We are studying whether and how #parentalLeave is shared in different types of families, how the use of parental leave has changed in different families since the 2000s, and how parents’ social environments influence their leave uptake.

My video about how LLMs are not search engines has led to many, MANY comments telling me that I should be using Perplexity. Some insisting that Perplexity does not hallucinate.
Out of a list of 26 papers it just provided me (in "Research" mode) 4 were real. FOUR. 85% hallucination rate.
And people pay for this.

Mutta tullien _nostaminen_ 15 %:iin ”suurin kauppasopimus koskaan”?
Sopimus USA:n kanssa on Euroopalle huono, ja se, että se olisi voinut olla vieläkin huonompi, ei tee siitä hyvää.
Kuvastahan se selviää, pitää varoa kun korit kopittelee keskenään.

Or Julia finally takes over as promised for years ;)

But it is not possible to create a paperclip using for example helium atoms, while paperclip made of sodium cannot hold paper sheets together, and thus is does not comply with the definition of a paperclip.

2) Shouldn't Article 5 imply that NATO countries can spend less, not more, on defense than others, since all members should help in case of an invasion?
Title and first sentence of the paper "Probabilistic functions of finite state Markov chains" by T. Petrie (1969): "This paper is statistically motivated; the content mathematical. The motivation is this: ..."
I'm often struggling with first sentences of Introduction when writing a paper. Perhaps I'm trying to be too fancy and should just go with "The paper is sociologically motivated. The content statistical." for one work in progress. #stats #metasci #sociology #AcademicSky
