A more common example for me at work is getting a response from url. Then you gotta process it further like response.json() or response.header or response.text etc etc. and then again select the necessary array index or doc value from it. Giving a name like pre_result or result_json etc etc would just become cumbersome.

I would never do `response = response.json()`. I use it when it's effectively the same type, but with further processing which may be optional.

Depends on how clear it is.

I usually write code to help local debug-ability (which seems rare). For example, this allows one to trivially set a conditional breakpoint and look into the full response:

    response = get_response()
    response = response.json()

The fact that the first response is immediately overwritten proves to the reader it's not important/never used, so they can forget about it, where a temp variable would add cognitive load since it might be used later.

and I think is just as clear as this:

    response = get_response().json()

This motivated by years of watching people through code, and me working with deeply non-software engineers, and is always very much appreciated.

    get_response().json() 

is ideal, and I'm assuming yoiu're writing an HTTP wrapper since decoding JSON is a sensible default.

If you need to add an intermediary variable, name it as clearly as possible:

    raw_response = get_response()
    response = raw_response.json()

I strive to write code that reduces cognitive load. To me, putting it in a temp variable is more of habit of old languages, mixed with a bit of cargo cult.

If you do want an intermediate variable, naming it non-deceptively will reduce cognitive load. If you don't want one, that's fine too. There's no deception with a name that doesn't exist.
