Trying and struggling to understand this perspective. I’ve watched longer talks by Shiffrin and still don’t get it. https://featuredcontent.psychonomic.org/complexity-of-science-v-psprereg/ …pic.twitter.com/XAADkgdIg0

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.
What I can say is I am using a logistic regression like I would use a neural network to model the participants (which BTW are already incredibly similar mathematically).
I actually used vanilla logistic regression as a cognitive model just the other week. The reason I'm mentioning this is to make the gap between what I actually do as a modeller and what non-modellers think I do smaller.
