I have the mathematical ability of a marmot and yet my Erdös number is apparently 4.

This. Most "high impact factor" journals publish some absolute BS nonsense and "low impact factor" journals publish stellar stuff. If you want to base your evaluations of an article on citations (please don't) then base it on the citations that the article garners - not on those of other paper.

If there is a club for people like us I want to be a member. I promise to limit all meetings to five minutes and everyone gets to tell someone to STFU once a year.

Go home APA - you are drunk. Just got an e-mail from an APA journal reminding me that my review was due on 25th October and that it is now -5 days late.

I've learnt far too late that the secret to being a "successful" academic is making one finding or phenomenon your entire identity and then just cudgeling that thing to death for the next 40 years. Ideally you should be able to report at least 100 p-hacked 2x2 ANOVAs.

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.

Next time an institution tells you how seriously it takes research misconduct, ask them if it's *this* seriously. www.bmj.com/content/297/...

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.

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.

Why is this not getting more attention in my academic feeds. A professor got doxed and death-threats, tried to leave the US, and is not being allowed to. Connect the dots.

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.

Brown County is not too far away and has some lovely walking trails in the woods and Nashville is a cute town with a lot of artist galleries.

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" ™.

United States academic landscape got you down? Apply to join my lab at the University of Regina in Saskatchewan, Canada!

I’m planning to accept a graduate student in Clinical Psychology. Additional information:

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.
