BUT shared code is often hard to run. doi.org/10.31234/osf... Let's walk through it 🧵 4265113

Julia Haaf @juliaha.bsky.social · 26/08/2026Agreed! Sometimes the quote is slightly misused in discussion as an evasion strategy without actually addressing the subtext. Oh, you think my model is wrong? Yeah, but all of them are wrong. I think all the other things he said about models as abstractions of the world provide more advancement. 000
Julia Haaf @juliaha.bsky.social · 26/08/2026"...since it springs from a physical view of the behavior of gas molecules. For such a model there is no need to ask the question “Is the model true?”. If “truth” is to be the “whole truth” the answer must be “No”. The only question of interest is “Is the model illuminating and useful?”." 100
Julia Haaf @juliaha.bsky.social · 26/08/2026"... For example, the law PV = RT relating pressure P, volume V and temperature T of an “ideal” gas via a constant R is not exactly true for any real gas, but it frequently provides a useful approximation and furthermore its structure is informative..." 100
Julia Haaf @juliaha.bsky.social · 26/08/2026Sorry, it seems I forgot the alt text. The quote is: "Now it would be very remarkable if any system existing in the real world could be exactly represented by any simple model. However, cunningly chosen parsimonious models often do provide remarkably useful approximations..." 110
Julia Haaf @juliaha.bsky.social · 26/08/2026I still feel like people should quote Box (1978) instead of the other one. As I understand it, he is basically saying that “Is the model true?” is the wrong question. Therefore, the statement "all models are wrong" is the answer to a *question* that isn't useful. 2318

Julia Haaf @juliaha.bsky.social · 14/07/2026Yes, I think many thought we are either wizards or monsters. But honestly I think part of it is the long parental leave. If you have to go back to work after three months you need at least *some* sleep. There needs to be some regulation way earlier than here. 120
Julia Haaf @juliaha.bsky.social · 14/07/2026When we moved to Germany, people around us were in total awe at the fact that our 2,5 yo could fall asleep by himself and would stay asleep in his own room throughout the night. Sleeping alone and (the own) sleep quality does not seem to be a priority for German parents. 🤷♀️ 120
