand, for someone "in the know," buying puts on AA over the days leading up to 9/11 is exactly what you would expect to happen.

We begin with Roger Nelson's response on Oct 11 2007. If you are interested in reading the intervening discussion, the major posts are include below. It may be best to read the posts in order which means bottom to top (dates are provided for clarity).

James wrote, a few days ago: "In terms of psi I find fudging the time to be completely invalid. That is one reason I thought the GCP 9/11 result was so unconvincing. See: http://www.jsasoc.com/docs/Sep1101.pdf"

James labels this in a later post a "peremptory rejection" and hopes it will lead to some discussion. It has done the latter, and I like that. But this "peremptory rejection" is at least disingenuous, certainly misleading, and since James has been told many times how to distinguish the formal trials (and the formal specification for analysis of data on 9/11) from informal, it seems perfectly reasonable to call this "fudging the time" remark to be something like the damned lie linked to certain descriptions of statistics.

I understand perfectly well the demand for a hypothesis-based experiment any physicist could in principle repeat, but it is ridiculous to say the GCP does not present information that would in principle allow that. We are quite clear on what is done in formal tests of a local hypothesis for each event we select (see Dick Shoup's comment), and indeed it is possible for anyone who wants to do so to access the data to test his/her own local hypothesis. What apparently galls James and possibly others is the selection part -- how should we go about selecting an event? That is a tougher problem than physicists typically confront, to be sure. Just as James decided on a hunch to look at the times before earthquakes, we must decide on a hunch what kind of event is worth looking at in tests of possible correlated deviation in GCP data. Long since, at least for those of us much involved, the hunches have been educated. And we know (as others have commented) a great deal more by now about how the number of people and the distances between REGs affect the issues. And (though some of us, including, I think, Peter have not gotten there yet) we know about other factors on a different plane of measurement difficulty, such as how much compassion is evoked or involved, and what the valence of the emotion is.

These are hard matters to deal with, but psychologists and other social scientists have been working with some success for the last few decades to do some encoding and measurement in these dimensions. This is an area of great interest for me, and while it is not something most physicists are trained to think about, my guess is that little real progress in the psi business can be made if we allow ourselves to believe that, for example, a "psi field" (if there were to be such a thing) will be defined by a 1/r^2 rule. That kind of assumption is risky if not plain foolish. (Again someone else has so commented -- see York Dobyns' remarks.)

I am traveling, but have had a chance to read much of what has been said in this thread. No chance to respond in a deeply thoughtful way, but the "Treppenwoerter" I wanted to speak were ruining my sleep, so I decided to get a few lines into the discussion. Here are a couple more points:

I am not fishing. [This was one of James' critical claims about what the GCP does, and it appeared to be echoed by Peter Bancel, who does sophisticated analysis of GCP data. But see his comments.]

Peter may be [fishing], but the well defined "formal series" of tests constitute my effort to repeatedly test the hypothesis that there is correlation between deviations from random behavior in the data and selected global events. I really don't mind someone preferring to call this a conjecture, but I do mind the effort being rejected as fudging or data mining or fishing. I also am engaged in explorations, including some that are specifically intended to educate my "hunches" and ultimately to lead to better understanding of the psychological and social factors alluded to above. Something I have not discussed except when asked, is that my desire to learn is such that some of the events I choose to specify for the formal series are ones my "hunch" facility says are likely to be losers -- that is weak, null, or backwards, and hence likely to subtract from the accumulation of positive evidence for the general hypothesis/conjecture of a connection with consciousness. I have enough confidence by now in the data and in the evidence base that I feel it is OK use the formal structure (which allows unambiguous statistical evaluations) to learn something about valence, and compassion, etc., and, needless to say, N of engaged people.

Another point: We know that the average effect size in the formal tests is small, about Z = 0.33, and as Peter is careful to point out, this means that no individual event or local hypothesis test is adequate to tell us about the possible correlations. But to jump from that to the notion that it is all about averages is wasteful. September 11 2001 is not your average day -- in the world or in the GCP data. It is hard for me to credit the clarity of anyone who has actually looked at the GCP data for 9/11 and a sampling of other days who does not see structure in the data on that particular day. Just a glance at the autocorrelation of a simple device variance measure on 9/11 compared with 60 surrounding days (or 400 days) reveals a spectacular difference. It is even more difficult to understand how the fact that this comparison and several others that also show 9/11 to be unique in the database are "post hoc" rather than in service of an a priori hypothesis troubles any sophisticated observer. Deeper examination of data that a hunch suggests may be interesting must be done, and it is easy to discover that it usually is done in good science. Look at James and Ed's conclusion that the 5 sigma result in their big pre-stimulus response experiment is an experimenter effect (or DAT). If I heard it right, that is based entirely and exactly on post hoc analysis.

I am pleased that James provoked some discussion. Not sure there is any progress, but maybe these are steps in that direction.
