I think our field mostly operates on the "truth" assumption, but runs to the "scratch pad" one in defense against things such as failures to replicate.

So Rich is more math psych. And I understand him. I really struggle to understand the perspective(s) of social/personality psych people quite a bit and often have to ask for more context. When I get it, I can see more about what why the position you all have is the way it is.

Could that be it? As a modeller, I totally get Rich's angle. It feels the differences could be explained, at least in part, by what we see and do in our immediate sub(sub)fields?

Yes. I’m thinking of it now, on the bus. In social/emotion the models were mostly verbal, and the experiments created to fit standard linear statistical models, your t tests, regressions, anova, what have you.

Slight tangent, but the cool thing about cognitive modelling is anything can be a model. K-means b be a cognitive novel, logistic regression can be a cognitive model. Even a t-test can be a cognitive model. Depending on what you're modelling.

I’ve never done real formal modelling, but isn’t this a philosophical divide in parts of the field, where logistic regression would be rational model, a behavioral description of data and results, and a cognitive model would relate 1:1 with some kind of psychological construct?

Rational is such a loaded word and I do not think logistic regression is rational, it's a model, but not a rational one. So short answer: no. To decide on if a model is rational you need to formally define what you consider optimal behaviour for the task...

it's a minefield and that's partially why "rational" is a bit of a weasel word. I think a n appropriate question to ask, but cannot be answered here because I don't want to say more about the task/work, is what level of analysis (Marr, for example) the model operates at.

Ah, no worries. Feel free to ask me more general questions. I really wish more people felt so comfortable/were curious.
