Jan Lorenz @janlo.de · 04/09/2026I was referring to the original post's idea of less implications through AI GDP growth + share of labor shrinking. Sure, climate cost is relevant and likely supersedes this question soon, but that's a different story, and the post was not claiming that this GDP growth will really happen. 100
Jan Lorenz @janlo.de · 04/09/2026I have no clear assessment of whether the claim as such is realistic. For me, the interesting point was that, even if we believe in the growth potential, the effect need not be that drastic. 100

Jan Lorenz @janlo.de · 26/08/2026Thanks for this! Also "All models are wrong, but some are useful." has value. It doesn't give the reason explicitly (truth is bad category for models). However, it provides an answer to the (irrelevant) truth/correctness question. You can agree on "wrong" and move to the purpose discussion. 110
Reposted by Jan LorenzJulia 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

Jan Lorenz @janlo.de · 15/05/2026I guess it was always somehow like this, but on changing metrics. I think this perception is built by seniors emphasizing with their brilliant young colleagues and those brilliant juniors envying and admiring tenure. Both ignore survivorship bias. 010
Jan Lorenz @janlo.de · 07/05/2026The circular order of dimension must have meaning is what I meant. 010
Jan Lorenz @janlo.de · 07/05/2026Sure, but the critique does not apply so well to my case. Radar charts only make sense when there is a clear theoretical (and at best empirically plausible) meaning. Also, one must not search meaning in the area (when there is not fill color). This is complicated to interpret and rarely useful. 110
Jan Lorenz @janlo.de · 07/05/2026Yes that is how it is used. I don't get the small multiples idea. 010
Jan Lorenz @janlo.de · 07/05/2026Opposing dimensions rarely go together, although it is possible. The closer dimensions are the more likely is values are similar. So typically social Democrats have a bubble left. Capitalist liberals top right and anti migrant conservatives bottom right. Without radar structure this value vanishes. 000
