A short rant-ish post about trust, mistakes, and knowing when to stop reading.
Supposedly, great minds can entertain contradictory ideas at once with ease. I’d love to think I’m one of them, but the truth is I even struggle to keep reading books on new, complex topics when the author makes basic mistakes in areas I actually do still understand. I know I shouldn’t throw the baby out with the bathwater, but it gives me trust issues: what if the author makes similar mistakes in the parts I don’t understand? 😯
I’m curious — do you have a rule of thumb for this? When do you forgive, and when do you close the book?
For example, a friend of mine once said (not a literal quote): “Treat it like a physics lecture — let ‘electrons orbit like planets’ slide, but walk out when someone brings astrology or chakras into quantum mechanics.” 🙃 Currently, I see it similarly - for me, the dividing line is whether the mistake feels like a teaching shortcut or a conceptual blind spot. If it’s a simplification to ease the reader in, I can forgive it. If it betrays a lack of rigor, I usually stop reading. But I must admit that sometimes it’s not easy to tell the difference in the moment — which is why I’m curious how others draw their line.
P.S. This rant-ish post was prompted by my recent reading on causal inference, where the author repeatedly described p-values as the probability that the null hypothesis is true. I was really surprised that an expert in econometrics can still get this wrong — funnily enough, even GenAIs these days seem to get it right (as shown by a bit of ChatGPT’s feedback on the problematic passage below).
