A statistical model is supposed to be an expression of your a priori beliefs of the system. If you have hypotheses then that, by definition, means you have a priori beliefs about the system. The way you test your hypotheses is by building a model that contains a mechanism to test those beliefs.

It so pervasive that I'm thinking I need to write a paper entitled "Why model selection is (almost) always a complete waste of time". Maybe @bobohara.bsky.social would be up on the soapbox with me here.

Over the last two weeks I have been asked many times by people what they should do if the 'best performing' model as selected by AIC/VIF analysis/Forward selection doesn't include the effects that represent their hypothesis. My hot take has been to say model selection is almost always a bad idea

Extremely interesting opinion piece by MacIvor & Irwin on "Mail-order solitary bee cocoons as a gateway for biological invasion": doi.org/10.26786/192...
