Research Fellowships Each year, IAST invites applications for post-doctoral Research Fellowships, which offer candidates an opportunity to devote themselves full-time to their research at the start of their careers. Fello...

It is the time of the year when I tell you about my favorite post-doc ever 👇 Unless you are allergic to the French, this one sits up there with the Nuffield postdoc (life style, productivity, interdisciplinary stimulation). Share widely! Apply! #poliscky

There are two possible explanations: 1. distribution for some traits is highly non-gaussian, 2. being average in a trait means less likely to be average in another.

No. 2 would be more interesting. To exclude 1, I would look at the percentage of people within +/-0.25sd for each trait (must be ~20%)

📣 We are excited (or should we say disgusted?) to announce the conference 'Disgust across borders' at IAST! @iast.fr

🗓️ Join us on Dec 4 & 5 for two days full of disgust research across species and disciplines.

Registration and abstract submission are open (until Aug 31): forms.gle/QBmkUB3aLDjY...

As some of you guessed, the two models are statistically indistinguishable. The answer is Model 1, but there was no way to tell from the data. I was very surprised when I first saw this. Here we show that this confounding of heterogeneity and reinforcement is general: www.pnas.org/doi/10.1073/...

My point is that the only way time enters the picture in Model 2 is through the error terms, which are i.i.d, so this pattern shouldn’t be surprising.

(Disclaimer: I know the answer to the original question.)

Interesting. Wouldn't you expect model 2 to (also?) have this property?

Did Model 1 or Model 2 generate these sequences? Why?

Model 1: Pólya urn, starting with one black and one red ball. 1 (0) stands for black (red).

Model 2: Empty probit model, random intercepts with mean 0, ICC = 1/2.
