No, I did not ask it to *make up* reasons that aren't true (that's just what they do, turns out).

"The problem with AI isn't that it can do your job. It can't. The problem with AI is that your MBA-brained boss's boss doesn't know how your job works and thinks AI can do your job at fractions of a penny on the dollar, and hears the siren song of 'maximize shareholder value'."

MBA-brain is real.

Domain-General Cognitive Ability
In subject area: Psychology
Domain-general cognitive abilities refer to cognitive skills that are not unique to humans but are present across various primate species and potentially other mammals and birds, indicating a general factor underlying cognitive performance that correlates with brain size and is associated with selective attention and working memory capacity.

Was looking into what Cognitive Scientists mean by β€˜domain-general’ cognition, and then hit upon this. This is definitely NOT how we use that term.

Tip: read the last sentence to understand what went wrong here.

Sigh.

Been uploading my papers to various LLMs and asking them to write reviews justifying rejection. It's pretty wild the things they'll say (confidently saying things that aren't in the paper that are, or vice versa). Reviewer 2 was bad *enough* in the before times.

By design, federal statistical agencies operate independently to guard against politicization of data collection and reporting.

This is an alarming and dangerous move that threatens the scientific integrity of independent statistical agencies across the government. www.wsj.com/livecoverage...

An eloquent image:

Setting aside the content under the tarp for a moment, teens were asked to make art expressing what it is like to be a teen, and the end result was a mural wrapped in a tarp by adults.

I bet a lot of teens would find this expressive of their experience.

Even if they're comparative in nature, we still don't know who/when someone is comparing to. So we're in the same interpretational bind.

1. Cartesian coordinates do not depend at all on cut points; they have inherent metric information that ordinal scales lack (that's why they're ordinal) 2. Even IF Likert scales were inherently comparative, they needn't be social, because I can compare myself to yesterday, or last year; then what?

28.07.2025 07:32 β€” πŸ‘ 1    πŸ” 0    πŸ’¬ 2    πŸ“Œ 0

Sometimes, yes, but also there's the issue of the criterion itself - e.g., why P(Hit)/P(FA) are hard to interpret but d prime is more interpretable. The ordinal model removes the dependency on irrelevant parameters. Even in the ideal case that the orig. measurement is great, it is hard to interpret.

28.07.2025 06:58 β€” πŸ‘ 1    πŸ” 0    πŸ’¬ 0    πŸ“Œ 0

I never know how to interpret, say "How happy are you (1-5)" so I don't understand why the ordinal model is more difficult; just seems like people *think* the original scale is easier. Why would numbers that depend on cut points be easier to interpret?

It absolutely makes sense that men are using AI more and seeing more job benefits, because confidently spouting nonsense in the shape of information (what LLMs are programmed to do) has always been much more of a pathway for career advancement for men than for others.
