Hi everyone,

I wanted to send along the bonobo paper! Maybe we could discuss this if no one else has any exciting things they wish to discuss?

Subject: [EvoPsycLab] the model, and haircuts

Hi Bruce - I really like 'hidden talents'.   I realized in the shower this morning why I think I responded as I did to the diagram.  I am familiar with SEM and path models, and so that was how I read it -- despite this being a high-level theoretical model, it made sense from that perspective, and the relationships between the variables are understandable on their face, with some familiarity with the literature.

And so from that viewpoint, it was odd to see letters -- rather than path coefficients or a +/- if a hypothesized model.  In any such model, there will be different explanations underlying the relationships, but we usually don't include them in the diagram, they have already been explained in the text.  In one of ours, we also have basically 3 columns, with one explanation for the upstream mediation and another for the downstream mediation, but the explanations are not labelled.
I also think that the only purpose of figures is to explain things that are easier to understand graphically.  And so the best figures are those where captions are not be needed to get the gist of it, rather to expand on that gist.

Of course, this is also why you need different eyeballs on it, and to think about the audience, since their perspective coming into it will differ.

Also -- here is "the device" for cutting hair:  https://www.combpal.com/

Alan gave it a thumbs up and I like what he did with it, although frankly I love longer hair on men so I might have to lose it for him.

for some reason struck everyone who saw it as hilarious - it's kind of like an out-take from The Big Labowski.
