I don't see the beginning of the thread for some reason so I'm not entirely sure what you are referring to (although I have a good guess). Might you be referring to James Coyne's recent commentary about Ellen Langer's research? If not, you might find his thoughts on the matter interesting (although I suspect you may have already seen this & that this is what you are referring to): http://www.sciencebasedmedicine.org/eminent-harvard-psychologist-mother-of-positive-psychology-new-age-quack/ Trent On Tue, Nov 18, 2014 at 2:55 PM, Stuart McKelvie <[email protected]<mailto:[email protected]>> wrote: Dear Tipsters, I had always regarded the two nursing home studies (experiments, actually) as interesting and have regularly reported them in my classes. The significant finding of different death rates in the follow-up study was of particularly attention-grabbing and almost too good to be true, but I had not seen any reason to doubt it, even though the sample size was small. I went back to these two papers to see if I could detect serious errors in methodology and statistics. Of course, if there was something important that was not reported, we would not know that. Based on this re-reading I still do not see any serious errors, although the data on multiple measures could have been treated with MANOVA rather than ANOVA. The authors also report various attempt to keep extraneous variables constant – e.g. raters being blind as to the condition in which people were. In addition, they express their own surprise at the death rate data and admit that not everything was known about the patients. Of course, the matter of replication remains. If this has not occurred, we do not know what the outcome would be. As I mentioned in an earlier post, there has been a failure to replicate the results of the exercise-as-placebo experiment. So, overall, I still think that the original experiments, as reported, offer interesting results. Have there been serious criticisms of them that I have missed?

This is so discouraging. Eye opening perhaps, but discouraging. I remember well the nursing home study and I always thought positively of it. I have two parents in their 90s and I know they are frustrated by their lack of independence and the loss of control over their lives. But as I reflect on all this I had to ask myself, "Why would I think that the participants in Langer's study would lead healthier, longer lives simply because of their ability to take care of a plant?" Given how complex humans are, and how complex life is, why would I think that a simple “intervention” like giving people control over a plant would have such powerful effects? Maybe because I wanted to believe…. As for this counterclockwise “study”…oh boy..at least it is indeed an excellent point about how eminence doesn’t necessarily mean credible. I am additionally discouraged because I recently finished reading a published article which appeared to have been carefully carried out (and which was filled with all manor of impressive advanced statistical techniques) but in the end all they really found were essentially correlations. I kept going back to my underlined sentences and I still couldn’t figure out why this study was important enough to publish. The hypotheses and the conclusions were “tortured” into giving up some kind of “significance”. I need some cheering up: can anyone point to a recently published article they think was interesting and credibly carried out? Michael Michael A.
