interestingly we can switch "any job" with "the same job" to scientifically determine that the number of famous nepo babies is exactly 150703

and actually i think "number of people with a job whose parents also had any job" is a better proxy than grandchildren since plenty of people dont have their parents listed. this is 1162370 for a BPP of 9.25%. this is my final answer.

i think it would be slightly more accurate if our denominator was "number of people with jobs" but thats 12561252 giving a BPP of 5.06% so not too big of a difference

ok so "number of grandchildren with jobs" is a pretty good proxy for what we are lookin for and yields 635971. so the BPP should be roughly 4.95% which i think sounds pretty reasonable

i think its not really a good representation of what we are looking for but the query for "number of people" yields 12854871 and the query for "number of grandchildren" yields 2191740.

i guess when i browse wikipedia i am much more likely to end up on some random 12th century king named "edgar the unwieldy" or somethin than i am to end up on a marlins first baseman from 1994. but that is only sayin somethin about me and not wikipedia as a whole

i was definitely overestimating how many pages there were for historical figures vs contemporary. apparently living people make up around half of all pages for individuals

this would be an undercount of the BPP probably but it would be a good starting point at least. a kind of "meritocracy is at least x% not real"

Wikidata:SPARQL tutorial - Wikidata

ooo i think it might be possible to answer this question with www.wikidata.org/wiki/Wikidat... . though it seems like it might need to be rephrased to something like "people with parents that also have parents (within the database)"

but based on my random wikipedia scrolling i think i underestimate how the number of people remembered by history is actually dwarfed by random baseball players. so the BPP might actually be pretty low. but i think if you excluded stubs for minor pro sports ppl it would be surprisingly high

maybe somebody has done it and cuz google sucks now i just didnt find it. the AI summary however said that the blue parent percentage (BPP) would be very low. i thought thats mostly wrong with the reasoning that lots of famous historical people were members of hereditary royalty or aristocracy.

watching the most recent great @acollierastro.bsky.social video and wondered what percent of people with wikipedia pages also have at least one parent with a wikipedia page. i figured someone may have already checked this but it seems like no. got 3/10 blue parents when going to random ppl pages

'An internal document named β€œOPSEC”' is a very fun start to a sentence in the intellexa leak article.

fun little bit of code in CoreFoundation when you attempt to call addObjectsFromSet: with a non-set argument. it warns you 64 times while adding to "checkForAndForgiveClientSin" with the error message also including "Please wait while the system corrects this..." like its gonna take a minute lol
