saying it is wrong, because there is plenty of evidence to support the

I kid you not.

I am in full agreement on that… sadly, we have a (US) culture that invalidates
intellectual curiosity in favor of sensationalism and truthiness.

Mike,
I know it's pretty hard to resist the temptation to make scatological jokes
about this, but believe me, people with severe Crohn's and ulcerative
colitis who are undergoing this treatment get very tired of it. Also, you

My understanding of the intent of the analysis was to find items which
were most affected, not a test for an omnibus effect across items.

I just want to make a simple point: If one had read the NY Times
article, then my comment about yellow soup and chocolate milk
might have seen less "over the top" because:

I think step 1 would still be an answer to the question "Was the change
large enough to be considered "real" or statistically reliable."
Step 2 would be to ask which of the statistically reliable changes were
largest . . . perhaps an estimate of effect size and rank ordering of the
questions. Out

Ah, TIPSTER minds think alike! I just sent off the possibility of the Phi

There are also ways to compare whether two r effect sizes are significantly

There is no bending of the assumptions because incorrect/correct is not
