Lovely. My dad was the same and he never had a father growing up, but somehow he knew to give us that absolute certainty in our childhood.

Next time an institution tells you how seriously it takes research misconduct, ask them if it's *this* seriously. www.bmj.com/content/297/...
In 1916 the BMJ published an article about the work done by James Shearer, an American physician working in the British Army as a sergeant (because he had no British qualification). He had described a "delineator" which was better than x rays for portraying gunshot wounds. This caused a sensation and a lot of interest — but on investigation the work was found to have been invented. The BMJ published a retraction, but Shearer was tried by court martial and sentenced to death by firing squad.

Agreed but I'd also note that for many of us none of it really matters anymore. Higher ed is just broken. I can get stellar reviews on all my performance dimensions every year and still see my inflation-adjusted salary decline almost every year. I earn less now than when I started out 20 years ago.

d= -.5 when you draw your sample from the population of 5-year old boys.

Depends a bit on your sample characteristics but I'll guess d=2 just because some of those questions don't really capture "desirability" very well.

We have armed secret police kidnapping people off the street based on the color of their skin.

When we win: we will haul them before a Senate committee. The masks will come off. There will be consequences.

As someone whose taught at four different US universities over a 20 year period I can state with some confidence that the "talking to peers" stuff doesn't really happen here either unless you happen to be in a department where multiple researchers study the same topic.

100% agree. But how does one actually develop a network of identiable peers? In 20 years post-PhD I have honestly never had a face-to-face conversation with a peer about my work.

Only very serious management scholars get to conduct an experiment that shows no difference between the treatment and control group and then report that the treatment had an effect because of "mediation" ™.

I sure hope that all those psychology academics making fun of the causal claims made by Trump et al about the Tylenol - Autism observational data will stop reporting mediation analyses based on observational data. I'm not holding my breath.

Does anyone know if the International Cognitive Ability Resource is still active? I've been hoping to get access to some of their resources but have not heard back after applying a week ago. If not, is there another resource for open-source cognitive ability assessment that someone can point me to?
