I don't recall ever hearing someone call themselves a technologist (outside some qualified form in a medical field) but in the past couple of weeks I have come across several accounts on here self-describing as such. Have I been living under rock or is this some kind of recent trend?

You can now watch Jeremy's excellent talk on the term "association" and what it's even supposed to be referring to on YouTube. Must watch if you're doing associational research!

I've been trying to verbalize this sentiment for a while now and this comparison hit the nail right on the head. The technology won't go away, but it seems hard to believe that the current pervasiveness will be the steady state we settle into.

Not an original thought, but for *reasons* this morning I am feeling intensely aware of the fact that the ability of spreadsheets to simultaneously serve as data entry, storage, and processing devices is the key to both their widespread use and the near-certainty of their footgunization.

Just recently I became aware of the use of p-value scatterplots to discuss replication and a flood of questions about the practice came to my mind. Absolutely perfect timing for this study to come out!

Going through Altman's old statistics notes. This one is brilliant. It clearly shows why testing in low likelihood situations leads to so many false positives. The thing that is striking is how brief these are. i.e. you don't need lots of words; just the right ones.

Maybe a related thought: with colleagues, we discuss a bit that the first two years or so of an UG maths degree is very "greatest hits": you see important and enduring definitions and results, and they've been distilled over time to have "good" proofs of themselves. This is an achievement.

I don't know if this is advice anyone still gives out today, but I had it in the back of my mind that project-as-package was a thing at some point. Gave it a shot late last year for a replication package and my conclusions were very much in line with this post:

Before I Sleep: Project as an R package: An okay idea
The overarching problem I see with conforming analysis to the package domain, is that it introduces artifacts not of the project domain and that makes the project harder to comprehend

Nice clear presentation of commonplace meta-analysis failure mode: Pooling coefficients that mean different things, because original models had different adjustment sets. A coefficient gets its meaning from the whole model, not just from the predictor variable it multiplies.

Very cool (from Ehm-Gneiting-Jordan-Krüger, JRSSB 2016): for mean estimation, all consistent scoring rules can be obtained as conic combinations of 'extremal' consistent scoring rules, with an explicit structure. Similar results hold for quantiles (and perhaps other tasks as well!).
